Area Forecast Discussion

830 PM PDT Sat Jun 30 2018

.SYNOPSIS...Expect dry weather conditions and temperatures right
around normal through much of next week before high pressure builds
in from the east bringing increasing temperatures heading into next
weekend. More humid conditions are possible in Mohave County by the
end of the week as higher moisture is directed towards the area from
the southeast.
&&

.UPDATE...Mostly clear skies exist across the region today with
temperatures today topping off pretty close to seasonal normals. Did
get some reports of smoke/haze across the Mohave Valley and parts of
Northwest Arizona which appears to have advected in from fires in
Southwest Utah.  Some of this thin smoke layer will linger overnight
across areas mainly south of I-15.   The current forecast looks good
and no updates are planned this evening.

.DISCUSSION...Another day of quiet weather across the region today
with expected highs falling just short of normal, light winds and
abundant sunshine. Ditto for Sunday except we should see high
temperatures climb a few degrees above normal. Temperatures level
out Monday before falling back to normal Tuesday and on the July 4th
holiday. There will be a better chance of seeing increasing breezes
Monday and Tuesday afternoon with lighter winds returning for the
4th.

Models are generally in good agreement that increasing moisture to
our southeast will be directed towards our area next weekend. A
combination of high pressure over the intermountain region and an
inverted trough moving westward is forecast to bring higher moisture
and increasing instability to the area. The official 7-day forecast
still looks dry but models are forecasting enhanced southeast winds
and higher surface dewpoint temperatures into Mohave County on
Friday across. If model trends hold, this could be the first
good push of monsoon moisture into the region.
&&

.AVIATION...For McCarran...Typical diurnal winds are expected
tonight and Sunday, with south winds around 10 kts at night and east
to southeast winds 5 to 10 knots during the afternoon hours. No
weather or significant clouds expected.

For the rest of southern Nevada, northwest Arizona and southeast
California...Generally quiet weather is expected through the rest of
the weekend, with winds under 20 knots. Aside from a slight chance
of thunderstorms over the Sierra crest Sunday afternoon, no weather
or significant clouds expected.
&&

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

DISCUSSION/AVIATION...Salmen
