Long Island Weather: How Much Snow Is Coming Friday

LONG ISLAND, NY — The National Weather Service has issued the following hazardous weather outlook for Long Island:

Low pressure is expected to produce a round of snow late Thursday night into Friday. Although there is still some certainty regarding the exact track, timing, and intensity of the system, a general 2 to 4 inch snowfall is expected across the area. The snowfall is expected to impact the Friday morning commute.

"The overall model trend has been east with the system, so it would not be surprising to see a further eastward trend in future model runs," the weather service said in a forecast discussion Wednesday evening. "Any trend west would produce more snow."
