Warmth...followed by Cold and Snow
The weather the past couple of days sure has been nice with mostly sunny skies and temps reaching the low 60s. Sadly, that will all be changing as we go into the weekend. As we know, anything can happen during the month of March; from 70s to bitter cold and snow. This weekend will be no exception. A cold front will swing down from southern Canada throughout the day Friday through the Plains and into the Stateline by Friday afternoon. As it does, clouds will increase ahead of the front with rain likely early in the evening. As the front passes Friday night, temperatures fall below freezing allowing for a rain/snow/sleet mix before changing over to all snow Saturday. A surface low will develop along the front and move through southern Illinois into Indiana by Sunday (at least that's the current track). Temperatures at the surface will stay slightly above freezing so the snow will more than likely be a wet, slushy accumulation. As far as snowfall amounts, that can get a little tricky this time of year. Since wet snow doesn't accumulate as quickly as dry snow, amounts may not be as high despite the amount of moisture with the storm. Remember the last snow we had were it was more of a wet snow and accumulations weren't too significant, around 2"- 4"? That may be the same for the weekend. Of course there is a lot of fine tuning still to be made on the forecast so be sure to keep checking back for the lastest.
