High pressure passing to our south brought the coldest morning so far this season to the La Cross area with a low of 4º. Clear skies, lighter winds and snow on the ground all helped lead to the very cold start to the day. Favored cold spots north & east saw morning lows in the -5º to -10º range.
Winds turn to the south today in the 10-15 mph range. This will help warm temps a bit with highs in the upper 20s. This morning looks sunny, but high and mid-level clouds will roll in as the day progresses.
Moisture will increase from the south tonight so expect skies to become cloudy. There could be some patchy fog as well. The clouds and a south breeze will actually cause temps to slowly rise into the low 30s by sunrise Saturday morning. The moisture could also cause a little freezing drizzle or light wintry mix overnight, with the best chances south. This has prompted the NWS to issue a FREEZING RAIN ADVISORY for Winneshiek, Allamakee, Crawford & Richland counties from 11pm tonight to 8am Saturday. These areas have the best chance for seeing some minor icing that could cause slippery roads. Area hunters, be sure to keep an eye on those roads when heading out early tomorrow morning.
Otherwise temps will actually warm to about average for a change on Saturday with highs around 40º. Unfortunately with the warmer air will come plenty of clouds and a little moisture for Saturday. This could cause some spotty drizzle during the day Saturday, along with some low clouds and fog.
Looking Ahead... The forecast models continue to advertise a more potent storm system lifting into the region from the south & west, that could impact the region Sunday and Monday. Temps will most likely warm into the mid 40s Sunday, so most of the precip would fall as rain.
Temps are then expected to drop into the low to mid 30s Sunday night and Monday... causing a wintry mix or change over to snow. We will have to keep a close eye on this system and fine tune the forecast as it gets closer to see if the region will see any accumulating snow on Monday. As of Friday morning, snow accumulations look minor, perhaps a couple inches at most. Stay tuned for updates! The storm will also really crank up the winds which could cause some blowing snow and reduced visibility.
Another system could impact the region around Wednesday of next week with a chance of light snow. This is a big travel day so we'll keep a close eye on it. Otherwise Tuesday, Thanksgiving Thursday & Friday are looking mainly dry at this time... but chilly with highs mainly in the 20s and lows in the teens.
Happy Friday and have a great weekend! Be safe hunters and good luck! -Bill Graul
