Area Forecast Discussion
National Weather Service Las Vegas NV
203 AM PDT Sat Sep 14 2019

.SYNOPSIS...Temperatures will remain above average through the
weekend. Late this weekend into early next week, another weather
system will impact our area, resulting in the return of strong
winds, cloudy skies and significantly cooler temperatures. Late next
week, breezy conditions are expected to return as another weather
system impacts our area.
&&

.DISCUSSION...Today through next Saturday.

Dry and sunny conditions persist today with above-average
temperatures due to a zonal flow that has set up across our area.
Afternoon highs are expected to reach 5-8 degrees above seasonal
averages with the Las Vegas Valley, Colorado River Valley and Death
Valley expected to surpass the century mark through the weekend.

However, a digging trough approaching the western United States
coast and begin bringing impacts to our region late this weekend
into early next week. These impacts include isolated shower and
thunderstorm activity for northwestern Arizona, a widespread drop in
temperatures and very windy conditions for much of the southern
Great Basin.

Due to this pattern shift, a brief southerly flow will bring a mild
moisture flux to northwestern Arizona. This afternoon, highest
chances for showers and thunderstorms look to remain south and east
of our area, though isolated storm activity on our southern border
is not out of the question. As a result, slight chance of isolated
showers and thunderstorms are possible for southern Mohave County
this afternoon. Due to the moisture flux in place, chances of
isolated convection return each afternoon through Tuesday for Mohave
County. As a result of any storm activity, the chances for strong,
gusty outflow winds into southern Nevada and southeastern California
are possible.

Through the overnight hours of Sunday going into early Monday
morning, winds start to pick up down the eastern Sierra slopes. This
downslope wind event will carry through Monday with speeds
potentially over 60 mph impacting the eastern slopes and the Owens
Valley. Through the day on Monday, increased wind speeds spread
across Inyo County and into southern Nevada. Widespread gusts 40-45
mph expected with stronger speeds in the higher terrain. Wind speeds
will likely reach wind headline thresholds. Will continue to monitor
how the forecast progresses and issue products accordingly.

As this digging trough exits our area through Tuesday, an associated
cold front will plummet temperatures across the region. Forecast
highs will have an 8-12 degree drop between Sunday and Tuesday with
many areas seeing below-90 degree afternoon temperatures.

Ensemble and deterministic models have begun to resolve the next
weather system forecast to impact our region for the end of the work
week. Another trough is expected to dig from the Pacific NW into our
area Thursday. Impacts associated with this include persistent high
temperatures in the upper-80s to lower-90s and a return of breezy
conditions.
&&

.FIRE WEATHER...Dry conditions continue today with high
temperatures 5-8 degrees above seasonal averages. Fire Weather
Watches remain in effect for Inyo County fire zones Sunday afternoon
through Monday night and for southern Nevada fire zones Monday
afternoon through Monday night. However, it appears conditions for
strong downslope winds will start to develop late Sunday evening
followed by periods of potentially high winds with gusts over 60 mph
on Monday. Widespread gusts over 40 mph appear likely over the
southern Great Basin Monday afternoon and evening. These wind speeds
will be accompanied by minimum RH values in the single-digits to low-
teens.
&&

.AVIATION...For McCarran...Expect light winds this morning, becoming
easterly this afternoon and southwesterly in the evening, with
speeds under 10 knots 90 percent or more of the time. There is a
small, but non-zero, chance of thunderstorms over Arizona sending
gusty south to southeast winds into the Valley overnight. Stronger
winds are expected Sunday, with southerly winds increasing to 10 to
15 knots with gusts 20 to 25 knots in the afternoon. No
operationally significant clouds are expected through the period.

For the rest of southern Nevada, northwest Arizona and southeast
California...Winds of 15 knots or less are expected across most of
the region today, with directions following usual diurnal patterns.
There is a chance of thunderstorms over Arizona sending gusty south
to southeast winds into the region overnight, with the greatest
chances in areas southeast of Interstate 15. Stronger southerly
winds are expected areawide Sunday, with gusts of 20 to 25 knots
common. Chances for thunderstorms will also be increasing over
Mohave County, with the main threats being gusty winds, briefly
heavy rain, and terrain obscuration. Dry weather is expected in
southeast California and southern Nevada.
&&

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