...Gusty winds to impact the Northeast and Mid-Atlantic tonight...

...Numerous showers and scattered thunderstorms forecast across the Deep
South on Tuesday and Southeast/Mid-Atlantic on Wednesday, with the
potential for light snow from the central Appalachians to the northern
Mid-Atlantic...

...Moderate to heavy snowfall overspreading the northern Great Basin and
northern Rockies tonight to eventually enter the central High Plains on
Wednesday...


A powerful cold front swinging through the eastern U.S. tonight will usher
in much colder temperatures to the region, as well as the potential for
gusty winds. Outside of of a few lingering showers along the East Coast
and moderate snowfall located over the northern tip of Maine, the most
widespread impacts into Tuesday morning will be associated with gusty
winds. Wind Advisories are in effect from the southern Appalachians to
southern New England. Gusts could approach 50 mph and lead to tree damage,
isolated power outages, and difficult driving conditions for high profile
vehicles.

Farther south, the aforementioned cold front is expected to stall across
the Southeast and Gulf Coast on Tuesday until a developing area of low
pressure moves along the frontal boundary and off the Mid-Atlantic coast
on Wednesday. As a result, lingering showers and isolated thunderstorms
will gradually increase in coverage on Tuesday afternoon throughout the
Deep South. By Wednesday, precipitation will spread north of the low
pressure system and into the northern Mid-Atlantic. Cold temperatures
aloft will allow for snow to fall across parts of the central
Appalachians, as well as northern Maryland, Pennsylvania, and parts of the
Northeast. Besides the highest terrain, most of the snow that falls after
sunrise will struggle to accumulate given surface temperatures around
freezing and the increasing March sun angle. Therefore, only a few inches
of accumulating snow on grassy surfaces is expected for this region. Much
needed rain is anticipated to continue throughout the Southeast on
Wednesday.

Shifting to the western U.S., a potent cold front diving southward out of
Canada will set the stage for widespread snowfall throughout the northern
Great Basin and northern Rockies tonight and Tuesday. Locally heavy snow
is possible across the tallest mountain peaks of Idaho and Montana. By
Wednesday, the cold front is forecast to sink into the central Great Basin
and central Rockies, which will also shift the axis of moderate snowfall
south as well. Additionally, a strengthening upper-level jet will allow
for locally heavy snow to extend into the central High Plains. Snowfall
totals over 6 inches are possible by the end of the event on Thursday from
southeast Wyoming to southern Nebraska and far northern Kansas. Heavy
snowfall more than a foot is also possible throughout the higher terrain
of northern Utah, Wyoming, and Colorado. Meanwhile, temperatures 20 to 30
degrees below average will also follow in the wake of the system across
the northern Plains into the middle of the week. Highs will struggle to
reach out of the teens and 20s, making it feel more like the middle of
winter.
