September could start with thunderstorms in the northeast and southeast, while the Midwest and western U.S. could enjoy clearer conditions.
The Atlantic Seaboard could also experience “a notable hurricane threat,” and thunderstorms and tornado activity could be in store for central states, especially in the Ohio Valley and the Plains.
Moving into October, parts of the northeast and Great Lakes regions could see early snow.
“Stormy interludes return mid-month, bringing rain and gusty winds across much of the country,” the almanac’s summary says.
In terms of rain, the wettest regions of the country this fall will be the Great Lakes, Northeast, and parts of the Southeast, while the Southwest and West Coast are expected to have dry stretches.
November, according to the almanac, is when many Americans will see the first true signs of winter.
“Snow becomes more frequent in the Rockies, Plains, and Great Lakes, with wet snow even reaching parts of the Northeast,” it says. “The Southeast sees a mix of rain and clearing skies, while the Southwest and Northwest experience unsettled conditions with mountain snow.”
