A storm system is tracking through the region today and bringing a mix of precipitation to the KWWL viewing area. This is a complicated system due to the temperatures... they started just below freezing to start the day and will climb into the mid 30s to low 40s this afternoon, before dropping as a cold front tracks in.
Rain and snow track into the area this afternoon with mainly rain south and mainly snow north. Any sleet mixing into either will cut down on amounts. Any rain mixing in with the snow will cut down amounts. But all snow will produce slippery conditions at times, especially on untreated surfaces.
Right now, it appears that we all have the potential for alight glaze of ice early this morning before temperatures rise above freezing. Rain will track in, although the northern two tiers of counties may stay cool enough to be mainly snow much of the day. Areas along and north of Highway 20 will have the best potential for an inch or so of snow, with up to 3 inches or so in the far northern counties. Again, this will depend on how much drizzle, rain, and sleet mix in... all of these cut down on the amount of moisture available to fall as snow. A WINTER WEATHER ADVISORY is posted for our far northern counties where the best chance of travel headaches is located.
Temperatures will warm up above freezing across the viewing area, and this will keep precipitation as mainly rain in the southern half of the viewing area, but could be a wet, heavy snow in the north. This will melt or compact easily, which could affect snowfall amounts. No matter what, watch for slippery spots this morning and again this afternoon as temperatures will be around the freezing mark.
A cold front tracking through tonight will switch winds around to the northwest and the winds will pick up speed. Strong winds will bring steady or dropping temperatures tonight through Tuesday. This will cut off the moisture source, too, so any lingering mixed precipitation will end around Midnight.
It will be mainly dry this week, although a week disturbance may track through Wednesday or Wednesday night and squeeze out some snowflakes. It will be cold.... lows drop to around zero Wednesday morning, highs will only be in the mid teens Wednesday afternoon, and we drop below zero again for Thursday morning. We will warm up into the mid 30s for Friday and aim for the 40 degree mark for the weekend.
