.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 18Z Forecast Package...20 to 30
knot northerly wind gusts will persist through later this afternoon
when gusts will decrease and winds will become more north-
northeasterly. These 10 to 15 knot sustained north-northeastelry
winds will continue into the evening hours when winds will decrease
in magnitude and shift back to a more north-northwesterly direction.
Northeasterly winds will return again on late Thursday morning. VFR
conditions will persist with FEW mid-clouds AOA 10 kft through the
afternoon.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 18Z Forecast Package...20 to 30 knot
northerly wind gusts will continue across southern Nevada,
northwestern Arizona, and down the Colorado River Valley through
later this afternoon. Northerly wind gusts will continue to impact
southeastern California, but will be in the 15 to 25 knot range.
With the exception of IFP where winds will remain elevated
overnight with intermittent gusts, wind gusts will drop off across
the region during the early evenings. Winds will tend to favor a
northerly direction through the overnight hours, but may become
more variable at times. VFR conditions will prevail through the
TAF period with bands of mid and high clouds AOA 10 kft moving
from north to south, clearing through this evening.
