Severe Weather Update

7:25pm Update:  Tornado Watch extended to include the counties of Jo Daviess, Stephenson and Carroll in Northwest Illinois until 10pm.

Tornado Warning is in effect for the counties of Linn, southeastern Buchanan and southwest Delware Counties just north of Cedar Rapids until 8pm.  This storm is moving to the northeast around 50 mph.


Forecast Discussion: Thunderstorms continue to develop in southwest Wisconsin and northeast Iowa this evening.  The warm front extends right over the Stateline with the surface low in Southern Iowa.  Eastern Iowa remains very unstable right ahead of the low as moisture continues to be pumped in from the south. Storms will likely continue and move east/northeast as the cold front and low track over Northern Illinois.


Severe Thunderstorm Watch for Green, Rock and Walworth Counties in Southern Wisconsin until 11pm.


The warm front continues to move to the north this afternoon with clearing behind it.  The southerly winds are pushing warm, unstable air into southern Iowa and as a result a Tornado Watch has been issued for Eastern and Southern Iowa until 10pm.  We'll continue to monitor the area as storms are already beginning to develop within the watch area.
