purduewx80 Posted November 10, 2020 Share Posted November 10, 2020 Close call for Chicago. Def a higher risk just W/NW given the timing. We will lose some instability after sunset but this could be offset a bit as shear increases owing to the LLJ accelerating to 50-60KT. Link to comment Share on other sites More sharing options...

Indystorm Posted November 10, 2020 Share Posted November 10, 2020 Yeah, and a number of NWS radars are having problems. Link to comment Share on other sites More sharing options...
Hoosier Posted November 10, 2020 Author Share Posted November 10, 2020 I think the line will hang on in respectable fashion this far east. As mentioned, we will lose some instability, but ample cloudcover and fairly well mixed low levels should keep the temperature drop rather modest in the few hours after sunset. 1 Link to comment Share on other sites More sharing options...

Chicago Storm Posted November 10, 2020 Share Posted November 10, 2020 The overall threat is still fairly isolated to some of the better cores. The broad-brush warnings are deceiving. 2 Link to comment Share on other sites More sharing options...

Chicago Storm Posted November 10, 2020 Share Posted November 10, 2020 The whole metro will end up with a nice hit from the QLCS. Still a question in how widespread severe will actually be...But it seems that over the past hour or so, it has been more widespread instead of isolated. 1 Link to comment Share on other sites More sharing options...
Indystorm Posted November 10, 2020 Share Posted November 10, 2020 This line is packing a punch for Chicago metro area due to kinematics. Mixed CAPE is less than 500, but helicity up to 350-400. Wow if that instability had been greater! Link to comment Share on other sites More sharing options...
