Rain to Snow

11:30am Update:  Snow is now beginning to fall in the Rockford Metro area.  Expect snow flurries/showers to continue on and off throughout the afternoon and into the evening.

After a weekend of rain - snow is back in the forecast.  Thankfully for today it shouldn't amount to a lot.  Maybe just enough to make things a little slick.  We're sandwiched between two areas of low pressure this morning - one that will move through northern Illinois later today and another that will move just to the north.  With the mild weather gone just like our rain, temperatures this afternoon will fall back into the mid 20s.  Thermal profiles throughout the atmosphere are all below freezing so anything that does fall will be in the form of snow.  We're not looking at anything too significant - maybe 1"-2" by the time Tuesday morning rolls around.  The first shot will come with the low that's just off to the west in Iowa.  The second will come as the main upper low spins to the northeast.  Behind this system, however, winds will really begin to pick up for the afternoon.  We'll see west/southwest winds through today before switching to northwest by tonight.  Gusts could near 30-35 MPH!  A few flurries will linger Tuesday morning but you'll notice a difference when you step outside.  Highs Tuesday and Wednesday will be in the 20s with highs Thursday and Friday only in the teens!!  Yikes!
