Wisconsin Weather Update for July 12, 2010.

By: HaleStorm , 12:48 PM GMT on July 12, 2010

Good Monday morning!

Wisconsin Forecast Synopsis
This past weekend's weather featured warm and somewhat humid conditions along with scattered showers and thunderstorms, some of which became severe with strong winds and hail. Today a cold front is moving through Wisconsin, meaning we could see another popcorn thundershower this afternoon, although I think it will be a little less likely today compared to the scattered storms we had this weekend. High pressure moves in behind the cold front, which should keep us dry from tonight through Wednesday afternoon. There's not a lot of cold air behind this cold front, so don't expect high temperatures to drop more than five degrees after it passes, and things get warm and humid once again for the second half of our week.
