If you are reading this on September 1, then welcome to climatological fall! We climatologists use the calendar months of September, October and November to mark the season of fall in the Northern Hemisphere. It might not feel like it down here in the Southeast, but cooler weather, drier conditions, and lower humidity are on the way. So enjoy your thoughts of chilly nights, brightly colored leaves, and maybe even a campfire to roast marshmallows. We might even see those by the time winter gets here on December 1! I am already seeing some leaves fall from my tulip poplars, and my Japanese maple had a red leaf today. There are more on the way.
