60 degrees on Wednesday... Thunderstorms Possible Thursday...

Rockford saw the mildest weather since last Novermber 14th on Wednesday afternoon with the temperature soaring to 60 degrees. It will continue mild overnight along with fog and some drizzle in spots. The fog will be especially dense in Wisconsin and a DENSE FOG ADVISORY has been issued for all of southern Wisconsin until 9 am on Thursday. Some scattered showers may develop later tonight. It appears as if the best chance of showers will be over northwestern Illinois. A strong distubance will bring a band of moderately heavy rain showers across the area tomorrow morning through mid day. There may even be a couple of thunderstorms in that band of rain. Excessive amounts of rain are not expected because of the speed of the band of rain moving through.  After the band moves off to the northeast there may be partial clearing for a brief time as a dry slot of air pushes across the area. With very cold air aloft showers and possibly a thunderstorm will fire up again in the afternoon. Rain showers will gradually diminish by midnight on Thursday.  A large cyclonic flow will persist across the middlewest for the next several days.  Rain showers will pop up from time to time through Saturday, and may even linger with a few showers into Sunday.  Total additional rainfall may range between 1" and inch and one half.    With the recent snow melt several area rivers will reach or slightly exceed flood stage.  Crest levels are highly dependent on how much rain falls in the next 4 days, and how fast it falls.    High pressure will take control of the weather by Tuesday bringing sunshine back to the Stateline, along with temperatures close to 50 degrees.
