Few showers south...Cold air to follow

A few light showers have developed around I-88 this morning as a cold front combines with a little disturbance moving out of the central Plains.  These, for the most part, will remain to our south.  Skies will stay mostly cloudy through the morning and probably into the early afternoon as a lot of chilly air is found behind the front.  As high pressure moves in later this evening and overnight winds will begin to calm - especially to our north and west, allowing temperatures to possibly fall into the middle 30s!

Freeze Warnings have been issued for all but the far southeast portion of Minnesota, northern Iowa and parts of the Dakotas for tonight into early Thursday morning.  Meanwhile, a Frost Advisory has been issued for northeast Iowa and western/southwestern Wisconsin - including Green County.  Temperatures in the upper Plains and Midwest are expected to drop below freezing almost putting an end to their growing season.  North and west of Rockford I feel will have the best shot of reaching at least the middle 30s tonight.  We'll have the same set up for Thursday night, however, a few mid-level clouds may move in and keep lows from dropping too much.  Either way the patchy frost wording remains in the forecast.  You might want to bring in any plants that you can and cover the ones you can't just to be on the safe side.
