Winter Storm Warnings have been issued for most inland areas of Northern New Jersey, Connecticut, and the Hudson Valley. Surrounding counties, including New York City, Long Island, and South Coastal Connecticut, are under Winter Weather Advisories. In addition, Eastern and South Central Pennsylvania have been placed under Winter Storm Warnings, with advisories for surrounding counties, including Philadelphia. The Eagles Rams game on Sunday promises to be an entertaining watch.
The rain is expected to move away from the coast this evening, leaving mostly dry conditions on Sunday morning. A cold front is moving offshore, and there is a forecast of low pressure developing in the Southeast US. This low pressure system will then move northeastward, passing offshore and to the east by late Sunday afternoon and evening. The loop below shows the GFS model’s prediction from 10 am on Sunday to 1 am on Monday.
Snow will develop around midday across Southern Pennsylvania and Maryland, and it will then reach NYC during the early afternoon, advancing into Southern New England in the mid and late afternoon. This system is moving quickly, so it won’t have enough time to produce significant amounts of snow. However, there is a possibility of 5 to 8 inches in the Winter Storm Warning area and 3 to 5 inches in most advisory zones.
As the snowfall begins, the temperatures will be slightly above freezing or near that range. Along the coast, there might be a brief period of rain before transitioning into snow, as the temperatures drop into the 20s once the snowfall becomes more consistent. Throughout the day, the temperatures will continue to decrease, and by the time the snowfall ceases in the late evening or around midnight, starting from the southwest and moving towards the northeast, the temperatures will be in the low to mid 20s. By Monday morning, the temperatures will further drop to the teens. Following this, colder and bitter air will prevail in the upcoming week. By Tuesday morning, the temperatures are expected to be in the single digits, and in colder inland areas, they may even drop below zero.
