ALERT DAY – Fog, Drizzle, Freezing Drizzle & Snow Today

Monday’s High: 33F / Tonight’s Low: 5F – Last updated Monday, December 9, 2019 at 8:30 AM…

Even with clouds at times over the weekend, temps were mild with highs around 40F on Saturday… then mid 40s on Sunday.

ALERT DAY today due to travel impacts from light snow accumulations. Also expect fog, drizzle and freezing drizzle this morning. A thin icy glaze could form on untreated roads where freezing drizzle occurs.

Low pressure and a strong cold front are approaching from the west this morning. Before the front arrives, expect areas of fog this morning, along with some drizzle or freezing drizzle. This could cause some slick spots for the morning commute, so use caution.

As the front arrives, expect a period of snow from mid-morning through early to mid afternoon. A given location should only see about a 3 to 5 hour window of snow, so snow accumulations should be fairly light. Snow totals should range from just a trace (far south) to perhaps 2″-4″ (far north). It looks like totals in the La Crosse area could be around an inch or so. Slightly higher totals could occur across higher terrain and the ridge tops. The chance for light snow and an icy glaze in spots has prompted the NWS to issue a WINTER WEATHER ADVISORY for most of the viewing area for today.

High temps today will be this morning in the low-mid 30s, then it turns windy and sharply colder behind the cold front this afternoon… with temps falling into the low 20s by sunset. NW winds increase to 10-20 mph, with gusts to around 30 mph.

Partial clearing later tonight and MUCH colder. Lows will drop into the single digits, perhaps a bit below zero in far northern counties. W/NW winds 10-20 mph, could cause wind chills in the -5F to -20F range. This is the coldest air so far this season… by far, so be sure you and your pets/livestock are prepared.

Cold tomorrow and Wednesday with a mix of sun and clouds. Highs will only be in the upper single digits to low-mid teens. Low temps Tuesday night will be in the single digits above and below zero, perhaps even around -10F far north. Wind chills will likely drop into the -10F to -20F range.

Looking Ahead… Not as cold Thursday through Saturday, but with the warmer air will come chances for periodic precipitation.

One disturbance will likely bring light snow on Thursday, especially during the afternoon and into Thursday night. Highs Thursday will be in the upper 20s. Slight chance for a light rain/snow mix on Friday with even warmer highs in the mid-upper 30s. Another chance of snow on Saturday with highs back around 30F.

Sunday through Tuesday looks partly sunny and dry at this point, but colder. Highs look to be in the low-mid 20s, with lows in the low-mid teens.

Have a good Monday, but use caution on the roads today. -Bill Graul
