Some stats....MDT will end up July with only 1/3 of the days being BN (could be 11 total after today) but an overall positive departure only in the low 1's because the highs were not all that hot on average.
The highest temp was 95 which was lower than the highest temp of any July going back to 2017 when it was 93. However, the lowest temp was 65, assuming it does not beat that tonight by midnight, which was the second highest low temp ever only being eclipsed by 2020 at 67.
There were several occasions where some outlying areas were in the 50's during the month so I personally am attributing at least some of the "high low's" to HIA.
