...Heavy snow possible from portions of the northern plains and Midwest to
the Northeast...
...Heavy snow possible for the Cascades and portions of the Rockies and
Intermountain West...
...Another round of cold air expected to move into the northern plains and
Upper Midwest...
A low pressure system over the central U.S. this morning will spread snow
across areas from the northern plains to the Northeast today and tonight.
Heavy snow is possible for some areas. Farther south, a mix of wintry
precipitation including snow, sleet, freezing rain, and rain is possible
from portions of the Ohio valley east into the Mid-Atlantic region today
and tonight. Meanwhile, rain and a few thunderstorms are possible ahead of
the cold front from the lower Mississippi valley to the southern
Appalachians. On Monday, snow, sleet, and freezing rain will continue
across the Northeast during the morning, with rain farther south from the
Mid-Atlantic to the Southeast. The frontal system will move quickly east
during the day, with precipitation across the eastern U.S. becoming much
more scattered by Monday afternoon and evening. The front is expected to
linger from the lower Mississippi valley to the Southeast on Tuesday,
keeping scattered showers and storms a possibility.
A couple lingering frontal boundaries, and a series of upper-level
disturbances will keep the western U.S. unsettled through the short range.
Heavy snow is possible today and tonight across the Cascades as well as
across the higher elevations of the Intermountain West and Rockies. The
region will see somewhat of a lull in precipitation during the day on
Monday, although scattered areas of snow will remain, with rain showers
along the coast. Monday night in to Tuesday another Pacific storm system
will approach the coast, spreading rain and mountain snow into central and
northern California and southern Oregon.
Colder air will gradually move into the northern plains over the next
couple days as an area of arctic high pressure noses southward east of the
Rockies. Afternoon high temperatures across the northern plains today and
Monday are forecast to be 20 to 30 degrees below average. On Tuesday the
colder temperatures will spread east into the Upper Midwest as well, with
high temperatures expected to be 15 to 25 degrees below average.
