EXCLUSIVE SEVERE WEATHER INFO

11:27pm - Looking at the latest radar loops, I have a hunch that most of these storms will travel into the Quad Cities, points E of there. With a threat of severe becoming a little less likely, I'll stop the blog right here. However, if new storms break out, we'll pick things up for you. Thanks again for your positive feedback. I hope this has been a help to you...if it has, please spread the word. The more people that surf by the blog, the more we will post on it. Have a good night. -ERIC

11:05pm - Clearing up the confusion: SPC issues a NEW Severe Thunderstorm Watch centered over the Quad Cities. This watch will include Whiteside Co. and will expire at 6am.

10:54pm - There is a bit of confusion on whether or not the Severe Thunderstorm Watch still exists for NW Illinois. According to the National Weather Service in Davenport: "It sure looks like it did get cancelled on us- We're checking into expanding the new one east (or something else) to cover that line along I80 now near Iowa City."

10:46pm - New Severe Thunderstorm Watch in effect for Central Iowa until 6am. These storms will stay out in Iowa until at least 2am. Severe weather is not anticipated here in IL/WI until at least that time.

The Chicago NWS office has canceled the watch for Winnebago, Boone, McHenry, Lee, Ogle, and DeKalb Co. Davenport NWS is looking into how the watch got cancelled (inadvertantly). They say "SPC may have cleared it on us without doing the usual coordination. We're looking into this."
