Good Evening Ladies and Gentlemen,

Well…….Did you enjoy the January thaw that we had? We got pretty much all of our snow melted and ready for Spring! NOT SO FAST! We are just entering the middle of January with at least a month and a half left of Winter. Madison is still at 4.6″ of snow to date for this snow season. We could double that total in the somewhat near future. Let’s talk what happened today first. We had a fairly strong storm system roll through. I believe it shifted a bit east prompting winter weather advisories. The rain showed up by late morning and Madison picked up .17″.  We reached today’s high temp at 10am and that was 49.7 degrees. Then we started the tumble. By 2pm 35.2 degrees. Finally, by 5pm we were at 24.0 degrees.  In less than 6 hours we dropped more than 24 degrees. Luckily, all of the falling precip moved out before it could changeover! However, the rain that did fall is now ice. You’ll need to throw some salt down.

Tonight we will drop down to about 10 degrees, but the winds will still be quite strong. NW winds 15-20mph with gusts to 30mph. This will create wind chills just below 0. Tomorrow it will remain a bit windy and cold with temps only getting up to the upper teens.

By Saturday the winds should die down and we will remain cold with high temps getting up to the low teens.

The cold conditions remain in place for Sunday and we will also see an increase in clouds from the approaching clipper type system. This system will be a long duration event from Sunday night all the way through Monday evening. Since it is a long duration event I don’t think we will see any advisories unless the totals get ramped up. The snowfall ratios will be about 20:1. Right now we are looking at a good 2-3″ event with isolated amounts up to 4-5″.  These amounts will likely change as the time gets closer. I am very confident we will see this storm for Southern WI and it WILL be snow.

 

The cold air gets filtered back into the area through mid week, before we see a warm up. By next weekend the GFS is trying to push out another winter storm and is showing us on the warm side of things again! This will change. Let’s get through the first storm before we look into other storms! I have attached the predicted snowfall maps for the Sunday-Monday storm below.
