An area of low pressure currently over Missouri will move into the Great Lakes today, bringing a warm front through the area this evening followed by a cold front early tomorrow morning. A similar situation to last week may develop, where the cold air is harder to dislodge than anticipated, which may limit the advance of the warm front. In any event, temperatures this afternoon will push into the mid 50s, ahead of the cloud cover and rain that will develop later this afternoon or evening.
Showers will continue this evening and depending on whether the warm front moves through, thunderstorms are possible as well. Showers will continue into tomorrow morning as the cold front clears the area. Total rainfall from this system will be around three quarters of an inch, with higher amounts in thunderstorms.
Clearing will commence Saturday afternoon and temperatures will rise to near 60. Reinforcing shots of cold air will move through on Sunday and Monday with highs in the mid 40s both days.
Temperatures will remain in the mid 40s as we move into the middle of next week before warming again towards the end of the work week.
