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.Regions near the Great Lakes and the Northeast should prepare for snow, while freezing temperatures are likely to reach southern areas, including the Gulf Coast and parts of the Southwest.

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.”
