NEW YORK – On Sunday, an area of low pressure will begin to stall over the Ohio Valley and a feed of moisture off the Atlantic Ocean, pointing it toward the Northeast.
Scattered downpours with occasional claps of thunder are likely across much of the region, but especially near the Catskills and Poconos of New York and Pennsylvania. It won't be a complete washout, and you can expect breaks in the action, which in some cases may last a few hours.
Warning boxes are color coded as: Severe Thunderstorm Warnings in yellow, Tornado Warnings in red, Tornado Warnings with confirmed tornado in purple, Flash Flood Warnings in green, and Flash Flood Emergencies in pink.

This type of setup is a hallmark for long-duration rain events as a persistent wind flow aloft creates a funnel of atmospheric moisture off the Atlantic that will stay pointed at the Northeast.
It won't rain every minute of the day, but several rounds of showers with embedded downpours can be expected through at least Tuesday. Widespread rainfall totals will reach 2-3 inches across much of the Northeast by the middle of the week, with isolated areas reaching up to 5 inches.

The FOX Forecast Center says, although the rain will initially be beneficial given the ongoing areas of drought, heavier rain late Sunday into Monday and again on Tuesday could pose the risk for some instances of flash flooding.
Given the recent wetter trends in computer forecast model guidance, the Weather Prediction Center has issued a multiday flood outlook from Saturday through Monday that includes Charleston, West Virginia; Washington, D.C.; New York City, and Hartford, Connecticut.
