Tomas Could be Bad News for Haiti

Oh Halloween how you come and go!  I can’t believe that we are kicking off November tomorrow.  Looking at October we will go down as a dry month with deficit probably close to a half an inch.  The real numbers won’t come out until tomorrow but I am thinking that it will be end up being an above average month in the way of temps but below in rain. 

Just wanted to share a link about the Hurricane that is pounding the Carribean.  Although Sept is usually the most active month sometimes we forget they can happen into the winter months.  This storm ripped through St. Lucia causing power outages, downed trees and roofs blown off. 

He will continue to move through the Caribbean eventually bring effects to  Jamaica, Haiti or the Dominican Republic.  This could be horrible for Haiti which is still in recovery mode from the Earthquake in January.  They issued the second highest storm alert, orange to warn residents.  Unfortunately most people are still living in tent cities.

Here is another article talking about what it will mean for the country.

Last year I blogged about the “perfect storm”.  Most people have heard of it since the book and movie were made.  It was the storm that formed from conditions you would only see in text books. For more info check out my blog post.

Exploring the Northwoods

After a crazy week of weather we are finally seeing a nice change.  It is cold air, espcially compared to what we were dealt earlier this week, but its seasonal so overall we can not complain!  I wanted to direct you to both Justin and Brians blogs.  After being out of the office for a few days I looked over what they wrote to just see what has been happening and really enjoyed looking at both of their.

One question we recieved during the early part of the week when we were talking about the storm that made history for the US was how can we compare it to a hurricane.  Brian did a GREAT job of explaining this. Kudos to him! It is a complicated subject when explaining to ametuers and he nailed it.

Justin also blogged yesterday about something I found super interesting.  He talked about a simple forecast compared to a detailed.  As he also wrote our job has become alot more about broadcasting then forecasting.  I think he did a real good job of showing the changes and the good/bad consequences. 

Enough about that! I wanted to let everyone know that I am going to be doing a new task here at Newsline 9.   I will be venturing out into the wilderness to give our outdoors and enviromental stories. If you have any ideas or suggestions on what I should cover make sure you send them my way.  I can’t wait to showcase what I have been working on.  Here is just a few pics I took up north that show a few areas I will be working on:

It also just happened to be the first snow fall when I was up there! Crazy how things work out sometimes:

 Last but not least! Halloween is looking spoooktacular! We will see temps in the mid 40′s with plenty of sunshine.  Winds will be light so shouldn’t add much of a chill to the air.  Overall the next week is looking very quiet.  I hope everyone has a BOOOOtiful and Happy Halloween!

Information as Cheap Commodity

Have you ever had a day when someone says something simple and rather innocuous yet in your mind it spurs deep contemplative and philosophical thoughts for days on end? No? Well, you are going to hear about my experience anyway.

A couple months ago I was talking with someone who was about to regularly receive the weather “product” generated at StormTrak9 (product=forecasts, audio, text, video). When it came to information about the wind, they said “don’t worry about the wind unless it is something major, and if it is, just say it will be a windy day”. For a lot of people out there, this is probably the way they view a lot of weather information. Most people who live a typical American lifestyle (commuting to work, living in an urban/sub-surban environment, buying food at the grocery store, receiving entertainment through a screen, etc.) the direction and speed of the wind is of little concern, yet you will still see this data on our forecast graphics here a StormTrak9. It is in our phone forecast. It is on our “current forecast” on waow.com. You might wonder why we still mention the wind given that most people could care less (unless it is significant). The reason is that our viewing area is a bit different than the rest of the country. We still have a stronger agricultural tradition. Many people (but not the majority) enjoy hunting, fishing, camping, boating, gardening, and various outdoor activities that are reliant upon the wind direction and speed. At times when we have not included the winds in the forecast, we have gotten calls and emails pleading with us to include the detailed wind information.

Because I am a meteorologist, I enjoy the outdoors, and grew up on a dairy farm, I regard the winds as highly relevant to my daily activities. It is hard to come to grips with the fact that most people do not, and the number keeps growing every year. Besides the fact that most people do not care much about detailed wind information, there is also a trend toward more personalized weather data delivery. Most of you reading this blog post know of several websites or services that will give you the wind direction and speed at the click of the mouse or the tap of your touchscreen. When you need timely information, there is no need to wait to hear it on the radio or watch for it on TV. I suppose it is nice to get that information while eating supper in front of the TV, but it is not usually absolutely necessary.

