Weather and rainfall is often a case of the “haves” and “have nots”. It’s really strange that parts of southern and central Wisconsin have had less than 3.0″ of moisture for the entire growing season so far while parts of central Minnesota around Brainerd and Aitkin have had around 30.0″ for the growing season so far! Yes that’s right… two and a half feet of rain since April just about 300 miles away from the drought zone. I provide forecasts for some radio stations in that part of Minnesota, so it’s very interesting talking to them, and how they are hoping the rain misses them for a few days so they can enjoy more summer sunshine. I have to definitely change mind sets when talking with clients in the drought zone versus the wet zone. They have different things on their mind and opposite needs for sure.
Be that as it may, some substantial rainfall fell in northern Wisconsin early Wednesday. The image below is the rainfall estimate from the Green Bay NWS Doppler Radar. Parts of northern Price, Oneida, Vilas, Ashland, and Iron Counties had over 1.0″ of rainfall. In fact 1.8″ fell around Winchester with 1.4″ in Park Falls.
This band of decent rainfall actually started back in northwest Minnesota Tuesday night. Amounts of 1 to 3″ were reported in a strip from Grand Forks to Duluth. Doesn’t that sound nice!
Some people have been asking me how much rain would we need to climb out of the drought? Well of course it depends on where you are and how much rain has fallen in your area this season. However in general, according to the image below from the National Weather Service, it looks like the southern half of Wisconsin would need about 3 to 9″ to be come out of the drought status. Ideally that would fall over a week or two, rather than in one short burst. Obviously that would cause flash flooding and most of it would run off into the rivers rather than soak into the ground.
