Memorial Day weather update

A Severe Thunderstorm Watch has been issued for Green, Rock and Walworth counties until 8pm this evening.







12:10 pm Update: 80% possibility a severe weather watch will be issued over Wisconsin and parts of far northern Illinois within the next hour or two.

The slight risk for strong to severe storms continues across northern Illinois and southern Wisconsin this afternoon and evening.  There have been a few sprinkles and light showers moving through, but further to the west a line of convection is beginning to develop from Iowa and Lafayette counties in southwest Wisconsin to near Galena, IL. 

The storms that are in southwest Wisconsin may develop further south as they move east/northeast as the main cold front sits back in Iowa.  Further development out west is anticipated as a narrow band of instability has developed ahead of the front.  Storm mode initially may be as individual cells but then form into a line later this afternoon.  Should we get storms to form damaging wind gusts and hail would be the primary concerns.
