.KEY MESSAGES...

  Tuesday and Wednesday.

* Late-week, temperatures drop to near-normal, southwest winds
  increase, and elevated fire danger returns.

.DISCUSSION...Today through Monday.

Very isolated instances of showers and thunderstorms possible in far
southern San Bernardino and southern Mohave County today, but
otherwise, the region can expect mostly sunny skies. Afternoon
temperatures will peak today and Wednesday with widespread Moderate
Heat Risk (Level 2 of 4) and pockets of Major (Level 3 of 4) in the
desert valleys. This level of heat affects anyone without adequate
cooling and/or hydration, especially those in town from cooler
climates and those consuming alcohol, caffeine, or other drugs.

Late-week, temperatures will cool closer to seasonal normals and
wind gusts will increase from the southwest each afternoon as a
shortwave trough pushes into the California coast. Wind gust speeds
will elevate to 15 to 25 mph each afternoon Thursday through
Saturday, with greatest speeds Friday afternoon between 25 and 35
mph. While speeds are expected to remain sub-advisory on Friday, the
dry & windy conditions coupled with cured fuels will increase the
ease of wildfire starts and spreads. Activities involving flames or
sparks such as outdoor grilling and safe-and-sane fireworks are
strongly discouraged on days with elevated fire danger.

Southwesterly winds will continue through the forecast period,
with an expected lull from mid-morning through early afternoon
when winds become light and variable. Overnight, winds will remain
under 10KT, though elevated and at least intermittently gusty
winds will return from afternoon through late evening. Gusts up to
around 20KT are expected, with gusts diminishing overnight. VFR
conditions will continue, with no operationally significant cloud
cover expected as clouds remain at or above 12kft. Temperatures
will exceed 100F between 17Z-05Z, reaching a high of 109F.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package... Southerly to
southwesterly winds will generally be the rule the next 24 hours,
with wind speeds around 5-10KT tonight, becoming elevated and
gusty once again Tuesday afternoon through the evening. Gusts to
around 20KT are expected, with stronger westerly winds expected
across the western Mojave/KDAG where gusts will reach around 25KT,
and similar southwesterly gusts at KEED in the Colorado River
Valley through early evening. Another exception will be KBIH in
the northern Owens Valley, where winds generally follow diurnal
patterns, with speeds around 10KT or less through the forecast
period. Thunderstorms are possible during the afternoon and early
evening, mainly across portions of southeastern California and
