A Messy Night Ahead, Especially North
ALERT DAY for this evening through Wednesday due to travel impacts from storm that will bring snow, mix, rain & wind to the region. Heaviest snow and greatest travel impacts will be north & west of La Crosse.
A WINTER STORM WARNING remains in effect from this evening through Wednesday afternoon~for about the northwest half of the viewing area. This includes the following counties: Wabasha, Winona, Fillmore, Buffalo, Trempealeau, Pepin, Eau Claire, Dunn, Chippewa & Clark. These areas have the best chance of seeing several inches of snow. Latest estimates are in the 6″ to 9″~range with isolated 12″ amounts for storm totals.
A WINTER WEATHER ADVISORY is in effect from this evening through Wednesday afternoon for Jackson county. These areas will see much less snow, due to the precip falling as rain or a mix at times. Snowfall totals could range from 1-4″. Elevation may come into play as well, so~ridge tops could get a bit more snow than valleys.
For La Crosse and points south and east… this storm will be more wet than white. In fact, little if any snow accumulations are expected, perhaps an inch or less. Higher terrain and ridge tops could see a little bit more snow.
Pre-Thanksgiving travelers: Roads across the the northern and western half of the region are expected to quickly become snow covered and slippery by mid to late evening. Travel in these areas will be hazardous and extreme caution should be used. Otherwise, later Wednesday or Wednesday night may be OK… except in areas that see several inches of snowfall. That’s because it will be windy Wednesday, which could cause blowing/drifting snow in areas that see snow accumulations. Thanksgiving Day looks dry.
We continue to watch a developing winter storm over Kansas. This storm will strengthen and move toward southern Wisconsin tonight.
Tonight is when the heaviest of the precipitation will fall… with heavy snow occurring in northern & western parts of viewing area. The precip may briefly start as snow in the La Crosse area, but will turn to a mix or rain… with mostly rain expected south and east. There could even be a rumble or two of thunder. Lows tonight will be in the low-mid 30s, with blustery NE winds 10-20 and gusts to 30 mph possible.
As colder air wraps into the system Wednesday, the precip will fall as a mix or snow in most areas… but taper and shift east around midday. However, winds will be strong from the NW at 15-30 mph, with gusts ranging from 40-50~mph in open areas. This could cause blowing and drifting snow in areas that see an accumulating snowfall. Highs Wednesday will be in the mid 30s, but temps will likely gradually fall through the day.
Looking Ahead… Thanksgiving Thursday continues to look dry with partly to mostly cloudy skies. Highs will be in the mid 30s.
Another potent storm system will likely impact our area for after-Thanksgiving travelers. It’s early to pinpoint details on this later week storm, but right now it looks like a chance of rain and snow moving in Friday from southwest to northeast. Highs Friday will be in the upper 30s.
This storm looks to be a slow mover, so rain and snow could continue to impact the region right through the weekend. This storm looks to track even farther north than the first one… so I’m seeing more rain than snow for most of our area, especially on Saturday with highs in the upper 30s to low 40s. Colder air wraps in Sunday with highs only in the mid 30s, so snow showers will be likely, but they should be lighter than the precipitation that falls on Friday and Saturday. Expect breezy conditions Saturday and Sunday as well.
Partly sunny and chilly Monday and Tuesday with highs ranging from the upper 20s to low-mid 30s. Slight chance of light rain or snow showers Wednesday with highs in the mid-upper 30s.
