I’ll go over.

Go 100... you know you want to.  :devilsmiley:

If ever there is going to be a shot to tag the century mark this summer, this would be it.  Recent dryness (and little/no rain expected in the next several days) and still not so late in the calendar year where climo is really inhospitable.  

At this point I am comfortable with predicting mid to upper 90s, but not higher than that.  Numerically speaking, there is not that much of a difference, but it's crazy how much harder it is to hit 100.

LOT afd 

 

As the models have continued to slow the front, they have also
trended toward the front just sagging into the cwa late Sunday and
Sunday night, before washing out and lifting back north of the
area on Monday (or Monday night in the GEM). Guidance continues to
depict the western CONUS upper ridge developing eastward into
early next week, with rising heights into the mid-Mississippi
Valley, with persistent southwest low level flow and resulting low
level thermal ridge developing into the upper Midwest. Progged H8
temps warm to +18-20C Monday, and to +20C and warmer Tuesday-
Wednesday, with H9 temps from the ECMWF and GEM approaching +30C.
If this were to verify, it would likely produce surface temps well
into the 90s during the first half of next week, possibly upper
90s for Tuesday and Wednesday. ECMWF appears to continue to have
the best handle on likely surface dew point temps (lower than
likely over-done GFS/GEM values), supporting leaning toward
warmer/drier forecast at this distance. Have nudged NBM temps up
to low 90s for these days as these heat events are often tricky
for everything to come together, but may need to trend higher with
some significant heat in store if current model scenario plays
out.

Since Chicago's official observation site moved to O'Hare in 1980, there have been 5 instances of high temps of 96 or greater after August 20.

 

9/1/1984:  96

9/7/1985:  99

9/6/1990:  96

8/27/2013:  96

8/30/2013:  96

 

fwiw, the last time Chicago hit 100 after August 20 was on 9/7/1960.

Easily would top 100 with those thermals.

I'd feel pretty good about it in the metro area if those temps aloft pan out... especially with the recent dryness and more dry days coming.  Would probably be more questionable in outlying/rural areas.

But I have a bad feeling that ORD is going to max at 98 or 99.  Lol <_<

I went back and looked at re-analysis on several 100+ days since the late 1950's...

Common theme is the thermals at 925/850mb on the Euro meet or exceed all of the 100+ days that I checked, minus 1995.
