Coastal Storm Soaking Mid-Atlantic

UPDATED By WeatherBug Sr. Meteorologists, John Bateman and James West
The Eastern Seaboard will remain quite soggy through the rest of the week, with gloomy weather poised to last into the weekend, all thanks to a pesky storm spinning off the Mid-Atlantic coast.
An area of low pressure is spinning off to the northeast of the Outer Banks, drawing a strong tap of Atlantic moisture into the Mid-Atlantic. This is leading to a soaking from Virginia into New Jersey and Pennsylvania.
Rainfall totals on Wednesday reached 3-to-4 inches near Norfolk, Va., causing areas of flash flooding. As the storm`s downpours moved northward through the Delmarva, total rainfall of 1-to-2 inches have been common since Wednesday evening from the shores of the Chesapeake Bay to the Delmarva Peninsula.
The low will continue to lumber north and eastward throughout the day, taking up a position off the southeastern Virginia coastline. This will continue to bring soaking downpours to the Mid-Atlantic. Additonal totals of 1-to-2 inches, with locally higher amounts, are possible across central Pennsylvania, central Maryland, north-central Virginia, much of Delaware, and southern New Jersey through Friday morning.
The rain comes right on the heels of the passage of a strong cold front on Monday, which brought 1-to-2 inches of rain from New England to the Mid-Atlantic. The latest deluge could be enough to trigger flooding east of Interstate-95, despite the recent dry trend.
Coastal flooding will be an issue as well, with Coastal Flood Advisories and Warnings in effect from the Hampton Roads area of Virginia to northern New Jersey, including Delaware Bay and the Chesapeake Bay. Tidal surges of 1-3 feet above normal will be possible in these locations, with moderate flooding likely in low-lying areas.
Another aspect of this storm will be the northeast winds. Along the Mid-Atlantic Seaboard, the winds will cause some coastal erosion. Inland, winds will gust at 20 to 30 mph, creating a real bite to the air.
The low will sit and spin in place before being shifted southward again on Sunday by high pressure building southward from New England. This will cause it to weaken throughout the weekend, leading to a few days of drizzle and scattered showers. Ultimately, the drier air will win out, with a few breaks of sun possible Sunday and a return to sunnier conditions by Monday and Tuesday.
