Keep the sweaters in the closet and put the pumpkin spice lattes on hold.

Forecasters are anticipating an unusually warm fall this year in large parts of the U.S. throughout September, October and November.

Things will be particularly balmy in the Northeast and in the West, including California, Nevada, Oregon and parts of Washington, Paul Pastelok, a senior meteorologist at Accuweather, told TODAY.

“It will be fairly mild, not extremely mild, but a couple degrees higher than normal," said Pastelok. "There will be more days where you can be outside and do things.

"It doesn’t look that rough for kids who will be going back to school,” he added.

The East, South, and areas including the Northern Plains and parts of the Rockies is also likely to see higher temps, according to The Weather Company.

One area of exception is the Pacific Northwest, which could see cooler-than-average temperatures.

In Boston, for instance, the average temperature this September to November will around 57 degrees, said Pastelok.

That’s a few degrees higher than the 54.5 degree average in those months over the last 30 years.

In Sacramento, the average temperature this fall will be 65 degrees, also a few notches higher than the 63 degree average over the last 30 years.

Those may not seem like big leaps, but even a few degrees of higher-than-average temperatures means there has to be a string of very warm days.

So what’s the reason behind the warmer temps?

There isn’t a lot of cold air coming in from Canada. There also hasn’t been any wild weather pattern changes; when drastic changes don't occur, the temperatures trend toward normal or warmer, Pastelok said.

Climate change may be a factor too, he noted.
