Thursday’s Long Island forecast calls for increasing clouds and daily highs in the low 40s, the National Weather Service said.

Windchill values will make it feel like between 20 and 30 degrees, with a west wind from 3 to 5 mph, the service’s Upton office said.

News 12 Long Island meteorologist Rich Hoffman said the dry conditions continue through the daytime on Friday. “Some drizzle or spotty showers Friday night and Saturday,” Hoffman said.

Most of Friday offers partly sunny skies and winds shifting east northeast and becoming breezy, up to 15 mph.

Daily highs again are in the low 40s, with a chance overnight of some drizzle or spotty showers, Hoffman said.

Clouds increase on Saturday, with again the chance for a couple of spotty showers or spotty drizzle, Hoffman said. It warms slightly, with daily highs in the upper 40s.

A storm system west of Long Island on Sunday generates warm air, rain and gusty winds, Hoffman said.

Some parts of Long Island could get more than an inch of rain, starting Saturday night and into Sunday morning.

Hoffman also said there’s a threat of snow early Wednesday, as a coastal storm pushes its way north toward Long Island bringing with it colder air.

“With cold air in place, a coastal storm will develop Tuesday into Wednesday. This storm may brush Long Island or go out to sea,” he said.

The farther east and into the Atlantic the storm pushes, the less chance there is for snow.
