.DISCUSSION...Today through Saturday.

The northwest flow aloft continues through the forecast period.
Today and Monday, this northwest flow will allow for the passage of
a shortwave trough, which will drop temperatures by 4 to 6 degrees
between this afternoon and Monday afternoon and will increase
northerly afternoon breezes (10-20 mph areawide, with 25-35 mph in
the Colorado River Valley) Monday afternoon. There is a 30% chance
of an isolated gust at or above 40 mph near Laughlin-Bullhead City,
but those speeds are not expected to be widespread in space or time,
so no wind-related headline is necessary. These northerly winds will
result in wave heights in excess of 2 feet on Lake Mohave,
particularly near Katherine Landing, which will result in hazardous
boating conditions for small craft. As mentioned in the previous
forecast discussion, Tuesday morning will be the coolest point in
the forecast period, with an 80% chance of freezing temperatures in
lower elevations of eastern Inyo County (particularly near Shoshone-
Tecopa); as such, issued a Freeze Watch from 1am through 8am Tuesday
morning marking their first freeze of the season. Other areas to
consider include the lower elevations of the Mojave National
Preserve and lower elevations of southern Mohave County, where there
exists a 30-40% chance of reaching freezing temperatures Tuesday
morning. No freeze headline issued for these zones at this time, but
will continue to assess with future shifts.

Another shortwave will drop through the southern Great Basin and
Mojave Desert on Wednesday. The current trajectory indicates that
the system will pick up meager amounts of moisture, which will
increase cloud cover and relative humidity across the region.
Precipitation chances have decreased areawide, with slight chances
of measurable rainfall (10-20%) confined to the higher elevations of
the southern Great Basin. Accumulations, if any, will be negligible.
Expect a return of gusty north winds (15-25 mph) Wednesday and
Thursday as the associated cold front passes through the forecast
area. Temperatures moderate heading into next weekend.

.AVIATION...For Harry Reid...For the 12Z Forecast Package...Winds
will be light and somewhat variable through late this evening,
with speeds expected to remain under 8KT. Overnight, winds settle
out of the north, increasing to 8-10KT prior to daybreak,
persisting thereafter. VFR conditions prevail, with increasing
mid- and upper level clouds between 15-20kft this morning that
will persist through the day before gradually scattering out
overnight.


For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package...Winds today will follow
diurnal directional patterns with some variability, with speeds
around 5-10KT. Exceptions include the northern Owens Valley, where
gusty north-northwesterly winds are expected this afternoon
through late evening, and locations across the western Mojave
Desert where westerly winds will gust to around 25KT this
afternoon through sunset. Overnight, winds shift to the
north/northwest, with elevated and intermittently gusty winds
expected through terrain favored areas of the northwestern Vegas
Valley and the Lower Colorado River Valley tonight through the end
of the period. Otherwise, VFR conditions prevail with bands of
mid- and high clouds around 15-20kft the next 24 hours.

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report
