.DISCUSSION...through the weekend.

Troughing across the Southwestern US will result in dry
southwesterly flow across southern Nevada, northwestern Arizona,
and southeastern California, which will help dry conditions
persist for through the week for most of the region. The one
exception to this will be the Sierra Crest, where there is around
a 15 to 20% chance for isolated showers and thunderstorms this
afternoon. These low precipitation chances are a result of a a
shortwave off the coast of California shifting inland and
resulting in upslope flow on the windward side of the Sierra. This
upslope flow will provide enough lift for weak showers and
thunderstorms to develop across the crest of the Sierra. Outside
of the Sierra crest the only evidence of this shortwave will be
breezy southerly winds this afternoon.

Increasing 500 mb heights will allow for temperatures to gradually
warm up throughout the week with warmer than normal temperatures
returning during the second half of the week. Temperatures a few
degrees above normal will result in Moderate (Level 2 of 4) HeatRisk
spreading across much of the region over the weekend. This level of
heat will impact anyone without access to proper cooling and/or
adequate hydration as well as heat sensitive individuals. Those
planning on recreating outdoors this weekend should keep an eye on
forecast temperatures and take steps to mitigate adverse heat
impacts (e.g., taking extra water and sports drinks with you,
putting on sunscreen, and wearing light colored and lightweight
clothes).

.AVIATION...For Harry Reid...For the 12Z Forecast Package...Light,
variable winds will continue through mid-morning before turning
mainly easterly by 17Z.  A period of southeast winds with gusts to
20 knots is then expected after 19Z.  There are some uncertainties
about when winds will turn to the southwest.  The current forecast
indicates the turn will occur by 03Z, but some guidance suggests it
could happen as early as 23Z.  Once the turn does occur, expect the
southwest winds to continue into Tuesday morning, possibly becoming
variable after 09Z.  Haze from regional wildfires may result in
reduced slantwise visibilities throughout the day, with a slight
reduction of surface visibilities possible in the late afternoon.

For the rest of southern Nevada, northwestern Arizona and
southeastern California...For the 12Z Forecast Package... Light and
diurnal winds will continue through this morning before breezy south
to southeast winds with gusts to around 20 knots set up across the
region this afternoon. The exception will be KDAG, where directions
will remain mainly westerly through the TAF period. Haze from
regional wildfires may result in reduced slantwise visibilities
throughout the day across the Mojave Desert, with a potential
reduction in surface visibilities for Las Vegas Valley TAF sites in
the late afternoon.

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report
