The strong cold front representing the leading edge of a widespread Arctic air mass passed through the DC-to-Philly-to-NYC corridor early this morning and temperatures have fallen into the 30’s from early day highs. Precipitation is being enhanced in the cold air behind the front as a strong jet streak aloft generates upward motion in the I-95 corridor. As a result, a changeover to snow is likely during the mid-day and early afternoon hours in the immediate DC-to-Philly-to-NYC corridor and this changeover to snow is likely all the way to coastal New Jersey and Delmarva. Some spots could receive small snow accumulations and as temperatures drop to near freezing later in the day, watch for the possibility of “black ice” on some roadways. Precipitation winds down later today and the cold will become the main story with record low temperatures in numerous Mid-Atlantic/NE US locations by early tomorrow. Widespread records were set earlier today from Texas to the Great Lakes with some stations recording their lowest temperature ever for the month of November and we are not even at the halfway point.
