StormTeam 8 Forecast: High 49° / Low 41°... Rain and drizzle develops tonight into tomorrow morning. A wintry mix across parts of the area tomorrow.

The region is located between a warm front to our north and a cold front to our west. While the weather tonight will remain fairly quiet, Thanksgiving Day looks a bit more active.
For tonight, look for clouds to continue. Deeper moisture will continue to stream into the region as the night wears on. The result will be a chance of drizzle or light rain early this evening, with drizzle and light rain becoming more and more likely overnight. It will remain mild, with overnight lows in the upper 30s to lower 40s.
As for Thanksgiving Thursday, that cold front will slowly track east across the area. A chunk of energy moving northeast along the front will overspread rain across much of the area. We will see high temps in the upper 30s to low 40s, but they will occur early in the day before falling into the 30s as the day wears on. As colder air behind the front moves in from the west, look for the rain to turn to a wintry mix or snow in areas north and west of La Crosse. A Winter Weather Advisory has been issued for these areas from tomorrow morning through tomorrow evening.
For La Crosse and points south, look for mainly rain through much of the day. However, I do expect to see that mix move into the La Crosse area by early evening, then points south as the evening progresses. There could even be a complete changeover to snow before ending late tomorrow night.
Accumulating snowfall forecast with this system is tricky since our viewing area will be located right along the rain/mix/snow line. As of Wednesday morning, it looks like snowfall accumulation through sunrise Friday will be minimal in the La Crosse area, perhaps a trace to 1". Little if any snow is expected in southeast parts of the viewing area with the precip remaining mainly rain. North & west of La Crosse is where we could see a stripe of 1"-2" of snow, including Mankato, Albert Lea, Rochester, Wabasha, Red Wing, Eau Claire and into NE Wisconsin. The snow or a wintry mix could make for some slippery travel across parts of the region, especially later Thursday afternoon into Thursday night.
As far as ice is concerned, most areas will see little in the way of icing, however, there may be a light glazing in spots that could cause a few slick spots, especially on untreated roads. This will be especially true north and west of La Crosse... that threat will spread into the La Crosse and south as we head into the evening.
**As always... be sure to check later forecasts as advisories, precip types and amounts may need to be tweaked.**
Looking Ahead... The precip should taper off/shift east by sunrise Friday but there could still be some slick spots for early morning Black Friday shoppers. Otherwise expect a chilly day with highs in the mid 30s with decreasing clouds.
The weekend looks dry and seasonably cool with highs in the mid-upper 30s to near 40º. Expect lots of sun Saturday, then gradually increasing clouds Sunday.
Another system will bring a chance of snow or a wintry mix early next week, centered around Tuesday. Wednesday and Thursday are looking dry at this point. High temps next week will be in the mid-upper 30s, with lows in the mid-upper 20s.
Have a great night! -Cory Malles
