What to Know

  • Pockets of localized heavy rainfall and a chance of thunderstorms are expected through Thursday night; temperatures continue to be muggy
  • The risk of severe weather is low, but heavy rain and scattered showers are expected across the area for much of the day, prompting flooding concerns
  • Rain will taper off late Thursday night as a cold front clears the area early Friday morning; Showers return Sunday

The tri-state area was hit with a full day of scattered showers and thunderstorms Thursday, a weather system that threatened to bring flash floods to low-lying and other vulnerable parts of the region well into the night, Storm Team 4.

The risk of severe weather is low, though the initial round of storms forced one school district in Long Beach, Long Island, to postpone its first day of in-person classes because of flooding.

Wet conditions greeted New Yorkers at the start of the day, and it never got much better. Intermittent showers swept through the area for hours, with rainfall coming down heavy at times. In parts of Long Island, more than four inches of rain fell in the span of just a few hours at one point, and more than five inches fell between midnight and noon in Massapequa. Towns like Teetertown and Long Valley in New Jersey both saw more than two inches of rain dumped throughout the day.

Flood advisories were in effect for much of the area through Thursday night. Heavy rain and storms were expected to continue through the overnight hours, potentially leading to additional flash flooding in some areas into Friday morning.

A flash flood watch was in effect for parts of central and southern New Jersey until midnight Friday. Click here to see the latest severe weather alerts in your neighborhood.

The rain will eventually move out thanks to an incoming cold front, bringing temps back down into the mid-70s. Clouds could still linger a bit at the start of the day Friday before high pressure builds in from the northwest, bringing back more sunshine by the afternoon along with cooler and drier air.

Heavy rain and flash flooding caused the first day of school at a Long Island district to be canceled. Greg Cergol and Pei-Sze Cheng report.

The weekend will start off feeling a lot more like early fall on Saturday, but conditions will turn muggy, damp and unsettled again on Sunday as highs climb back into the muggy high 70s and scattered thunderstorms possibly hitting the region.
