2021 Fall Forecast Overview

The Farmers’ Almanac extended forecast for fall indicates that things will transition from rather warm and humid conditions in September to an unusually agitated and turbulent month of October. October for much of the country is usually the clearest and most tranquil month of the year.

There is an old saying in New England, for instance, that October usually has 19 fair days. That might normally be true, but 2021 will be the exception—not the rule—with quite a few cloudy, windy, and showery days. That will set the stage for November, which will only be an extension of October’s unsettled weather pattern, except it will be turning colder with some snowflakes predicted.

Watch for some snow to enter the picture, especially over higher terrain areas. (Check out your forecasts here.)

What’s The Prediction For Fall Foliage?

We’ve all been gradually losing daylight since the summer solstice, and this is Mother Nature’s cue to begin the process of the changing of colors of deciduous tree leaves. Weather plays a role in the intensity of fall foliage colors. “Drought is the enemy of a good fall,” says biology professor Howard Neufeld of Appalachian State University in North Carolina. “The trees have to be in a healthy state, not water-stressed, heading into the season.”

In New England—where many will be making the trek to view fall foliage— many parts of Maine and Northern New Hampshire are experiencing abnormally dry conditions, which may affect the vibrancy of colors.

Will We See Snowfall In Fall?

Before winter officially arrives on December 21st, at 10:59 a.m. EST, we’re predicting that a few of our weather zones will see some light wintry precipitation in mid-November and early December. In fact, our first mention of “wet snow” comes in October in the Northeast and Great Lakes zones!
