MUCAPE is rising into the 2000s even with clouds though. There's a good moisture tongue coming in from Iowa. Link to comment Share on other sites More sharing options...

Chicago Storm Posted June 26, 2020 Share Posted June 26, 2020 Per meso analysis, there is actually a good to great environment in place across E IA/N IL. All of the activity that has moved through this afternoon has been elevated, thus not disrupting the environment to a significant degree. 1 Link to comment Share on other sites More sharing options...
Chicago Storm Posted June 26, 2020 Share Posted June 26, 2020 A nice line segment has taken shape across SW WI. There is an axis of TCU from that line segment on WSW to Waterloo, and we'll likely see that unzip with time. 1 Link to comment Share on other sites More sharing options...
purduewx80 Posted June 26, 2020 Share Posted June 26, 2020 13 minutes ago, RyanDe680 said: kind of a snooze fest so far Too much cloud cover where the better forcing/winds are. As @Chicago Storm just mentioned, eastern IA thru N IL/IN will be where the best wind potential sets up. You can see the inflow jet developing in SW WI now on KMKX. That's ~60-65MPH at 10,000' (~700 mb) w/ the warned cell. There could still be a supercell/tornado threat as new cells develop near the Quad Cities along the remnant outflow/differential heating gradient.

purduewx80 Posted June 26, 2020 Share Posted June 26, 2020 Nice sounding out of DVN at 20Z. Cap near 800mb and steep lapse rates in the mid-levels. The SPC algorithm suggests if that stays the same, the convective trigger temp is 90F. Link to comment Share on other sites More sharing options...

cyclone77 Posted June 26, 2020 Share Posted June 26, 2020 Some nice towers in the northern/northwestern sky. Looks like an extension of the cells that have already taken off, and are severe warned southwest of Rockford. So that looks to unzip southwestward towards the Clinton Iowa area, and possibly further west if it keeps unzipping. Sitting at 83/72 here with a robust southwest breeze. Edit: 53kft tops on the big warned cell northwest of Oregon IL. Link to comment Share on other sites More sharing options...

AFA convective temp I'd guess the mid-level speed max and nearby MCV should help lower that a bit. 1 Link to comment Share on other sites More sharing options...

Would not be surprised if that one could clip the northeastern portions of the Columbus area only if that storm takes a right-turn. Ingredients for tornadoes are much better in northern Illinois per SPC mesoanalysis. Watch those storms west of Rochelle and Rockford as they move east, could be a concern as they approach Chicagoland. Link to comment Share on other sites More sharing options...
cyclone77 Posted June 26, 2020 Share Posted June 26, 2020 In sort of a convective hot spot at the moment. Towering cumulus filling the sky, with a large thunderhead just about to move in from the southwest, and another nice one in the northeastern sky. Getting bursts of very large rain drops from passing showers underneath some of the updrafts. This whole area is likely to fill in and organize as it heads east and through the rest of IL as the eve goes on. Link to comment Share on other sites More sharing options...
