As threatened, it hit 37°C (99°F) in Chicago today, making it possibly the hottest July 31st on record. We won't know for sure until tomorrow.
From July 1st until today the average high temperature in Chicago was 29.6°C (85.3°F), modestly above normal, but not quite like those in Jamie's and Angela's home cities, which were 32.2°C (90°F) and 32.4°C (90.4°F), respectively. As Angela pointed out, this is much more normal for Atlanta than it is for here, but that doesn't make it any more pleasant in either city.
Last year, despite an all-time July high of 38.2°C (102°F) in Chicago, the average July highs for Atlanta, Chicago, and Raleigh were 30.4°C (86.7°F), 30.2°C (86.4°F), and 33.8°C (92.8°F), respectively, which were much closer to normal for all three.
But let's review. The average daily high temperature for June in Chicago was 25.9°C (78.6°F), which I think we can all agree was much more pleasant. And, moreover, we chose to live in Chicago, not anywhere South of the 40th parallel, for precisely this reason.
Oh, and another thing: at this writing, it's 34°C (93°F) in Raleigh, 33°C (91°F) in Atlanta, but 37°C (99°F) here. So, yes, my dear Southern friends, it's really quite warm in Chicago right now.
