.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 12Z Forecast Package...South
winds will remain under 8KT overnight with light and variable winds
developing after sunrise. Much like the past few days, south to
southwest winds will increase after 18Z with gusts up to 20KT
expected through the afternoon. VFR skies with CIGs at or above
15kft. Temperatures will exceed 100 degrees between 19Z to 06Z with
a high around 114F.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package...Winds generally less
than 10 knots this morning, increasing out of the south to southwest
with gusts 15-20 knots this 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
today will mainly be focused over northwest Arizona and little to no
impacts on TAF sites. VFR conditions will prevail with CIGs at or
above 15kft.
