The heaviest snow Monday into Monday evening has been sliding south of a line from La Crosse to Green Bay, but will push a bit further north up toward northeast Wisconsin in the evening. Total snow accumulations from this system probably will range from an inch or less in the northwest part of the News 9 area to an inch or two around Marathon County to perhaps 3 or 4 inches well south and east of Marathon County. A WINTER WEATHER ADVISORY is in effect Monday evening for Clark, Marathon, Langlade, Forest, Florence Counties and all points south and east from there through central and eastern Wisconsin. Please be careful traveling Monday evening with snow and slush covered roads possible. Otherwise the brunt of the snow should move away around midnight with clouds sticking around. Lows will reach the upper 10s and northwest winds will develop later on at 10-15 mph.
Tuesday should be mostly cloudy to some breaks of sunshine. It will be breezy and cooler with highs around the lower to mid 20s. Northwest winds of 10-20 mph will add some wind chill so bundle up.
Much colder air will move in Tuesday night with lows slipping to the -0s as skies clear out. There should be a lot of sunshine Wednesday and Thursday as arctic high pressure moves through. Highs will reach just the low 10s Wednesday and mid to upper 10s Thursday. Lows could bottom out around -10 to -15 Thursday morning.
As the high pressure pushes away by Friday, much warmer air will start to move back into our region with gusty southwest winds. Highs could reach the mid 30s. In fact the mercury could even top out in the upper 30s this weekend with a mix of sun and clouds. The overnight lows should drop to around 20 degrees, not too bad!
It will stay mild early next week but the pattern is rather uncertain. Some models suggest some large storm systems nearby with plenty of precipitation. Meanwhile other models keep that south of our region. We will certainly keep a close eye on the situation for you.
Have a good evening! Meteorologist Tony Schumacher, 2:35 p.m., 17-February 2020
