.DISCUSSION...Today through Sunday.

Through the start of the work week, the Desert Southwest will be
sandwiched between two ridges - one over the northeastern Pacific
Ocean and one over New Mexico. This will allow temperatures to
remain fairly stable for the next few days, with afternoon readings
ranging 4 to 6 degrees above seasonal normals. Temperatures peak on
Monday and Tuesday. 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 on Monday, 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. Monday and Tuesday, expect widespread Moderate Heat
Risk, with increasing coverage of Major Heat Risk across lower
elevations. Troughing approaches the Pacific Northwest late-week,
which will deamplify the aforementioned ridges and bring cooler
temperatures to the region heading into next weekend.

Yesterday, an isolated cell formed over the higher terrain south of
Twentynine Palms, producing heavy rainfall. With persistent 0.75 -
1.00 inches of PWAT across far southern San Bernardino County,
coupled with daytime heating and higher terrain, cannot discount a
similar situation this afternoon along the State Route 62 corridor.
Modest moisture increases across the southern Great Basin on
Wednesday, which has increased PoPs on Wednesday across our northern
zones to 5 to 15%. 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...Winds
will continue to maintain a southwesterly direction through early
Sunday morning when they will become light and variable. Winds
will remain light, swinging around to the east-northeast tomorrow
morning. These ENE winds will continue through the afternoon and
into the evening when winds will pick up slightly and swing around
to the southwest. FEW to SCT high clouds will filter through the
area tonight and tomorrow. Temperatures will exceed 100F between
19 and 04Z, peaking around 108F.

For the rest of southern Nevada, northwestern Arizona and
southeastern California...For the 06Z Forecast Package...With the
exception of the western Mojave Desert and Colorado River Valley,
winds across the rest of the area will tend to follow typical
diurnal directional trends. Winds across the western Mojave Desert
will favor a westerly direction through the TAF period while
winds in the Colorado River Valley favor a more southerly
component. Breezy southerly winds will pick up in the Colorado
River Valley tomorrow afternoon with gusty westerly winds picking
up across the western Mojave Desert tomorrow evening. Otherwise,
winds will remain relatively light, 12 knots or less. Lofted
smoke/haze will be possible across San Bernardino County and may
impact slantwise visibility at times. Otherwise, FEW to SCT high
clouds will filter through the area tonight and tomorrow.
