Area Forecast Discussion
National Weather Service Las Vegas NV
1235 PM PDT Sat Aug 13 2022

.SYNOPSIS...A moist monsoonal flow will remain in place through
next week leading to a chance of heavy rain producing
thunderstorms across parts of the eastern Mojave Desert and
southern Great Basin. Generally dry weather is expected through
the weekend across the Sierra and Western Mojave Desert. These
western areas will see an increase again next week.
&&

.SHORT TERM...This Evening through Sunday.

For this evening, expecting any afternoon thunderstorm development
to end quickly after sunset as instability is already limited/capped
across the region due to clouds. The exception will be Lincoln
County where models show a consistent signal for an area of
precipitation to shift south after 00Z into northern and central
Lincoln County. HREF 3hr QPF for 1inch highlights this area from 00Z-
06Z as well. Ensured to linger precipitation chances through at
least 06Z for this area and increased precipitation amounts from
previous forecast per these model trends. Light showery activity may
continue at times after 06Z in Lincoln County through northern
Mohave, but impacts with these showers will be limited.

For Sunday- Very little change is expected in the overall airmass in
the next 24hrs, with high PWAT anomalies continuing to sit over
eastern San Bernardino, Clark, eastern Nye, Lincoln, and Mohave
counties. Model vorticity fields as well as simulated satellite
suggest continued influence from remnant MCVs in this area as well
on Sunday. But, compared to what we see today, expecting less cloud
cover Sunday morning which will lead to higher instability and a
potentially uncapped atmosphere. This should lead to more widespread
afternoon convection compared to today with potentially higher
impacts. Of note, HREF probabilities for over 1inch of 6hr QPF
suggests heavy rainfall and potential flash flooding in central
Mohave County through the higher terrain of Clark County. May also
see another complex of precipitation shift south through central and
southern Lincoln County into Mohave County tomorrow evening and
early overnight, which would be another focus for higher impacts.
Given the consistent signals from model reflectivities and
probabilities as well as continued high moisture available for storms
that develop- extended the Flash Flood Watch through Sunday evening.

.LONG TERM...Monday through Friday.

Ensembles show a weather pattern shift next week with high
pressure becoming repositioned further west over the central
Rockies. Ensemble mean forecasts have an inverted trough moving
westward across southern Texas and northern Mexico through the
week bringing additional moisture to the southwest by late next
week. This deeper pool of moisture is forecast to be south of our
area but a favorable southeast steering flow could send some of
this deeper moisture into our area resulting in an increasing
threat of widespread heavy rain and associated flash flooding.

&&

.AVIATION...For Harry Reid...Not expecting thunderstorm activity
directly over the terminal, but chances of storms in the vicinity
are likely, particularly over the higher terrain to the west and
south of the Las Vegas Valley. These storms have the potential to
kick off gusty winds from their direction. Storms aside, winds will
generally remain below 10 kts. Additionally, confidence is low, but
storms forming across Lincoln County tonight have the potential to
kick off a north-northeasterly outflow between 06 and 07Z tonight,
with gusts to 20 kts possible. SCT-BKN aoa 12 kft through the TAF
period.

For the rest of southern Nevada, northwestern Arizona, and
southeastern California...Best chances of vicinity thunderstorms for
both the Las Vegas Valley and the Colorado River Valley through 02Z
tonight, with gusty winds possible from their direction. Otherwise,
winds will favor diurnal speeds and directions. SCT-BKN aoa 12 kft
with lower ceilings expected with stronger nearby storm activity.
&&

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

LONG TERM...Salmen
