.DISCUSSION...

The peak of the heat has passed with many valley sites in the
advisory area seeing triple digit heat yesterday, including a tied
record high of 102 degrees at Reno airport for the date. Slow
overnight cooling and light winds will keep lingering effects in
some areas for the next few hours, so we`ll let the heat advisory
run its course. Today we`ll see a highs touching 100 degrees near
and east of US-95 in west central NV, but overall a cooling trend
will start to take place. Highs will dip below average by this
weekend, with upper 80s-lower 90s for most lower elevations and
mid 70s-near 80 for Sierra communities.

Thunderstorm activity today will shift to the south and east this
afternoon as drier southwest flow advances into more of the
region due to a trough reaching the west coast, while the high
pressure ridge retreats to the Four Corners region. The best
chances (20-40%) favor Mono, Mineral, southern Lyon and southeast
Churchill counties mainly between 2-7 PM, with potential impacts
including outflow wind gusts of 45+ mph, short bursts of heavy
rain and small hail, and lightning strikes that could ignite new
fires. A few showers and storms could return in eastern parts of
Mineral-Mono counties Thursday afternoon, but these chances drop
to 10-20%. Otherwise, dry conditions should prevail through the
upcoming week, although there`s a minimal (5-10%) chance for a
few afternoon showers near the OR border this weekend.

The other effect of this cooling and drying trend will be
increasing winds this afternoon. Current projections still show
potential for wind gusts of 30-35 mph overlapping with RH between
10-15% in parts of western NV for a couple of hours. This will
lead to elevated fire weather concerns, especially in areas
receiving lightning but little rain yesterday. More typical
afternoon breezes are then expected for the remainder of the week
and the weekend. However, the location of the trough near the west
coast could edge a bit closer and bring increased wind gusts
similar to today for Saturday and/or Sunday. MJD

.AVIATION...

Shower and thunderstorm chances shift mainly to Mono-Mineral
counties this afternoon, with 10-20% chance of a storm near KMMH
between 20-23Z, but better storm chances are likely to remain
farther east. For the other main terminals, no storms are expected
but west winds will increase with gusts 25-30 kt mainly between
21-04Z, except starting and ending a couple hours earlier for
KTRK-KTVL. These winds will likely produce low-end turbulence and
LLWS impacts today for flights in/out of the main terminals.

VFR conditions with afternoon wind gusts of 20-25 kt are then
expected for the reminder of this week at the main terminals. MJD
