The rest of New Jersey remains under winter weather advisories with at least 1 inch of snow expected statewide.

The National Weather Service said snow overspread most of the region as anticipated after midnight.

Snow will move out rapidly once the storm departs, with most areas dry by noon.

“In the wake of the snow, we turn bitterly cold and windy,“ the national weather service said ”Winds increase today reaching upwards of 30-40 mph into tonight. There is the potential for blowing snow today causing reduced visibility”

Temperatures will remain cold, only reaching the upper 20s to low 30s today.

Tonight brings the coldest conditions of the season so far, with lows dropping into the teens for most of New Jersey and wind chills plummeting toward zero in many areas.
