Area Forecast Discussion
National Weather Service Las Vegas NV
210 PM PDT FRI MAY 27 2016

.SYNOPSIS...Temperatures over the holiday weekend will edge
closer to normal for late May with a chance of afternoon and
evening thunderstorms primarily over the higher terrain of the
southern Great Basin and Mojave Desert. Elsewhere, mostly sunny to
partly cloudy skies are expected. Above normal temperatures will
develop by the middle of next week with the first bout of widespread
triple digit heat across the Mojave Desert.
&&

.SHORT TERM...Today through Sunday.

Weak troughing developing and moving in from California will linger
across the area through the holiday weekend. This troughiness does
look to bring an increase in moisture, creating at least some
chances of showers or storms for a good portion of the area,
especially around mountains. However, with moisture on the low end,
and with no real dynamics/forcing to contend with, having trouble
bumping POPs up due to uncertainty in occurrence in addition to
timing and placement. Areas in the northern half of the CWA in
addition to mountains in the southern half stand the best chance of
seeing a shower or two over the course of the extended weekend.
Temperatures will be near normal, so the only other sensible weather
will be southerly breezes during the afternoons of Friday and
Saturday, though speeds still look rather light.

.LONG TERM...Monday through Friday.

There remains a chance of isolated showers and thunderstorms across
mainly the higher terrain of northern Inyo, Esmeralda, central Nye,
and Lincoln counties to round out the holiday weekend. Then the
focus will shift to a pattern change that will swiftly bring dry
conditions and much warmer temperatures. Strong high pressure will
work into the western CONUS next week. Temperatures are expected to
be near normal Monday, but then quickly warm to roughly 5-10 degrees
above normal Wednesday through Friday. The heat might even linger.

.AVIATION...For McCarran...No significant weather expected with VFR
conditions and light winds following typical diurnal trends through
tonight. Sustained southeast winds up to 12kts...periodic gusts up
to 20kts possible after 20z Saturday.

For the rest of southern Nevada...northwest Arizona...and southeast
California...No significant weather expected with light winds
following typical diurnal trends for most terminals through the
period. The exception could be KBIH late Saturday afternoon into the
early evening when shower/thunderstorm outflow may impact the
terminal. Otherwise, shower chances will be limited to the higher
terrain of the southern Great Basin and Sierra Nevada with perhaps
another chance of breezy west winds at KDAG during the tonight.
