...Powerful winter storm to produce significant impacts across parts of
New England and coastal Mid-Atlantic/Northeast on Saturday...

...Well below average temperatures will expand across eastern third of the
country this weekend before moderating next week; Great Plains warm up
this weekend...

An area of low pressure is forecast to develop off the Atlantic coast of
Florida this morning. This low will rapidly intensify as it travels north
throughout the day. Moderate to heavy snow and strong winds are forecast
to materialize along the Mid-Atlantic and Northeast coast this evening as
the low arrives off the coast of North Carolina. Some light to moderate
amounts are also likely to spread into parts of the Southern Appalachians.
Heavy snow and intense winds are then likely to spread into New England on
Saturday as the Nor'easter intensifies even more off the Northeast coast.
Blizzard conditions are expected across portions of coastal New England,
particularly from southeast Maine to Cape Cod which will make travel
nearly impossible. Beach erosion and coastal flooding will also be a
concern. Winter Storm Watches and Warnings are in effect for much of the
coastal Mid-Atlantic up into the coastal Northeast. Winter Weather
Advisories and Warnings are in effect for parts of the Central/Southern
Appalachians. The heaviest snowfall is likely to fall across a swath
extending from the Eastern Shore of Maryland up through most of Maine
where 6-12 inches is expected. Parts of coastal New England where blizzard
conditions are forecast may see between 1-2 feet of snow with locally
higher amounts possible, particularly over coastal Massachusetts.

Bitter cold air will follow behind the Nor'easter and plunge temperatures
across the eastern third of the country on Saturday where highs will be
15-25 degrees below average in most places. The cold snap will come to an
end by the start of the work week.
