That is worse than anything i have had. Bad enough with a low of 82 and a dew of 80f. That really is like walking on Venus.

I feel so bad for. Northeast had a mild summer this time. Even today has been quite pleasant. I am glad I had to change out an entire water line of a 5 story building, and no elevator.

Atlantic, Iowa, is reporting a dew point of 91°F at 2pm.

But I think the sensor is broken.

Yes, a broken sensor, air temperature and dewpoint with humidity at 100% can't be going up in lockstep with clear skies and sun.

Here in Chicago I doubt it will even hit 90F lol its been a wack summer for heat lovers. It was supposed to be 86 today but it's only 77 F

Corn sweat' in the Midwest can cause some of the most oppressive humidity in the US

Can you imagine stepping outside to a 90-degree dew point?

The forecasts are pretty much in accord that Nashville's going to hit 100 this week. We've had a relatively mild summer so far. June and early August cooler than average with July right at average.

How can be such difference in these two areas. Kansas, and Illinois not that far. Latitude also pretty similar. Is it because of Lake Michigan?

Actually, most of Kansas is quite a bit further south in latitude than most (populated) areas of Illinois. Kansas humidity and heat are generally much more extreme due to the proximity of very hot airmasses that build over the south-central Plains states combined with being directly north of the Gulf of Mexico. You combine these two factors in addition with moisture trapped near the surface (corn fields, lush vegetation, etc), and it's a recipe for disaster. One of the main reasons I left that area was the heat and humidity, and have less than zero interest of ever going back there.
