.SYNOPSIS...Isolated-to-scattered showers and thunderstorms are
expected across southern Nevada and northwest Arizona this afternoon
with lesser chances in southeastern California. Gusty outflow winds,
frequent lightning, small hail, and moderate-to-heavy rain will be
threats with any storms that develop. Additional weaker storms are
possible tomorrow. Things will begin to dry out and heat up as we
head into the weekend.

&&

.UPDATE...

Showers and thunderstorms continue percolating across the area
early this evening, though coverage has decreased fairly
significantly over the past few hours. Per the 00Z KVEF sounding,
PWATs have already started to drop, and while localized moderate
to heavy rain remains possible, the flash flooding threat is also
decreasing. The strongest storms are currently located near Baker,
CA on I-15, though latest high-resolution guidance indicates this
activity will diminish after sunset, becoming weaker as it drifts
northeastward. Elsewhere, lightning strikes, downpours, and gusty
winds remain possible for the next few hours, so those outdoors
this evening will need to stay aware and seek shelter if thunder
or lightning are observed. Overall, the forecast this evening
remains on track, thus, no updates are warranted at this time.

.SHORT TERM...Today through Friday.

An elongated positively tilted 500 mb trough will move east through
the forecast area today. Increased vorticity advection combined with
plentiful moisture (PWATs 100 to 200 percent of average) and daytime
surface heating has already led to thunderstorm development over
Mohave County and parts of southern Nevada as of 12 PM PDT. The
strongest storms over far southern Clark County feature cloud tops
above 30,000 feet and are producing heavy rainfall and frequent
lightning. Hail and strong outflow winds are possible with any
storms today, but weaker shear should result in smaller hail
compared to earlier this week. Guidance shows storms becoming more
numerous through the day as instability increases with surface
heating. Convection should taper off tonight as surface heating ends
and atmospheric instability is exhausted by storm activity.

Although moisture and instability decrease tomorrow, there should be
enough left for some isolated storm development in the afternoon.
SBCAPE values fall to 500 J/kg or less with PWATs still around 200
percent in some areas. Storm activity will primarily be over high
terrain where lift is the greatest. Outside of storms, temperatures
return to near average temperatures for early June, which for Las
Vegas means highs in the mid 90s.

.LONG TERM...Saturday through Wednesday.

A return to more typical early June hot and dry conditions is on
tap for southern Nevada, southeastern California and northwestern
Arizona starting this weekend. Ensemble guidance and cluster
analyses remain in good agreement regarding a strengthening ridge
over the region, which will facilitate a decrease in moisture and
gradually warming temperatures, warming to well above normal
Sunday through at least Tuesday. Fairly widespread highs in the
90s and lower 100s are expected Sunday through Tuesday, with
Monday and Tuesday looking to be the hottest days of the forecast.
Along with the warming temperatures will be increasing HeatRisk,
with "Major" HeatRisk returning to Death Valley and the Lower
Colorado River Valley on Saturday, gradually expanding across
other lower elevations through early next week, with "Extreme"
HeatRisk possible for the lowest Valleys Monday and Tuesday.
Thereafter, ensemble members begin to diverge, with some
indications that a weak trough may try to undercut the ridge
heading into midweek, but with little in the way of moisture, this
trough would have little impact other than tempering the hot
temperatures by a couple of degrees, and producing some breezy
conditions. Stay tuned.

.AVIATION...For Harry Reid...For the 06Z Forecast
Package...Low confidence through 8z with showers and thunderstorms
moing through areas mainly south of Las Vegas. These storms may clip
the southwest valley with brief heavy rain and gusty winds. A push
of southerly outflow winds is also anticipated. By late tonight
improving conditions are expected with winds decreasing.  A few weak
showers and thunderstorms will again be possible tomorrow after 18z,
with brief light rain and locally gusty winds the main impacts.
Coverage and intensity expected to be much less than previous days.
Outside of convective influences, winds should be relatively light.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...Lingering showers and
storms persist through the Daggett corridor but will die off by
midnight. Tomorrow, additional showers and thunderstorms should
develop after 18Z on Friday in southern Nevada and western Arizona,
however convection on Friday will be less widespread and less likely
to produce impacts compared to today. Otherwise, generally light
winds expected outside of thudnerstorm influences.

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