Area Forecast Discussion
National Weather Service Reno NV
105 PM PDT Sat Jun 25 2022

.SYNOPSIS...

Showers and thunderstorms to continue through this evening. These
could produce gusty outflow winds, brief heavy rainfall, and
deadly lightning strikes. Hot and drier conditions are on tap for
Sunday and Monday. A slight cooling trend begins Tuesday along
with breezier winds and continued dry conditions through the
upcoming work week.

&&

.DISCUSSION...

Showers and thunderstorms have formed as expected this afternoon,
with activity continuing through around sunset. With hot and dry low
levels, storms have the potential to produce gusty outflow winds in
excess of 40 mph and blowing dust is possible. Effective storm
motion will be around 10-15 kts, which is slower than what we saw
this past Thursday, but PWATs are also lower, so it may end up
being a wash in terms of rainfall. Anticipate brief heavy rainfall
under thunderstorm cores, however, overall QPF amounts will be
spotty. We will need to monitor burn scars, but the threat for
debris flows/flooding is low (less than 10%) this afternoon. Dry
lightning strikes outside of thunderstorm cores are also possible.

A building ridge over the west will push high temperatures 5-10
degrees above normal through Monday. With mid-afternoon temps
pushing the century mark in lower valleys Sunday and Monday, it may
be a good idea to keep outdoor activities limited to the morning or
evening hours. Otherwise, take frequent breaks out of the sun and be
sure to drink plenty of water. As mid and upper levels warm it will
cap thunderstorm development, so while a few cumulus buildups are
possible, thunderstorms are not expected.

An approaching trough off the Pacific Northwest coast will bring
an enhanced afternoon westerly zephyr wind the first half of next
week, likely peaking on Tuesday with gusts to around 35 mph. This
will correspond with a very dry air mass, bringing fire weather
concerns. Please see the fire section below for additional
details.

Ensemble clusters suggest the pattern will remain rather stagnant
next week with general troughiness along the west coast. This
will keep temps near normal, and dry, southwesterly flow over the
region. We'll see typical SW-W afternoon breezes each day, gusting
20-30 mph. -Dawn

&&

.AVIATION...

Thunderstorms have already fired off this afternoon from KMMH-KTVL.
Storms will push north and eastward into the latter part of the
afternoon and early evening. Timing for storms to be in the vicinity
of KRNO/KCXP/KMEV will be approx 22z-02z, and could reach as far
north as KSVE and eastward, including KHTH, and KNFL, through 04z.

Storms may produce brief heavy rainfall, obscuring terrain, in
addition to gusty and erratic outflow winds in excess of 35 kts.
Winds may kick up dust, reducing surface visibility.

Outside of storms, SW-W surface winds will gust 15-20 kts this
afternoon, and similarly on Sunday afternoon.

There will be some cumulus buildups on Sunday, but thunderstorms are
not anticipated. -Dawn

&&

.FIRE WEATHER...

Thunderstorms have once again formed today with storms being a
hybrid of wet and dry. Gusty and erratic outflow winds in excess
of 40 mph remain possible with the storms and wetting rains will
likely be limited to storm cores. Storms will continue through
approximately sunset this evening.

A warming trend will be on tap, but will only peak for a couple days
before returning closer to normal Tuesday onward. This may further
cure fuels, but from information from fire parters, fuels are
[currently] still not considered critical in a large enough area to
need fire warnings.

While afternoon winds speeds will be rather typical today and
Sunday, an uptick in SW-W afternoon winds can be expected next week,
in particular Tuesday. Wind gusts of 25-30 mph are expected each
day, with around 35 mph gusts Tuesday afternoon. This is
corresponding with a very dry air mass, single digit afternoon
humidities in lower valleys, and poor overnight humidity
recoveries. The dry and breezy conditions are certainly a concern,
and if there are any holdover lightning fires, could cause them
them flare up. -Dawn
