Why are temperatures in the mid 80's in October?

It's because most of central Indiana is in a moderate drought. On one had, this keeps the humidity down. On the other hand, it allows the heat to take over.

The good news is that we should have some rain Monday night through Tuesday. That will cool us down a lot. Temperature should be in the 70's from Tuesday onwards next week. Then another cool down comes around October 20.

And who's ready for snow? The longe range computer models have snow showing up between Halloween and November 5th. We have had snow flurries on Halloween before so it's not unheard of.

Also, I am predicting that peak fall colors will occur in Monroe County Indiana on October 27, 2025.
