Area Forecast Discussion
National Weather Service Las Vegas NV
1137 AM PDT Mon Aug 15 2022

.SYNOPSIS...Afternoon thunderstorm chances to persist through the
week, bringing the potential for heavy rain and flash flooding.
Temperatures remain below-normal due to monsoon moisture and rain
chances.
&&

.SHORT TERM...Today and Tuesday.

Morning satellite imagery depicts an MCV positioned over central
Mohave County, collocated with abundant cloud cover that
stretches up into northeastern Utah. These clouds are expected to
erode this afternoon, allowing Mohave and eastern Clark Counties
to destabilized, albeit a bit delayed and less than typical. This
may temper afternoon storm activity across the county, but with
deep moisture and the MCV present, heavy rain and flash flooding
remain likely with any storms. As such, a flash flood watch
remains in effect for Mohave County through tonight. Elsewhere,
where skies are clearer, scattered storms are expected to develop
along the higher terrain. Morning CAMs show activity spreading
farther west than yesterday, possibly into Death Valley and the
Sierra. Given the more isolated coverage outside of Mohave County,
the flash flood watches for these areas were allowed to expire,
though flash flooding will remain possible with any storm. Think
we'll have keep an eye out for a potential northeast event this
evening, as the MCV over Mohave County places the I-15 corridor
between Vegas and St. George under northeasterly flow. We almost
got one last night, and the setup looks more favorable today. Hi-
res guidance doesn't seem too keen on this idea, perhaps due to
the cloud cover currently in the area. However, these clouds
should erode this afternoon and Lincoln County is already clear,
so storms should develop and propagate south-southwest. Whether
they make it into the Las Vegas Valley remains uncertain, but the
potential is there. Heavy rain, flash flooding, and strong winds
would be possible should this scenario occur.

Tomorrow, activity continues to spread west, with scattered
thunderstorms possible across the entire CWA. Latest HREF suggests
the greatest coverage will be southeast of I-15, but shows scattered
development out into Inyo and Esmeralda Counties. While these areas
have gotten a much needed break, they remain very vulnerable to
flash flooding and their thunderstorm potential will need to be
monitored closely. Otherwise, tomorrow looks to be more of the
same, with afternoon thunderstorms and below-normal temperatures.

.LONG TERM...Wednesday through the weekend.

Synoptic-scale south-southeast flow is expected to persist through
the week, keeping moisture and storm chances around. Not seeing much
in the way of larger-scale forcing mechanisms in ensemble guidance,
so mesoscale features will be key. This means that pinpointing areas
of greatest activity is likely going to be a day-by-day process.
Nonetheless, heavy rain and flash flooding will continue to be the
main hazards. As we head into the weekend, things become a little
more interesting as the remnants of a Gulf of Mexico tropical system
slide under the ridge and into southern Arizona. Guidance generally
keeps this system south and east of our area, but this hinges on the
timing of a westerly shortwave and the strength of the ridge.
Changes in these details will likely alter the trajectory of
tropical remnants/inverted trough. Should the system impact our
area, it will bring the potential for widespread heavy rainfall;
however, uncertainty remains high at this moment. What is more
certain is the continuation of below-normal temperatures with the
persistent moisture and rain chances.
&&

.AVIATION...For Harry Reid...Generally minor impacts expected today
with light winds through the majority of the TAF period. Another
opportunity for gusty outflow winds this afternoon due to monsoonal
thunderstorms in the vicinity of the LV valley but confidence is
quite low. However, maintained TEMPO group for this potential this
afternoon and evening. Quieter conditions overnight with FEW-SCT
clouds around 12-15k feet along with light winds. Similar conditions
expected Tuesday with Isolated afternoon thunderstorms and generally
easterly winds outside of any thunderstorm influences.

For the rest of southern Nevada, northwest Arizona and southeast
California...Lesser overall coverage of monsoonal thunderstorms
expected across the region today, with the exception of Mohave
County where thunderstorm coverage is expected to be more scattered.
However, any storms that develop will likely produce outflows and if
so, the terminals with the best potential for impacts would be
KIFP/KEED as well as KVGT/KHND. Otherwise, generally light winds
expected across the region today. Similar conditions are expected
Tuesday with scattered afternoon thunderstorms, mainly over the
eastern half of the area.

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