A slippery start with some snow Wednesday morning

John Cifelli, Meteorologist | December 10, 2019 | Weather
  • A cold front is slowly moving across New Jersey Tuesday afternoon and evening
  • Rain showers will change to snow late Tuesday night
  • Snow lingers into Wednesday, ending mid-morning
  • Colder days to follow through the end of the work week

It’s been a wet start to the week across New Jersey as a strong low pressure center moved through the Ohio Valley and into southeast Canada, bringing rain to the Garden State on Monday and Tuesday. The trailing cold front is slowly trudging across the mid-Atlantic, set to usher in an Arctic air mass for the next few days. As this cold air works in, it will change precipitation along the frontal boundary from rain to snow. This will not be a large accumulation event, but the timing of the transition may make for some slippery sledding tomorrow for the morning commute.

Expect spotty showers to continue Tuesday afternoon, and enjoy the seasonal warmth. Some spots in New Jersey are close to 60 degrees this afternoon. Precipitation will remain as rain through the early evening everywhere. Around 8 or 9 p.m., beginning with the elevated portions of northwest New Jersey, a gradual transition from rain to snow will begin. After the warm day Tuesday and wet surfaces, I wouldn’t expect and travel troubles through midnight.

As the night continues into the pre-dawn hours of Wednesday, the changeover to snow will continue to slide south and east, and everyone is cold enough for snow by 6 or 7 a.m. Precipitation will have already ended for north and western portions of the state. For the coast and interior Southern and Central New Jersey, I think snow is still falling through the morning commute, and it could cause travel problems for a period. By 9 or 10 a.m., it’s over everywhere.

Look for a coating to two inches statewide, with up to 3 inches in coastal counties. This won’t be a big deal for most, but might require a little extra time than usual to get where you’re going Wednesday morning. The rest of the week looks cold, with high temperatures in the mid-30s Wednesday and Thursday, with lows dipping towards the teens.
