Sunday Night Severe Weather Update

6:55am Update: The severe storm threat has gone down across the Stateline.  Showers in eastern Iowa pose much of a severe weather risk, however there has been a severe thundrstorm warning for one cell in eastern Iowa.  While a few showers are expected here this morning, it will be what forms later this afternoon and evening that will pose the greatest severe weather risk.  I'll have more on that coming up later this morning.


The Tornado Warning for McHenry County has been allowed to expire at 2:30am.  The storm has weakened and has not shown anymore signs of strengthening. 

Also, the Tornado Watch for Jo Daviess, Carroll, Whiteside and Stephenson counties has been allowed to expire.  I wouldn't be surprised to see the Tornado Watch cancelled further east as well once these storms move out.  Currently, there are no active warnings in place, just a lot of heavy rain and lightning.









Tornado Warning for McHenry County until 2:30am. 
Doppler radar indicated rotation within this thunderstorm near Marengo shortly after 1:45am.  This storm is moving to the northeast around 35-40 mph.  Cities impacted will be Crystal Lake, Woodstock, Bull Valley and McHenry.  Get into the lowest level of your home or in a basement.  This storm was reported with a funnel cloud from a storm chaser.

Severe Thunderstorm Warning for Ogle, Lee and DeKalb counties until 2am.  A line of thunderstorms over I-39 continues to move east around 40-45 mph.  This line has had a history of producing damaging winds in eastern Iowa as well as western Illinois, although within the past 10 minutes it has begun to show some signs of weakening.  We'll continue to monitor this storm as it moves to the east .

1:10am Update: Severe thunderstorms continue to roll through Winnebago & Boone with significant, heavy rain along with frequent lightning as well as strong winds.

Severe Thunderstorm Warning continues for Ogle & Lee counties until 1:30am. 

12:45am Update: Severe T-Storm Warning for the following:

Winnebago, Boone, western McHenry until 1:15am.

A Flash Flood Warning is in effect for Jo Daviess, Carroll, and Stephenson until 5:15am.