This revelation about the lesser need of wind information naturally flowed into thoughts about media and technology in general. I realize that I am in an industry undergoing a disruptive upheaval. It is interesting to view radical change from the inside but it can also be unsettling at times. I suppose it is similar to the automation revolution that is ongoing in manufacturing. Just as the horse-and-buggy, typewriter, and film camera have faded into the background, so will the traditional TV weather broadcast and all of the detailed information held within. When I started in the business in the mid 1990s, it was near the pinnacle. Most people watched TV and in Wisconsin, most people’s lives were still connected to the weather enough that detailed information was valuable. Viewers wanted to see the almanac information. They wanted to know the wind direction and speed. They even demanded to have sunrise and sunset times displayed on the weather graphics.

My how things have changed. Not only on the consumption end, but on the production end. Most of my daily routine used to consist of analyzing weather charts and producing a forecast. Now I spend more time broadcasting than forecasting. The process of developing a forecast is highly automated. In reality, I only put the finishing touches on weather information that is generated around the world every hour of the day. I use my local knowledge to increase the accuracy and relevancy of the forecast in Northcentral Wisconsin. The main challenge in broadcasting weather information in the present day is to get the consumer’s attention. There are multitude of outlets for weather information and we here at StormTrak9 try to get our forecast out into the info-sphere in as many places as possible. The other challenge is earning a living off of that information stream. As newspapers have found out, it is tough to compete with “free”. The same challenge is hitting TV. With weather information (and information in general) becoming a cheap commodity, it is harder to generate revenue. I used to be paid to produce a forecast and broadcast it on TV. I did well because I enjoy telling the daily “weather story” and I am a good forecaster. That “service” is not as valuable as it used to be (based on my salary adjusted for inflation, lol) and thus we are branching out, trying to find where people are looking for weather informati0n and in what form they want it.

The upheaval of traditional media is nothing all that special against the backdrop of technological progress – just another stone in the stream that the water flows around. You join the stream or you get left behind. I am sure many of you already have experiences with “technological unemployment” and automation (feel free to share your story in the comment section). It can be difficult to deal with if you are not prepared, and we should be prepared for even more in the near future. Our technology is being woven ever more intimately into the fabric of our existence and no one is sure how things will end up. Will more progress eventually lead us to utopia? or Dystopia? Will computers take over the world(seriously)? I’ll leave you with a quote from someone who framed the process better than me. Remember that this prescient text comes from 1997!

The Great Flood

Computers are universal machines, their potential extends uniformly over a boundless expanse of tasks. Human potentials, on the other hand, are strong in areas long important for survival, but weak in things far removed. Imagine a “landscape of human competence,” having lowlands with labels like “arithmetic” and “rote memorization”, foothills like “theorem proving” and “chess playing,” and high mountain peaks labeled “locomotion,” “hand-eye coordination” and “social interaction.” We all live in the solid mountaintops, but it takes great effort to reach the rest of the terrain, and only a few of us work each patch.

Advancing computer performance is like water slowly flooding the landscape. A half century ago it began to drown the lowlands, driving out human calculators and record clerks, but leaving most of us dry. Now the flood has reached the foothills, and our outposts there are contemplating retreat. We feel safe on our peaks, but, at the present rate, those too will be submerged within another half century. I propose (Moravec 1998) that we build Arks as that day nears, and adopt a seafaring life! For now, though, we must rely on our representatives in the lowlands to tell us what water is really like.

Our representatives on the foothills of chess and theorem-proving report signs of intelligence. Why didn’t we get similar reports decades before, from the lowlands, as computers surpassed humans in arithmetic and rote memorization? Actually, we did, at the time. Computers that calculated like thousands of mathematicians were hailed as “giant brains,” and inspired the first generation of AI research. After all, the machines were doing something beyond any animal, that needed human intelligence, concentration and years of training. But it is hard to recapture that magic now. One reason is that computers’ demonstrated stupidity in other areas biases our judgment. Another relates to our own ineptitude. We do arithmetic or keep records so painstakingly and externally, that the small mechanical steps in a long calculation are obvious, while the big picture often escapes us. Like Deep Blue’s builders, we see the process too much from the inside to appreciate the subtlety that it may have on the outside. But there is a non-obviousness in snowstorms or tornadoes that emerge from the repetitive arithmetic of weather simulations, or in rippling tyrannosaur skin from movie animation calculations. We rarely call it intelligence, but “artificial reality” may be an even more profound concept than artificial intelligence (Moravec 1998).

