Up to an inch of rain is expected to drop on Long Island Thursday, forecasters said, and high-velocity winds and warm temperatures could mar trick-or-treating Halloween night.
“Showers are moving into the area now that are associated with a warm front over the Ohio Valley right now,” said Matt Wunsch of the National Weather Service in Upton. “Through tonight and through tomorrow we expect more showers in the area.”
Temperatures will reach nearly 70 degrees during the day, the weather service said. But as Friday evening approaches, Wunsch said, rain could pick up, even leading to thunderstorms overnight between 11 p.m. and 2 a.m.
And winds will be fierce, Wunsch said, reaching between 50 and 60 mph, prompting officials to issue a wind advisory after 8 p.m. Thursday.
“That is mainly going to be around or after midnight," he said. “Fortunately, it is temporary.”
By daybreak, Wunsch said, the rain should stop, leading to a pleasant Friday with gradually sunnier skies but a cooler turn in temperature to a high of about 52 degrees with gusts as high as 33 mph.
Friday night will be clear with a low of 38 degrees.
The weekend days should have temperatures in the mid-50s and lows in the high 30s or low 40s after dark.
