Philadelphia, Pennsylvania – A renewed push of colder air is settling back into the Mid-Atlantic, pulling Pennsylvania and New Jersey into a below-normal temperature pattern after a brief period of moderation earlier this month.
According to the National Weather Service and NOAA’s Climate Prediction Center, temperatures across the Mid-Atlantic are now favored to run below seasonal averages, with the shift becoming increasingly noticeable across Pennsylvania and New Jersey. Daytime highs are expected to trend lower, while overnight cold strengthens across both states.
In Pennsylvania, colder air will be felt statewide. Philadelphia and the surrounding suburbs are expected to see highs mainly in the upper 20s to low 30s, while central and northern Pennsylvania drop back into more persistent winter cold. Overnight lows in the teens will be common, with single digits possible in rural and higher elevation areas.
New Jersey follows a similar pattern, with colder conditions spreading from northwest to southeast. Areas from the Poconos and northwest New Jersey into the I-95 corridor, including Newark and Trenton, are expected to remain below normal, with highs near or just above freezing and teens overnight. Coastal areas may hold slightly milder afternoons but will still trend colder than seasonal norms.
While widespread precipitation is not a primary concern at this time, colder temperatures raise the risk of refreezing and black ice, particularly during overnight and early morning hours. Travel along major routes including I-76, I-80, I-78, the New Jersey Turnpike, and I-95 may be impacted during colder periods.
Residents across the Mid-Atlantic are urged to prepare for a renewed stretch of winter conditions by protecting pipes, using caution during commutes, and limiting prolonged exposure to the cold. This pattern does not indicate extreme Arctic air, but it does signal a return to sustained winter chill. Additional alerts or advisories may follow as February continues to unfold.
