.DISCUSSION...

Cool, calm, and collected is the name of the game today! The only
exception may be along the Sierra crest from South Lake Tahoe down
to Mammoth where most hi-res solutions (minus the HRRR) are
highlighting light shower potential this afternoon. Otherwise,
expect highs in the low 70s and 60s for valleys and higher
elevations, respectively. Another cold morning on tap Monday
morning, with a ~45% chance for lows near or below freezing for
colder Sierra valleys.

Models have quickly resolved an insider-slider type low tomorrow,
which is a bit odd for late June. Anyhow, this closed low pressure
will bring additional upper level forcing, though the moisture
content is quite low. Shower and thunderstorm chances increase
along the Sierra tomorrow afternoon, with 100-300 J/kg MUCAPE from
Truckee down to the Mono/Inyo county border. PWATs are quite low,
though, only 0.3-0.4" at best. As such, expect any storms that
develop (10-15% chance) to be on the drier side.

The low pressure system that brought this weekend`s much cooler
temps will stall over the Great Basin this week, helping to keep
afternoon highs near or slightly below normal (mid 80s and low 70s
for W NV and Sierra communities, respectively) through midweek.
We will also see enhanced breezes by the middle of the week, with
the best chances for gusts to exceed 30-35 mph on Thursday for W
NV. With the pre-existing dry vegetation and low humidities,
elevated fire weather conditions are likely to emerge. Looking
further out, afternoon highs will increase to the low 90s for W
NV and low 80s for the Sierra for Independence Day.

.AVIATION...

VFR conditions for all terminals today. Afternoon cumulus build
ups after 21z are possible along the Sierra between KTVL-KMMH,
though chances remain below 15%. Any showers that develop may
bring localized mountain obscurations.

A second weather system arrives Monday with an increased chance
of showers and thunderstorms KTRK-KMMH 21z-03z Tuesday.
