The Clipper system will become fully absorbed by a strengthening
offshore low pressure system tonight into Saturday. Snow showers
associated with the clipper across the Great Lakes and the higher
elevations of the northern and central Appalachians will gradually
taper off, with leftover lake effect snow showers diminishing by
late Saturday night. Farther east, snow will shift to the coastal
areas of New England as the coastal storm deepens offshore.
Additional light to moderate accumulations are likely,
particularly in far eastern Maine. Snow ends by early Sunday
morning as the coastal storm rapidly pulls away. This will leave
cold and dry weather in its wake with Arctic high pressure
building into the region.

This will be the last Storm Summary issued by the Weather
Prediction Center for this event. Please refer to your local
National Weather service office for additional information.
