.SYNOPSIS...Temperatures continue to climb through midweek under a
ridge of high pressure. Extreme Heat Warning in effect for the lower
elevations of the Mojave Desert Monday and Tuesday before
temperatures gradually decline through the remainder of the week.
Isolated thunderstorm activity will continue each afternoon across
the southern Great Basin, with primary impacts being frequent
lightning and gusty winds. Otherwise, expect breezy southwest winds
each afternoon this week.

&&

.UPDATE...
Convection across the Southern Great Basin, Arizona Strip, and
northern Inyo County is on a downward trend early this evening,
with continued weakening expected over the next few hours.
Lightning strikes and gusty outflow winds remain possible,
especially across northern Inyo and Esmeralda Counties, with
little in the way of appreciable rainfall expected. Otherwise,
temperatures have begun their slow downward trend this evening,
though lows tonight are expected to only reach the 70s and lower
80s for most, with 60s in the mountains. Thus, overnight lows will
provide little relief ahead of an even hotter day tomorrow, with
an Excessive Heat Warning in effect beginning tomorrow morning
across portions of the Mojave Desert. The forecast remains on
track this evening, with no updates warranted at this time.

.SHORT TERM...Today through Tuesday.

A closed area of low pressure off the southern California coast will
weaken into an open wave as it moves inland across the Mojave Desert
today and Monday. This low will tap into remnant moisture across the
region and will use diurnal heating to its advantage... resulting in
afternoon isolated showers and thunderstorms through Tuesday. Best
moisture exists across the southern Great Basin, where isolated
thunderstorm chances are greatest. That said, "best moisture" means
about 0.40 to 0.70 inches of PWAT (which is 100-150% of normal for
this time of year). So, while the moisture is anomalous, there`s not
much of it to result in flash flooding impacts or heavy rainfall.
Expect frequent lightning and erratic, gusty winds, with brief
moderate rainfall possible. In general, most storms will simply
produce virga (rain that evaporates before reaching the surface).
With DCAPE values between 1200 and 1600 J/kg, gusty winds between 30
and 40 mph are expected with stronger storms. Expect similar
conditions Monday and Tuesday.

Meanwhile, a growing area of high pressure centered over northern
Mexico will allow temperatures to rise to 8 to 12 degrees above
seasonal normals. Temperatures will peak Monday night (warm
overnight lows) and Tuesday (hot afternoon highs). As such, the
Extreme Heat Watch was upgraded to an Extreme Heat Warning on the
previous shift. This warning goes into effect Monday and Tuesday for
northwestern San Bernardino, far southern Nye, Death Valley National
Park, lower elevations of Clark County (including Las Vegas), and
the Colorado River Valley (including the Lake Mead National
Recreation Area). In these areas, HeatRisk will be "Major" (level 3
on a scale of 0 to 4). Major HeatRisk means that the heat affects
everyone who does not have access to adequate cooling or hydration.
If you have plans recreating outside on Monday or Tuesday in these
areas, it is recommended that you schedule your activities during
the cooler parts of the day and bring more water than you think
is necessary.

.LONG TERM...Wednesday through Sunday.

A strong area of low pressure will drop out of the Gulf of Alaska
into the Pacific Northwest mid-to-late week. As this occurs, a
trough will extend along the California coast, placing our forecast
area between the aforementioned trough and a strong area of high
pressure over northern Mexico. The resultant tightened pressure
gradients will return breezy southwesterly winds to the region each
afternoon Wednesday onward.

This trough has trended slower with each model run. Originally, it
was going to drop temperatures closer to seasonal normals heading
into this weekend. Now, though temperatures do gradually decrease,
they remain 5-8 degrees above normal, with desert valleys staying in
the triple-digits. This trough will retrograde into the Pacific
Ocean and loiter off of the California coast into next week.

.AVIATION...For Harry Reid...For the 06Z Forecast Package...Winds
are expected to remain under 10KT through the forecast period,
and generally follow diurnal patterns until just after 10/00Z.
There is a low chance (20%) for thunderstorms to develop across
the Spring Mountains and northern Clark County during the
afternoon, and these storms could send gusty outflow winds south
across the Valley, impacting the terminal. Uncertainty in timing
and magnitude of winds exists, though have included a brief
northerly shift during the late afternoon and evening to account
for this outflow. Otherwise, VFR conditions prevail the next 24
hours, with temperatures expected to exceed 100F between 20Z-04Z,
peaking at 105 around 00Z.


For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...Winds across the
region will generally follow typical diurnal patterns, with the
exception of Las Vegas Valley terminals as well as northern Inyo
County and the Southern Great Basin where outflow winds from
thunderstorms in the afternoon could result in variable and
briefly elevated/gusty winds. Also, across the Western Mojave,
expect intermittently gusty westerly winds overnight as well as
during Monday evening. Otherwise, VFR conditions prevail with mid
and high clouds affecting terminals north of I-15 during the
afternoon and evening.
