The robust chilly entrance representing the vanguard of a widespread Arctic air mass handed by the DC-to-Philly-to-NYC hall early this morning and temperatures have fallen into the 30’s from early day highs.  Precipitation is being enhanced within the chilly air behind the entrance as a robust jet streak aloft generates upward movement within the I-95 hall.  Consequently, a changeover to snow is probably going in the course of the mid-day and early afternoon hours within the instant DC-to-Philly-to-NYC hall and this changeover to snow is probably going all the way in which to coastal New Jersey and Delmarva.  Some spots may obtain small snow accumulations and as temperatures drop to close freezing later within the day, look ahead to the potential for “black ice” on some roadways.  Precipitation winds down later at present and the chilly will grow to be the principle story with document low temperatures in quite a few Mid-Atlantic/NE US areas by early tomorrow. Widespread information had been set earlier at present from Texas to the Nice Lakes with some stations recording their lowest temperature ever for the month of November and we’re not even on the midway level.
