.SYNOPSIS...Gusty southwesterly winds will continue through the
afternoon and into the evening as a low pressure system moves into
the area. Isolated showers will accompany this system, with a
dusting of snow possible in the mountains of the southern Great
Basin and modest snow accumulations in the Eastern Sierra.
Temperatures will remain below normal through the weekend before
warming back up to above normal next week as high pressure
rebuilds over the region.
&&


.SHORT TERM...Today and Tomorrow.

The cut-off low off, currently churning off the coast of central
California, will continue its eastward progression, moving through
the Desert Southwest over the next few days. As this low pushes into
the area today we will see gusty southwesterly winds continue
through the day. A Wind Advisory remains in effect for Death Valley,
the western Mojave Desert, and the Morongo Basin through 11:00 pm
this evening. While winds will not be as strong over Lake Mead and
Lake Mohave, we will see 20 to 25 mph sustained southerly winds
produce 1 to 3 foot waves this afternoon. These winds and waves will
make for hazardous boating conditions for small water craft. As
such, a Lake Wind Advisory has been issued from noon to 8:00 pm this
evening.

Outside of gusty winds, this system will also bring increased
chances for isolated showers to the southern Great Basin, mountains
of southern Nevada, and the western portions of San Bernardino and
Inyo counties. Given the cold temperatures aloft (-25 to -30 degrees
Celsius at 500 mb) and the dynamic forcing associated with this
system it is possible that some of these showers are more convective
in nature, producing lightning. Snow levels will drop to 5,000 to
6,000 feet with this system, with minor accumulations possible in
the mountains of the southern Great Basin. A Winter Weather Advisory
will go into effect for the Eastern Sierra beginning at 7:00 am PDT
this morning and continuing through 11:00 am PDT tomorrow.
Elevations between 6,000 and 8,000 feet in the Eastern Sierra will
see somewhere between 3 to 6 inches of snow with locally higher
totals in the Sierra crest.

This system will also bring cooler than normal temperature to the
region with temperatures dropping around 7 to 12 degrees from
yesterday to today. These cooler than normal temperatures will stick
around on Sunday as the trough remains overhead. While Sunday will
be cooler, we will see winds settle down with light showery activity
continuing across the southern Great Basin.

.LONG TERM...Monday through Friday.

The trough axis remains over the southwestern United States on
Monday, helping to maintain near average temperatures for this time
of year. Afterwards, the trough moves east and high pressure builds
Tuesday onwards. This pattern change will send highs back into above
normal territory with highs 5 to 10 degrees above normal by Thursday
and Friday. This includes highs in the upper 80s for Las Vegas and
in the 90s for the Colorado River Valley. Other than increasing
temperatures, light winds and dry conditions are expected.
