Heavy rain, high winds, and snow Sunday night thru Monday night

Summary: 

A complex storm system will affect the area in the Sunday evening through late Monday night time frame. Light rain and rain showers will arrive by Sunday evening over much of the area. The main low, originating from the northern Gulf states, will move northeastward through the Tennessee and Ohio Valleys, and eventually toward our area, and sliding east toward the coast from there. High pressure center well to the northeast, albeit retreating, will be at the same time positioned over southern Quebec. The system pulls away Monday night and perhaps very early Tuesday. 

Impacts and Timing:

*Locally heavy rainfall possible to exceed 2″ in southern and eastern sections.

*High winds, especially early Monday, could reach 55mph in gusts for some areas closer to the NJ/DE coasts.

*Snow/sleet possible in areas of elevation in parts of North Central and Northeast PA on Monday afternoon/evening with heavier precipitation rates.

*Coastal flooding and beach erosion possible on a hyper-local level, mainly in the coastal counties of NJ and DE. Inland flooding is not expected with combination of lower amounts and precipitation is spread over a wide timing window.

*Best timing for the entire event is broad, from Sunday evening through at least Monday night, perhaps early Tuesday morning with residual showers as the system pulls away.

Technical discussion

The biggest issue with this system will likely be the wind and coastal flooding, despite significant rainfall expected for much of the region. Since the rainfall will be over a 24-36 hour period, urban and flash flooding is not an immediate concern. 

Winds are expected to be at its worst when the pressure gradient tightens from the pre-dawn hours on Monday through 12-3pm Monday depending on location. Monday morning wind gusts could be anywhere from 40mph to as much as 60mph, and again, location dependent.

It is this period that we will be watching for coastal flooding, and possible beach erosion in coastal DE and NJ. The chart below is a model surge forecast for Cape May, NJ for Monday, which peaks Monday morning:

surge

Another lesser impact of this system will be a change to snow in the higher elevations of north central PA over to northern NE PA, the areas closest to the NY/PA border seeing the best chance for that to occur. This will likely change rain over to sleet… and then snow for mainly areas of elevation, and during a time when heavier precipitation occurs Monday afternoon/evening. The dynamics will be enough to overcome any mid-level warm layer aloft and change the precipitation to sleet, and then snow where indicated on the snow/sleet accumulation map. Farther south, the warm layer will be too deep for even the best dynamics to overcome, and a cold rain will continue. It is not impossible for areas south of the grey southern border to see sleet mix in during times of more intense precipitation, but overall, no accumulations are expected farther south.
