A fairly significant squall line has developed from Cedar Rapids southwest through the Quad Cities down towards Galesburg late this afternoon.  This line has produced significant wind damage near Burlington, IA with numerous reports of trees down and power poles snapped.  The current track of the storm puts it in Whiteside County between 5:00pm and 5:30pm and closer to Rockford between 6:00pm and 6:30pm.




3:55pm Radar Update:   Storms developing to the west in Jo Daviess County and Carroll County could produce pea to nickel sized hail along with wind gusts between 40-50 mph.  Heavy rainfall likely as well.  Storm is near Savanna with another cell near Elizabeth and just northwest of Stockton.

Radar update: Storms are beginning to develop south of I-80 as of 1pm.  These will continue to lift north over the next couple of hours.  There are no warnings out for these storms just yet, but I would imagine they would be coming out shortly.

A Tornado Watch has been issued for Green and Rock counties through 7pm and for Stephenson, Jo Daviess, Carroll, Whiteside, Winnebago, Ogle, Lee and DeKalb counties until 8pm. 










We're currently monitoring two areas for potential storm development this afternoon.  A few showers have formed in northeast Iowa and southwest Wisconsin and will continue to lift north.  As of right now they are just showers but could develop into thunderstorms within the next couple of hours. The second area for concern is a little further south towards west-central Illinois and southeastern Missouri.  Thunderstorms have been developing ahead of an upper level low and are expected to increase in coverage as they track north.  It's likely a severe weather watch will be issued for parts of Wisconsin and also for Illinois very shortly.  The threat for wind seems to be increasing this afternoon; especially if storms move in from the south.  Be sure to keep checking back for further updates!
