Discussion
Low pressure that formed along an Arctic frontal boundary zone is now pushing to the east and colder air has worked into the region from the north-to-the-south. There can be a mix of rain and snow this morning with a change to all snow likely before precipitation winds down and there can be coating to an inch or so mainly on non-paved surfaces. After Arctic cold air floods the area tonight and Saturday, the next storm system will be suppressed well to the south - sparing the region of any late weekend snowfall. A third and powerful storm is likely to develop near the Mid-Atlantic coast in the late Monday night or Tuesday time frame and it could intensify rapidly near the coastline with lots of cold air in place – in other words, big potential from a monster-looking storm. Stay tuned, one of the trends to watch over the next few days will the exact storm track as one just inland could bring enough warmer air in from the ocean for a changeover of snow-to-rain along and east of I-95.
