Weekend Cool Down Followed by Possible Warm Up

Moderate levels of humidity will be felt the next few days with dew point temperatures warming into the mid and upper 60's.  But high pressure will follow a cold front Friday morning bringing temperatures down into the upper 70's and low 80's Saturday with comfortable levels of humidity.  But what happens on Sunday and beyond depends on which weather computer model you believe.

High pressure will begin to shift east and southeast late Sunday and Monday.  As it does there are some indications that a cold front will move down the western Great Lakes during the afternoon on Sunday.  This would cause thunderstorms to develop in the late afternoon and evening.  But the bigger story would be the much cooler air mass that follows on Monday.  If this scenario were to occur, highs on Monday would likely be in the upper 70's.

However, other forecast models suggest the front doesn't arrive on Sunday and the heat that builds over the center of the country, would shift east.  This would push temperatures into the upper 80's, to near 90 degrees early next week.  Right now the forecast calls for a slight chance of thunderstorms on Sunday with temperatures in the low to mid 80's Sunday and Monday.
