1/31/17 AM All Zones: Some Snow, Especially for Northern Areas Today
Skies will remain mostly cloudy today, as a clipper system coming out the Great Lakes. Snow is still anticipated for many parts of the region, especially north of Central New Jersey. Primary low pressure will weaken and stay northwest of the region. While a secondary low begins forming just south of Long Island and then tracks northeast over Cape Cod or Nantucket regions during the evening hours.
Snow will begin breaking out from west to east across much of the region between 8am and 11am this morning then continues into at least the early afternoon hours. This is primarily due to isentropic lift, from warm-air advection the mid-levels of atmosphere occurring over a colder airmass remain more stubborn near the surface. Surface temperatures will be in the 20s and lower 30s during this band. So some light accumulations are likely, north of Central New Jersey
