An area of low pressure will continue to move towards our area today and will strengthen as it hits the east coast. As a result, snow will develop tonight and last through tomorrow. As the storm strengthens, it will deliver blizzard conditions and several feet of snow for portions of the the northeast, including New York city and Boston.

As for our area, the storm will likely strengthen too far away for us to see a major snow storm here. The eastern shore will be on the fringe of the heavy precipitation and will likely see more snowfall than areas west of the bay.
