Brace for a Chilly December: Polar Vortex Brings Triple Trouble

The central and eastern U.S. is bracing for a frosty December, courtesy of a shifting polar vortex. This weather pattern is set to deliver three rounds of Arctic air, starting this week.

First Wave Hits Midwest

The initial cold snap is already impacting the Midwest, with temperatures plummeting significantly. By Friday, the cold front will spread to the Northeast and mid-Atlantic regions.

Two More Blasts of Frigid Air Expected

Meteorologists predict two additional cold outbreaks in the coming weeks. The polar vortex—a large area of low pressure and cold air around the Earth's poles—is expanding, allowing Arctic air to move southward along the jet stream.

Second cold outbreak: Expected next week
Third round: Likely in the middle of the month

Record-Low Temperatures Forecasted

Temperatures are expected to plummet, challenging daily record lows in some areas:

Midwest: Lows in the negative single digits and teens
Northern Mid-Atlantic & New England: Single digits and teens
Interstate 95 Northeast Corridor: Temperatures dropping into the 10s and 20s
Dakotas to Nebraska: Subzero temperatures expected

Safety Tips for the Cold Snap

To stay safe during this extreme cold:

Winterize Your Home

Have your heating systems checked
Avoid using generators, grills, or camp stoves indoors to prevent carbon monoxide poisoning
Never use your oven or stove to heat your home
Use battery-powered lanterns or flashlights to avoid fire risks
Close off unused rooms
Exercise caution with fireplaces and space heaters

Dress Warmly for Outdoor Exposure

Wear layers of loose-fitting, warm clothing
Use a hat, mittens, and a scarf or ski mask to cover your face
Wear water-resistant boots to keep feet dry
Avoid overexertion, as it can lead to serious medical conditions