The mental steps underlying good human chess playing and theorem proving are complex and hidden, putting a mechanical interpretation out of reach. Those who can follow the play naturally describe it instead in mentalistic language, using terms like strategy, understanding and creativity. When a machine manages to be simultaneously meaningful and surprising in the same rich way, it too compels a mentalistic interpretation. Of course, somewhere behind the scenes, there are programmers who, in principle, have a mechanical interpretation. But even for them, that interpretation loses its grip as the working program fills its memory with details too voluminous for them to grasp.

As the rising flood reaches more populated heights, machines will begin to do well in areas a greater number can appreciate. The visceral sense of a thinking presence in machinery will become increasingly widespread. When the highest peaks are covered, there will be machines than can interact as intelligently as any human on any subject. The presence of minds in machines will then become self-evident. – Hans Moravec

Have a happy Halloween weekend! Meteorologist Justin Loew.

Tree & Power Problems

The wind has finally calmed down and now the clean-up can continue without any worry about additional damage. The weather will remain breezy today but not as bad as the last couple of days. West-northwest winds will gust up to 30 or 35 mph today but diminish by late afternoon. Many thousands of customers are without power yet this morning, which might include my house. A tree near the alley behind my house was blown over Wednesday morning and hung up in the branches of another tree and the multiple wires/cables that run through the alley way.

Old Glory Toppled, picture by Ray and Tammy Sondelski

It was not on my property but might have been on our neighbor’s property. I say might because I can’t be sure if the alley-way is considered city/county property and if the tree was growing on the alley-way. Does anyone know how unpaved and unused (for traffic) alleys are attributed? Do they belong to the city? Or the property owner?

In any case, this situation did bring up a dilemma. WPS was so busy with outages in the state that they were not taking any additional phone calls. Therefore, I moved on to calling a “city official/office” that has the capability of responding to and removing downed trees. Even though the tree was threatening to snap cable, power, and telephone lines and threatening damage to city property (a large fence), they would not touch it because it was on private property. Apparently, the city will not do anything unless the tree is growing on “city property”. I can see the rationale for this. However, government officials were the ones who granted permission for the poles and lines/cables to be strung through this area. I thought they might bear some responsibility for making sure they are maintained.

Not only does the city not want to touch the situation, the cable company is unlikely to lift a finger either. Earlier this year, after the big thunderstorm winds in July, some large branches were resting upon the cable line. I was worried that they would eventually snap. I called the cable company and alerted them to the problem. They said it was not their problem and that I should call the city. I didn’t call the city at that time, but I now know that they won’t take care of it if it is from a tree on private property. That makes me wonder if the cable line would snap, is the property owner liable for damages (and for the loss of internet/cable of all the neighbors)? In the case of the power line on the same pole, it appears that the power company is responsible for maintenance and they cover all the costs of clean-up. Even this has limitations though. Three years ago, a large snowstorm brought tree limbs down in my yard and some of them fell on power lines. They did not break the lines but the limbs did weigh down the lines enough for the power company to make a trip out to my house. They removed the branches on the power line but they wouldn’t touch other large broken branches in the tree that were about to fall onto the lines. Another gust of wind would have brought these down quite easily. The power company wouldn’t touch the other branches because of liability concerns. They were worried that the additional removal might damage some part of my property. So it was up to me to dislodge the other large broken limbs (up to 8 inches in diameter). I climbed the tree and nudged the limbs out of their precarious position. The largest one fell onto the powerline (a potential problem that I pointed out to the power company personnel before they left). It was heavy enough to stretch the power line from about 18 feet into the to about 2 feet above the ground. Amazingly, it did not snap. The branch rolled off and the line snapped back into the air. Lucky for me, otherwise I would have had to call the power company back again. A couple lessons I have learned: For difficult debris removal, call a tree removal expert, and don’t grow tall trees on your property near “public” utility lines/cables because you never know if anyone will remove the storm damage or if you will be liable. Good luck to everyone else out there who has to deal with tree problems.

The good news is that the wind has died down and it looks like a tranquil weather pattern will continue through the weekend. This is good news for trick-or-treaters. We should have partly cloudy skies, light winds, and high temps in the upper 40s on Saturday and Sunday. 

