AccuWeather fall forecast

As the fall season gets underway, warm weather is set to continue across the Northeast and mid-Atlantic.

In the Southeast, residents will need to remain on alert for tropical impacts, while the southern Plains braces for a second severe weather season.

Meanwhile, Santa Ana winds will threaten to bolster the fire threat across Central and Southern California.

Above-normal warmth to continue across much of the Northwest

Across much of the Northwest, above-normal temperatures will continue into the fall season.

The Pacific Northwest to east of the Cascades will get the worst of the heat and dryness, AccuWeather Expert Long-Range Forecaster Paul Pastelok said, particularly in the beginning of the season.

This will add to the wildfire risk for these regions.

“But farther east, across parts of Montana and Wyoming, I think they could get some moisture and a cooldown,” he added.

The conditions will limit the vibrancy of the fall foliage in these areas, leading to a “spotty” season at best.

Late into the fall, the return of a more active storm track may promote heavy rain and even snow in drier parts of the Golden State.

Warm weather to continue in the Northeast and mid-Atlantic

After several rounds of heat this summer, warm weather is predicted to stick around across much of the Northeast and mid-Atlantic this September.

Southeast and the Gulf States to remain at risk for tropical impacts

The Southeast and Gulf states will remain on alert for a tropical impact into the autumn, with forecasters predicting as many as two to three more impacts for the United States.

Active weather pattern in store for the southern Plains

A generally active weather pattern is in store for the southern Plains this autumn.

“We are calling for near-normal number of severe weather events for the late-severe weather season, but it may be most active along the Gulf coast and central Plains during the period,” Pastelok said.

4 cities will feel summer warmth into autumn

It may feel like an endless summer for parts of the United States this year, as fall, well, falls back and higher-than-normal temperatures linger longer.

Much of the Northeast and the mid-Atlantic I-95 corridor can expect to have temperatures 3 to 3.5 degrees above normal this September. Also, for much of the Northwest above-normal warmth will continue deeper into fall, according to AccuWeather meteorologists.

Spokane, (3.5 degrees above normal), Portland, Ore. (2.5), Baltimore, Md. (1.5-2), and Washington, D.C., (1.5-2) are four U.S. cities expected to feel the extended summer warmth. Baltimore and Washington, D.C., averaged temperatures 1.5 to 2 degrees above normal last fall also, while Portland was 1 degree above normal and Spokane was around its average temperature.

“Like the past few seasons, the East will enjoy late-summer weather and vacations at the beaches,” said AccuWeather Lead Long-Range Meteorologist Paul Pastelok. “And the Pacific Northwest to east of the Cascades will get the worst of the heat and dryness, particularly in the beginning of the season.”

It is worth noting that the averages and stats above are from meteorological fall (Sept. 1 - Nov. 30) as opposed to Sept. 23 - Dec 21.
