WTF??? It's 39 degrees outside!

Damn that is cold. If it isn't bad enough, last night on the way home from Las Vegas we got snowed on outside of Ely on the motorcycles. Tonight I had to work late and then I had homework to finish up. Now it is 11:00 and I get to ride home in 39 degree weather. It is still September for hells sake! Should still be in the 50s. Went from god awful hot to frozen tundra. Where is my fall where it is just right???
