Winter Weather Forecast For Sudbury: See Daily Prediction

SUDBURY, MA — With the official start of the 2021-22 winter a little more than two months away, some Sudbury residents may be eager for the colder weather to arrive to plan some exciting, wintry fun.

Specific, long-term weather predictions can help with planning outdoor activities best suited for the cooler temps. To help you plan ahead, the private weather company AccuWeather has released its 2021 winter weather forecast.

Daily forecasts for Sudbury are listed through the end of December. After that, AccuWeather lists the historical average temperature for the rest of the winter. The weather looks pretty pleasant through October with temperatures in the 60s and mostly dry. The first snow may not come until just before Thanksgiving, according to the very long-range forecast.

Nationally, AccuWeather predicts an eventful winter similar to the 2020-21 season, which brought record-breaking snowfall and blackouts to some parts of the country.

Meteorologists also expect the return of La Niña, a weather phenomenon that occurs when the water near the equator of the Pacific Ocean is cooler than average. It will shape part of the overall weather patterns this winter, weather experts said.

The upcoming La Niña will be weaker than the one experienced last winter, in turn, opening up the door for other elements to factor into the winter forecast — especially during the second half of the season.

This year, the polar vortex may also be weaker, according to AccuWeather. This could result in colder air from the Arctic to slide southward into the U.S. before the official start of meteorological winter, which is on Dec. 1. The first official astronomical day of winter arrives on Tuesday, Dec. 21.

Winter could pound the Northeast with a vengeance starting in mid-December before potentially intensifying in January, which could include a heightened risk for nor'easters and, yes, snowstorms at the tail end of the season.
