...As one winter storm ends for the Midwest/Great Lakes, another potential
storm will follow quickly for New England and the Mid-Atlantic...

...Chilly temperatures continue across much of the eastern and central
U.S. in a winter-like pattern...

An active, winter-like pattern will continue over the next couple days
featuring winter storms bringing impactful winter weather and chilly
temperatures for much of the country. An upper-wave and accompanying
surface low pressure/frontal system bringing heavy snow to the region
yesterday (Saturday) and into the early morning hours today (Sunday) will
begin to move into southeastern Canada during the day with snow tapering
off across the region. Snowfall will linger longest for favorable
lake-effect zones downwind of the Great Lakes with a few more inches of
accumulations expected. Some precipitation will also spread into the
Mid-Atlantic/Northeast, with rain showers closer to the coast and a wintry
mix/snow inland, though any accumulations should remain limited to higher
elevations of interior New England. Additional showers and some
thunderstorms are also expected along the trailing cold front southwest
through the Appalachians/Tennessee Valley to the central and western Gulf
Coast, as well as along the coastal Southeast, with mostly light to
moderate rainfall expected.

To the west, another upper-wave currently dropping through the Great
Basin/Rockies will bring some locally heavy mountain snow to the Wasatch
in Utah and Rockies in Colorado today, with some lighter snow showers in
the surrounding lower elevations. Then, as this wave moves quickly
eastward, it will encourage moist return flow over the Plains and into the
Mississippi Valley with an expanding area of precipitation Monday.
Showers/thunderstorms will focus along the Gulf Coast and inland across
eastern Texas into the Southeast, with a transition into a wintry mix and
then snow further north over the central Plains and eastward into the
Midwest where colder air will be in place. An expanding swath of light to
moderate accumulating snow is expected later Monday and into the overnight
hours from central Kansas east through the Middle Mississippi Valley and
into the Ohio Valley/Lower Great Lakes. Some favorable lake-effect areas
could see enhanced locally heavier snowfall. The upper-wave will also help
to deepen/organize an area of low pressure along the frontal boundary
lingering on the Gulf Coast, expected to lift northeastward along the East
Coast overnight Monday. More widespread showers and thunderstorms are
expected throughout the Southeast, with some locally heavy rainfall and
isolated flash flooding possible. Further north, the combination of the
approaching upper-wave and coastal low lifting northward will help to
enhance wintry precipitation chances late Monday and into the day Tuesday
for New England southwest through the interior Mid-Atlantic and
central/southern Appalachians. Accumulating snow will be possible
especially inland from the coast for New England into the northern
Mid-Atlantic, with the potential for icing southwest along the
central/southern Appalachians. The timing, track, and strength of this
potential winter storm remain uncertain so keeping up-to-date with the
latest forecast is recommended.

Elsewhere, another upper-wave/frontal system will drop southward into the
Pacific Northwest/northern Rockies later Monday and into the overnight
hours, bringing lower elevation/coastal rain and interior/higher elevation
snow chances. Temperature-wise, much of the eastern/central U.S. will
remain well below average and chilly with broad upper-toughing in place
and repeated cold frontal passages. The latest cold front has brought the
coldest air of the season so far to the central/southern Plains east to
the Mid-South, with highs Sunday and Monday mainly in the 20s to 40s.
Further north, highs across the northern Plains into the Midwest will
mainly be in the teens and 20s. Conditions will be downright frigid along
the northern tier, with lows around 0 and wind chills below 0. To the
east, highs will be in the 30s and 40s for New England and the
Mid-Atlantic with 40s and 50s into the Southeast. The only areas to see
some reprieve from the cold will be along the Gulf Coast and southeast
Atlantic Coast as temperatures climb into the 60s and 70s on the south
side of the lingering frontal boundary.  Conditions will be around or a
bit above average in the West, with 40s for the interior, 50s and 60s
along the West Coast, and 60s and 70s into the Desert Southwest.
