.KEY MESSAGES...

* Isolated convection capable of producing sudden gusty winds
  will be possible across northwestern Arizona this afternoon.

* Hotter than normal temperatures will continue into the week,
  with temperatures peaking on Monday when multiple heat headlines
  are in effect.

* Monsoonal moisture will return to the region late this week,
  bringing increased chances for afternoon showers and
  thunderstorms.

.DISCUSSION...through next weekend.

Precipitable water values have increased into the 0.50 to 0.90 inch
range across Mohave County and portions of Clark and San Bernardino
counties. While modest, this moisture combined with 100 to 200 J/kg
of CAPE from surface heating in northwestern Arizona will be enough
to help fuel weak isolated convection in Mohave County this
afternoon. Given the dry low-levels of the atmosphere, most, if not
all, of the precipitation is expected to evaporate before making it
to the surface. These dry low-levels combined with evaporative
cooling mean that sudden gusty winds will be possible with any virga
showers that develop. Any convection that does develop will diminish
after sunset.

Temperatures today will be a degree or two hotter than yesterday,
with the warming trend continuing through tomorrow as the ridge of
high pressure continues to build over the Southwestern US. As
temperatures peak tomorrow, we will see widespread Moderate (Level 2
of 4) to Major (Level 3 of 4) HeatRisk across the southern Great
Basin and Major HeatRisk across portions of the Mojave Desert. As
such, an Extreme Heat Warning has been issued for Death Valley
National Park, Clark County, and the Lake Mead National Recreation
Area; and a Heat Advisory has been issued for the southern Great
Basin for tomorrow. In addition to hotter than normal
temperatures, much of our forecast area will continue to
experience hazy skies as smoke from area wildfires circulates
under the bubble of high pressure.

Our ridge of high pressure will weaken and retreat in response to a
shortwave moving through the northwestern US. These falling 500 mb
heights will allow for temperatures to "cool" back down to near
normal during the middle of the week. Meanwhile, a cut-off low will
develop off the coast of the Baja Peninsula during the middle of
the week, which will help to transport moisture back into the area
towards the end of the week. There still remains uncertainty
regarding the magnitude of this moisture increase and how far into
our forecast area the moisture will penetrate, both of which will
play a role in precipitation chances, amounts, and impacts.

.AVIATION...For Harry Reid...For the 00Z Forecast Package...Light
winds should tend to favor a southeasterly direction into the
evening, eventually switching to the southwest. The diurnal trend
continues through tomorrow, including breezy southwesterly winds
tomorrow evening with moderate gusts to around 15 knots. Isolated
virga showers cannot be ruled out in the Peach Springs corridor this
evening. Smoke from area wildfires will remain aloft through the TAF
period. Temperatures will exceed 100 degrees between 18Z and 06Z,
peaking around 112 degrees.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 00Z Forecast Package...Winds continue to follow
diurnal directional trends with sustained speeds of 12 knots or
less. Breezy westerly winds will pick up across the western Mojave
Desert this evening, continuing into the overnight hours. Virga
showers will be possible this evening across northwestern Arizona
and far southern Nevada and may be capable of producing gusty and
erratic outflow winds. Slantwise visibility will continue to be
impacted by wildfire smoke aloft, but visibility restrictions at the
surface are not expected.

&&

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report
any significant weather or impacts according to standard operating
procedures.
