The 2021 edition of the Farmers’ Almanac went on sale Monday.

Based on a “carefully guarded formula” that’s been followed for 204 years, the almanac this year forewarns areas from the Great Lakes and the Midwest westward through the Northern and Central Plains and Rockies that they are in for a cold winter, with normal to below-normal temperatures.

Snow will be abundant, the almanac says, with possibly above-normal amounts for parts of the western Dakotas, northern portions of Colorado and Utah, as well as Wyoming, which is great news for skiers.

The Mid-Atlantic region is expected to be “seasonably cold, wet and white,” capped by a February blizzard.

The almanac notes that the “winter wild card” for winter 2020-21 “belongs to areas around the Tennessee and lower Ohio River valleys, north and east up through New England … which will see a mix of intense weather systems that will keep delivering a wintry mix of rainy, icy and/or snowy weather throughout the season.”

And then during the second week of February, the almanac forecasts “a blizzard bringing 1-2 feet of snow along the eastern seaboard."

“If you didn’t like last winter’s somewhat-boring weather in the Northeast,” said managing editor Sandi Duncan, “you may be happy to hear what we are predicting for 2021.”

According to the almanac:

The southeastern part of the country, excluding the Tennessee Valley, will experience average precipitation levels, with temperatures chillier than normal.

In areas across the desert Southwest (Arizona and southern California), winter is predicted to be mild but dry.

In New Mexico, Texas, Oklahoma and east into Arkansas and Louisiana, Mother Nature will mix intervals of tranquil weather with occasional shots of cold and wintry precipitation.

Along the Pacific Coastal Plain, from northern California and points north through western portions of Oregon and Washington, rainy and wet weather will be the rule for the winter ahead.

“Preparing people for the unexpected is more important than ever,” said editor Peter Geiger. “Our job as editors of the Farmers’ Almanac is to pass down valuable tips and advice to help our readers thrive, no matter the obstacles, including the weather.”

In addition to the winter outlook, the 2021 edition of the Farmers’ Almanac contains advice on ways to grow your own food, raise chickens, save money, boost your immunity, go fishing, and plant a prolific garden.
