La Crosse, Wisconsin

Hello, forecast friends. We are taking our forecast express to the upper Mississippi Valley for our first forecast in December.

At 1053AM, CT LaCrosse was reporting a temperature of 22 degrees with mostly cloudy skies. There was a sharp trough angled to the southwest that divided the country in half. The ferocity of the trough was leading to overcast through the region, and a little bit of light snow throughout the north central US, however the severe angle it is taking towards the Four Corners is preventing the feature from bringing much moisture to the region. There will probably be a few flakes around LaCrosse this afternoon, but the real story is the cold high pressure behind the boundary.
The tilt of the trough aloft will make it disinclined to move off its spot. The high pressure at the surface, therefore, will be similarly rooted to its location. With the ridge holding firm, the cold air associated with it will remain in place as well. Unfortunately, this time of year, sunshine can only do so much, and despite mostly sunny skies, it will remain fairly chilly through the middle of the week.
Tomorrow – Some early flakes, then dropping temperatures, High 28, Low 3

Here is a look at the afternoon satellite picture, with a few clouds smothering Wisconsin, thanks to that strong upper level jet. And yes, Accuweather is going -12 on Thursday, while Weatherbug is going 4 above. Attribute this to the GFS, which is saying -20 (!) on Thursday morning. Yikes!

Updates 12/2

12:03AM I know this is absolutely at the top of everyone’s mind, but the precipitation has not reached Raleigh before midnight, and I am just now realizing that it hasn’t reached there by 1AM, either. Raleigh is in the eastern time zone. Maybe I should go to bed?

10:10PM The troublemaking system at the end of the holiday weekend is still causing problems. There are winter storm warnings across New England, right up to the coast in New Hampshire and Maine. No waiting around for winter this year.

Updates 12/1

5:39PM: We await the next system in North Carolina. This one is a very interesting storm, as it is working into a region where the air is already cool, and bringing even colder air further south. It’s only 41 in Raleigh right now. It’s 32 in Little Rock, where sleet is falling at this hour. Is anyone ready?
