A wet Sunday is ahead for much of the Northeast and Mid-Atlantic as an area of low pressure makes it way into the area, which originated from the Southern Plains. Meanwhile offshore, a developing surface low track north from the Bahamas will bring heavy rain to the Outer Banks and portions of New England.
During the morning Sunday, rain will be affecting portions of the eastern Ohio Valley into central New York and New England. There will also be a line of heavy rain and some thunder associated with that coastal storm for the Outer Banks of North Carolina as well as the Tidewater of Virginia. A light rain may also extend into the DelMarVa and along the New Jersey coastline. Then during the afternoon, that line of heavy rain will move offshore from the Mid-Atlantic as the low pressure takes an easterly turn. Some of that heavy rain may clip Cape Cod and the islands off from Massachusetts. The primary rainmaker for the Northeast, however, will be the inland low pressure. Rain is expected from the central Appalachians through central New York and northern New England. Much of the I-95 corridor will be dry with occasional showers, including a few isolated showers and storms that develop over the Mid-Atlantic.
Overnight Sunday, much of the activity will begin to quiet down. A round of rain will move into eastern Pennsylvania and New York, the rest of New England, and New Jersey. The spotty showers over the Mid-Atlantic will diminish, but back toward the Ohio Valley, showers and storms will actually develop at around sunset, turning into a line of rain and thunderstorms across the region. This line will contain gusty winds, but it will only be able to hold itself together for a few hours before dissipating early-Monday morning.
Speaking of Monday morning, the rain may actually changeover to a light to moderate snow across inland and northern Maine. Thankfully, it will be too warm for much accumulation but it will be May 7th by then.
