.KEY MESSAGES...

* Dangerous temperatures will continue through Monday across the
  Mojave Desert. Hotter than normal temperatures will continue
  through next week.

* Convective activity will be limited to northwestern Arizona over
  the weekend.

&&

.DISCUSSION...through Friday.

Dangerous heat will persist across the Mojave Desert into next week
as ridging remains in place. Widespread Major HeatRisk (Level 3 of
4) will continue across the Mojave Desert through Monday with
pockets of Extreme HeatRisk (Level 4 of 4) in lower elevations.
Temperatures will continue to run around 5 to 10 degrees above
normal, with little overnight relief in places like Death Valley and
Las Vegas where overnight low temperatures will be 100+ and 90+
degrees respectively. Temperatures will decrease a few degrees early
next week as the ridge shifts off to our east, but will quickly
rebound as the ridge retrogrades back west, eventually moving
directly overhead late next week.

Moisture will decrease slightly over the weekend as we find
ourselves under more southwesterly flow aloft. This relative
decrease in moisture combined with a lack of lifting outside of
daytime heating will result in lull in convective activity the
region over the weekend. The exception is far eastern Mohave County,
where there is a 10 to 15% chance of afternoon storms over the
weekend.

.AVIATION...For Harry Reid...For the 06Z Forecast
Package...All convection has ended near the valley this evening. No
additional thunderstorms are expected to develop near the terminals
through the TAF period. South winds will remain under 8KT overnight
with light and variable winds Saturday early morning. Much like the
past few days, south to southwest winds will increase after 18Z with
gusts up to 20KT expected through the afternoon. Winds will diminish
after sunset as light south to southwest set up for Saturday night
into Sunday morning. VFR skies with CIGs at or above 15kft.
Temperatures will exceed 100 degrees between 19Z to 05Z.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package... Isolated convection in
southern Nevada and western Arizona will wane between 06Z-09Z. Light
winds following typical overnight patterns are expected tonight into
Saturday morning. Winds Saturday will be similar to today,
increasing out of the south to southeast with gusts 15-20KT in the
afternoon. KDAG will be light through the afternoon before westerly
gusts develop around 00Z. Breezy southeast winds in the Owens Valley
may push smoke into KBIH, producing reduced visibilities and lower
CIGs at times. Convection on Saturday will be much more isolated and
less impactful compared to the past few days with the highest
chances for thunderstorms in central Arizona. Winds will follow
typical trends after sunset Saturday evening. VFR conditions will
prevail with CIGs at or above 12kft.
