Winter Storm Warnings in effect through Wednesday
The second winter storm in 48 hours time will impact the area beginning Tuesday Night and continuing into Wednesday. Despite occurring less than two days after a significant snowstorm which blanketed the area with 8-10″ of snow from Sunday into Monday, this system will feature an entirely different set of threats — and will also feature a completely different evolution. A low pressure system is forecast to drive from Tennessee Valley into the Ohio Valley and Western Pennsylvania, while a secondary surface low redevelops off the coast of New Jersey. The result will be heavy precipitation overspreading the area Tuesday Night, and mid level warm air advection rapidly surging northward.
At the surface, cold air looks to be stubborn — especially away from the coast. The result will be a storm featuring snow which will quickly transition to sleet, freezing rain and rain throughout the area. Coastal locations and areas farther south will be warmer initially and likely will changeover to plain rain after just light accumulations. But farther north and across interior New Jersey, Southeast NY and parts of CT — significant low level cold will be slower to scour out. And the result will be the potential for several inches of snow followed by icing, which could create a high impact storm system with travel hazards and power outages into Wednesday. The National Weather Service issued Winter Storm Warnings in advance of the system, which are in effect for Tuesday Night into Wednesday.