Other good news is that the 0.93 inches of precipitation we received on Tuesday was enough to push our total for the year above normal! This is the first year since 2002 that Wausau has recorded above normal precipitation. Yay! The total now stands at 34.04 inches. The normal for Wausau is 33.36 inches. If we receive normal precipitation for the rest of the year we will end up with about 37 inches. The recent rain also finally erased all of the drought across the state. What drought, you say? Oddly, the US Drought Monitor has been indicating 0.1 percent of the state in abnormally dry conditions for the past month. I see in today’s report that we are 100 percent drought-free. Time to celebrate because this does not happen too often.

Have a fine Thursday! Meteorologist Justin Loew.

Midwest Storm Vs. A Hurricane

The massive Midwest storm has certainly lived up to it’s hype.  Winds over 60 mph pummeled  the area this morning.  Winds over 70 mph were reported in the eastern half of the state.  What made this storm impressive was it’s record low pressure.  The storm bottomed out at 955.2 mb in Bigfort, MN.  All you need to know is …That is crazy low!!!  In fact this is the lowest pressure ever recorded by a non-tropical storm in U.S. History! 

The pressure reading of 955.2 mb is comparable to a Category 3 Hurricane!!  A CAT 3 hurricane has peak winds 111 – 130 mph around the storms center.  Many of you may be saying whoa whoa whoa…if we have the same pressure as a CAT 3 Hurricane…how come the winds weren’t nearly as strong??? 

And that is a great question…

Ok pressure and wind are closely related.  More specifically.. the greater the change in pressure(pressure gradient) over a certain distance, the greater the winds will be.

Think of it this way..

From A   ——-> B  the pressure changes by 10 mb

And from C ——->  D the pressure changes by 8 mb

If both were the same distance then it would be windier between point A to B.

Here’s the key and where it gets a little tricky..

The rate of change between 2 points( or locations ) varies from storm to storm.  This variation is the difference between our Midwest storm and a comparable hurricane.  Let’s look at an example…

The first picture is a pressure map of Hurricane Wilma back in the day.  Wilma’s center winds packed a punch of 125 mph and had a very similar central pressure to our Midwest storm at 955 mb.  Lets just pay attention to the orange-ish lines which represent the different levels of pressure.  The second pressure map is our Midwest storm.  The lines we want to look at are green this time but mean exactly the same. 

With Wilma, the change in pressure is extreme right at the storms center where you can see the pressure lines are really tight.  The change in pressure then tails off big time by the time you get to the storms edge.  Where as with our Midwest storm, the change is pressure remains constant, represented by the equally space pressure lines from the storms center to edge. 

And the winds directly correspond…

Winds with Hurricane Wilma(and any other hurricane) are extreme right near the center and then taper off big time on the outer edge of the storm.   And with our Midwest storm, there was a general swath of 50 to 70 mph winds from the storms center in Minnesota to the outer edge in central Illinois.

So in summary…

The Midwest Storm’s center pressure was similar to a hurricane, but the corresponding wind field is distributed differently.

All-Time Records

As Kristen mentioned yesterday, the storm system currently impacting the area is a record-breaker, not only for Minnesota and Wisconsin but also the entire U.S. The record has not yet been certified but the preliminary indication is that the pressure reached a low of 28.20 inches of mercury in northern Minnesota yesterday. This is the lowest pressure ever recorded for a non-tropical storm (hurricane) in the U.S. Here is the best current write-up I could find about the event, including the pressure readings. Here is a cool pressure map time lapse movie showing the storm as it deepened over northern Minnesota yesterday. What you see in the movie is more lines of pressure (isobars) showing up on the map as time wentby, indicating that the storm was getting stronger. Brian left a note last night indicating this storm was the second lowest pressure ever recorded in Wausau.

Also, this is the second “all-time” weather event we have observed this year. In March we did not record any snowfall and this was the first time in Wausau’s history that there was no snow in March. Many other cities in Wisconsin observed the same conditions and the same record. In May we had the earliest temperature of 92 or greater occur on May 24th. In fact, looking back over the last decade or so, I am amazed at all the all time records we have observed. The winter of 1995-1996 brought several all time cold temperatures to the Midwest including -60 in Minnesota and -55 in Wisconsin. In Wausau we had the coldest ever daytime high temperature of 20 below zero on February 2nd 1996. December 2006 and 2008 rank 1st and second all-time in precipitation for Wausau and 2008 is number all-time for snowfall. Back in 2000 we had out earliest ever 70 degree reading, a record 76 degrees on March 7th. There are many more all-time records I could cite over the last 15 years, suffice it to say that there are a lot of stories you can tell your grandkids. I remember hearing all the stories when I was a kid about “10 feet of snow”, “huge floods”, “a trace of snow every month of the year”, and of course the major heat waves of the 1930s. It turns out we have  plenty of extreme weather in the present day as well.

