A weather system originating in Siberia is predicted to cause a major drop in temperatures across the entire country.

The season’s first Arctic outbreak is on track to move through the US during Thanksgiving, delivering freezing conditions and possibly some snow.

An Arctic air blast originating from Siberia is set to bring the first significant cold wave of the season during the final week of November 2024. Weather Track US posted on X, noting that the incoming Arctic air mass is expected to drive temperatures down by as much as 25°F below the seasonal norm in certain regions.

A large portion of the continental US will experience temperatures dropping at least 10°F below average, promising a notably colder Thanksgiving holiday.

We’re in for a very significant blast of Arctic/Siberian air later this week and into early December.

This airmass will drop temps up to 25°F below average in some areas, but most of the CONUS will be at least 10°F below average.

While cold temperatures are predicted to reach southern regions, such as the Gulf Coast and portions of the Southwest, regions near the Great Lakes and the Northeast should brace for snowfall.

As stated on X, “Dangerous wind chills across the Upper Midwest and heavy snows downwind of the Great Lakes will accompany this wintry blast.” The National Weather Services affirmed these information.

Outbreaks in the Arctic can have serious and far-reaching effects. Unprotected pipes may freeze and rupture due to these extreme cold air masses, resulting in expensive water damage. Large fish kills frequently occur in shallow estuaries as a result of the abrupt temperature change.

Significant losses can occur in agriculture, especially for seasonal crops like strawberries, citrus trees, and tropical plants.

Furthermore, structural fires may result from the incorrect usage of heating equipment during these cold spells. There is also a significant risk of carbon monoxide poisoning from fuel-based heaters with inadequate ventilation.

In addition, Arctic outbreaks can have an economic impact comparable to a Category One hurricane in regions such as the Gulf Coast, impacting ecosystems, livelihoods, and infrastructure.
