It was plenty humid in the 80's and 90's. I am definitely on the train that it is hotter now, but it was never (in modern times) 75/55 all summer here. Some people will not live here because of the humidity. Case in point, here is 1988 which is a random 80's date I picked. Great summer weather for a few days then MUCH worse than anything we have experienced this year. Frying Panel/Hell weather. The Low stayed 66 and above 24 days. We are literally living a cream puff summer compared to this month. 15 of the 31 highs below are higher than the high so far this July at MDT. The thing that really sends home the point, the highest Average temp this month so far has been 82.5. 10 days below exceed that number with a peak of 87...think of that, an average temp for the day of 87 which is the "normal high" for the day!!
