While all good things must come to an end, the forecast turns a bit pessimistic by the end of the weekend. On a better note, it's mostly cloudy skies that will ruin the weekend, but this forecast will need to be watched.
Another nice day on Friday made it "third time's a charm" in the weather department. Lots of sun, low humidity and highs in the 70s. Although fair-weather clouds came in quickly for the afternoon, it was a nice day overall. MacArthur Airport's morning low Friday was 57, a few degrees shy of a record. For Saturday morning, both the record low and forecasted low are 58 degrees, says the National Weather Service in Upton.
High pressure continues to control the weather for the Northeast, but will break down a bit come Sunday. A frontal boundary stuck in the Southeast will give in. It heads up the East Coast and brings clouds to the area for the latter half of the weekend. Beforehand on Saturday, fair-weather clouds dominate, so by the afternoon, it's partly sunny and the seabreeze kicks in. Highs will be near 80 with a bit higher humidity levels. Then the clouds stream in for Sunday.
Recent computer model runs show precipitation coming in as well, so that is not out of the question that a few showers fall on Sunday. Up until now, most model solutions offered a dry forecast with rain staying south of Long Island. As time passed, the models changed their tune, offering up a little rain for the tri-state area.
Right now, the rain does not look to be associated with the remnants of the tropical cyclone in the Gulf of Mexico. On Friday, the National Hurricane Center still had it on its watch list, and was not named as of Friday afternoon. Although there is uncertainty with its track and effects, it may head toward the U.S. Gulf coast and fizzle out.
Warmer and more humid weather is expected next week with a slight chance of storms early in the week.
