Strong winds, low temperatures, and a possibility of heavy snowfall might affect many American families as they come together for Thanksgiving celebrations next week.

Weather experts have warned of “unsettled weather” affecting a large portion of the country due to a low-pressure system in the mid-levels of the atmosphere, potentially extending into the busy travel period after Thanksgiving.

Many regions could experience “the coldest air of the season,” as stated by the National Weather Service.

Here’s what the weather looks like for Thanksgiving:

Rain and snow expected in the East on Thanksgiving and Black Friday

A developing storm might bring a wintry holiday to the eastern United States, according to meteorologists from AccuWeather.

If the storm progresses slowly, it might significantly affect travel from the Tennessee and Ohio valleys up to the Northeast. Conversely, if it moves further south and off the Carolina coast, it could be less severe but still result in rain and snow.

“This storm could disrupt travel for those moving around in parts of the Midwest and Northeast on Thanksgiving,” noted AccuWeather Senior Meteorologist Tyler Roys. “Even those seeking Black Friday deals might face some travel difficulties.”

The weather could also pose challenges for popular holiday parades, particularly in New York City, as reported by AccuWeather.

The National Weather Service has indicated a moderate risk of “hazardous cold” conditions in the Northern Plains, with temperatures possibly dropping as low as -10 degrees, feeling even colder due to the wind chill. There’s also a slight chance of significant snow across the Great Lakes and the Northeast.

Strong winds are expected to impact much of the eastern US from Wednesday to Friday, especially in southern areas away from the coast, as well as in the central Appalachians and mid-Atlantic regions, according to the weather service.
