3:30am Update:  Severe Thunderstorm Watch is in effect until 10am for Whiteside, Boone, Winnebago, Ogle, Lee and DeKalb counties.

2:30am Update: Storms continue to move east/northeast this morning across northern Iowa and southwest Wisconsin.  The "warm front" has lifted north overnight and the potential for some shear along the front exists...and that's why we have the tornado watch until 9am.  We'll be watching the southern edge of this complex for any development along with what almost appears to be a bowing segment trying to form just north of Waterloo, IA.  That is currently were all the severe thunderstorm warnings reside.  Another threat as storms move through this morning will be the potential for heavy rain.  Radar rainfall estimates of 1.5"- 2" per hour have been seen. 

1:30am Update: A Tornado Watch has been issued for Jo Daviess, Stephenson and Carroll Co. in Illinois and Green Co. in Wisconsin until 9am.
