...A Major Winter Storm impacting areas from the Great Lakes into the
Northeast except northern Maine today...

...Heavy rain threat over the interior eastern U.S. early today will give
way to fine and cold conditions over the weekend...

...Increasing chance of precipitation moving into Texas and Deep South
this weekend as well as over the Pacific Northwest...

A low pressure system moving across the lower Great Lakes toward New
England this morning will continue to bring widespread impactful wintry
weather through much of the northeastern U.S. today into tonight.  The low
pressure system is forecast to weak as a new low pressure center
intensifying off the coast of southern New England gradually takes over as
the main storm center later today.  The area of snow over Great Lakes will
quickly overspread much of New England today, where 6 to more than a foot
of snow is forecast to accumulate before tapering off later tonight as the
new low pressure center moves rapidly away into the Canadian Maritimes. 
Meanwhile, significant amount of ice of up to a quarter of an inch
possible from much of Pennsylvania through the inland sections of southern
New England this morning before quickly changing over to light snow and
ending later today.  Farther south across portions of the Ohio and
Tennessee Valleys, the threat of heavy rain early today will quickly
diminish as a cold and dry air mass takes over behind the departing storm.
 Below average temperatures will stretch across much of the nation by this
weekend as a cold high pressure system dominates the weather pattern.  The
exception to this will be across portions of the southern Mid-Atlantic and
Southeast where much above average temperatures are forecast as the cold
front will be slow to move out to sea.  The trailing portion of the front
will become nearly stationary off the Gulf Coast this weekend.  Moisture
is forecast to return across southern Texas with chance of precipitation
increasing and heading northeast across the Deep South with a threat of
some wintry weather from Arkansas to Tennessee Sunday morning.
