We’re getting ready to release our 2020-21 winter weather forecast, (get the forecast now, order a copy of the 2021 edition), but you may be wondering, “what’s in store for fall?”

The new season officially starts on Tuesday, September 22, 2020, at 9:21 a.m. EDT with the arrival of the Autumnal Equinox. After a scorching summer for many areas, cooler temperatures will be a welcome relief. So, when will this fall deliver some “sweater weather”? Here’s what we’re predicting.

2020 Fall Forecast Overview

The 2020 Farmers’ Almanac indicates that fall will transition with cooler temperatures slowly moving in during September in all regions. The East will see a cool, dry September and October, with colder and stormier conditions expected for November and December.

Over the Plains, possibly extending as far east as the Ohio Valley, there may be outbursts of severe weather capable of spawning a few tornadoes during September.

The rest of the fall season will see successive pushes of stormy, progressively colder air masses.

The far West will see alternating periods of fair and unsettled weather in September, but as we progress further into October and especially November, we’ll see storm activity from the Pacific increasing, bringing windy and rainy conditions as we approach the end of the year.

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. 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.”

Most of the New England states—where many will be making the trek to view fall foliage— are experiencing moderate to severe drought conditions, which may affect the vibrancy of colors.

You can check the current drought map to see if your area is experiencing drought.

Will We See Snow Fall In Fall?

Before winter officially arrives on December 21st, we’re predicting that many of our weather zones will see some light wintry precipitation before then. In fact, our first mention of flurries comes during the beginning of October over the northern Rockies.

Whatever your plans are for Thanksgiving this year, you’ll want to know the weather so you’ll be prepared.

Tropical Storms

According to the 2020 Canadian Farmers’ Almanac, we anticipate tropical activity will ramp up in mid-September with a hurricane threat for the Maritimes. Another potential hurricane could take a swipe at Cape Race to the Avalon Peninsula a week later. Typically, tropical cyclone activity over the Atlantic and Caribbean Sea increases exponentially during the second week of August and reaches its traditional peak on September 10.

Will Your Thanksgiving Be Squashed?

Thanksgiving is Monday, October 12th. Overall, conditions look promising with pleasant weather for most of Canada, except for zones 4 and 5, which could see wet weather.

Will Snow Fall In Fall?

This year’s fall forecast proves it doesn’t have to officially be winter for it to snow! The first mention of wet snow comes during the final week of October over Ontario and points east. The far West will see alternating periods of fair and unsettled weather in September. As we progress into October and November, we’ll see storm activity from the Pacific on the increase bringing bouts of windy and rainy conditions as the end of the year approaches.
