A Flash Flood Warning remains in effect for Green and Rock counties in S. WI and for northeast Jo Daviess and northwest Stephenson counties in Illinois.  Heavy rainfall and possibly training thunderstorms could lead to localized flashed flooding through early Friday morning.

A warm front stretches from northern Illinois down south of Chicago.  North of the front the air mass is a little more stable.  South of the front enough energy remains in the atmosphere for strong to possibly severe storms.  A line of storms have formed from near Monroe down through Sterling.  This line could be capable of producing strong wind gusts as it moves to the east.
