Flash Flood Warning 1, NWS Reno, NV

Area Forecast Discussion
National Weather Service Reno NV
154 AM PDT Thu Jun 23 2022

.SYNOPSIS...
Summer temperatures along with thunderstorm chances will stick around
the rest of the week into the weekend. Plan on temperatures about
5 to 10 degrees above normal. Monsoon moisture migrating into the
region will bring thunderstorms this afternoon and evening, with
lower chances headed into the weekend.

&&

.DISCUSSION...

If you missed the memo, summer has arrived! Warm to hot
temperatures and the chances for thunderstorms will remain a
fixture in the forecast through the upcoming weekend. Got outdoor
plans? Let's be summer weather-ready. Have a way to either receive
weather alerts, have a backup plan or exit strategy, and be an
avid cloud watcher! You know when those cumulus clouds start
bubbling up, it's time to pack up and head on out.

TODAY:

* Monsoonal moisture along with a closed upper level low are
  certainly making their presence known the past 24 hours.
  Southern and Central CA have been contending with a prolific
  thunderstorm and lightning event! Over 56,000 lightning events
  were detected across CA since 4pm Tuesday, and there are still
  storms ongoing.

* PWATS are projected to surge into the 0.5-0.8" range for the
  eastern Sierra and western Nevada through today. This moisture
  paired with this low pressure system tracking into the region
  along with afternoon heat will be sufficient to produce
  thunderstorms and showers region-wide. Storm motions will be
  relatively fast with a bit higher of a threat for strong gusty
  outflow winds and dry storms (little to no rainfall). That being
  said, storms that form closer to the slower moving low center
  may linger long enough to produce very localized heavier
  rainfall totals. There is a risk for flash flooding in steep
  terrain and burn areas today, especially if a thunderstorm pops
  over just the "right" location. Thunderstorms appear to quickly
  dissipate by tonight as the upper level low quickly ejects
  eastward.

FRIDAY - SATURDAY:

*  High pressure returns across the region with continued warm
   temperatures in the 90s for western NV and 80s for the Sierra.
   Lingering moisture and surface heating will be enough the
   produce showers and thunderstorms Friday and Saturday.
   Thunderstorm coverage will be confined mainly to the eastern
   Sierra from Alpine county southward into Mono/Mineral counties.
   Typical late afternoon westerly breezes will push any storms
   that develop along the higher terrain eastward into western
   Nevada.

SUNDAY ONWARD:

* Thunderstorm chances drop off even more by Sunday and Monday as
  the ridge axis settles across the Sierra and western Nevada.
  Westerly zephyr winds continue in the afternoons with the drier
  southwest flow across the region. Sunday and Monday will be the
  warmest days with upper 90s with some triple digit heat in
  western Nevada. The heat doesn't appear to stick around as
  another trough is projected to drop into the Pacific Northwest
  Monday/Tuesday. Blended model guidance indicates the potential
  for a more breezy, but "cooler" (about 5-10 degree drop) period
  next week.

.AVIATION...

As of 1 am, some light showers were pushing across the Interstate 80
Highway 50 corridors this morning.

Typical westerly afternoon breezes with gusts up to 25 kts this
afternoon and evening for western NV terminals. Plan on isolated to
scattered thunderstorm coverage today as monsoon moisture combines
with afternoon heat and an upper level low to put on a show.

* 15-20% chance of isolated thunderstorms for W. NV
* 25-40% along the E. Sierra.

Increased risk for moderate low-level turbulence, gusty and erratic
outflow winds up to 45 mph, lightning, and localized heavy
rainfall. Patchy blowing dust from storm outflows could reduce
visibilities at KLOL-KNFL late this afternoon. Storms are
projected to dissipate by tonight. Thunderstorms will be confined
to the eastern Sierra Friday and Saturday (KMMH, KBDG, KHTH).

-Edan

.FIRE WEATHER...

* Based on information via our partners at the BLM/USFS, fuels
  remain in transition for most lower elevation areas. Critical
  fuels are not widespread enough to issue fire weather products at
  this time.

Thunderstorms are the main concern today as a surge of moisture
pushes into the region in conjunction with an area of low
pressure. The thunderstorm threat will spread to most areas
today, highest for areas near and south of I-80, and lesser
(~15-25%) chances north of there. With better moisture, anticipate
decent rains out of thunderstorm cores, but the risk for isolated
dry strikes remains, especially for areas north of I-80 which
will take longer to moisten up. We need to watch recent burn scars
for flash flood concerns if a strong thunderstorm lingers over
the wrong basin.

Thunderstorms have the potential to produce gusty and erratic
outflow winds in excess of 45 mph. Like Wednesday, some model
simulations are indicating large scale outflow winds pushing off
the higher terrain into western NV late this afternoon/early
evening. So there could be a 2-3 hour window of enhanced winds
15-25 mph with higher gusts along with blowing dust off the dry
sinks.
