The most important note here is that this is a big system and the rains and high winds will likely be the concern around most of the Mid Atlantic.
1. Areas from the Virginia border and southward could see severe thunderstorms with some tornadoes possible later Saturday and early Sunday.
2.Very heavy rain for the Piedmont of Virginia up the 95 corridor with areas receiving 1-3" in Lower Virginia up to 3"+ amounts in Northeastern Virginia and Eastern Maryland up through Pennsylvania
3. Winds will become more and more of an issue Sunday as the Low gets very strong just off the Delmarva area. This will mean power outages and some structural damage possible.
4. Snows will really start to impact the Mountains Later Sunday into Monday with areas seeing 4-8" with isolated higher elevations seeing 12"+. The other factor here will be the high winds (Wind Warning Criteria likely) causing almost blizzard like conditions and tree damage.
5. Coastal Flooding may be somewhat limited, but Bay side flooding is possible as the storm continues high NW winds for a long period of time. this could also mean very low tides with teh offshore winds!
This storm will bring a blizzard to Interior Northern Pennsylvania up through the Middle of New York and New England! Expect travel issues Sunday and Monday from grounded planes due to high winds and snow!
There is a slight possibility that colder air could eventually wrap into the system and cause a brief change to or mix with snow in the Piedmont of Virginia as well. NO accumulations expected.
All for now!
