Thursday’s daytime high will be a comfortable 76 and the clouds are slightly deceptive as the National Weather Service in Islip expects no rain before the night and then the odds are just 40%.
The chances of downpours are the same on Friday but it will be a cooler 67 ahead of a sunny spell that runs all the way through the weekend to Wednesday.
Though Hurricane Sally, which the weather service warned brought widespread floods and record-setting rain to much of Georgia, has declined to a tropical depression over southeast Alabama, its tentacles may reach as far north as Long Island.
Thursday’s clouds can be pinned on the storm, one of a series pummeling the Atlantic this year. "Mainly dry conditions are expected today, however clouds will gradually increase from the south as the remnants of Sally move towards the Middle Atlantic states," the weather service said.
Ocean beaches on Thursday will present swimmers and surfers with a moderate risk of rip currents, it said. The possible showers that may arrive Thursday night and last into Friday are the result of a Great Lakes cold front encountering a much weakened Sally, the weather service said.
Though the weekend sunshine will only raise thermometers to the mid-60s, look for the daytime high to reach 74 by Wednesday.
And it is possible the Island may be at least tangentially affected by another developing storm, Hurricane Teddy, now 625 miles east northeast of the Lesser Antilles that could travel north — but stay well offshore — arriving off the coast of Virginia before dawn on Tuesday.
Possibly, "Teddy could make a left-hand turn into the East Coast. Both runs show this happening in Maine which is a bit too close for comfort," the National Weather Service said.
