Rockies...

The last in the current series of active storms affecting the
nation will be pushing eastward tonight from the Great Basin into
the Central Rockies, eastward across the Southern to Central
Plains toward the Middle Mississippi Valley/ Ohio Valley on
Wednesday and into the Northeast on Thanksgiving day.  Travel
disruptions are possible with this system as it moves steadily
eastward during the busy Wednesday & Thursday travel rush.  Heavy
snows will be concentrated primarily in the higher terrain of the
Great Basin and Central Rockies from the Wasatch of Utah into the
Rockies of Colorado.  As cold air sinks south in the lee of the
Central Rockies light snowfall amounts may push eastward in the
Central High Plains of Colorado and far western Kansas during
Wednesday.

This system will be primarily a rain producer on Wednesday from
portions of the Central Plains ,mid Mississippi Valley, Ohio
Valley and Southeast.  Rainfall totals of .25-.50"+ will be much
needed for drought stricken regions of the Southeast, while the
Ohio and Mid Mississippi Valley remain the few areas of the lower
48 not in drought, but will also see moderate rainfall amounts.
Much needed rains will also be spreading eastward on Thanksgiving
into the Mid Atlantic and the Northeast.  The Thanksgiving Day
parade in New York City likely to be wet and cold this year as
rain overspreads the Northeast early Thursday.  Across the
interior Northeast, accumulating snows are possible through the
higher terrain areas from the Poconos of Pennsylvania, the
Catskills and Adirondacks of New York,  Berkshires of western
Massachusetts, Green Mountains of Vermont and White Mountains of
New Hampshire.

While stormy weather presses eastward across the Central to
eastern U.S. over the next two days, tranquil and drier weather on
tap for the West coast.  This will bring an end to the recent very
active pattern of heavy lower elevation rains and higher elevation
heavy snows, with this tranquil pattern continuing through the
holiday weekend.  For much of the nation, the return trip from
Thanksgiving will have much better travel conditions than the
Wednesday to Thursday peak travel period.

Temperature wise, much above average temperatures likely from the
Southern Plains into the Gulf Coast on Wednesday, while much below
average temperatures expected from the Northern Plains into the
Central Rockies and Great Basin.  These cooler temperatures will
be pushing south and east on Thanksgiving across much of the mid
section of the nation and across the East by Friday.  Below
average temperatures also expected across much of the West over
the next few days, but a warming trend expected by the weekend.
