With the passage of last night's cold front a much, much cooler Canadian air mass will settle over the upper Midwest and Great Lakes including right here in Southeast Wisconsin. Temperatures have plummeted and after highs approaching 80 degrees yesterday, we'll barely reach the low 50s today with readings even a few degrees cooler for the weekend. Look for patchy frost all across the area tonight and tomorrow night. On the positive side, high pressure takes over and ushers in another stretch of dry weather with some sunshine right through the beginning of next week.
Have a great Friday and a terrific weekend!
