...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.
