The_Doctor Posted April 12, 2014 Share Posted April 12, 2014 Shelfy feature approaching from my west. Storms kind of look like a bow on radar to my novice eye EDIT: Actually that is a green roll cloud. It looks really cool Link to comment Share on other sites More sharing options...

Brewers Posted April 12, 2014 Share Posted April 12, 2014 Dang I did't expect an elevated hailer moving across N IL this morning. The clear skies just south of the warm front bodes well for farther storm development later this afternoon. Link to comment Share on other sites More sharing options...
Hoosier Posted April 12, 2014 Share Posted April 12, 2014 Dang I did't expect an elevated hailer moving across N IL this morning. The clear skies just south of the warm front bodes well for farther storm development later this afternoon. Massive T/Td spreads in northern IL with dewpoints still in the 30s in some areas but it doesn't seem to matter in this case. Link to comment Share on other sites More sharing options...

tuanis Posted April 12, 2014 Share Posted April 12, 2014 popped on the cam for the incoming boomers/hail. decent amount of lightning ongoing ahead of it right now. things certainly look different out my front window than a month ago.here's the cam: http://ustre.am/16Txc Link to comment Share on other sites More sharing options...
The_Doctor Posted April 12, 2014 Share Posted April 12, 2014 Well the winds were about non-existent with the storm, but we did get a short period of heavy rain and pea sized hail. The pictures of the roll cloud aren't great since they were taken on my phone. The thing looked like it was glowing. Link to comment Share on other sites More sharing options...
Brewers Posted April 12, 2014 Share Posted April 12, 2014 Well, all this convection has prevented the warm front from moving farther north....models are keeping it south of MKE now. I'd probably watch the tail end of the MCS over C WI for additional development later this afternoon. Link to comment Share on other sites More sharing options...

Chicago Storm Posted April 12, 2014 Author Share Posted April 12, 2014 OFB just hit here at work. Main storm just a few miles north. Prescribed burn in the field across the way is somewhat out of control with gusts of 40mph+. Link to comment Share on other sites More sharing options...
hawkeye_wx Posted April 12, 2014 Share Posted April 12, 2014 Nothing over here this morning, but the widespread clouds have quickly vanished. The temp has surged to 73 and the dewpoint has risen into the mid 50s. There should be some decent fuel for storms this evening. Link to comment Share on other sites More sharing options...
