.DISCUSSION...through Monday.

Weak shortwave dropping south through northern Nevada/Utah will
continue to push south through the day. There isn`t a lot of
moisture associated with this shortwave, but a few light showers
will be possible overnight and early Wednesday morning right along
the leading edge of the shortwave. A webcam in Lee Canyon was
indicating some light snow, but accumulations are not expected. As
the shortwave continues to drop south additional light showers will
develop today across the higher elevations of eastern Lincoln and
northern Mohave counties. Again, no accumulations are expected. The
biggest impact from this shortwave will be the increasing north
winds. Most areas will see winds 15 to 25 mph with a few gusts
approaching 30 mph. The strongest winds will be located down the
lower Colorado River Valley where a Wind Advisory has been issued
for Lake Mead and Lake Mohave due to 15 to 25 mph sustained
northerly winds gusting up to 35 mph this afternoon. These winds
will have the potential to result in 1 to 3 foot waves on the lakes,
making for hazardous boating conditions for small watercraft. Along
with the gusty winds, temperatures will also drop a few degrees with
below normal readings expected today and Thursday.

Once this shortwave pushes out of the area, we will start to see
ridging pushing in from the Pacific allowing temperatures to rise to
above normal readings by this weekend and early next week. Winds
will generally remain light across the area, but occasional breezy
north winds will occur down the lower Colorado River Valley
impacting mainly Lake Mohave. Dry conditions are also expected into
the middle part of next week.

.AVIATION...For Harry Reid...For the 12Z Forecast Package...Winds
will shift out of the north-northwest after sunrise, with speeds
increasing to 10-15KT by mid morning. Intermittent higher gusts
are expected, though expect these gusts to remain under 25KT
through early to mid afternoon. Gusts gradually diminish through
the afternoon as winds veer slightly to the northeast, remaining
elevated. After sunset, winds back to the north-northwest, with
sustained speeds dropping under 10KT and continuing through
Thursday morning. FEW-SCT clouds around 7-9kft early this morning
will improve through daybreak, with FEW-SCT clouds around 10-12kft
expected through the afternoon with skies gradually clearing
thereafter.


For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package...Elevated and at least
intermittently gusty northerly winds are expected across the
region this morning into this afternoon, with gusts to 20-25KT
common. Stronger gusts are expected through the Lower Colorado
River Valley, especially in the vicinity of IFP where gusts will
approach 30KT. This afternoon into this evening, gusts will
diminish, with northerly to northwesterly winds persisting
thereafter. Exceptions include the Owens Valley, where west-
northwesterly winds are expected overnight, and the western Mojave
Desert, where winds become light and variable late afternoon.
Bands of mid and high clouds will shift from north to south, with
bases around 10-20kft, clearing through this evening.
