.KEY MESSAGES...

* Today will be the warmest day of the upcoming week as a low
  pressure system brings slightly cooler temperatures and breezy
  conditions to start the week.

* An additional low pressure system may bring another round of gusty
  winds and cooler temperatures later in the week.

.DISCUSSION...through next weekend.

Temperatures will peak across the region today as high pressure
ridging begins to shift east and southwesterly flow aloft takes
hold ahead of a weak shortwave. Regional temperatures are already
running 1-4 degrees above their values at this time yesterday, and
anticipate one more round of some record high temperatures before
cooling commences tomorrow. Todays temperatures will also benefit
from some enhanced mixing thanks to increasing southwesterly
surface winds that will continue to expand through the afternoon
hours.

Winds will continue to increase along the ridgelines tonight and
some locally gusty conditions are likely overnight in the Spring
Mountains. Meanwhile, the brunt of the strongest winds will occur
Monday with fairly widespread 25-35 mph afternoon wind gusts
expected across the region, with the strongest winds gusting over
40 mph favored near the Barstow area. Gradual cooling will also
begin as heights begin to decline, though temperatures will remain
above normal. A brief shortwave ridge builds in on Wednesday only
to be followed by a stronger trough dropping south out of the
PacNW Thursday that eventually forms a cut off low and drops into
the Baja region. There remains some uncertainty in how this will
evolve but another round of gusty winds and temperatures trending
closer to normal are expected.

.AVIATION...For Harry Reid...For the 06Z Forecast
Package...South winds are expected overnight. Captured the impactful
winds in the TAF overnight period with winds speeds at or above 10KT
and gusts up to 20KT, however this may be intermittent with lulls in
the winds at times through Monday morning. After sunrise, winds will
increase out of the southwest. Gusts over 25KT are likely late
morning through the afternoon. Gusts will end around sunset but
continued southwest elevated winds are expected Monday evening.
Winds will become northwest around 10KT early Monday night, between
03Z and 06Z. A few gusts are possible when the winds become
northwest but would be short lived. VFR conditions with SCT-BKN
clouds at or above 15kft are expected at times through Monday
evening then clear skies will return.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...After a period of
lighter winds tonight, gusty west to southwest winds are expected
across much of southeast California through far southern Nevada into
Western Arizona on Monday. Widespread gusts of 20-30KT are expected
Monday afternoon, with higher gusts up to 35KT in the Western Mojave
Desert. Further north and west, winds will become north to northwest
in Inyo County and the Southern Great Basin as a front moves through
with gusts to around 20KT. Winds will diminish in the evening, then
become northwest overnight as the front continues to shift south.
SCT to BKN mid and high clouds will persist tonight and early Monday
before clearing Monday evening area-wide.