We still have a HIGH WIND WARNING in effect for the entire area through 7pm this evening except for Price, Iron, and Ashland counties where a WIND ADVISORY is in effect. Wind gust could top 50 mph at times. Be aware there could be more power outages today as trees and branches could be blown down. Here are some of the higher wind gusts I have observed since midnight:

  1. Rhinelander: 60mph
  2. Antigo: 60mph
  3. Houghton (MI): 69 mph
  4. Wausau: 61 mph

The wind should diminish a little tonight and a lot by late Thursday afternoon. The good news is that the winds should be light over the weekend and temps should be in the mid to upper 40s on Saturday and Sunday. It looks like good trick-or-treating weather – or as best that can be expected for this time of year in Northcentral Wisconsin.

Some of you might be seeing some snowflakes falling this afternoon and tonight. Perhaps some of you are thinking that the first snowfall contest could be won. Don’t get your hopes up if you predicted October 27th or 28th because even if some snow does accumulate in Wausau tonight, it is highly doubtful we will end up with an inch – which is the criteria for this contest. It looks like we might have to wait another week or two before another shot at significant snow.

Have a nice Wednesday! Meteorologist Justin Loew.

Historic Day for the USA!

There is so much information to talk about tonight! We have been looking at wind gusts and pressures because these two factors go hand in hand.  I tweeted earlier today ( If you are on twitter feel free to follow me at KConnolly_waow) “For the weather novice=the lower the pressure=the stronger the storm=the higher the winds”.

That is the easiest way to explain why us weather geeks are obsessed with this storm.  Today in Orr, MN we saw the LOWEST ever recorded non-tropical pressure in the mainland United States.  The pressure was so low to could be compared to the pressure of a major hurricane!!!  The pressure that was recorded was 28.20″.

The shear size of the storm is also amazing! It is covering half of the county.  It is not just the size of the storm but the weather that it is causing is so diverse. 

We have Blizzard warnings on the backside of the storm where cold air is pushing into the Dakotas.  Over the Midwest where we are closest to the “eye” of the storm winds have been the real kicker.  And last but not least we are seeing a line of severe weather associated with an intense cold front that pushed through us but through the Ohio Valley and now it punching towards the East Coast.  There have been numerous tornadoes reported and warned on and will continue into the overnight and early tomorrow.  We had one tornado reported and confirmed in Racine.  Here is the link to that information.  It was an EF1 with winds of 86-110 mph.  It took a path of 6 miles in length. 

So this storm will go down as a storm of the century! Not only did Minnesota break their lowest recorded pressure ever Wisconsin also hit their lowest in the state.  In Superior, WI we hit a pressure of 28.38″ which equals 961.06 mb that was just after noon today.  The previous record was held in Green Bay with a pressure of 28.45″ and was set on April 3d 1982.

More Storms in the Future?

The storm has arrived and so far (at the time of this writing), wind gusts have been as high as 44mph in Madison, 48 mph in Oshkosh, 52 mph in Mauston, and 47 mph in Wausau (at 9:19am). A few trees have been reported down in Marinette county Wisconsin and in a couple spots in the U.P. of Michigan. There is still a good possibility that wind gusts could go over 50 mph this afternoon. The wind will continue tonight and tomorrow but I expect the highest wind gusts to occur this afternoon. We will continue to update conditions throughout the day. For the latest, you can follow “StormTrak9″ on Twitter or any of our individual accounts (Justin, Kristen, Brian). You can also follow “StormTrak9″ on Facebook. Additional interesting historical information can be found at the NWS Duluth website.

Also arriving today, as if on cue, “Global Warming to Bring More Intense Storms to Northern Hemisphere in Winter” Is it coincidence that this headline is out today as a near record-breaking storm moves through the Midwest? Maybe. The potential for more intense storms (driven by AGW) has been studied in the past and I have reported these findings in the blog. The theory (condensed version) is that the contrast in temperature between the tropics and the arctic will increase (during the winter) if we experience AGW over the next century. A greater temperature contrast usually means more intense storms in the mid-latitudes. Computer models have now added a little more validity to the theory. However, if AGW happens to a significant extent, the Arctic might warm just as much or more than the tropics. In that scenario, it is harder to see how more intense storms could develop. For reference: My AGW position.

