Area Forecast Discussion
National Weather Service Las Vegas NV
235 PM PDT Fri Aug 12 2022

.SYNOPSIS...Moist monsoonal flow will remain in place through
next week leading to the potential for thunderstorms with heavy rain
over the eastern Mojave Desert and southern Great Basin. Further
west across the Sierra and Western Mojave Desert, generally dry
weather expected over the weekend with increasing storm chances next
week.
&&

.SHORT TERM...through Sunday.

Thunderstorms got going a little early today. There was a
circulation over Lincoln and northern Clark Counties and a also one
lifting up from southwest Arizona in addition to the surface heating
and the moist and unstable air mass that remains in place over
southern Nevada, northwest Arizona and far southeast California.
Boundary interaction will come into play with additional storm
development through the late afternoon and early evening. The latest
HRRR indicates the potential for thunderstorms converging over the
Las Vegas area this afternoon then propagating southward this
evening. Storms should dissipate late this evening and overnight
then conditions Saturday look quite similar to today, though any
storm induced circulations are a wildcard. The Flash Flood Watch was
extended through Saturday evening for zones where it is currently in
effect. We should see similar thunderstorm development with
scattered to numerous slow-moving storms with the potential heavy
rain. There is not much change in expectation with storm development
through Sunday, so plan on more of the through the weekend.

.LONG TERM...Monday through Friday.

As we head into next week, the monsoon shows little sign of slowing
down with rich moisture locked in place across the Mojave Desert and
southern Great Basin. Meanwhile, high pressure builds into the
northern Great Basin which could shift the steering flow to a more
north or northeasterly direction for a few days, a favorable pattern
for thunderstorm complexes moving into the lower deserts. Aside from
the daily storm chances, temperatures will remain at or below normal
through the period, with the greatest departures from normal across
the eastern Mojave Desert where deeper monsoonal moisture will be
hanging around.
&&

.AVIATION...For Harry Reid...Scattered thunderstorms are forecast
for the area once again this afternoon.  The best chances of seeing
direct impacts on the field are between 22Z and 02Z, with primary
impacts being gusty outflow winds, brief heavy rainfall, and
lightning.  Outside of thunderstorm activity, light southerly winds
and skies FEW-SCT AOA 10kft are expected.  Little change in the
overall pattern is expected over the weekend keeping the chance of
afternoon and evening storms in place through at least Sunday.

For the rest of southern Nevada, northwest Arizona and southeast
California...Scattered thunderstorms are expected at all TAF sites
today with the exception of KBIH. The best chance of seeing storms
will be mainly after 22Z and any storms will be capable of producing
gusty winds, brief heavy rain and lightning.  Outside of
thunderstorm activity expect light winds favoring typical diurnal
variations and FEW-SCT skies AOA 10kft. Little change in the overall
pattern is expected over the weekend maintaining the threat of
afternoon and evening storms through at least Sunday.
&&

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