.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 00Z Forecast Package...Breezy
southwesterly winds are expected through the evening hours with
gusts of 20-25 knots expected. A brief lull in the winds is
expected overnight but some sporadic pulses of stronger southerly
winds exceeding 10 knots will remain possible overnight.
Southwesterly winds will return Monday with gusts of 25 to 30
knots expected through the afternoon. Winds will shift to westerly
or northwesterly directions after dark as a weak cold front drags
across the area. Aside from SCT-BKN high clouds, no operationally
significant cloud cover is expected.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 00Z Forecast Package...Westerly to
southwesterly winds will persist in the eastern Sierra and Western
Mojave Desert through the afternoon hours, with gusts between 20
and 30 knots. At KBIH, there is a 40 percent chance for gusts over
30 knots between 22Z and 00Z. Overall, gusts areawide should
diminish in the evening. Gusty winds are not expected in the
Colorado River Valley, where wind speeds should remain less than
10 knots. SCT to BKN mid and high clouds will continue to stream
through the area. Similar conditions will resume on Monday though
winds around KBIH will swing around to the northwest behind a cold
front moving through in the morning.
