Major Cold Blast Expected Across U.S. During Thanksgiving Week: Temperatures Could Plummet Nationwide

UNITED STATES — Meteorologists are tracking a major Arctic cold blast expected to sweep across the United States during Thanksgiving week, bringing the coldest air of the season so far and a dramatic shift in temperatures nationwide.

According to long-range model guidance analyzed by POW Ponder on Weather, the setup could unfold shortly after midweek next week, as teleconnection patterns — large-scale atmospheric signals — align to pull frigid air southward from Canada.

“This pattern looks like a strong early winter setup,” meteorologists said. “Once the Arctic air breaks loose, it could cover a massive portion of the country by Thanksgiving week.”

Big Temperature Drop Expected Nationwide

Forecast maps show a deep trough forming over the central U.S., with below-average temperatures spreading eastward just in time for the holiday travel rush. Areas in the Midwest, Great Plains, and interior Northeast are likely to experience the most significant drop, while colder air will eventually reach parts of the South and East Coast.

The Great Lakes region and Upper Midwest may see daytime highs plunge into the 20s and 30s, while overnight lows could dip into the teens. Even southern states like Texas, Louisiana, and Georgia could feel a sharp chill by Thanksgiving Day.

“This is shaping up to be the biggest cold snap we’ve seen in five years,” said forecasters monitoring the system. “It’s a major temperature swing that could catch some early travelers off guard.”

Unsettled Weather Pattern Ahead

Along with the cold air, forecasters are warning of unsettled conditions leading up to the Thanksgiving holiday. A storm system developing in the middle of the country could bring rain, snow, or mixed precipitation, depending on location.

Early indicators suggest:

• Rain and wind along parts of the East Coast
• Snow potential across the northern Plains and upper Midwest
• Cold rain or wintry mix possible in parts of the central U.S.

Meteorologists stress that while exact timing and storm tracks could still change, the overall signal points to a dramatic nationwide cooldown beginning around November 20–22 and lasting through Thanksgiving weekend.

Travel Impacts Likely for Thanksgiving Week

With one of the busiest travel periods of the year approaching, the timing of the cold blast could cause flight delays, hazardous driving conditions, and increased travel demand around storm-affected areas.

“Anyone flying or driving the week of Thanksgiving should monitor forecasts closely,” weather experts advised. “If you’re traveling across the Midwest or Northeast, prepare for possible snow or icy roads, especially late next week.”

Prepare for the Cold Ahead

Residents are urged to check heating systems, bring in outdoor pets and plants, and prepare winter gear as the first strong Arctic air mass of the season takes hold.

“This cold wave is a reminder that winter is knocking early this year,” forecasters said. “Expect a true chill across much of the nation by Thanksgiving.”
