Scattered rain showers are changing to a wintry mix and then snow from now and through 6 p.m. Once the changeover occurs near you, expect periods of snow showers with lower visibility through mid-evening. Snow showers will end by around 7 p.m. to 8 p.m. for much of Long Island.

Most roads will stay wet as snow falls, but a coating of snow is possible on grassy and colder surfaces. Use caution traveling!

Areas of black ice will form after the snow showers end as temperatures drop to around or slightly below freezing overnight and into Friday morning.

On Friday, expect a partly sunny day. Breezy, with a high temperature in the lower to middle 40s. As we head into the weekend, temperatures will return to the upper 40s to around 50 degrees with a mix of sun and clouds. Clouds will build on Sunday as our next storm approaches Long Island. Expect rain and gusty wind on Monday with highs in the 50s. Once the cold front passes on Monday night, skies will clear and sunny and chilly weather arrives for Saint Patrick's Day.
