.DISCUSSION...

So far this afternoon we're seeing a few cumulus buildups from
Mono County up through Lassen and northern Washoe counties.
Surface heating is currently priming the atmosphere for showers
and thunderstorms to initiate later this afternoon over far
western Nevada and northeastern California. More storms are
expected Wednesday and Thursday as well, with Friday being our
driest and coolest day of the week.

The storms this afternoon will have a decent amount of upper
level support from a broad area of divergence overhead due to a
low centered off the coast of SoCal. Convective initiation will
occur around 1 PM this afternoon and go through 8 PM. Chances
range between 15-20% in western NV and 25-35% in northeastern CA.
Today is a classic example where we'll see those inverted-V
profiles which means lots of dry air at the surface and potential
for strong outflow winds. DCAPE this afternoon for the Sierra
Front and northeastern CA will be around 1400-1700 J/kg, which
indicates thunderstorms could produce gusts up to 55 mph. The main
impacts from these thunderstorms today through Thursday include
gusty outflow winds, hail less than 0.50" in diameter, and
occasional lightning.

Much of the same on Wednesday except just a touch less
instability and increased storm coverage spreading east into Mono,
Lyon, and Pershing counties. The storms on Thursday will be more
concentrated to Lassen and far northern Washoe county, at a 20-30%
chance. Breezy zephyr winds are expected Thursday and Friday with
gusts up to 25-30 mph. This will lead to possible recreation
concerns on local lakes. See the Fire Weather section below for
more details on fire weather impacts.

The Fourth of July into early next week we start to dry out and
temperatures start to rebound back into the mid 90's by Sunday.
Friday's high temps get into the mid 80's in western NV and 70's
in the Sierra which is 5-10 degrees below average for this time of
year.

.AVIATION...

There's a 20% chance for showers and thunderstorms near
KMEV/KCXP/KRNO and a 10-15% near KTRK/KTVL/KMMH this afternoon
between 20Z-03Z. Primary impacts from thunderstorms include
gusty/erratic winds, small hail <0.50", and occasional lightning.

Typical zephyr breeze from the west today with gusts 15-20 kt at
all area terminals in the afternoon. However, near thunderstorms
there is a chance the outflows could produce gusts up to 50 kt.

-Justin

.FIRE WEATHER...

* Isolated hybrid storms today will produce lightning and strong,
  erratic outflow winds with gusts of 50+ mph. The best chances
  (20-40%) will be in Lassen, the Surprise Valley, and northern
  Washoe County. The Tahoe Basin generally north of Mono County as
  well as the Reno-Carson-Minden area will have around 15-25%
  chance for showers and storms, with 5-10% chances elsewhere.

* Shower and storm chances expand across much of the region on
  Wednesday. Once again, storms may produce lightning and strong,
  erratic outflow winds with gusts of 50+ mph. Locally heavy
  rainfall is possible inside storm cores.

* Brief 1-3 hour periods of localized critical conditions, mostly
  for western NV and inner-basin, by Thursday as breezy and dry
  conditions return. These dry conditions persist into the holiday
  weekend. -McKellar/Justin
