Area Forecast Discussion
National Weather Service Las Vegas NV
324 PM PDT WED JUN 29 2016

.SYNOPSIS...Monsoonal moisture will spread up from northern
Mexico Thursday and especially Friday leading to increasing coverage
of thunderstorms across the Mojave Desert region. Temperatures will
trend downward as the week rolls on but will warm once again as
drier conditions take hold early next week.
&&

.SHORT TERM...tonight through Friday night.

Thunderstorms have been active over Mohave county and south central
Nevada so far this afternoon as expected. Drier mid level air in the
southwest flow aloft over Clark County has largely ended the
thunderstorms that popped early over the mountains. The HRRR model
indicates storms will generally diminish around sunset, but we could
see convection over northern Mohave county in the late evening,
aided by the circulation moving over Lincoln county.

The main focus Thursday into Friday will be the deep moisture
pooling over northern Sonora Mexico and southwest Arizona that is
forecast to spread up into the region. We will see the leading edge
of this moisture make it up through southern and central Mohave
County by Thursday afternoon. The nose of this moisture may also
begin to work into Clark county. In addition, a 50-60 knot jet is
forecast to develop over northwest Arizona Thursday which should aid
convection. We should see the potential for some heavy rain
producing and possibly training storms over Mohave county Thursday
and there is some concern for significant flash flood potential with
some thunderstorms.

There is good agreement among the models that will see the first big
monsoonal moisture push of the season into eastern San
Bernardino...Clark and Mohave counties by Friday. CAPE values of
1000-1500 J/KG are forecast to be quite extensive with precipitable
water values of 1.25-1.50 inches. If cloud cover is
limited...surface heating will be the main driver of convection
Friday and we should see an active thunderstorm day with the
potential for heavy rain producing storms. Outflow from storms could
continue driving convection well into Friday evening given such as
moist and unstable environment.

.LONG TERM...Saturday through Wednesday.

Models showing mid/upper level drying from the southwest taking
place over the weekend. However, both the GFS/ECMWF indicate plenty
of low level moisture/instability in place to fuel convection. PW
values are forecast to be between 1.00 and 1.40 inches Saturday east
of a line from Twentynine Palms - Mt.
Charleston - Mesquite. Storm motion is forecast to be from the
southwest at 10-20 kts which should help mitigate flooding concerns
but locally heavy rainfall and gusty winds will accompany storms.

Can not rule a a few showers/thunderstorms in eastern Lincoln County
and northern Mohave County Sunday before this round of monsoon
moisture gets scoured out of the region in time for Fourth of July
revelers. In fact all of next week looks dry at this time with the
passage of a trough through the Pacific Northwest. The trough will
help enhance afternoon and evening southwest winds Monday-Wednesday.
Now that fuels are cured this will elevate fire weather concerns
early next week.

Influx of moisture/cloud cover should have some affect on
temperatures Saturday. Once drier air arrives temperatures will rise
back to some 3 to 5 degrees above normal Sunday-Wednesday.
&&

.AVIATION...For McCarran...Light to moderate southwest winds will
prevail through this evening and overnight though there is a slight
chance of erratic winds associated with thunderstorm outflow both
from storms to the north and east of Las Vegas. Thunderstorm
coverage will increase in the Peach Spring corridor Thursday and
there will be a slight chance for thunderstorms around the Las Vegas
Valley Thursday afternoon, but confidence is too low to mention in
the official forecast at this time.

For the rest of southern Nevada...northwest Arizona...and southeast
California...Scattered thunderstorms across the southern Sierra,
south central Nevada and northwest Arizona will largely dissipate
this evening. Thunderstorm coverage will increase over northwest
Arizona Thursday as increasing monsoonal moisture spreads up from
northern Mexico.
&&

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

Short Term/Aviation...Adair
Long Term...Pierce
