Last night of below freezing temperatures

It was a cold one this morning as the mercury fell to 27° in Rockford; the coldest since March 10th!  Lots of sunshine and plenty of dry air in place should allow for highs to rise nicely into the low to mid 50s by this afternoon. 

With high pressure moving overhead tonight winds will go calm for a short time before shifting to the southeast.  Once the sun sets tonight the temperature will likely drop quickly due to the dry air in place and calmer wind.  Temperatures could once again fall back into the upper 20s under clear skies and light winds.  As a result another Freeze Warning has been issued for northern Illinois for tonight.  This will be the last night of potential temperatures dropping below freezing.  Winds will shift around to the south and southwest going into the weekend which will keep overnight lows in the 40s and 50s.
