Discussion
Another Arctic blast arrives later this evening in the Mid-Atlantic region and this one will be colder than the last one. In fact, temperatures on Thursday and Friday are likely to hold in the 20’s on both days and overnight lows by early Friday morning could bottom out in the upper single digits near New York City, not far from 10 degrees in the Philly suburbs, and around 15 degrees in DC. This bitter cold, dense Arctic air mass will then retreat on Saturday, but not before moisture reaches us from the Midwest. This collision of moisture and retreating Arctic air could lead to accumulating snow and/or ice in the DC-to-Philly-to-NYC corridor late Friday night/early Saturday before a mid-day changeover to plain rain.
