Chicago is having its 7th consecutive day of 32°C-plus heat, including 5 straight days above 33°C, a new record for this late in the season. Fortunately, a cold front is marching across the prairie and promises to bring a 15°C temperature drop overnight and high temperatures in the 20s for the rest of the week.
We didn't have a horrible summer here. So we're not thrilled that the crisp, cool days of autumn have been delayed a full month. But tomorrow we can open our windows again.
