A warm front will lift northeast across the region early this morning. As the front moves through an increase in moisture will lead to widespread cloud cover and perhaps some patchy fog & drizzle. Some light rain could develop in spots this afternoon. It will remain mild with highs today in the mid 40s.
Tonight will be cloudy with patchy fog and drizzle. Areas of light rain will be possible as well. Low temps for most will be in the mid-upper 30s. However some low 30s are possible in far northwestern parts of the viewing area which could cause the light rain to become a wintry mix in those areas.
As for Thanksgiving Thursday, a 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 colder air behind the front will move in from the west and cause the rain to turn to a wintry mix or snow as the day progresses from northwest to southeast. This will especially be the case north & west of La Crosse. The precip could remain rain for most of the day in La Crosse and points south & east. All areas could see a change over to a wintry mix or snow by Thursday night as temps fall into the upper 20s to low 30s.
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, but a period of a wintry mix could cause some minor icing on some roads. North & west of La Crosse is where we could see a stripe of 1"-3" 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.
**This is a rather "changeable" forecast as the exact temperature profiles across the region will be key when the heaviest precip moves through... so please stay tuned for updates!**
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.
The forecast models are not in great agreement heading into next week, but there looks to be at least slight chances for some light snow or a wintry mix on Monday and Tuesday. It looks rather unsettled for Wednesday and Thursday as well, so I will keep at least small chances for some light snow or a wintry mix in the forecast through much of the week. High temps will be in the mid-upper 30s, with lows in the mid-upper 20s.
Have a nice day and Happy Thanksgiving Eve! -Bill Graul
