Memorial Day Afternoon Update

A thunderstorm is right over the town of Ridott as of 2pm and will likely produce brief, heavy downpours and frequent lightning as it moves northeast around 45 mph.  This storm will move near Pecatonica within the next 10 minutes to just south of Lake Summerset.  As of right now, this is the only storm in the area.







A Severe Thunderstorm Watch remains in effect for Green, Rock and Walworth counties until 8pm.

Instability continues to build this afternoon with cloud cover from this morning beginning to break apart.  Cumulus clouds in northwest Illinois have shown some growth in height with them and a thunderstorm has developed in Carroll county near Mt. Morris, Shannon and Lanark with the northern edge now moving into southern Stephenson county.  So far this is the only storm around but as a cold front nears from the west I wouldn't be surprised if a few more develop within the hour.  Still looking at the threat for wind and hail if storms were to turn severe.
