September marks the start of meteorological fall, and if you’re anything like me, you’re ready for crisp mornings, pumpkin spice lattes and sweater season. But who will actually get it?
Here’s a look at what to expect in September, according to the latest outlook issued this week by Atmospheric G2 and The Weather Company.
Temperature Highlights
-Crisp, Cool East: Much of the East will start to enjoy fall weather with slightly below-average temperatures this month. This cooler pattern stretches from Pennsylvania down through Texas. For reference, typical September temperatures can be seen at the end of this article.
-Toasty Rockies, Northwest: Meanwhile, the West has a different story. The Rockies and Northwest can expect above-average temperatures, with the Northern Rockies getting the short end of the stick with the most above-average temps.

Precipitation Highlights
-Soggy Southeast: Although the Southeast will be treated with cooler-than-average temps, it comes with a drawback — more rainy weather. Above-average precipitation across parts of the Gulf Coast and Southeast could be related to tropical activity as we enter the peak of hurricane season.
-Dry West, Central Plains: On the other hand, a big region of the West and Central Plains is expected to be drier than average, on top of their warmer-than-average temps.
-Rainy Pacific Northwest: Not only will the Southeast see a rainier September, the Pacific Northwest is also expected to be wetter-than-average, as they leave their drier months behind.

-Much of the Northern Tier: From Montana to Virginia and northward to Maine, average September highs reach the 60s and 70s. This region will see close to average temperatures this month.
