Statewide Freeze Warning as Temperatures Drop Toward Record Cold After Recent Warm Spell
New Jersey is experiencing a dramatic shift in weather conditions as a strong cold air mass moves into the region, bringing the risk of near-record low temperatures across much of the state. This comes just days after parts of the state saw unusually warm conditions reaching the 90s, highlighting a sharp and rapid temperature change.
According to the National Weather Service, a freeze warning has been issued for most of New Jersey from midnight until 9 a.m. Tuesday. The warning covers all 21 counties, although some coastal areas near the Jersey Shore may see slightly milder conditions compared to inland regions.
Forecasters expect temperatures to drop significantly overnight, with some areas in northwestern New Jersey potentially falling to around 22 degrees. Many other parts of the state are likely to see lows in the low to mid-20s, conditions that are unusually cold for late April. These temperatures are close to or even below historical records for this time of year.
In Newark, the record low for April 21 stands at 31 degrees, set back in 1981, and forecasters say this record could be challenged or broken depending on how far temperatures fall overnight.
Throughout Monday, daytime conditions will remain colder than normal, with highs only reaching the mid-40s to mid-50s. This is well below the seasonal average for late April in New Jersey. Some light showers may develop during the day, especially in areas southeast of the I-95 corridor. Meteorologists also noted the possibility of graupel mixing in with precipitation in isolated spots due to cold air higher in the atmosphere.
As the cold air begins to move out, temperatures are expected to slowly recover on Tuesday. Morning hours will still be very cold, but conditions should gradually improve through the day, with highs reaching the mid to upper 50s.
A more noticeable warming trend is expected midweek. By Wednesday, temperatures across much of New Jersey are forecast to rise into the mid to upper 60s, offering a return to more seasonal conditions. Thursday is currently expected to be the warmest day of the week, with temperatures climbing into the 70s in many areas.
However, the warming trend may not last long. Forecasts indicate another cooling pattern could begin by Friday, particularly along coastal areas. A developing weather system may bring scattered showers from Friday into Saturday, and a larger storm system could potentially impact the region by Sunday. At this time, meteorologists say there is still uncertainty regarding the exact timing and strength of that system.
The rapid temperature swings seen this week reflect the changing spring weather pattern, where warm and cold air masses can move in quickly, leading to unstable and sometimes extreme conditions.
