The heaviest rain showers have pretty much cleared the area, leaving behind the chance of pop-up showers followed by a chance of more widespread precipitation after midnight, said Michael Silva, National Weather Service meteorologist based in Upton.
Long Island could see another quarter of an inch of rain by Tuesday night, he said, on top of Monday's 1.2 inches in Northport, 0.91 in East Farmingdale, 0.78 on Fire Island and 0.62 at MacArthur Airport.
Tuesday will be muggy with highs in the mid-70s and showers could pop up anytime in the morning. They should taper off by the afternoon, Silva said.
But the unsettled weather pattern will last throughout the week, with a chance of showers every day through Friday, the service said.
The weather was causing some average arrival delays Monday of about 1 hour and 45 minutes at LaGuardia Airport and an hour and a half at Kennedy, with some departures also affected, according to the Federal Aviation Administration. Some flights at Long Island MacArthur airport were also affected, and the FAA advised travelers to check with their airlines.
