Area Forecast Discussion
National Weather Service Las Vegas NV
934 AM PDT THU SEP 1 2016

.SYNOPSIS...Scattered showers and thunderstorms will develop
primarily over northwest Arizona today through Friday while a few
storms may brush southeast Nevada today. The rest of the region will
experience dry and breezy conditions with a slight cooling trend.
A dry southwest flow associated with a broad area of low pressure
will persist over the Labor Day weekend with temperatures cooling a
little below normal through early next week.
&&

.UPDATE...First batch of storms looks like it should be mostly out
of our CWA around 18Z, with more new development expected this
afternoon. Grids look representative and no update planned this
morning.
&&

.PREV DISCUSSION...
325 AM PDT THU SEP 1 2016

.SHORT TERM...Through Friday Night.

It appears things are shaping up to favor thunderstorms primarily
over northwest Arizona today though some isolated showers or
thunderstorms could develop over eastern Lincoln/northeast Clark
counties and the Spring Mountains and Sheep Range. Recent
mesoanalysis charts showed a tongue of PWAT of 1-1.25 inches
extending up across northwest AZ and far southeast CA/NV. There has
obviously been broad upward forcing with extensive cloud cover
developing over Mohave County overnight due largely to convergent
mid level flow and a curved upper level 60-70 knot jet which will
remain in place through the day. Forecast soundings indicate a
moderately unstable vertical profile under the aforementioned areas
of moisture and we should see scattered thunderstorms result over
much of Mohave County. Storm motion will generally be to the north-
northeast 15-20 mph. Convection should continue well into the
evening hours given the upper level dynamic support.

The moisture boundary is forecast to only push slightly eastward
through Friday and should still remain over the eastern half of
Mohave County keeping the chance of thunderstorms confined to that
area through Friday afternoon and early evening. The rest of the
region will see dry and breezy conditions with temperatures dipping
back to normal values as the broad west coast trough progresses
slightly inland.

.Long Term...Saturday through Thursday.

A hint of autumn will be in the air during the extended period as a
rather large trough is carved out across west keeping our region
"cool" (By early september standards) and breezy.  Afternoon high
temperatures over the labor day weekend will average 4 to 8 degrees
below calendar day normals.  In addition to the cool temperatures,
thermal gradients across the Great Basin will induce fairly breezy
conditions especially across the Mojave desert, especially Saturday
and Sunday.  The combination of dry and breezy conditions may favor
elevated fire danger during this period.

Looking ahead into next week...dry conditions will continue with a
gradual return to near normal temperatures. Beyond Wednesday...a
tropical disturbance has been consistently advertised by forecast
models to develop in the vicinity of the Baja and move northward,
possibly inducing a moisture surge for the later portion of the
week. Tropical influences in the extended range are notoriously
fickle, so I have made few changes to the longer term grids at this
time, but it will be something to keep an eye on.

.AVIATION...For McCarran...Wind speeds will increase by late
morning with a south-southeast component becoming more decidedly
south by early afternoon with gusts of 20-25 knots through the early
evening. Thunderstorms can be expected primarily in the Peach Spring
corridor and in the Mormon Mesa corridor near the Utah border this
afternoon and evening.

For the rest of southern Nevada...northwest Arizona...and southeast
California...Gusty southwest winds will expand in coverage across
much of the region today. Isolated to scattered thunderstorms will
be confined to northwest Arizona and far southeast Nevada this
afternoon and evening.

.SPOTTER INFORMATION STATEMENT...Thunderstorms are expected to
return to the forecast for at least Mohave County today through
Friday. Spotters are encouraged to report significant weather
according to standard operating procedures.
