Thursday started with scattered rain showers across the Chippewa Valley and while we expect on and off rain throughout the daytime hours, it’s overnight Thursday into Friday where the heaviest rain will fall.
Winds will continue at 10 to 20 mph and gust up to 30 mph as temperatures stay in the 60’s during the day Thursday. Colder air will start to filter in early Friday and temperatures will bottom out around freezing Friday night. Wind chills will already be in the low 30’s throughout the day and drop into the 20’s by Saturday morning.
Wisconsin and eastern Minnesota still sit on the warmer side of this very large system. As it inches closer we will see our precipitation stay rain due to warmer air filtering in through Friday morning. Rainfall amounts will be in the quarter to half inch range by the end of the rainfall Friday.
Friday afternoon may be the first time we see a couple flakes, but the surface temperatures will not be near freezing until after dark. So any flakes that do fall will likely either turn to rain drops or evaporate before reaching the ground. Any flakes that do reach the ground will likely melt on impact.
Saturday will be wintry. Cold, windy, and the chance for very minor accumulations of snow will be possible, mainly to the north. Again, any snow accumulation we get will only stick to grass and accumulations will be less than an inch.
We have slight chances for flurries each day following Saturday due to the possibility of this system stalling out and wrap around cold air keeping temperatures low to start next week.
