It may be getting warmer for your area, but mostly it is markedly cooler across the country.
I don't mean this week or next week - I mean in general. The entire country has gotten warmer. Certain trees and animals that only live in a narrow climate band have all moved north. We now have trees in Southern Michigan that only grew in Southern Ohio & Indiana 30 years ago. Trees that grew in mid Michigan are now growing in the Upper Peninsula. Growing seasons have lengthened all over the country. I have seen palm trees growing farther north than they ever have before.
Individual winters or summers will always fluctuate up and down - but the 30 year trend has definitely gotten warmer.
