The first Arctic outbreak of the season is set to sweep across the US during Thanksgiving, bringing freezing temperatures and potential snowfall.
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.”
Arctic outbreaks can have widespread and severe consequences. These intense cold air masses may cause unprotected pipes to freeze and burst, leading to costly water damage. Shallow estuaries often experience large fish kills due to the sudden drop in temperatures.
