...Frigid airmass brings sharply colder weather across the eastern
two-thirds of the country and record low temperatures through the
Southeast including all of Florida by Tuesday morning...

...Snowy, very cold and windy from the Great Lakes to interior New England
and west slopes of central Appalachians...

...Critical fire weather across southern Texas into tonight...

An unusually strong surge of polar air is well under way into the
mid-section of the country this Sunday afternoon.  This polar plunge will
be in stark contrast with the increasingly mild conditions across the West
and across the East for the remainder of today.  The strong temperature
contrast between the cold in the central and the warmth in eastern U.S.
will work in concert with a deepening upper-level trough to intensify a
low pressure system which will progressively move through the Northeast on
Monday.  A swath of wet snow is forecast to follow the northern edge of
the low pressure system as far north as northern Maine this evening, and
as far south as the western slopes of the central Appalachians into the
Ohio Valley beginning this evening and lasting into much of Monday.  Total
snow accumulations as much as 6 to locally 12 inches are possible across
east-central West Virginia.  Meanwhile, a cold rain across the lower Great
Lakes should change over to periods of lake-effect snow tonight and
continue through Monday as colder air arrives behind the low pressure
system.  Areas near the southern shore of Lake Michigan including the
lake-front region of Chicago could be impacted by a period of locally
enhanced snowfall tonight when a smaller scale low pressure system could
form over the relatively warm Lake Michigan.  By early Tuesday, much
milder air coming from the northern Plains should change the snow to rain
near Lake Michigan before ending, and possibly change the lake-effect snow
to rain near the shores of the Lake Eire and Lake Ontario.

Along the East Coast, broad southerly flow ahead of the intensifying low
pressure system has brought anomalous warmth into the 70s as far north as
Virginia Sunday afternoon.  The best chance of showers and thunderstorms
is expected across the southern half of New England into tonight.  A sharp
cold front is sweeping through the East Coast and then out into the
Atlantic tonight with only passing showers and some embedded thunderstorms
up and down the East Coast.  This will be followed by sharply falling
temperatures and increasingly blustery winds from the west on Monday. 
High temperatures will struggle to reach the freezing mark on Monday along
the central and central Appalachians while below freezing temperatures are
forecast to reach deep into the South by Monday morning.  By Tuesday
morning, record low temperatures will be common across the entire
Southeast including all of Florida where below freezing readings are
forecast along the eastern Gulf Coast and as far south as northern
Florida.  Freeze Watches and Warnings are in effect for many areas from
the southern Plains through the Deep South, Southeast and into the
Mid-Atlantic, and as far south as northern Florida.

In the West, an upper ridge will be amplifying as the polar plunge occurs
in the central and eastern U.S.  The upper ridge will expand the
unseasonably warm temperatures into the northern High Plains by Monday. 
Meanwhile, increasing winds and dry conditions behind the cold front are
forecast to support critical fire weather conditions into tonight for
portions of southern Texas under gusty winds per the Storm Prediction
Center.  In addition, Red flag warnings are in effect across southern
Texas into southwestern Louisiana.  Across the Pacific Northwest, rain
associated with the next frontal system from the Pacific is forecast to
arrive later tonight, spreading into far northern Rockies on Monday. 
Meanwhile, the anomalous warmth in the West is forecast to reach into much
of the High Plains and up across the central and northern Plains on
Tuesday behind a warm front.
