Snow & Mixed Precip to Create Hazardous Travel Tonight

Strong Winds and Plummeting Temps Expected Tomorrow
CJ-2020-Winter-Alert-Master5
LA CROSSE, Wis. (WKBT) As advertised, a potent winter storm is now moving into the region. This system will bring heavy snow to northern portions of the viewing area and a mix of snow and freezing rain across the south.
For tonight, look for snow to continue as we head through the evening. Later tonight, a layer of dry air will get pulled into the system and cause the precip to lighten up a bit. This drier air will also lead to the potential for freezing rain to mix in with the snow, especially along and south of I-90. I can’t rule out some freezing rain across the north, as well. It will depend on how much dry air can get pulled into the storm. The mixed precipitation will then turn back to all snow late. But, by then, the snow should be a bit lighter. Look for temperatures to continue to slowly rise tonight, ending up in the middle and upper 20s by early tomorrow morning. Strong southeast winds at 10-20 mph with gusts to 30 mph may cause reductions in visibility with blowing and drifting snow. Snow totals will range from 4” – 9” in areas north and west of La Crosse. Snow totals will range from 3” –  6” for La Crosse and areas east and south.
 
As we head into tomorrow, look for any morning snow to end, with less than an inch of additional accumulations. However, strong west winds will ramp up during the day. They will remain sustained in the 20-30 mph range, with gusts between 35 and 45 mph, especially in open areas. This cold cause additional blowing and drifting of snow. Temperatures will start out in the middle 20s to near 30, but drop through the teens by late afternoon. Wind chills will end up below zero late in the day.
 
Advisories/Warnings… areas north and west of La Crosse remain under a WINTER STORM WARNING through 6pm Saturday evening. This is to account for the snow tonight and the strong winds and blowing snow tomorrow. Farther south, a WINTER WEATHER ADVISORY continues for the I-90 Corridor and points south and east through 6 PM Saturday. Again, to account for tonight’s snow and tomorrow’s wind and blowing snow. Overall, look for very poor to hazardous travel conditions tonight into tomorrow morning. If you plan to travel, slow down and take extra time to reach your destination.
 
By tomorrow night, look for a bitterly cold night under cloudy and breezy conditions. Temperatures will tumble into the single digits above and below zero, but gusty northwest winds will produce wind chills in the -20 to -30 range. Wind chill advisories may be needed tomorrow night.
 
Looking ahead… look for a quiet, but cold start to the new workweek. Look for highs in the single digits and teens and lows in the single digits to teens below zero. The good news is the cold spell will come to a quick end by midweek as warmer air arrives. Temperatures will climb through the 20s into the 30s for the last half of next week. With the arm up will come a chance of snow or a rain and snow mix. Precip chances arrive Wednesday, then hang around through Friday. At this time, next Saturday is looking dry and mild.
Have a great night and be careful on those roads! -WKBT Cory Malles
