Newark, New Jersey – A milder air mass building into the Mid-Atlantic ahead of St. Patrick’s Day will push most of New Jersey toward rain during the day, but nighttime cooling could still allow brief rain-to-snow transitions between March 11 and March 17.
According to the National Weather Service Climate Prediction Center, New Jersey remains within a 40-50% probability zone for above-normal precipitation during the 8-14 day period. Temperatures are projected to trend near to slightly above seasonal averages statewide. That warmer pattern favors rainfall for much of the state, though marginal overnight readings may still support wet snow in spots, especially away from the immediate coast.
In Newark, Jersey City and along the Interstate 95 corridor, daytime highs in the 40s and possibly low 50s could keep most precipitation liquid. However, if steadier precipitation lingers after sunset and temperatures dip into the lower 30s, wet snow could briefly accumulate on grassy areas and untreated secondary roads. Inland communities along Interstate 78 and into northwestern New Jersey, including Sussex and Warren counties, face a slightly higher chance of nighttime snow mixing in.
Along the Garden State Parkway and Atlantic City Expressway, reduced visibility is possible during steadier rainfall regardless of precipitation type. Coastal influence should limit any accumulation near the shore.
Drivers across New Jersey should monitor overnight and early morning road conditions where temperatures hover near freezing. Even brief wet snow can create slick spots on bridges and elevated highways. Additional updates are expected as the March 11-17 window approaches and system timing becomes clearer.
