A prolonged and dangerous stretch of arctic cold is firmly in place across much of the eastern United States and is expected to continue into early February, according to the latest outlook from the Weather Prediction Center and Climate Prediction Center.

The cold air mass has already delivered record and near-record low temperatures across large portions of the South and Midwest in the wake of a recent winter storm. Overnight lows have plunged into the single digits and below zero in many areas, creating life-threatening conditions, especially for those still dealing with power outages or inadequate heating.

Wind chills are compounding the danger. In parts of the Ohio Valley, wind chills are forecast to drop into the minus 20s, posing a serious risk of frostbite and hypothermia even with limited exposure. Officials urge residents to limit time outdoors, dress in multiple layers, and ensure pets and livestock have adequate shelter from the cold. Frozen pipes also remain a major concern as temperatures stay well below freezing for extended periods.

The accompanying temperature outlook map shows that areas north of the highlighted pink line are expected to remain continuously below freezing through at least February 1. This includes much of the Midwest, Great Lakes, Northeast, and interior Mid-Atlantic, where daytime highs may struggle to rise above the teens and 20s.

Relief will be limited, as another surge of arctic air is expected to move southward late this week. Forecast guidance indicates a renewed blast of bitter cold spreading from the Plains into the East and Southeast Friday into Saturday. This surge could bring additional record low temperatures, potentially reaching as far south as Florida, and may mark the coldest conditions seen in several years for some locations.

Forecasters also warn that this could become one of the longest-lasting cold stretches in decades for parts of the eastern half of the country. Much below normal temperatures are expected to persist into the middle of next week before a gradual moderation begins.

With the extended duration of the cold, residents are encouraged to take ongoing precautions. This includes checking on vulnerable neighbors, using space heaters safely, keeping a slow drip on indoor plumbing, and having emergency supplies readily available.
