Polar Vortex Threatens Travel Disruptions for Thanksgiving Holiday

A polar vortex is poised to bring unseasonably cold temperatures to the Midwest and Northeast United States during the Thanksgiving holiday period, potentially disrupting travel plans for millions. The National Weather Service forecasts below-normal temperatures in these regions from November 25 through November 30, 2025. This weather event coincides with a record 81.8 million Americans projected to travel at least 50 miles between November 25 and December 1, according to the American Automobile Association (AAA).

A polar vortex is a large area of low pressure and cold air surrounding the Earth's poles. During winter, the polar vortex can expand, sending cold air southward into the United States, leading to significant drops in temperature. This phenomenon can result in severe winter weather conditions, including snowstorms and icy roads, which can disrupt travel and daily activities.

The National Weather Service has issued forecasts indicating below-normal temperatures in the Midwest and Northeast United States from November 25 through November 30, 2025. Major cities such as Chicago, New York City, and Boston are expected to experience significant temperature drops. This period coincides with the Thanksgiving holiday travel season, during which a record 81.8 million Americans are projected to travel at least 50 miles between November 25 and December 1, according to the American Automobile Association (AAA). Of these travelers, approximately 6 million are expected to fly domestically.

The combination of increased travel volume and adverse weather conditions poses a risk of significant disruptions:

• Air Travel: Airports in affected regions may experience delays or cancellations due to de-icing requirements, reduced visibility, and runway conditions. Travelers are advised to check with airlines for real-time updates and consider flexible travel plans.

• Road Travel: Icy and snowy conditions can lead to hazardous driving situations, increasing the likelihood of accidents and road closures. Motorists should exercise caution, plan for longer travel times, and stay informed about road conditions through local transportation departments.

Polar vortex events have previously impacted the United States, notably in January 2014 and January 2019, leading to record-low temperatures and widespread travel disruptions. The 2014 event resulted in over 4,000 flight cancellations and numerous road closures. The current forecasted event's timing during the Thanksgiving holiday travel period adds a unique challenge, as it coincides with one of the busiest travel times of the year.

To mitigate potential delays and disruptions, travelers are advised to:

• Stay Informed: Regularly monitor weather forecasts and travel advisories from the National Weather Service and local authorities.

• Plan Ahead: Allow extra time for travel, consider alternative routes, and have contingency plans in place.

• Safety Measures: Ensure vehicles are winter-ready, carry emergency kits, and dress appropriately for cold weather conditions.

By taking these precautions, travelers can better navigate the challenges posed by the polar vortex during the Thanksgiving holiday period.
