Long Island and parts of New Jersey, particularly along the shore and in the southern part of the state, bore the brunt of the storm.
It dropped light, fluffy snow across the region, and while it might not look like much, the frigid temperatures and frozen surfaces mean it stuck easily and created slick spots on many roadways.
New York City, which received a dusting to an inch, suspended alternate side parking regulations due to the snow. Meter rules remain in effect.
Salt trucks and plows were out across Suffolk County trying to keep the roads clear.
The snow was starting to taper off across New Jersey by about 6 a.m., but not before slowing the ride to work in many parts of the state.
The roads are slippery, mainly from Monmouth County south. Franklin Township in Gloucester County received 4 inches of snow. Manahawkin in Ocean County has little more than 3 inches and Asbury Park in Monmouth County is reporting 2 inches.
Many schools closed for the day or delayed opening.
Putnam and Westchester counties also had scattered delays due to the light snow.
In Connecticut, a light snowfall made roads slippery and prompted school delays of one to two hours. Schools in Waterbury, Stratford, Naugatuck and Waterford are among those opening late.
It will remain bitter cold after the snow ends, with wind chills making it feel colder. Temperatures will be climbing to the mid-20s, with winds at 10 to 15 mph.
