I back dated this to account for the past few days across portions of the region, so Hoosier can move posts here from monthly thread if wanted.

I’m guessing unlikely. Temp was only 89 still for a short time after 1pm. A good streak through this all will be hard, but at least we’ll rack up 90+ days overall. .
If we can get through today, the next biggest threat to 90+ would be on Friday. There a disturbance moving through Thursday night, that if (probably will) timing changes on it, could make for a stormy day and hinder 90+ potential. .
Obviously an OP run, but the consistency in the GFS showing almost wall to wall 90-100+ temps for the next two weeks is something. Can’t even recall that in 2012. There is a good amount of EPS and GEFS support for the ridge to continue flexing into the region, so it might be on to something to a degree. .
June 2020 finished tied for 6th warmest June on record. One of the years it tied with might ring a bell...

1. 76.2 - 1933

Some 90+ info for Chicago, given the pattern we are in and will be in for the foreseeable future...
90+ Days as of June 30th...
ORD: 9 (94 highest)
MDW: 6 (94 highest)
MBY: 9 (95 highest)
1981-2010 average through June 30th for Chicago is 4.5 days and climate history average is 4.2 days...So while not record breaking or even close to it for now, this year is already running well above average for 90+ days.
