Bitter Cold Pattern Taking Shape Across the Eastern U.S. Over the Next Two Weeks

A prolonged stretch of colder than normal temperatures is becoming increasingly likely across much of the eastern United States as we move deeper into late January. The latest temperature outlooks from the Climate Prediction Center show a strong and persistent signal for below average temperatures developing during both the 6–10 day and 8–14 day forecast periods.

The 6–10 day outlook highlights a broad area of colder than normal conditions expanding from the Midwest into the Ohio Valley, Mid-Atlantic, and Northeast. The highest confidence for below normal temperatures is centered over the Great Lakes and interior Northeast, where probabilities strongly favor temperatures well below seasonal averages. This colder air mass is expected to gradually spread eastward and southward as the pattern evolves.

By the 8–14 day timeframe, the cold signal strengthens and becomes more entrenched across the eastern half of the country. Much of the Mid-Atlantic, Southeast, and Northeast show a high likelihood of sustained below normal temperatures, indicating that this will not be a brief cold snap. Instead, forecast guidance suggests repeated intrusions of Arctic air reinforcing the cold pattern well into early February.

Meteorologically, this setup is driven by a strong ridge of high pressure over the western United States and a deep trough anchored across the eastern U.S. This configuration allows cold air from Canada to repeatedly spill southward, keeping temperatures suppressed for an extended period. While the western U.S. remains warmer than average under the ridge, the eastern states remain locked in a colder regime.

For residents across the Mid-Atlantic and Northeast, this pattern could bring multiple days of daytime highs running well below normal, along with colder overnight lows. The persistence of the cold also raises the potential for increased energy demand, frozen pipes, and heightened vulnerability for those without adequate heating. Any storm systems that develop during this period would also need to be closely monitored, as the presence of cold air could support winter weather threats.

Forecast confidence is increasing that this cold stretch will be one of the more significant and long-lasting cold periods of the season for the eastern United States. Residents are encouraged to prepare for prolonged winter conditions and stay updated as forecasts are refined in the coming days.
