Arctic Blast to Hit U.S. as Polar Vortex Starts 2025 — When to Expect It and How Long It Will Last

The United States is gearing up for a frigid start to the new year, as Arctic air, propelled by a polar vortex originating in Siberia, is set to envelop the country. The Washington Post reports that this icy air mass is anticipated to make its arrival on Monday night and gradually spread to the East Coast by Wednesday.

What is the polar vortex and its impact?

The polar vortex is a phenomenon characterized by a blast of cold air that is usually restricted to the North Pole. However, on rare occasions, this extremely cold system moves southward, resulting in bone-chilling temperatures across the United States. This year, experts are predicting a third surge of Arctic air, making the impact of the polar vortex even more significant.

When and where to expect arctic blasts

Early this week, the Arctic air is expected to make its first entrance, followed by another wave later in the week. By next week, a third surge of cold air will sweep across the Midwest and the Eastern Seaboard, causing temperatures to plummet to subzero levels in over 30 states.

Snowfall predictions and affected areas

While there won’t be widespread snowfall, there is a chance of significant snow accumulation in regions near Lakes Ontario and Erie. Specifically, areas like the Tug Hill Plateau and south of Buffalo are expected to experience heavy lake-effect snow. This occurs when the cold air interacts with the relatively warmer waters of the lakes.

How long will the cold spell last?

Get ready to stay warm for an extended period as meteorologists are forecasting that the Arctic chill will persist throughout the first three weeks of January. Although the Eastern region will face the harshest conditions, below-average temperatures are also expected in the West and Alaska.

The Polar Vortex is expected to arrive in the United States in 2025, bringing with it an Arctic blast that will impact the country. It is important to know when to expect this weather phenomenon and how long it will last. According to reports, the Polar Vortex is set to hit the U.S. in the near future, causing frigid temperatures and potentially dangerous conditions. It is crucial for individuals to stay updated on weather forecasts and take necessary precautions to ensure their safety during this time.
