Storms weaken moving into northern Illinois

UPDATE: The Tornado Watch has been canceled for all northern Illinois counties. 

A TORNADO WATCH remains in effect for Winnebago, Boone, Ogle, Lee, McHenry and DeKalb counties until 9pm, however, the severe risk has greatly diminished.  The watch was canceled for Carroll and Whiteside counties.

A severe thunderstorm warning had been issued earlier for portions of Ogle, Lee and DeKalb counties as the northern edge of a line of severe storms moved in from the south.  A brief tornado warning had been

issued for strong rotation near Mendota, IL, but that, too quickly weakened as the storm moved near Paw Paw and West Brooklyn.

As our atmosphere has become a little more stable Monday evening, heavy rain showers are going to be the main concern through Midnight.  Low pressure spinning up through northern Illinois will move overhead during the night before shifting east and northeast Tuesday.  This will take the rain threat with it by morning.
