...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...

A deep longwave trough over the West will funnel in moisture over parts of
the Pacific Northwest, Great Basin and the Rockies, with possible
localized heavy snow over higher terrain, while lower elevations may
experience some light snow showers through the remainder of today. Heading
into Monday, the trough continues to advance eastward, the system will
become more widespread with chances of precipiation over the Central
Plains into the Mississippi Valley. Precipitation will range between
showers and thunderstorms over Texas and parts of the Southeast, as the
system merges with moisture from the Gulf. Weather Prediction Center has
highlighted a Marginal Risk (level 1/4) for Excessive Rainfall for parts
of the Gulf Coast and Deep South. Meanwhile further north, expect a wintry
mix and snow over the lower parts of the Midwest/Great Lakes, Central
Plains, Mississippi Valley, and Ohio Valley where the moisture will
intertwine with colder air mass by Monday evening. Over the Upper
Midwest/Great Lakes, lake-effect may increase chances of heavier snowfall.
Therefore, several regions continue to issue Winter Weather Advisories,
especially over the Upper Midwest and Upper Great Lakes. 

The frontal system that brought much of the heavy snow over the northern
portions of CONUS, will gradually move into southeastern Canada today,
tapering off the heavy snow with some possible lingering snow over areas
over the Great Lakes that experience lake-effect. As the surface low
deepens and the frontal system moves northeastward, expect possible
widespread showers/thunderstorms along parts of the Mid-Atlantic and East
Coast Monday through Tuesday. The deepening low, will gradually move
towards New England, aiding in wintry precipiation Monday into Tuesday,
especially for higher elevations. Chances for snow will be higher over
parts of the Appalachians, the interior parts of New England, and northern
Mid-Atlantic. South of the heavy snow, over the Central and Southern
Appalachians, there are chances for light to moderate freezing rain and
icing over the higher terrain.

As the upper-wave moves eastward and the surface cold front moves through
the region, temperatures over the Northern Plains, Upper Midwest and
Interior Northeast will see below normal temperatures, with a 12-25 degree
difference. Some areas over north-central U.S. can see high temperatures
within the teens 20s. 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 Monday mainly in the 20s to 40s. 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. Heading into Tuesday, the central Plains begin to see
near normal temperatures.
