A little nub funnel developed and persisted for about 3-4 mins. Took a few crappy cell pics. Link to comment Share on other sites More sharing options...
Hoosier Posted August 24, 2020 Share Posted August 24, 2020 The 97 at ORD, which represents the hottest temperature so far this year, is the first time since 2008 that the standalone hottest temp of the year occurred in August or later. The hottest temp of 2008 actually occurred in September. Link to comment Share on other sites More sharing options...
Hoosier Posted August 24, 2020 Share Posted August 24, 2020 I dug into the 11 occurrences of 100+ degree highs in Chicago in August. 10 out of 11 occurred in the first 12 days of the month, with the one exception being August 24 (1947). All of them happened during stretches of drier than average conditions, or full blown drought in some cases. Wednesday fits the profile in that regard. Progged temps aloft are borderline territory for the century mark even on warmest guidance, but the dry conditions and seeing ORD overachieve with 97 today doesn't hurt.

Looks like Chicago hit 100 + 4 times in September. 2 of the 4 during the infamous 1953 heat wave Link to comment Share on other sites More sharing options...

Its not like August is much cooler than July so one would think it would be pretty common to have the hottest temp occur in August. Link to comment Share on other sites More sharing options...

It's particularly odd this year since June and July were very warm months for Chicago. But it goes to show that it's been more about persistent warmth than bigtime torches.

cyclone77 Posted August 25, 2020 Share Posted August 25, 2020 MLI made it to 96 today, and 95 here. Dewpoint hit 76 this afternoon here, and a peak heat index of 105. MLI had a dew of 75 earlier this afternoon. Hope we can mix dews down below 70 tomorrow. Link to comment Share on other sites More sharing options...

A-L-E-K Posted August 25, 2020 Share Posted August 25, 2020 p&c lowered to 80 for today before the heat returns. today was always the most likely fail day tho so no major surprise and should be a nice reprieve Link to comment Share on other sites More sharing options...
Chicago Storm Posted August 25, 2020 Author Share Posted August 25, 2020 It’s still early obviously... But given that activity last night/this morning made it well south into NE IL and the final cluster of activity around MKE is kicking out another OFB...90+ is unlikely across the metro. Might struggle to even get mid-upper 80’s.. Link to comment Share on other sites More sharing options...
Chicago Storm Posted August 25, 2020 Author Share Posted August 25, 2020 No way in hell that Wed's high will be below 97, imo. If I had to give a probability breakdown, I'd go something like this 97: 15% 98: 30% 99: 30% 100: 20% 101: 5%At the point I don’t see how tomorrow ends up hotter that yesterday..

Early signs on the HRRR aren't good, and thermal profiles trended a little cooler on the Euro. That is unfortunate, because ORD essentially escaped the storms overnight with only 0.03" so newly wet ground feedback would be a non-issue. On another note, it was still 82 at 4 am before the boundary came through, so it sort of gives you an idea of what the starting point might be on Thursday... possibly upper 70s.

Hoosier Posted August 25, 2020 Share Posted August 25, 2020 I would still go upper 90s at ORD tomorrow. Whether it exceeds yesterday has become more of a question mark. Not that I am expecting it to happen, but I would want to see 89-90 at ORD at 10 am to have a shot at 100. Link to comment Share on other sites More sharing options...

Chicago Storm Posted August 25, 2020 Author Share Posted August 25, 2020 91 ORD. What a rally. Clouds cleared just in time, as the boundary slowed as it crossed the airport. In this case, also a big help that the ASOS is at the furthest SW point of the airport. 1 Link to comment Share on other sites More sharing options...
Hoosier Posted August 25, 2020 Share Posted August 25, 2020 Nonzero chance that it doesn't drop below 80 Wed night/Thu morning at ORD, but I'd go more like 78-79. Link to comment Share on other sites More sharing options...

Would have been awful to interrupt the 90 degree stretch. Link to comment Share on other sites More sharing options...
