.KEY MESSAGES...

* Other than a low chance for showers on the Sierra crest this
  afternoon, dry conditions are likely through the week.

* Haze is possible today and Tuesday as south winds push elevated
  smoke in from fires in Baja California.

* Below-normal temperatures are expected through Wednesday before
  rising to near normal and then above normal later in the week.

.DISCUSSION...through Monday. Midnight satellite loop showed low
pressure centered over south central California moving slowly east.
On the front side of this low, a jet streak was pushing northward
from southern California into east central Nevada. This was helping
to drive elevated convection over Nye and Lincoln counties. No
lightning had been detected, but two wind gusts of 60 and 77 mph had
been recorded on the NNSS, presumably from "virga bombs" evaporating
in the dry subcloud air. By sunrise, the jet streak should no longer
be in a favorable position to generate lift over our CWA, and the
low will slowly fill and drift east through the day. Afternoon
convection, if any, should be limited to the Sierra Nevada where
orographic lift will be maximized. The other feature of interest
will be smoke and haze from distant wildfires. Wednesday through
Sunday should be relatively quiet over our area, with breezy
afternoons and a warming trend pushing temperatures above normal as
heights rise overhead. At this time, there are only tiny splotches
of Major HeatRisk expected on Sunday. This very low coverage is
probably more due to the time of year, as we are getting within a
few degrees of the climatologically hottest time of the year, so it
is more difficult to have unseasonably hot conditions. That said,
even temperatures a few degrees above average can be dangerous for
those with poor heat tolerance or without access to air
conditioning. Monday is more uncertain, as there is good model
agreement on the existence of low pressure nearing the California
coast, but not such good agreement on whether this low will be able
to tap into moist monsoon flow which should be established over New
Mexico and perhaps Arizona.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...South-
southeast winds expected this afternoon at all the valley TAF sites
by 19Z or 20Z, with gusts to around 15KT likely. After sunset,
expect winds to diminish then follow typical wind patterns
overnight. LAS will see their usually south-southwest wind at 8KT or
less, becoming variable by Wednesday morning. Light winds will
continue through Wednesday afternoon following normal daytime
directional patterns. FEW-SCT clouds around 15kft are expected this
afternoon which will clear tonight. Haze is possible at times
through Wednesday due to smoke, however surface smoke and visibility
reductions are not expected.

For the rest of southern Nevada, northwestern Arizona and
southeastern California...For the 18Z Forecast Package...Breezy
south to southeast winds will set up again this afternoon across the
region, with gusts up to 20KT possible at times, especially in the
Colorado River Valley. The exception will be KDAG, where directions
will remain mainly westerly through the TAF period, with gusts to
over 20KT expected through the first part of the night. Showers and
thunderstorms may develop on the Sierra crest this afternoon but
will not impact nearby valleys other than some SCT-BKN CIGs around
12kft at KBIH, which should diminish after sunset. Light winds are
expected tonight through early Wednesday morning. VFR conditions
should prevail across the region through the TAF period. Haze from
regional wildfires may result in reduced slantwise visibilities
today and Wednesday across the Mojave Desert. &&

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