Also arriving today is the perhaps the first “environmental salvo” aimed at the fledgling commercial space tourism industry. Scientists are worried that flights to the edge of space could produce a large amount of soot in the stratosphere. Computer simulations indicate this soot could accelrate any AGW occurring over the next few years. It is a hypothetical scenario but something I am sure Virgin Galactic, SpaceX, and a few others are paying attention to. Private space exploration is a daunting enough task without having to worry about lawsuits from environmental organizations. I hope private space travel is not banned before I have an opportunity to try it out.

As if I haven’t reported enough bad news, AGW could bring more widespread lengthy drought to the developed world.

I hate to end on a depressing note so how about this: the largest solar power plant in the world has been approved for implementation in the U.S. Hooray for the U.S.! This installation had been stalled by environmental regulations (kind-of ironic, eh?) for a good portion of this year. I am glad to see it pass muster, although I am wondering how much political wrangling was going on behind the scenes. For further reading, here is a nice article on the state of solar energy progress in the present day and another about how China (due to low wages and near zero effective environmental regulations) is becoming the solar power leader of the world.

Have a good Tuesday! Meteorologist Justin Loew.

Temps… Just Be Happy You’re Even Mentioned

The big weather story over the next 24 hours will definitely be the high winds.  Starting tomorrow morning…winds are expected to gust over 50 mph across the state.  I would not be surprised if there where isolated gusts in the 60′s and maybe even 70 over the eastern half of the state.  For much more on the upcoming wind storm, check out previous blog posts and get your storm updates right here on www.waow.com.  We will be keeping you updated with the absolute latest via the web and of course on newsline 9 if live cut-ins are necessary through the day.  Power Outages will be likely and travel will be very difficult.

Ok temperatures…here is your one time to shine.  Due to the upcoming massive wind storm, I’ve had very little time to talk about the warm nights we had last night and tonight.  In fact some locations may even tie record high minimums for today.

Here are today’s official area low temperatures so far :

Wausau: 54    Rhinelander: 50    *Merrill: 55    *Marshfield: 55     Antigo: 52

Stevens Point: 55    Wisconsin Rapids: 55

Merrill and Marshfield will both tie their old record high minimum temperatures for the day as long as the temperature doesn’t drop below 55 by midnight.  I think they have a pretty good chance. 

We may see the same thing again for tomorrow.

Storm of the Century-It’s Possible!

It has been the talk of the Midwest! I wrote about it yesterday and Justin blogged about it this morning.  This storm could possibly be the storm of the season.  Articles around the Midwest and talking about how this storm is comparable to the worst storm that we have seen in the past century.  Justin mentioned that we saw a storm in 1998 that the center passed just to our Northwest over Duluth, Minnesota.  He says that this storm was the strongest recorded.  I was doing some research to try and figure out exactly what the strongest storms in history are.  Here is what I figured out:

The Nov 10th 1998 storm lowest barometric pressure reading was 28.475″ which equals 964.3 mb.  This was recorded at Duluth.

The storm that sank the Edmund Fitzgerald had a pressure reading of 28.95″ at its lowest point which equals 980.4 mb.

The “Great Ohio Blizzard” of January 1978 the lowest pressure was recorded as 28.05″ which equals 949.9 mb.

So far those are all the reading that I can come up with of storms that have been the strongest in the last century that have had readings near what we should see for tomorrow.  This in article with the pressure from the last two storms.  This is the records from the 1998 storm.

Looking at this map of tomorrow morning you can see that we are near the 960 mb.  Now this is model data so depending on how low we get will depend on where we get marked down in the record books.

Now this is “comparable” to the pressure of a hurricane but a few things to note that are completely different.  A hurricane is fueled by warm moist ocean waters.  Midwest cyclones are fueled by the jet stream.  So although readings are similar what it means at the surface and for us are different. 

What do you need to know about tomorrow?  Most of us are under a High Wind Warning espcially to the south of 29.  This means wind gusts could range in the 55 to 60 mph zone.  An Advisory has been issued for the rest of us and winds will reach gusts to 40 to 45 mph.  These winds could knock down trees, power lines and throw outdoor furniture across roadways.  These winds are near what we would see in a severe storm and will not just last for a short period but for a much longer period, almost 36 hours!  The warnings/advisories will be in place from Tuesday morning through Wednesday evening. 

We will keep you posted with all the latest so make sure to stay tuned to our webchannel and Channel 9!

PS Our first snow is in the forecast for Wednesday and Thursday!
