.DISCUSSION...through Saturday.

Peak wind gusts yesterday were generally in the 25 to 40 mph range
for most locations, and between 40 and 50 mph in western San
Bernardino County. A compact low pressure system will drop south
into the Great Basin today, bringing even stronger winds, blowing
dust, and cooler temperatures to the region. Southwesterly winds
will pick up across the region later today and shift from the
southwest to the northwest as a cold front moves through. The front
passes through Nye, Esmeralda, and Inyo counties during the
afternoon, reaches Las Vegas and the I-15 corridor in the evening,
and finally the Colorado River Valley later overnight. Expect
widespread gusts between 40 and 55 mph as well as stronger gusts in
excess of 60 mph in parts of southern Nevada and southeastern
California. A series of Wind Advisories and High Wind Warnings go
into effect later today and remain in effect through the night.
Drivers should be prepared for hazardous crosswinds and blowing
dust, and boaters should be aware of waves between 2 and 4 feet on
Lake Mead, Lake Mohave, and Lake Havasu. Gusty winds will weaken by
tomorrow afternoon. Precipitation chances with this system are
limited to eastern Lincoln County in the afternoon and evening with
POPs between 50 and 80 percent, favoring high terrain. Temperatures
decrease 10 to 15 degrees between today and tomorrow, with highs in
the upper 70s expected for Las Vegas. After tomorrow, high pressure
rebuilds and temperatures increase through the end of the week.

.AVIATION...For Harry Reid...For the 06Z Forecast Package...
Breezy southwest winds will continue through around 08z to 10z
Sunday. Winds will then remain 10 knots or less much of the
overnight before a rapid increase during the late morning and
early afternoon. South to southwest winds of 20-25 knots can be
expected after 18z, with gusts of 30 to 40 knots. Winds will
quickly shift to the north by 02z to 03z in the wake of a powerful
cold front. This will result in a period of even stronger wind
gusts up to 40-45 knots. Winds will remain elevated beyond 06z
Monday, but the potential for gusts in excess of 40 knots will
gradually diminish overnight. Otherwise a few mid and high clouds
can be expected.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...The main impact to
aviation will be a round of gusty winds beginning Sunday afternoon
and continuing into early Monday. For all terminals outside of
KBIH, expect gusty west to southwest winds to develop by 16z to
18z with gusts in the 25 to 35 knot range. Winds will shift to the
northwest behind a surging cold front moving from north to south
across the region. Winds in the wake of the front will increase to
20-30 knots with gusts of 40 knots to perhaps 50 knots. Winds
will remain elevated beyond 00z to 06z, especially at KIFP/KEED
with strong winds will last into Monday morning. For KBIH, winds
will generally remain north to northwest. A brief lull in wind
speeds will occur by 08z to 10z this morning, but will rapidly
increase behind the front by 18z-20z Sunday. Aside from winds, mid
and high cloudiness will move across the region in association
with the front.
