.SYNOPSIS...A brief break from the winds today will be followed by
north winds returning over the weekend as disturbances dive down
from western Canada bringing a cooling trend through early next
week. The strongest winds are expected to be focused near the lower
Colorado River Valley. By the middle of next week, a low pressure
system spins up off the Southern California Coast and moves inland
with limited moisture.
&&

.SHORT TERM...Today through Sunday.

A calm and sunny day is shaping up across the region today, even
along the lower Colorado River Valley, as north winds diminish under
a ridge of high pressure nosing inland from the eastern Pacific
across the Great Basin and northern Intermountain Region. North
winds will ramp up again Saturday due to a low pressure system
diving down from the northwest and carving out a broad trough over
the western states which will usher down additional disturbances out
of western Canada Sunday. Widespread gusts of 25 to 35 mph can be
expected each day and typical funneling down the lower Colorado
River Valley will lead to gusts near 40 mph around Laughlin-Bullhead
City to Mohave Valley. High temperatures will be near normal
Saturday then decrease several degrees Sunday as cooler air spreads
down from the north.

.LONG TERM...Monday through next Friday.

The weather pattern begins to change Monday and Tuesday as the
trough that developed over the western states during the weekend
retrogrades off the Southern California Coast and spins into a cut-
off low. Model ensembles have been showing this trend for several
runs and ensemble clusters indicate this system will slowly move
inland Wednesday through Friday, but with limited moisture and
dynamic forcing. For now, the sensible weather forecast does not
indicate anything significant as north-northeast breezes persist
early in the week then winds become lighter Wednesday through Friday
and temperatures slowly return to near normal as the system moves
inland and weakens. The NBM has 15-20 percent chances of
precipitation by Thursday over the mountains of southern Nevada and
northwestern Arizona. However, confidence is low in the evolution of
the system and on the potential to pull up subtropical moisture
south of the Baja Peninsula. We won`t get our hopes up for a
significant precipitation event, but we will continue to keep an eye
on it.

.AVIATION...For Harry Reid...Northeast to occasional east winds are
expected through the remainder of the overnight period. Speeds will
generally remain around 7-10 knots. Winds are then forecast to shift
back to the northwest after 12z with speeds remaining around 8 knots
or less. These northwest winds are forecast to continue through 18z
before shifting to the southeast through the afternoon, although
wind speeds will generally remain less than 7 knots. VFR conditions
with mostly clear skies will prevail, with only a few high clouds
with bases round 25kft expected toward the end of the period.

For the rest of southern Nevada, northwest Arizona and southeast
California...With the exception of KIFP and KEED, winds will be much
lighter across the region today. Winds will still remain northwest
through northeast for most areas, but wind speeds are expected to
remain below 10 knots. It`s possible that some locations could see a
brief gust over 10 knots, but overall they will remain short lived.
KEED and KIFP will continue to see northerly gusts through this
afternoon with KEED between 10-20 knots with occasional gusts up to
25 knots. KIFP will be slightly higher with speeds generally between
15-25 knots. Winds at KEED and KIFP will diminish after sunset and
be less than 10 knots overnight. Otherwise, VFR conditions with
clear skies will prevail.

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