To me Sun is probably the hottest day...though could even end up being Sat. By Mon the flex northward of the ridge starts breaking down, with storm chances greatly increasing. Sun could be a good candidate, with the warmest UA temps expected...Though storm activity could end up not too far to the north, or even in the area. If Sun or Mon is indeed hottest day(s), I agree ORD will surpass the season hottest of 96. If above issues come into play, it’s not happening. Also add in any precip as a issue, which could be significant, over the next several days.
