Wednesday's forecast mild, high near 70s

Long Island is set to dodge whatever wintry precipitation may be in the works for the northeast this weekend, the National Weather Service said Wednesday morning.

"Not even a wet snowflake is expected," said Tim Morrin, a meteorologist in the weather service's Upton office. There may be a period of "wet snow" far inland, but it will not affect the Island, he said.

"We are expecting a fairly vigorous coastal storm to take shape Saturday," he said, but it will develop far out into the Atlantic, sparing Long Island.

That said, Saturday will be "kind of a raw feeling day," Morrin said, with periodic light rain late morning into afternoon. Temperatures are expected to reach only 50 -- chilly but not cold enough for snow -- with an ocean breeze. Precipitation should taper off into midnight Saturday.

The watchword for Sunday is "windy," Morrin said, with temperatures in the mid-40s. There will be winds from the northwest, with gusts of about 25 mph, close to 30 mph, he said, and some sunshine as the storm moves away.

Wednesday's weather is milder, with a high expected to be near 70, Morrin said. It will be a very moist, humid day with increasing clouds. The best chance for showers is after midnight, he said, but with a 40 percent chance of precipitation "portions of Long Island might not get rain."

Skies should begin clearing on Thursday, and Friday looks "partly sunny" with temperatures in the mid-50s for Halloween.

"Trick-or-treating should be said and done" by the time clouds and a chance of rain come into the forecast for later Friday evening, Morrin said.
