...A Major Winter Storm to affect areas from the Great Lakes into the
Northeast...

...Flash Flooding threat will continue across portions of the Tennessee
and Ohio Valleys...

...Below Average Temperatures across much of the nation over the next two
days, except for the Southeast...


The second major winter storm to affect the nation this week will be
moving from the Tennessee/Ohio Valley region Thursday night to a position
off the New England coast during Friday.   The winter weather effects
currently from this storm across portions of the Southern Plains into the
Mid Mississippi Valley will be diminishing tonight but increasing from the
Great Lakes into the northeast.  Accumulating snows expected Thursday
night from the Upper Mississippi Valley into the Great Lakes, spreading
into the Northeast by early Friday.  The heaviest snows expected from
along the Pennsylvania/New York State border, across much of New York and
much of New England, except northern Maine.  Snow accumulations in the 6
to 12 inch range possible across these regions, with lighter totals
westward across the Great Lakes into the Upper Mississippi Valley.  
Accumulating ice possible to the south of the heavy snow region from Ohio
into Pennsylvania and northern and western Maryland, where .10-.25"
amounts are possible. 

Farther to the south, heavy rains are possible tonight into the early
morning hours of Friday across portions of the Ohio and Tennessee Valleys.
 These regions have received heavy rains over the past three days,
resulting in high stream/river flows and saturated soil conditions.  The
expected additional rains will pose the threat of additional flash
flooding and river flooding. 

In the wake of the storm system moving northeastward off the New England
coast on Friday, below average temperatures will stretch across much of
the nation.  The exception to this will be across portions of the Southern
Mid-Atlantic and Southeast where much above average temperatures are
possible.   Record low minimum temperatures are possible Friday morning
from western Oregon, through much of California and into western Arizona. 

By Saturday, much more tranquil weather will dominate the nation with only
some light precipitation amounts developing over the Southern Plains and
moving into the Pacific Northwest.  Temperatures will also begin to
moderate on Saturday along the West coast and from the Northern Plains
into the upper Great Lakes, but remain below average from the Southern
Plains into the Northeast.  Warmer than average temperatures expected
again across the Southeast into Florida on Saturday.
