TheClimateChanger Posted August 23, 2023 Share Posted August 23, 2023 August hourly heat index records at ORD (1946-present) and MDW (1948-present), per Iowa Environmental Mesonet data plotter (see below). Should be close to some of these numbers the next couple of days, although that 117F from 8/1/1953 is probably out of reach. ORD MDW Link to comment Share on other sites More sharing options...
TheClimateChanger Posted August 23, 2023 Share Posted August 23, 2023 Here is MKE - already starting to see 2023 make the list.

Brian D Posted August 23, 2023 Share Posted August 23, 2023 Another overcast day. No fog or mist, but temps staying in the low-mid 60's. Very Fallish wx as the southern areas bake. EDIT: BTW, my furnace kicked in this morning, so that stills works, and is ready for the Fall wx coming up quick. What a contrast lol. 1 Link to comment Share on other sites More sharing options...

That's why 1995 was one of my favorite summers. Hot but stormy for what seemed like weeks on end.

This may very well be the highest RELIABLE heat index reading on record. As noted by Tom Karl & Richard Knight, in their 1996 paper examining the role of climate change on the 1995 heat wave, the HO-83 hygrothermometer had a warm bias of at least 0.5C. This was one of the reasons they were unable to confirm any impact from climate change on the occurrence of extreme heat episodes. However, other research has found warm biases of as much as 2-3C on sunny, light wind days. The design allowed warmed air to recirculate into the housing for the sensor. I hate to bring this up since I was accused of trolling the 1988 drought thread, but ironically it was noted climate denier, Steve McIntyre, who first brought this to my attention.

Expand I think I remember that, too. One of those years in the mid-'90s (so probably that one), early in the school year, waiting for the bus in the cold rain.

Expand I will say in the interest of fairness, one thing that does call into question the NWS's claim is that they are comparing 5-minute data to hourly observations. To be fair, they probably should limit the comparison to top of the hour data since we don't have 5-minute data for most of that time frame.
