Discussion
Low pressure that has 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. Snow should overspread the area this morning and last into the mid-day or early afternoon hours and there can be a couple of late afternoon snow showers – perhaps even a heavier snow squall - with total snow accumulations possible on the order of 2-4 inches. 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 potential monster storm is likely to develop near the Mid-Atlantic coastline 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, lots of snow potential. 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.
