The same cold front poised to mark an end to the midsummerlike warmth in the Northeast will also spread rain and thunderstorms into the region as May transitions to June.
Warmth and humidity surging into the Northeast to start the weekend will not mark another long stretch of warm days. The warmth, instead, will be truncated by the front.

The front will bring noticeable cooling and rain to northern New England and the eastern Great Lakes on Sunday but will be slower to erase the summer warmth to the south.
Showers and thunderstorms rattling the Appalachians on Saturday will spread to the I-95 corridor on Sunday.

People who have outdoor plans from Boston to Washington, D.C., should take along some rain gear on Sunday. MLB games in Philadelphia, New York City and Baltimore could be affected by rain.
The afternoon hours will prove to be wetter than the morning from New York City southward.
A shower or thunderstorm may sneak into Dover, Delaware, Sunday afternoon and interfere with Sunday's NASCAR radar at the Monster Mile.
There is concern for some of the thunderstorms on Sunday, mainly in the afternoon, to turn violent with damaging winds, hail and blinding downpours.
The threat is greatest from western North Carolina and Pennsylvania to extreme southern New England. This includes Pittsburgh and Harrisburg, Pennsylvania; Asheville, North Carolina; Roanoke and Winchester, Virginia; Hagerstown, Maryland; Poughkeepsie, New York; and Providence, Rhode Island.
The majority of the strongest thunderstorms should remain north and west of New York City, Philadelphia and Washington, D.C.

Regardless of the severity of the thunderstorms, the danger of being struck by lightning is present as soon as thunder is heard.
Some locations may receive their most significant soaking of the entire month. An inch of rain could fall in places with higher amounts in some neighborhoods.
As the front's forward speed slows, rain will linger Sunday night into Monday across the Northeast and mid-Atlantic as cooler air presses into southern New England and the central Appalachians.
The clearing and drying process may be slow to evolve from Virginia to Long Island into the middle of next week.
