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.
