Chicago Storm Posted July 24, 2011 Share Posted July 24, 2011 Nice MCS rolling through the LOT CWA right now... Unless there is further development, it looks like ORD/MDW/Chicago will be missed to the west, with the activity pushing southeast along a southward moving OFB.

A-L-E-K Posted July 24, 2011 Author Share Posted July 24, 2011 despite missing the line to the south, comma like feature has been an efficient rain producer. On the plus side, i think this it the last round for Illinois north of I80. Link to comment Share on other sites More sharing options...
Stevo6899 Posted July 24, 2011 Share Posted July 24, 2011 Could use some of that rain in MI... Past 30 days percent of normal: Incredible how quickly my grass went from green and under water from flooding in the middle of may to almost brown and dorment now. Also its been interesting to see the storms train and dump rain along i80 to the south of here while we get nothing. I see Pennsylvania and new York aren't doing much better.
