Significant Severe Weather Possible Sunday in Lower Great Lakes Region

Friday is a lower severe chance, but Sunday's setup needs to be watched carefully.

A severe weather event will likely unfold somewhere in the Great Lakes Region on Sunday. Current questions remain on timing and location. After a system brings us a chance for some severe weather in the form of damaging winds and hail, a powerful low pressure system will move into an environment of high instability and high shear for Sunday afternoon. Recent ECMWF and NAM models depict a northward shift in the favorable shear, with NAM being quite bullish on instability. Expectation is that the threat will likely shift a little further south, however the Great Lakes Region should be on careful watch for this event upcoming on Sunday afternoon.
