Windy & Colder Weather Returns, Flurries Later Today through Tuesday. A Clipper With Some Snow Wednesday into Wednesday Night.

Discussion:

After our Snow, Ice, and Rain event yesterday and last night, We'll return to a Windy and Colder pattern for later Today into Tomorrow. Low pressure now strengthening along the New England Coast, is producing heavy snows, over Central and Northern New England. As this storm deepens, strong winds and CAA with begin this afternoon and continue into Tuesday.

Some flurries are possible from later this afternoon into tomorrow, as a strong NW flow, and a weak disturbance, move through the region. The main factor will be increasing winds, out of the NW this afternoon and tonight. Winds Advisories have been issued for the entire Delaware Valley for both Today and Tonight. Temperatures will drop into the 30's this afternoon, and into the mid and Upper 20's tonight. Scattered Flurries also can be expected.

I'm going with winds of 15-30 Mph and Gusts to near 45 Mph for later today and tonight. These Windy conditions will continue tomorrow, out of the west at 15-25 Mph. with Gusts to near 40. Expect Variable Cloudiness and scattered Flurries. Highs will be in the mid to Upper 30's. Tuesday Night winds will finally calm down as our system pulls away, and weak High Pressure Builds in.

An Alberta Clipper system will move just to our south (Central VA) on Wednesday, and exit off the Delmarva Coast Wednesday Evening. As usual, these Clippers are fast movers, and have limited moisture to work with. It now appears SE PA, Central/Southern NJ, and DE, will be in the best spot for some light snow accumulations.

With the track of this system being just to our south, the swath of light snow will set up to the north of the Storm's Center, in a 100 to 150 miles wide swath. My best estimate is for Light Snow and Flurries to move in Wednesday Afternoon, followed by a period of Light Snow, Early Wednesday night. A General snow accumulation of 1" to 2" is possible over the entire Delaware Valley, especially in Southern/Central NJ and Northern DE, where some spots could see near 3" amounts.

I'll have a better handle on this system later tomorrow, and will make my Call and forecast on Tuesday Night.

Take Care,
Ruggie
