A little muggy this morning

Patchy fog/haze has developed ahead of a weak cool front that extends from central Wisconsin back through eastern Iowa.  This weak boundary also helped produce a few widely scattered showers overnight.  The fog will spread across north-central Illinois and south-central Wisconsin this morning but should begin to diminish as the day progresses.  The boundary will then stall across the Stateline this afternoon keeping temperatures in the middle 70s.  An isolated thunderstorm remains possible through the afternoon and evening.
