Probability of accumulating snow pretty low
Indications are strong that a major storm will impact New Jersey to New England with some significant snows, especially the further north you go Sunday night. But once you get south of Jersey, precipitation amounts will likely decrease from northeast to southwest through the Mid-Atlantic. For the metro area, a period of rain should develop Sunday afternoon and evening. Depending on how fast the storm develops and taps cold air to the north, the precipitation may mix with and change to snow for a time Sunday night. The storm should then quickly move away very early Monday morning. A lack of cold air coupled with the fact the storm is likely to undergo its greatest intensification to the north reduces the risk of significant snow in the metro area.
There is now about a 40% chance of accumulating snow, down from my earlier assessment of a 55% chance in the Snow Lover's Crystal Ball posted this morning. Also posted this morning, the general forecast for today and tomorrow.
