From my northern Illinois perspective, the most surprising aspect of today's conditions, at least for me, was the higher-than-expected dewpoints. I had expected that dewpoints may reach as high as the low 70's, and mainly in the immediate vicinity of the cold front, but observations this afternoon, even from the ASOS stations, suggested that dewpoints in the mid to upper 70's were prevalent. Dewpoints were not quite at GFS-progged levels, but the NAM generally under-forecasted the dewpoints, I would say. I cannot help but wonder whether that factor alone may have shaved a three or four degrees off temperatures in this area. Of course, the dewpoints were relatively high because of the proximity of the cold front, along which moisture pools anyway, due to that low in Canada deamplifying the ridge.

Also kind of makes you wonder if dew readings would have been even higher (low 80s) if it weren't as dry as it is area wide. Around here the prominent fields of hybrid corn are already over head high, so evapotranspiration is probably nearing peak from the corn crop.

Agree, GFS appeared to have better handle on the DPs than NAM across MI and NAM was better on temps. A hybrid of the two and you would have been set!!

I will go 99F tomorrow at DTW. Take the ridiculously low max 2m temp from the GFS (84), the probably-too-high 2m temp max from the NAM (106), difference is 22F, divide by 3, and give 2/3 lean towards the NAM. I will say 104F for YIP and 98 for PTK as well.

Detroits all time high is 105F set July 24, 1934, and they have hit 104F five times. Record high tomorrow is 104F set in 1934, so we very well may not even set/tie a record even though it will likely be our hottest day in 24 years.

Looks like my joking formula of taking the difference of 2/3 NAM to GFS was spot on, DTWs high was 99F.

Definitely an historic heat-wave shaping up. Basically, the only time that it has been hotter at these sites was during the 1930's and 1988, with only a couple of exceptions.

Well at least the forecast is for nothing over 104.. Yes, upper 90s - low 100s are not much of a difference..

My poor AC is struggling to cool off the house, sitting at 79 currently..

You too? Had the landlord come out here to look at it today. "Well I bought the right size for the house, not bigger." Doh.

It really didn't feel too bad out there today, compared to some tropical Ozark summers. Those are downright repressing. The back yard was fairly comfortable... took the Kestrel out, 10-15mph breezes, and 90-100 in the shade. It didn't feel as gross as I expected.

As of 4PM the heat index at ORD is 110F.

This is highest and first 110+ HI since 7/30/99 (114).

Max HI of 111 at ORD today.

Hoosier and I had talked about what might have held back temps at LAF today, one being that we're not in center of the "deep drought" areas and closer to the "less droughty" areas and the low level flow being from the WSW. For instance, to our west and southwest, locales picked up 4.00"+ in Warren and Fountain counties a little less than two week ago. Not to forget the 1.00"+ totals that hit the southside of Lafayette last week Thursday. So it got me thinking about overlaying today's max temps at the major/legit stations on top of the last 30 day precipitation totals and % of normals maps. Not that it's a full proof explanation, but here's the maps (precip maps courtesy of the Indiana State Climatologist website)...
