.KEY MESSAGES...
* Patchy fog will remain possible across parts of the Mojave
Desert this morning with locally reduced visibility.
* Heavy snow will return to the Sierra Saturday and Sunday with snow
totals exceeding a foot above 8500 feet.
* Unsettled weather will persist across the Western U.S. through the
week with periods of breezy conditions and additional rounds of
light rain and mountain snow.

.DISCUSSION...through next weekend.
Current satellite imagery shows low clouds over Mohave, Clark, and
Lincoln counties. Surface observations indicate temperatures within
a few degrees of dew points and surface visibilities under one mile
at Kingman. Given this conducive environment for fog development and
reports of low visibility, have issued a Dense Fog Advisory for
parts of Mohave County including Kingman through most of the
morning. High clouds over the remainder of the southern Great Basin
and southeastern California should hinder fog development in these
areas.
Light precipitation is on track to spread into the area today and
tomorrow as moisture advects in along southwesterly flow. Most of
this should be in the form of light rain and have little impact to
the area. The greater concern is heavier snow in the Sierra where
lift and moisture will be the greatest. Given the warm subtropical
nature of this moisture, snow levels will start off around 8000 feet
today, then lower to around 6500 feet by tomorrow as heights aloft
fall with the incoming low. Moderate to Major winter storm impacts
are expected in the Eastern Sierra including Aspendell and a Winter
Storm Warning remains in effect through early Monday morning.
Additional disturbances will move across the area through midweek. A
trough will drop into the western United States during the second
half of the week. This change should bring colder temperatures and
lower snow levels, although precipitation should remain fairly light
given the dry continental track of the system. Afterwards, dry
northwesterly flow takes hold by next weekend.

.AVIATION...For Harry Reid...For the 06Z Forecast Package...SCT low
clouds will persist into the early morning hours with some isolated
CIGs around 3kft possible at times. There remains a low probability
of fog and will leave it out of the current TAF, but some isolated
areas in lower spots can not be completely ruled out. Expect to see
mid and high level clouds increase after 09Z with SCT clouds around
12k feet which will continue to increase Saturday morning and become
BKN by afternoon. Winds will remain light and diurnal through the
TAF period. There will be an increase in shower chances late
Saturday afternoon, but should still remain isolated.
For the rest of southern Nevada, northwestern Arizona and
southeastern California...For the 06Z Forecast Package...FEW-SCT
clouds around 020-030kft will into the early morning hours along
with a few patchy areas of fog. At this time, fog does not look to
impact any TAF sites and will leave out of the TAF forecast.
Increasing mid and high level clouds overnight ahead of the next
system that will bring isolated to scattered showers to the region
Saturday afternoon. The rain/snow chances will remain highest in the
Sierra and Owens Valley Saturday where lower CIGS and visibility
reductions are likely. Winds will remain light and diurnal through
the TAF period.

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report
any significant weather or impacts according to standard operating
