Midweek Warm Up, Followed by Late Week Chill

Incoming high pressure Monday evening will allow temperatures to drop down into the low teens and single digits by Tuesday morning.  Winds will remain light through the morning, keeping wind chills above 0 degrees.  By Tuesday afternoon high pressure will have moved into the Tennessee Valley allowing winds to switch around to the south over much of the Midwest. 


A warm front from an area of low pressure moving through Canada, will pass during the afternoon Tuesday.  Clouds will be on the increase, but our skies should remain dry.  Highs on Tuesday will reach close to 30 degrees, but remain mild Tuesday night as strong south winds help keep temperatures up through Wednesday morning.


A cold front moves in Wednesday, crossing northern Illinois by Wednesday afternoon.  Moisture remains limited ahead of the cold front as high pressure works to block most of it to the south.  And by the time some of the Gulf moisture is pulled northward, the cold front will have already passed leaving us with only a slight chance for precipitation.


Temperatures on Wednesday will warm into the low 40's, before dropping into the 20's Wednesday night.  Cold air follows the front Thursday and Friday as high struggle to make it out of the low 20's.


Another brief warm up arrives Saturday (and this one could bring some snow), followed by another cold blast early next week.
