Chicago WX Posted April 18, 2013 Share Posted April 18, 2013 Had some sun here earlier this morning, but clouded over now. LAF reporting clear at 9:00am is bogus. We'll see what happens when the line from IL reaches here...as it is now severe warned to the west. Winds are rather gusty though. Link to comment Share on other sites More sharing options...

Harry Perry Posted April 18, 2013 Share Posted April 18, 2013 So close, yet so far. (One county away) Seems the SPC is having high hopes for this. They were considering either a severe thunderstorm or tornado watch and they end up going with a PDS tornado watch. Not gonna lie, I wish the storms/rain that is headed this way were about 6 hours slower. Looks like that line will be here by noon. If that happens, the atmosphere wouldn't have enough time to recover and the best threat of svr wx would be south of I-80... Guess we'll wait and see what this line does, but I'm hoping it falls apart before making it here. Link to comment Share on other sites More sharing options...

Bryan Wood Posted April 18, 2013 Share Posted April 18, 2013 Part of me wants to chase, but the prospects of embedded cells in a squall line turns me off. This seems like the setup of the "discrete cells quickly being overtaken by the line" variety. No thanks. Link to comment Share on other sites More sharing options...

I dont understand calling it overkill when there's very strong shear, hodo's look great, and we've begun to destabilize quite nicely. Link to comment Share on other sites More sharing options...

Indystorm Posted April 18, 2013 Share Posted April 18, 2013 SPC discussion seems to be banking on new discrete cells forming ahead of a the line or mesovortices within the line itself for the tornado threat. Does anyone else think current line seems to be breaking up a bit on radar and the greater threat will indeed come later this aternoon? Link to comment Share on other sites More sharing options...
