.DISCUSSION...

Hot and generally dry weather continue this weekend. Skies are
mostly clear as this morning with some cumulus development in the
southern portions of the CWA. We are currently seated under a sort
of dry slot between an upper ridge to our east and an upper low
off the PacNW. The ridge to our east is dirty with trapped
moisture under it, which will lead to showers and isolated
thunderstorms in portions of Mineral and Mono each afternoon this
weekend per the HREF members. Main concerns with any storm will be
gusty outflow winds to 35-40 mph, brief periods of heavy rain and
dry lightning outside of rain cores. Furthermore, this set up
allows for stronger afternoon winds compared to the last few days,
especially for the Sierra Front and NE CA with gusts generally
between 25-35 mph and isolated gusts up to 40-45 mph over mountain
ridges. This will lead to minor impacts to aviation and
recreational interests, as well as critical fire weather
conditions in the aforementioned areas. More of this in the Fire
Section below. Temperatures this weekend will be seasonably hot
with temps in the upper 90s to around 100F in valleys of western
NV and NE CA, higher elevations including Sierra communities will
be in the 80s.

A similar pattern continues next week with the upper high moving
towards the Southern Plains, and the upper trough becoming deeper
to our west, and leading to a looser the pressure gradient over
our region. Therefore, typical afternoon winds return along with
drier conditions, POPs below 5%, and high temperatures around 5
degrees cooler than this weekend. For the second half of the week,
the upper high retrogrades back towards the Desert Southwest.
Main hazard at the moment will be heat. Temperatures climb back up
late next week into the upper 90s and around the triple digit
mark for all valleys. There is a 75-90% chance of reaching 100F
next weekend per NBM guidance if this weather pattern persists.

.AVIATION...

VFR conditions prevail through the next 24 hrs. Exceptions
possible near KMMH and KHTH due to a 10-30% chance of -SHRA/-TSRA.
Otherwise, dry weather prevails. Winds will be the main concern
with W to SW gusts to 25-30 kts. Minor turbulence and LLWS is
possible between 00Z and 18Z Saturday due to FL100 SW winds around
30 kts.

.FIRE WEATHER...

Enhanced zephyr breezes with gusts up to 35 mph (isolated gusts
up to 40 mph) today through Saturday will create 3 to 6 hours of
Red Flag conditions in the afternoon and evening hours across
portions of northeast CA and western NV. They also overlap with
the Biscar Fire and the new Macy Fire in northern Washoe County.
These winds will coincide with minimum RHs of 5-15%, with
overnight recoveries 20-45% over the aforementioned areas.

Elevated to critical wind/RH is possible Sunday afternoon in
similar areas. A Fire Weather Watch was issued to address this
potential fire threat. After Sunday, high pressure with a dry
airmass will move overhead, with afternoon winds returning back to
our typical breezes (10-15 mph gusting 20-25 mph).
