Heavy rain, flash flood threat return to NYC area Sunday. Get the First Alert Weather Day forecast.

Rainy weather returns to the New York City area Sunday, bringing with it the threat of flooding.

A First Alert Weather Day has been issued for later on Sunday due to the threat of heavy rain that may lead to flash flooding.

To start off Sunday, partly cloudy skies will be in place. As the day progresses, clouds will increase, along with rising levels of humidity. More cloud coverage will keep highs only in the lower 80s.

Most of the day should remain dry until the late afternoon hours. By that timeframe, rain will start creeping in from west to east. The rain could be heavy at times, especially for locations south of the city. A few thunderstorms are possible as well.

Although the severe threat is rather low, the flash flood risk is slightly elevated – a level 2 out of 4.

Rain and embedded storms will continue through the overnight hours of Sunday, lasting into the early portions of Monday.

Once all is said and done, rain totals are likely to average between 1-2 inches for most of the area. Some locations may receive higher totals.

Sunny skies then return for Monday afternoon.
