There are going to be two rounds of weather to deal with. Some places get one round and some will see both rounds. Round 1 begins tomorrow morning over South Central and Southeast Pennsylvania and then spreads into some of th Northern Counties of New Jersey mainly north and west of the New Jersey Turnpike (I-95).

Once the lead weaker piece of energy aloft plays out Monday the stronger piece to the west will come in for Monday night and Tuesday and this begins a second round of Winter Weather Advisories that cover Southeast Pennsylvania northeast to Northern New Jersey (NW of I-95) to the Hudson Valley north of Route 287 and Connecticut north of I-95.

it is a combination of snow, sleet, freezing rain, and rain here as well as a very cold low level atmosphere and a 32 degree line that will be rather stubborn. Ice i believe in the end will be the bigger issue here verses snow. The snow amounts will range from as little as a coating to maybe a few inches in some places. Ice accumulation up to .15 inch is challenging though by no means apocalyptic! Still ice is something no one wants to fool around with.

This is the Ice Accretion Forecast from the National Weather Service forecasting up to two tenths of an inch of ice in parts of NW New Jersey from this. The odd spot seems to be in South Central Pennsylvania where you don’t see much forecast and then suddenly it all starts along the Maryland state line. I’m sure how much of this is topography or just two weather service offices with two different opinions. I broke the tie using the Weather Prediction Center’s ice probability forecast for at least one tenth of an inch.

As far as snow accumulations go, these are two day totals. Most of what falls in Southern Pennsylvania south of Route 78 will be on Monday and north of Route 78 Monday night and Tuesday. Again snow is not the issue here. Ice will be.

A coating to maybe a couple of inches accumulates from this. Then the second round with the main low Monday night and Tuesday is the surge that brings the icing issue to most of the area inland of the coast.

Once the low moves out colder air arrives on gusty winds and another cold front Wednesday. We get a few snow showers with that. Then it is dry and cold for the rest of the week.
