Currently we are sitting at the calm before the storm. This storm is a very interesting one as our temperatures are sitting above normal for mid January temps. There is a low pressure system brewing off in E CO right now that is heading our way and will be centered over E SD by tonight. This low pressure system will be pulling upper level moisture and allowing that moisture to condense into rain ahead of the system. This low will be moving right along with a cold front so behind the low there will be colder air that will change the precip chance to a mix of snow/rain instead of what will be falling infront of the low which will be rain. At 9:00AM 1-22-10 this is what the radar/surface is looking like. You can see the counter clockwise wind already even when this low is still in CO. That usually means it's going to be quite strong. I'm calling for 0.2" of ice and 3" of snow in RV IA.
The Blue and green are probabilities of ice - (Green = .25" or greater - 40%-60%) (Blue = .25" or greater - 10%-39%) Another cool thing is the light brown is a convective outlook issued from the Storm Prediction Center, we are in a low probability which is unusual for Janurary, could mean some convection leading to T-storms around our southern neighbors. Hope they have fun watching that unfold for them while we are sitting up here "iced in" HAHA.
