A blast of Arctic air from Siberia will mark the first major cold snap of the season starting this last week of November 2024. Weather Track US shared on X that forecasts show approaching Arctic air mass will cause temperatures to plummet as much as 25°F below seasonal averages in some areas.
Most of the continental US will see temperatures at least 10°F lower than usual, making for a chilly Thanksgiving holiday.
The National Weather Services confirmed these details, writing on X, “Dangerous wind chills across the Upper Midwest and heavy snows downwind of the Great Lakes will accompany this wintry blast.”
Agriculture can suffer significant losses, particularly for citrus trees, tropical plants, and seasonal crops like strawberries.

Additionally, the improper use of heating devices during these cold spells can lead to structural fires. Inadequate ventilation of fuel-based heaters also poses a serious risk of carbon monoxide poisoning.
Furthermore, the economic impact of Arctic outbreaks in areas like the Gulf Coast can rival that of a Category One hurricane, affecting infrastructure, livelihoods, and ecosystems.

Therefore, the National Weather Service Southern Region advised having multiple means of receiving weather alerts during the Arctic outbreak, which is expected to last through Monday, December 2, 2024.
They also suggested carrying a NOAA weather radio alongside Thanksgiving preparations to ensure everyone stays informed about potential weather hazards.
On November 29 and 30, travel may be affected due to snowfall across certain parts of the Central US. Post-Thanksgiving travelmay also be affected due to the Arctic cold break in some areas of the Central and Southern US. The heavy lake effect snowdownwind of the Great Lakes could also affect traveling after Thanksgiving.
Other specifics shared on the map are that Missouri will experience hazardous cold from November 30 to December 4. On the same dates, Houston will experience frost and freeze while Detroit will have heavy snow.
In these states, rain combined with locally dense fog is expected to create wet roads and reduced visibility, heightening the risk of delays and accidents. The situation is further compounded by increased holiday traffic, making caution and preparedness essential for safe travel.

Stacey Barber, the Vice President of the American Automobile Association (AAA) has said, “Thanksgiving is the busiest holiday for travel, and this year we’re expecting to set new records across the board, from driving to flying and cruising.
AAA estimates that approximately 79.9 million people will travel 50 miles or more from their homes during the Thanksgiving holiday period.
