1:00 am Update:  The rain that is currently falling is moving into a very moisture rich environment and with storms regenerating back in Iowa, it's possible up to another 1.5", or more, could fall within the next few hours.  The image on the left shows the precipitable water values (how much moisture storms have to work with in the atmosphere).  Notice how there is a bullseye of 1.4" over northwest Illinois. 

A line of heavier rain showers extends from Freeport southward into Ogle, Carroll and Whiteside counties.  Rainfall rates of over an inch per hour are likely.  This band has been intensifying a little as it's moving east.  Heavier rainfall is expected in Rockford shortly.
