The first snowfall of the season lightly dusted parts of Long Island Sunday evening, but the snow flurries were not expected to last past midnight, according to the National Weather Service in Upton.

“There are areas of light snow in Suffolk moving into Nassau County, that may taper off around midnight,” said Matthew Tauber, a meteorologist with the service.

Tauber said light showers may occur overnight, but slow flurries were not expected for the Monday morning commute.

Forecasters said heavy winds and showers would continue into Monday, with highs in the low to mid-40s and wind chills around 30. The low is forecast to be around freezing.

There will be a slight warm-up Tuesday with highs in the mid- to upper 40s. Winds will still be strong but subsiding a bit, with gusts of 30 to 35 miles per hour, Ciemnecki said. It will be mostly sunny. Lows will be around freezing.

Wednesday, high temperatures will be in the upper 40s and lows in the upper 30s, under mostly sunny skies. Winds will be lighter.
