Long Island weather: Two shots of light snow Friday, bigger storm possible Sunday night

A light snowfall is expected across the region Thursday night into Friday morning and again Friday night into Saturday morning, the National Weather Service said in a briefing Thursday evening. 

There is a potential for one to three inches for Long Island, the service said, but as the second quick-moving storm hits Friday night and continues into Saturday it will mix with sleet.

"Travel may be hazardous Friday evening through Saturday morning, due to a combination of poor visibility and snow- and sleet-covered roads," the service said in the briefing.

 Later in the weekend there might be more snow.

Forecasters said there is a chance for a "more significant storm system" Sunday evening into Monday morning,  though there is "considerable uncertainty" about the track of the storm.

A storm track  farther inland would mean less snow and a track oarther offshore would mean more snow for the coast.
