Area Forecast Discussion
National Weather Service Las Vegas NV
216 PM PDT Sun Sep 10 2017

.SYNOPSIS...Shower and thunderstorm activity through mid-week
will be limited to mainly southeast California and the higher
terrain of the southern Great Basin and northwest Arizona. Winds
will begin to increase Tuesday and Wednesday afternoons as a low
pressure system moves into the region. This will signal a possible
change to a more fall-like weather pattern late this week with drier
and occasionally breezy conditions.
&&

.SHORT TERM...through Wednesday night.

Much calmer day than what we have seen the past two days. Heading
into this evening. Operational HRRR as well as the HRRRx have been
consistent showing isolated showers/thunderstorms over eastern
Mohave County into this evening before storms dissipate by 8 pm this
evening.

For Monday-Wednesday. Closed low presently well off the southern
California will be feature of interest. The low is progged to start
drifting back north off the the central California tonight-Monday,
then remain nearly stationary off the central California Coast
through Tuesday. Low finally starts to fill/open up and move inland
Wednesday in response to deeper low digging into the Pacific
Northwest. NAEFS PW standardized anomaly data shows a slight
increase in PW values in western Inyo County Monday/Tuesday.
Elsewhere, don't see any new injection of moisture from the south so
trough will being acting on moisture currently in place. Broad area
of modest instability areawide along with ascent associated with the
upper low will generate scattered showers/thunderstorms primarily
focused in Inyo County Monday and Tuesday. With additional dynamics
provide by the upper low do expect a few showers and thunderstorms
to persist through Monday night and Tuesday night. Better dynamics
start to shift east into southeast Nevada and northwest Arizona
Wednesday. May see some showers/thunderstorm last through Wednesday
night in northern Mohave County, otherwise drier air will start
sweeping in from the west Wednesday night. South-southwest breezes
will be a tad stronger each day while temperatures hover near
seasonal normals.

.LONG TERM...Thursday through Saturday.

The Upper-Level low will continue to open up and eject out of the
area on Thursday, leaving a breezy afternoon with below normal
temps. A mean trough will remain in place over the region through
the weekend with rather pleasant conditions for most as temps
continue to run a few degrees below normal with afternoon breezes.

A tropical system is forecast to develop south of the Baja Peninsula
over the next few days. Current forecasts keep the system well south
of the area, with sheared remnants and moisture remaining well to
the east of the area under zonal to southwest flow.

If current forecasts remain in place, Las Vegas may well have
already seen the last 100 degree day of 2017. With a more fall-like,
trough-ridden pattern, expect temperatures near or just below
normal. The average last 100 degree day in Las Vegas is September
16. 100 degree highs have occured as at as October 4 (1947).
&&

.AVIATION...For McCarran...East-northeast wind up to 10 kts into
early evening, then decreasing as winds will return to a west or
southwest direction overnight. Winds on Monday will start out
easterly but we may see the direction want to sway more from the
southeast in the late afternoon. Isolated showers/storms will be
possible, mainly over the Spring Mountains and in the Beatty and
Daggett corridors Monday.

For the rest of southern Nevada, northwest Arizona and southeast
California... North or an easterly winds at 5-15 kts in most areas
this afternoon. A few showers/storms will be possible, mainly across
NW Arizona. Similar conditions are expected Monday. CIGS with shower
activity will mainly be in the 7-11 kft range.
&&

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