...East Coast holiday travel disruptions likely Tuesday night into
Wednesday.  Much better travel conditions across much of the remainder of
the nation...

...A white Thanksgiving on tap for portions of Northern New York State,
Northern New England and the Northern Rockies...

...Much colder temperatures sink southward into the Northern
Plains/Northern Rockies on Thanksgiving...


The widespread precipitation event currently ongoing across the eastern
quarter of the nation will continue to have potential holiday travel
impacts Tuesday night into Wednesday as the storm system and frontal
boundaries responsible for the inclement weather continue to push
eastward.  Widespread heavy rains are likely from Tuesday afternoon into
Wednesday across the east, bringing some much needed rains to to areas
from the Appalachians, Southeast, Mid-Atlantic and Northeast that have had
much below average precipitation over the past several weeks.  On the
northern edge of this area of heavy precipitation, a white Thanksgiving is
possible as accumulating snows are likely from northern New York State
into northern New England, with the heaviest accumulations in excess of 6"
possible from central to northern New Hampshire into northern Maine.

Overall travel conditions will improve significantly by Thanksgiving
across nearly all of the nation.  Exceptions to this will be over the
Northern Rockies and Northern High Plains where accumulating snows are
possible beginning early Thursday and continuing into Thanksgiving day and
along the coastal Pacific Northwest Wednesday and across far South Texas
early Thursday, where light precipitation amounts are possible.  Areas of
the Northern Rockies and Northern Plains will also see much colder
temperatures on Thanksgiving day as cold air from southern Canada surges
southward.  Temperatures are expected to be much above average across this
region Tuesday and Wednesday, followed by much colder temperatures and the
above mentioned snow threat for Thanksgiving Day. This colder than average
air will continue to sink southward at the end of the week into this
weekend across the Central Rockies and into the Central to Southern
Plains.  Cooler than average temperatures also likely across the southeast
quarter of the nation on Thanksgiving, with these cooler than average
temperatures then taking hold across much of the nation by this weekend,
save for the immediate West coast and South Florida. 

Happy Thanksgiving!
