On the weather map early Sunday morning there is a moisture-starved mid-level disturbance crossing the East Coast states bringing clouds and spotty light snow showers to New Jersey. In fact the disturbance brought a bit of light rain to the area Saturday night. In any event, this batch of “non” precip will be should move completely east of the region by daybreak.
Winds from the southwest behind the disturbance will bring drier air to the area Sunday causing clouds to yield to sunshine. Meanwhile, low pressure will move rapidly from the Great Lakes to near Nova Scotia later in the evening. Clouds and snow showers will accompany the disturbance as it crosses the Lakes and high ground of the interior Northeast however winds from the west in the lowest few thousand feet of the atmosphere descending the Appalachians will preclude precip in the metro region … through a passing flurry cannot be ruled out north over Pa. early Sunday.
Behind this disturbance, a large ridge of high pressure in the upper atmosphere will build over the Southeast states and begin to “flex” its muscle toward the Northeast states. As a result, a warming trend is expected with mainly dry weather from Monday through at least Thursday.
