.KEY MESSAGES...

* Northwest flow aloft will continue to bring periods of north
  winds and cooler temperatures to the region through the week.

&&


.DISCUSSION...Today through Sunday.

Shortwave pushing through the region will bring gusty north winds to
the region, with speeds generally between 10 and 20 mph. The
exception is the lower Colorado River Valley, where topographic
enhancement will allow for speeds between 25 and 35 mph, resulting
in wave heights greater than 2 feet on Lake Mohave. Cannot rule out
an occasional gust at or in excess of 40 mph, but these are not
expected to be widespread in space or time, so no wind-related
headline issued. Decreasing wind speeds and clearing skies will
allow for desert valleys to cool off tonight into Tuesday morning.
As a result, Freeze Warnings are in effect for the lower elevations
of eastern Inyo County (Death Valley National Park, Shoshone,
Tecopa), northeastern Clark County (Moapa, Mesquite, Bunkerville,
Overton), and central and southern Mohave County (Kingman, Hualapai
Valley) to mark their first freeze of the season. Another shortwave
will drop through the southern Great Basin and Mojave Desert on
Wednesday, increasing cloud cover and relative humidity across the
region. Expect a return of gusty north winds (15-25 mph) Wednesday
and Thursday as the associated cold front passes through the
forecast area. Temperatures will gradually increase late-week into
the weekend, reaching above-normal values by Friday.

.AVIATION...For Harry Reid...For the 06Z Forecast Package...Still
anticipating a shift from light and variable to northerly winds late
tonight as a weak cold front slides through. Speeds should be
strongest during the morning hours, with 50-70% chances of 10+ knots
from 12z-20z. Winds weaken slightly during the afternoon hours, but
retain the north-northeast direction. After sunset, winds become
light and flip to the southwest. Few to scattered clouds at or above
15kft.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...A cold front and
associated northerly winds continues to push south tonight, with
northerly or northeasterly breezes encompassing the majority of the
area by daybreak Monday. Gusts of 15-25 knots possible at most
locations, with 25-35 knots expected in the lower Colorado River
Valley. VFR conditions persist with clouds at or above 15kft.

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