...Lake-effect snow will linger across the Great Lakes with snow
squalls possible over interior New England as periods of mountain
snow blanket portions of the Rockies/High Plains and Pacific
Northwest...

...Moderate to heavy rainfall expected along the Gulf Coast the
next couple days with an isolated risk for flash flooding...

...A surge of arctic air is forecast to challenge low temperature
records across the Midwest on Thursday and across the northern
Mid-Atlantic to southern New England on Friday...

...Light snow could reach the central Appalachians to the
Mid-Atlantic on Friday with showers and embedded thunderstorms
down into the Southeast...

A fast-moving wintry weather pattern is forecast to prevail across
the northern tier states through the next few days.  Starting from
the western U.S., snow ahead of a digging upper-level trough has
continued to persist across the central Rockies into the High
Plains of Colorado where Winter Storm Warnings and Winter Weather
Advisories remain in effect.  The snow is forecast to drift
southward into northern portion of New Mexico tonight before it
gradually tapers off on Thursday as the upper trough exits the
southern Rockies into the southern Plains.  Mountain locations can
expect snowfall totals of 6-12", locally higher, with totals range
from 3 to 6 inches for lower elevations along the Colorado Front
Range.  The back end of the snow is forecast to reach the
panhandle of Texas Thursday morning before ending Thursday
afternoon.

Across the Pacific Northwest, the next system from the Pacific
will begin to spread mountain snow into the interior Pacific
Northwest into the northern Rockies on Thursday.  By Friday, the
snow will likely blanket the northern Rockies early in the day
before entering the central Rockies as the day progresses where as
much as a foot of new snow is possible by evening.  Meanwhile,
closer to coast across the Pacific Northwest including much of the
Cascades and lower elevations of the interior sections, periods of
rain can be expected for much of Thursday and Friday.

To the north, an initial surge of polar air behind a clipper-like
system has initiated lake-effect snow across the upper Great
Lakes.  As the associated cold front sweep across the remainder of
the Great Lakes tonight and into New England by Thursday,
lake-effect snow will overspread the lower Great Lakes along with
the possibility of snow squalls across interior New England on
Thursday.  Blustery and colder conditions will follow across much
of the Northeast Thursday night into Friday.  This surge of arctic
air is forecast to bring temperatures cold enough to challenge low
temperature records across the Midwest on Thursday and then across
the northern Mid-Atlantic to southern New England on Friday.

As a high pressure system associated with the arctic air invades
the northern and central U.S., the aforementioned upper-level
trough will emerge into the southern Plains on Thursday and will
begin to interact with a front near the Gulf Coast.  This weather
pattern will increase the chance of moderate to heavy rain with
embedded thunderstorms for the western and central Gulf Coast on
Thursday, spreading into the eastern Gulf Coast and across the
Southeast on Friday.  The rain and thunderstorms are in response
to a low pressure wave forming along the front.  In addition,
there is enough cold air farther north to support snow across the
central Appalachians to the Mid-Atlantic on Friday.  Nevertheless,
there is uncertainty on the northern extent and amount of the
snow.  Interests should keep abreast of further forecast updates
on the winter weather prospects for this region.
