Enjoy the warmth while it lasts. By Thursday, the windows will be shut, the jackets will be back, and winter will remind New Jersey who is still in charge.
For a few dazzling days, it felt like winter had packed up and left early. New Jerseyans shed their coats, threw open the windows and got a cruel taste of May in March.
New Jersey is experiencing a record-breaking warm spell in March 2026, with temperatures soaring into the 70s and 80s, fueled by a high-pressure system acting as a heat pump.
Several locations, including Sussex and Walpack, tied or broke previous daily records around March 10-11, bringing a “false spring” to the region.
But as any longtime resident could have predicted, the atmospheric tease was temporary. The balmy weather that shattered records across the state is on its deathbed, done in by a collision of air masses and a stubborn polar vortex that refuses to relinquish its grip.
The numbers turned heads. On Tuesday, the thermometer at Newark Liberty International Airport hit 82 degrees Fahrenheit, obliterating a daily record and flirting with the kind of warmth usually reserved for Memorial Day weekend.
Trenton and New Brunswick weren’t far behind, with readings surging into the upper 70s and low 80s, a good 25 to 30 degrees above the historic average for early March.
For two days, the Shore was cooler, but inland, it was a celebration of sun and a collective exhale after a winter that, while not the worst, had worn out its welcome.
It was a classic “false spring,” the kind that tricks the buds on the trees into thinking it’s safe to emerge and convinces residents that the battle with the elements is won. But Wednesday serves as the final, glorious gasp.
Forecasters expect one more day near 80 degrees, but by afternoon, the mood will shift. The collision of the record warmth with a powerful cold front crashing in from the west will stir the atmosphere into a frenzy.
The National Weather Service warns of strong thunderstorms rolling in late Wednesday, capable of unleashing damaging wind gusts, hail and even an isolated tornado, primarily in the northern and western parts of the state.
Then comes the reckoning. Thursday will be a day of whiplash. Morning temperatures that might start in the 60s will be chased out of town by the afternoon, plunging into the low 40s.
The same front bringing the severe weather will usher in a mass of Arctic air so dense and cold that rain is expected to transition into snow showers by the evening. While significant accumulation is not the primary concern, the sudden drop — with overnight lows plummeting back below freezing — is a violent swing of the pendulum.
“It’s a big transition day, a real ‘March lion roars’ kind of nasty weather day,” said Dan Zarrow, chief meteorologist for Townsquare Media New Jersey, aptly describing the abrupt end to the state’s brief romance with summer.
The irony is as sharp as the incoming wind. This brief warm spell, while welcome, does little to solve a deeper, more troubling problem. New Jersey remains under a statewide drought warning.
Despite a historic blizzard in February that dumped more than two feet of snow in some areas, the liquid equivalent was a mere fraction of what the parched ground and low reservoirs require.
State Climatologist David Robinson notes that 19 of the last 22 months have seen below-average precipitation, leaving groundwater levels in South Jersey and reservoir levels statewide stubbornly low. The warmth of this week only accelerates evaporation, doing the drought no favors.
The long-range outlook suggests this isn’t just a brief cold snap but a potential pattern shift. Meteorologists are watching a split in the polar vortex high in the stratosphere, a disruption that is expected to nudge frigid air southward into the Northeast for the latter half of March.
Following this week’s dramatic temperature crash, the state may settle into a pattern that runs significantly colder than normal, a final, gritty stand from a season that refuses to go quietly.
It was fun while it lasted.
