Chance of Thunderstorms Tonight

The heat will return today after a break on Sunday when the high was only 81 degrees. Interestingly enough... the day averaged cooler than normal for the first time since June 26th.  Every single day since then has been above normal.  It will be mostly sunny today, and temperatures will be back above average once again with a high in the low 90's. A cool front will approach the Stateline later today, and will be located from near Green Bay, Wisconsin to near La Crosse to Sioux City by 6 pm this evening.  Scattered showers and thunderstorms are expected to break out along and ahead of the front by 6 pm this evening.  A couple of those storms could approach severe limits with the possibility of damaging winds and large hail. Some thunderstorms may linger until after midnight as a cool front drops southward across the area.  The overnight low will be in the upper 60's.  There will be a few clouds to start the day on Tuesday, but skies will become sunny during the morning.  High pressure over Minnesota will feed in a northerly breeze around 10 mph.  Don't expect temperatures to cool down very much.  The high temperature will top out near 90 degrees on Tuesday, Wednesday, and Thursday.  A couple of systems may affect the area by Thursday, so there will be a slight chance of showers and thunderstorms developing.  A stronger system moving through the area on Saturday will increase the chances of showers and thunderstorms.  High pressure from Canada will switch winds around to the north on Sunday.  Cooler and drier air will move in from the north.  The high will be in the middle 80's under sunny skies.
