.SYNOPSIS...Isolated thunderstorms over the mountains will be
possible across the eastern Sierra and southern Great Basin through
Monday as a ridge of high pressure slowly pushes moisture to the
north. Thunderstorm coverage and intensity will continue to decrease
each afternoon as the region dries out and temperatures climb.
Dangerous heat will be in place early next week, and an Extreme Heat
Watch has been issued for portions of the Mojave Desert for Tuesday.
&&

.SHORT TERM...through Sunday night. Early afternoon satellite loop
showed cumulus clouds building on the higher terrain roughly north
of a line from Olancha to Las Vegas to Kingman. Thus far, the only
thunderstorms which have managed to develop have been in Lincoln
County, and these have been short-lived. Surface obs showed mostly
light winds with temperatures several degrees higher and dewpoints
several degrees lower than 24 hours ago. Weak low pressure off the
California coast will continue drifting slowly east through Sunday
night, producing weak southerly flow which will advect in drier air
from the south, very slowly drying us out from south to north. This
will keep thunderstorm chances confined to the southern Great Basin,
with slightly less coverage expected Sunday than today. The drier
air will allow temperatures to climb a few more degrees on Sunday,
leading to conditions which could be dangerous for anyone who is
susceptible to the heat or will be outdoors for extended periods.

.LONG TERM...Monday through Friday.

The work week will start off hot and dry as ridging maintains the
warming trend, which looks to peak Monday and Tuesday. Highs across
the region will be in the 90s and 100s for all but the mountains,
where temperatures will top out in the 80s - around 8 to 10 degrees
above normal. Monday and Tuesday will also see widespread Moderate
to Major HeatRisk, and an Extreme Heat Watch has been issued for
portions of the Mojave Desert for Tuesday. Those with outdoor plans
or who are vulnerable to the heat will need to plan accordingly.
After Tuesday, a pattern shift is expected as a trough begins
developing over the West Coast in response to a deepening low over
the Gulf of Alaska. Cluster analyses and ensemble guidance continue
to be in good agreement, keeping this system to the west of the
area, which will result in a transition to quasi-zonal or
southwesterly flow aloft midweek onward. This will allow for a slow
cooling trend as heights fall, though temperatures will still remain
above normal through the end of the week. There are also indications
of weak shortwaves rounding the base of the larger-scale trough, but
given the dry antecedent conditions, little will result from these
shortwaves beyond periodic breezy conditions across the region.
Overall, the pattern looks to be fairly quiescent through next week,
and a bit more on par with what`s to be expected in early to mid
June.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...Easterly
winds under 10 knots are expected through the day, although an
errant gust to around 15 knots cannot be ruled out. Winds should
turn back to southwesterly around sunset. Clouds will build up over
the mountains, possibly resulting in showers, but these are not
expected to affect the terminal. Similar weather is expected on
Sunday.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 18Z Forecast Package...Isolated thunderstorms
are expected this afternoon over the mountains of Lincoln, central
Nye, Esmeralda, and Inyo counties, and possibly reaching as far
south as the mountains of Clark and northern Mohave counties. The
main threats with these storms will be erratic gusty winds and low
ceilings with terrain obscuration. Away from storms, quiet weather
is expected with winds under 20 knots. Storms should die off shortly
after sunset. Similar weather is expected on Sunday.
&&

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