...Energetic storm system to bring heavy rain and snow to much of the
western U.S...

eastern U.S...
...Above average temperatures expected for much of the central and eastern
U.S...
Precipitation across the West will become increasingly widespread today as
an a low pressure pressure pushes inland. Rain is expected across much of
California, with snow in the Sierras - the coastal areas may have periods
of heavy rainfall, as well as, the higher elevations of California, the
Pacific Northwest and the Intermountain West may have heavy snow. The
extent of the heavy snow will spread across much of the Rockies and the
adjacent northern Plains on Saturday as the system moves east. Snow levels
will lower as the upper-level trough moves inland, and snow is expected to
eventually fall at all but the lowest valley elevations. A vast majority
of the counties from central Washington/Oregon to Minnesota/Wisconsin have
winter weather advisories, winter storm watches and blizzard watches in
effect. Holiday travel will likely be adversely impacted by this system -
travelers are strongly encouraged to stay tuned to weather updates, allow
extra time to arrive safely or consider alternative routes.
Light snow and freezing rain will be possible across portions of the
central U.S. today as a fast-moving surface front passes through. Warm,
moist air will stream northward from the Gulf and will aid in increasing
rain amounts from the lower Mississippi Valley to the Tennessee and Ohio
Valleys. A few thunderstorms will be possible across the lower Mississippi
valley, where more unstable air will be in place. Cold air sinking into
the Great Lakes area will reinforce the snow generation from the Upper
Midwest to portions of the Northeast.
Mild temperatures are forecast for much of the central and eastern states
though Saturday. Some locations are expected to have maximum temperatures
to be 5 to 15 degrees above average. However, forecast highs will steadily
fall across the West as cold air filters in behind the frontal passage.
Many locations will 5 to 15 degrees below average along the West Coast, as
well as across the Great Basin, Intermountain West, and portions of the
Southwest.
