Area Forecast Discussion
National Weather Service Las Vegas NV
115 PM PDT Wed Jul 26 2017

.SYNOPSIS...With a moist airmass still in place, at least a slight
chance of showers or storms will exist through this evening in most
areas. Gradual drying and warming is expected through the rest of
the work week. Another uptick in moisture and thunderstorm chances
is expected this weekend into early next week.
&&

.SHORT TERM...Today through Friday.

Storms are developing once again this afternoon mainly across
eastern Inyo...central Nye and Lincoln counties. Additional
thunderstorms may still develop across the mountains of Clark
county. Environment especially north of I-15 is characterized by
moderate instability and relatively strong wind shear for our region
this time of year (20-30 knots of effective shear). This means
storms which develop will tend to move northward fairly swiftly,
minimizing the flooding risk. But stronger shear interacting with
moderate instability will also result in an elevated threat of hail
and damaging wind gusts for the stronger storms that form.  Activity
will tend to lift northward through the evening, with best chances
for precipitation becoming limited to Lincoln and central Nye
counties by later this evening.

Drier conditions are in store tomorrow and Friday with only minimal
terrain driven convection anticipated across northern Lincoln and
Mohave counties. Low level moisture never really gets scoured out,
so it will remain a bit more humid than normal, but warming aloft
will limit thunderstorm chances for most of the area, with just fair
weather cumulus expected outside of the highest terrain.
Temperatures will return to near normal Thursday and Friday.

.LONG TERM...Saturday through Wednesday.

Still anticipating another ramp up of convection and rain chances
over the weekend as an inverted trough pushes westward across
Arizona and into the Mojave Desert. There remains some timing
differences on when the inverted trough will arrive and how much
moisture it will bring with it, but widespread thunderstorm activity
can again be expected through early next week as it moves through.
Chances will begin to rise by Saturday afternoon as deeper moisture
and Precipitable water values of 1-1.5" inches push into areas
south of I-15. By Sunday and Monday, those values will rise to
between 1.25-1.75" for the same areas, so flash flooding potential
will be an increasing concern.   Along with the incoming moisture,
temperatures will begin trending downward Saturday onward, and
stay below normal for most of the first half of next week.

&&

.FIRE WEATHER...Conditions will be trending drier Thursday and
Friday as slightly drier and more stable air moves into the region.
Thunderstorm chances will be limited to mainly the higher terrain of
Lincoln and Mohave counties. Temperatures will rise near to slightly
above normal through Saturday before trending cooler as another
surge of monsoonal moisture pushes in. Scattered to numerous
thunderstorms return to the forecast Saturday evening onward, mainly
east and south of Inyo County.

&&

.HYDROLOGY...Creeks, streams and rivers in northern Inyo County
have shown decreasing flows over the last couple of days.
However, some road closures continue in the area. Bishop Creek
Bypass and Big Pine Creek Bypass continue to be utilized to
minimize flows through Bishop and Big Pine. Remember, never drive
through flooded roadways or around barricades. Also, pastureland
or farmland adjacent to creeks, streams or rivers could experience
areas of standing water.
&&

.AVIATION...For McCarran...Mainly southeast winds expected today,
staying below 8kts for the most part...with the 00z-03Z timeframe
having some possibility of winds up to 10kts. Will need to watch for
the possibility of outflow winds though as thunderstorms develop
mainly north and west of the airspace. Storms should stay away from
the airport, with a small chance of a stray storm between 20z- 00z
this afternoon. Similar conditions are expected Thursday, with
considerably lower chances for storm activity.

For the rest of southern Nevada, northwest Arizona and southeast
California...Light, diurnal winds are expected to give way to
enhanced south to southeast winds in most areas today.
Shower/thunderstorm activity is expected again today, with the best
chances over north and west of Las Vegas in Nye and Lincoln
Counties, with just isolated storms elsewhere. Mainly light south to
southwest winds are expected Thursday, with considerably lower
chances for storm activity.

&&

.SPOTTER INFORMATION STATEMENT...While storms may not be as
widespread today, storms will still be possible over much of the
region. Spotters are encouraged to report any significant weather
or impacts according to standard operating procedures.
&&

SHORT TERM/FIRE WEATHER/LONG TERM...Outler
