You’ve probably heard that upgrades to dual polarization has finished in various National Weather Service Doppler Radars in our region including La Crosse and Green Bay. Marquette’s is currently getting worked on and Duluth’s upgrade will start next week.
The La Crosse Dual Polarization Radar already had a nice workout with some of the storms that moved through this past weekend. The meteorologists there had a good look at a hail producing storms using their new capabilities. It allowed them to be more certain of the location of the hail and size of it as well. Below is an image of some of the things they were looking at with a storm that passed through northeast Iowa. Please visit the following link from the National Weather Service for a more in depth look at how they utilized it. http://www.crh.noaa.gov/news/display_cmsstory.php?wfo=arx&storyid=82763&source=0
