Wow, MSP is still in the mid-80's. I guess we know where the heart of the dome is still at.

MSP is still 84 at 4 AM CT. Their airport is right in the UHI. There have been a few times during heatwaves where MSP in the summer has been one of the warmer readings nationally in the morning hours.

Wouldn't surprise me if they made a run at 100 today, especially if they can mix out a bit with the dewps.

Regarding the possible 100 tomorrow at ORD, I'd like to see them no lower than 89 at 10 AM and preferably 90 or 91. With only modest WAA and mostly sunny skies expected, the 10/10 rule should be pretty close.

Will be interesting to see what happens with the storms. If ORD gets deluged overnight it could conceivably knock a degree or two off of the high.

The low got down to 73 this morning with 0.02" of rain, but....

It's up to 89 as of 10AM, which is what it was yesterday at this time. There has been a 5F jump in the past hour.

10/10 rule would suggest 99. :popcorn:

RFD and DPA are up to 90, with 89/77 here.

After this mega torch 70's on moday is going to feel chilly.. 80's will be a piece of cake. 2/3rds of the way through July already. Summer is flying by. 3 more months and foliage will be peaking or soon be :thumbsup: Your end is nearing, warminista's :devilsmiley:

90/75 at the 11am reading. Can't see how we don't get 97+ hoping for 100+

LAF is already 95 with a dewpoint of 80 for a heat index of 115. Again one of the warmer readings in the state. Makes me wonder about possibly getting to 100...you never know since it seems like weird things happen at the station sometimes.

forecast high for downtown now at 100F... only 98F at the airport, though

93/69 now, so we are getting those lower tds

ORD has peaked at 97 and Midway 98 so far.

96/80/116 here

Just noticed that in the early intra-hour OBS. Probably will pick up a degree or so an hour until around 4, so 100 is quite possible still.

Intra-hour OBS is 97/73/108, which would bump the HI to the highest since 7/17/06 (107).

Looks like Grissom finally passed you in the dp race.

RUC has 900 mb temps of 28C in here later. If that verifies then we will get very close to 100. Wonder if we can pull out a heat index of 120... 97/82, 98/81, 99/80 would do it.
