...Winter storm expected to bring potentially heavy snow from portions of
the Southeast to the southern Mid-Atlantic...
...Heavy rain and mountain snow expected for central and northern
California...
...Winter storm expected to bring snow and ice accumulations to portions
of the Pacific Northwest...
A developing low pressure system in the northern Gulf of Mexico is
expected to bring a range of precipitation types from the lower
Mississippi valley to the southern Mid-Atlantic region today into
Saturday. A cold air mass in place will allow for a snow to fall today
from portions of the southern plains and lower Mississippi valley east to
the foothills of the southern Appalachians and the Piedmont of the
Carolinas. Tonight, snow is expected to spread north across portions of
the southern Mid-Atlantic region. Heavy snow is possible for some areas.
Sleet or freezing rain is also possible in the transition zone from snow
to rain across portions of the Southeast. Please refer to products issued
by local NWS forecast offices for details specific to your area. As this
low pressure system moves away from the East Coast into the north Atlantic
by Saturday afternoon, cold air is expected to linger across areas from
the southern plains to the Mid-Atlantic, with afternoon high temperatures
10 to 20 degrees below average.
The western U.S. will start off the forecast period relatively quiet, with
high pressure keeping most areas dry. By late Friday night into early
Saturday morning, however, a Pacific frontal system will rapidly spread
moisture back into the West Coast. Widespread and potentially heavy rain
is expected for much of central and northern California, with heavy snow
in the mountains. Farther north, cold air in place across the Northwest
will create the potential for snow and ice accumulations across much of
Oregon and Washington. Rain and snow will continue for the West Coast
Saturday night and Sunday, with precipitation also spreading into the
Great Basin, northern Intermountain West, and portions of the northern
Rockies. Along the West Coast, snow levels will gradually rise, with all
but the highest elevations of the Sierras changing to rain by Sunday
morning. Lingering cold air in the interior valleys of Oregon and
Washington will continue the potential for snow and freezing rain for
those areas.
