The storm, which will impact the area for about 12 hours Thursday, prompted schools and school districts to announce closures Wednesday evening.
Snowfall rates of 2 to 4 inches per hour are possible through noon Thursday, according to the National Weather Service.
Snow became heavy after dawn and will continue past midday. Winds will gust between 35 and 45 miles per hour, resulting in near-blizzard conditions at times. Scattered power outages are possible.
The snow is expected to taper off in the mid-afternoon Thursday and wrap up by nightfall with temperatures dropping to the mid-teens.
Much of the Hudson Valley will see between 8 and 12 inches of total accumulation, with locally heavier amounts possible, the National Weather Service said.
