Few Storms Possible this Morning

(7:20:37 AM) nwsbot: DVN issues STRONG THUNDERSTORMS AFFECTING NORTHWEST ILLINOIS for Carroll, Stephenson, Whiteside [IL] till 7:45 AM CDT



(6:26:03 AM) nwsbot: DVN issues STRONG THUNDERSTORMS WITH GUSTY WINDS MOVING ACROSS EASTERN IOWA AND INTO NORTHWEST ILLINOIS for Dubuque, Benton, Linn, Jones, Jackson, Iowa, Johnson, Cedar, Clinton, Scott [IA] and Carroll, Jo Daviess, Rock Island, Stephenson, Whiteside [IL] till 7:30 AM CDT


(5:40:40 AM) nwsbot: DVN issues STRONG THUNDERSTORMS WITH GUSTY WINDS MOVING THROUGH EAST CENTRAL IOWA for Buchanan, Delaware, Dubuque, Benton, Linn, Jones, Jackson, Cedar, Clinton [IA] and Carroll, Jo Daviess [IL] till 6:30 AM CDT

A complex of thunderstorms is currently moving through southwest Wisconsin and northeast Iowa, just as I expected.  These storms will continue to move east through this morning but run into a little more of a stable airmass from overnight.  However, the low level jet should continue to pump moisture into these storms to keep them going through the morning hours.  I anticipate the storms crossing the Mississippi River around 6am and should be within the Rockford area around 7am/7:30am.

Once this passes this morning, more storms could develop later this afternoon as a warm front lifts north and interacts with an upper level disturbance.    These storms would pose the greatest threat for severe weather later today.
