The city usually sees eight days in July with highs in the 70s or lower. Until now, the fewest number of highs in the 70s was back in 2007, when it happened just twice.
This year, the dry weather will keep the hot air in place, as it is easier to heat dry ground as compared to moist ground. We'll probably need rain if we're going to cool off.
