New York, Pennsylvania, New Jersey, and New England Forecast to See Dangerous Subzero Temperatures on Christmas, New Euro Model Shows

NEW YORK — New Christmas Day projections from the European weather model now indicate dangerously cold temperatures across New York, Pennsylvania, New Jersey, and the New England states, confirming that an intense Arctic air mass will dominate the region through the holiday.

Euro Model Confirms Deep Freeze Instead of Expected Warmup

The latest 12z Euro run reverses all earlier hints of a December warm spell. Instead, the model now shows a powerful cold surge gripping the Northeast, delivering Christmas morning temperatures far below normal.

Meteorologists say the update removes any doubt of a “torch” pattern and instead highlights a stronger, more sustained cold outbreak across the region.

Subzero Temperatures Expected Across the Northern Northeast

According to the updated Euro temperature projections:

• Northern New York, Vermont, New Hampshire, and Maine may see Christmas morning lows between -5°F and -15°F
• Upstate Pennsylvania and interior New England could fall into the single digits
• Major metro areas — including New York City, Philadelphia, Newark, and Boston — are expected to remain in the teens to low 20s, still sharply below seasonal averages

These conditions confirm that winter has no intention of loosening its grip, despite earlier model runs suggesting a brief warm phase.

Warm Pattern Rejected After Days of Uncertainty

Forecasters compared the shifting model signals to a running storyline — hinting at relief but always ending the same way. Today’s Euro run ends all speculation by firmly locking in a cold, winter-dominant pattern for December 25.

Meteorologists now say confidence is high that the region will experience a true Arctic Christmas, not a mild holiday.

Cold Could Affect Holiday Travelers Across the Northeast

Though no significant snowstorm is currently indicated, the severe cold could still impact Christmas travel. Wind chills, icy patches, and increased heating demand are all concerns heading into the holiday weekend.

Travelers driving into northern or inland areas of New York and New England should monitor conditions closely.

Winter Weather Pattern Strengthens Across the Northeast

With multiple forecast models now aligning, the message is clear: New York, Pennsylvania, New Jersey, and all of New England are heading toward a bitterly cold Christmas, and any expectations of a warm holiday period have officially ended.
