.DISCUSSION...Today through Monday.

The Desert Southwest remains sandwiched between two ridges - one
over the northeastern Pacific Ocean and one over New Mexico. Over
the next few days, the Pacific Northwest high will meander southeastward,
centering itself over our forecast area by Tuesday. As a result, expect
persistent above-normal temperatures, with afternoon readings ranging
4 to 8 degrees above seasonal normals. Extreme Heat Warnings are in
effect for Death Valley National Park, western and southern San Bernardino
County, far southern Nye County, northwestern Clark County, and southern
Mohave County at 10 AM this morning, with areas expanding to include
the Las Vegas Valley, eastern and southern Clark County, and eastern
San Bernardino County on Tuesday. Heat Advisories are in effect on
Tuesday for the Owens Valley, Esmeralda County, central Nye County,
Lincoln County, northern Mohave County, and the Clark County Mountains,
as higher elevations will provide minimal respite from valley heat.
Today and Tuesday, expect widespread Moderate Heat Risk, with increasing
coverage of Major Heat Risk (with isolated instances of Extreme) across
lower elevations. With the center of the high overhead, temperatures
are slower to cool off Wednesday onward. Will continue to assess over
the next couple of shifts, but temperatures in lower elevations may
warrant an extension of Extreme Heat Warnings into Wednesday. Troughing
approaches the Pacific Northwest late-week, which will deamplify the
aforementioned ridges and bring cooler temperatures to the region heading
into next weekend.

Another cell formed over the San Bernardino Mountains south of State
Route 62 yesterday afternoon. PWATs will retreat from southern San
Bernardino County today as the PacNW high noses into the region, so
we are not expecting anymore shower or thunderstorm activity this
afternoon. As mentioned in previous forecast discussions, modest
moisture increases across the southern Great Basin on Wednesday,
which has increased PoPs on Wednesday across our northern zones to
10 to 20%. Meanwhile, both the ECMWF and GFS ensemble means indicate
that a southerly flow mid-to-late week will bring 0.75 to 1.25 inches
of monsoonal PWAT to far southern Nevada, far southeastern California,
and northwestern Arizona. PoPs will range 30 to 50% across eastern
Mohave County Wednesday through Saturday, with between 10 and 30%
PoPs across Lincoln, Clark, and eastern San Bernardino counties. Most
likely impacts include gusty winds, frequent lightning, and isolated
instances of heavy rainfall, particularly with storms that form over
the higher terrain.

.AVIATION...For Harry Reid...For the 06Z Forecast Package...Southwest
to occasional west winds are expected through much of the overnight
period with speeds generally around 8-10 knots. We should also see
a period of light and variable winds early this morning. Light
northeasterly winds should return late this morning, and could
persist all day until shifting back to southwest around sunset. No
operationally significant clouds or weather expected at the
terminal, although wildfire smoke could reduce slantwise
visibility aloft. Temperature falling below 100F around 04Z this
evening and back above 100F from roughly 18Z to 04Z tomorrow,
peaking around 108F.

For the rest of southern Nevada, northwestern Arizona and
southeastern California...For the 06Z Forecast Package...Wind
gusts generally 15 knots or less areawide today, although some
gusts to around 20 knots are possible near KDAG. Lofted smoke
across San Bernardino County and far southern Nevada may reduce
slantwise visibility at times.

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