Fall officially begins this week (Wednesday, September 22, at 11:09 p.m., (EDT) for those of you keeping score at home). After a summer of sizzling heat throughout most of the U.S. and Canada (sorry, West Coast), the cool-down that accompanies autumn will be a welcome relief to some and a source of sadness for others. So what’s in store for the coming months?
The closing weeks of September should bring cooler, but still pleasant, temperatures in most regions. Moving into October, seasonable temperatures and precipitation are predicted, with pockets of clear, warm weather sandwiched between frequent rain showers.
We’re calling for snow over Montana in the opening days of October. More early snow could fall over parts of the Rockies toward the middle of the month. For Halloween, the weather should be a treat in most regions, with the exception of the Northeast and Pacific Northwest, where Mother Nature is expected to scare up a storm.
As fall deepens, November will bring wet, chilly weather, with the possibility of early snowfall for the Northeast and Great Lakes in the opening days of the month. Once the snow starts, it will continue throughout much of the rest of the month and into December.
Elsewhere, look for fairer, more pleasant conditions through much of November, punctuated by occasional cold, blustery periods. Expect snowfall in the Rockies toward the middle of the month, with a possibility of heavy accumulation.
Over the Thanksgiving holiday, light snow could fall in most regions, except the Southeast Coast and Pacific Northwest, where rainy, unsettled conditions will prevail.
In the opening days of December, snow will continue to fall over much of the nation, bringing wintry conditions well before the official start of the season. Only the West Coast and South Central region will see dryer, warmer weather through much of the first half of the month.
