I ran some numbers looking back at all of the September high temps since 1901--all 110 years worth--to check for 50 degree high temperature occurrences.
If you are heading to high school games Friday night, the temps will resemble more mid-October than mid-September. Frankly, I am ready for it.
Lots of numbers so here are the highlights of what I found:
