![]() I got a little lazy here, and decided not to draw a definitive "zero" contour - but those south of Interstate 195 will see very little snowfall here. But little to no snow accumulation is anticipated. South of exit 9 on the Turnpike, you will probably see snowflakes at some point. Roads could get slushy, especially the farther north you are. South of Interstate 78, wintry impacts will be limited to an inch or two of accumulation, at best. This basically translates to "the rest of North Jersey," between I-80 and I-78. Leading to the potential for moderate travel issues. Just to the south of the "snow burial zone" will be a narrow zone of moderate snow accumulation, on the order of 3 to 6 inches. And again, what falls on Tuesday will probably be snow or at least wintry mix - high temperatures will be in the upper 30s to around 40 degrees. Snow may be heavy at times, especially to the north and east. We are still going to see snowflakes falling during the daytime hours on Tuesday, as the coastal low meanders just northeast of NJ. One of the biggest differences in model guidance right now is determining when the storm fizzles out and moves away enough for snow to end. (FYI, all my snowfall calculations are based on an average 7:1 snow to water ratio.) Phase 3: Snow Continues (Tuesday) That also contributes to it being a heavy, wet snow. At or above the freezing mark, again making it very hard to get snow to stick. Overnight low temperatures will dip into the lower to mid 30s. That will limit what falls from the sky going forward to just showers. So in South Jersey, the "faucet" will get turned off by around daybreak Tuesday morning. ![]() However, to the southwest, drier air will start to work in on the back side of this system. And road conditions could go downhill quickly, as snow starts to accumulate overnight in colder North Jersey - especially if we get a band of heavy snow to set up. ![]() By just before daybreak Tuesday morning (5 or 6 a.m.), all of New Jersey should be cold enough to sustain snowflakes. Temperatures will start dropping late Monday evening (again, after about 9 or 10 p.m.), forcing an eventual transition from rain to snow. Well above freezing.Īfter about 4 p.m., rainfall should become steadier and heavier through the evening hours. High temperatures will reach the lower to mid 40s Monday afternoon. ![]()
