Residents of New Jersey should prepare for an extended period of intense cold. Meteorologists indicate that the current Arctic blast may persist for at least another week. Early December temperatures resemble mid-winter conditions, affecting not just New Jersey but also much of the Northeastern United States.
Forecast Highlights for New Jersey’s Cold Snap
The forecast suggests that while not every day will be exceptionally cold, daily temperatures will remain below the seasonal average. During the first week of December, temperatures have been recorded at 6 to 8 degrees Fahrenheit lower than normal.
Temperature Averages
- Newark Liberty International Airport: 34.6°F (normal: 41.2°F)
- Atlantic City: 35.4°F (normal: 41.5°F)
- Trenton: 32°F (normal: 40°F)
On December 8, temperatures are predicted to be 16 to 17 degrees below the seasonal average. Most areas will experience daytime highs around 29°F to 30°F, with overnight lows expected to dip into the low to mid-teens, ranging from 16 to 18 degrees below typical early December temperatures.
Causes of the Cold Weather
This severe cold snap is attributed to a weakened polar vortex. Under normal circumstances, a strong polar vortex confines frigid air to the north. However, when the vortex weakens, it allows icy air to push down into the central and southern United States.
Potential Snow Events
In addition to the cold temperatures, New Jersey may experience two light snow events this week:
- First System: Expected on Wednesday, potentially bringing 1 to 2 inches of snow to higher elevations.
- Second System: Possible light snow from Friday night into Saturday morning, but forecasts remain uncertain.
Meteorologists will provide updates as new data emerges regarding the second storm system. Residents are advised to stay apprised of changing weather conditions and prepare accordingly.
