east of Sutcliffe, or 10 miles southeast of Pyramid Lake, moving 
northwest at 35 mph.

HAZARD...60 mph wind gusts.

SOURCE...Radar indicated.

IMPACT...Expect damage to roofs, siding, fencing and trees. Strong 
         wind gusts expected to impact boaters along the south shore 
         of Pyramid Lake within the next 20 minutes. 

Locations impacted include...
Pyramid Lake, Nixon, Sutcliffe, Virginia Peak, The Needle Rocks, and
Tohakum Peak.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

For your protection move to an interior room on the lowest floor of a

Wind damage with this storm will occur before any rain or lightning.
Do not wait for the sound of thunder before taking cover. SEEK
SHELTER IMMEDIATELY inside a sturdy structure and stay away from
windows.

If on or near Pyramid Lake, get away from the water and move indoors 
or inside a vehicle. Remember, lightning can strike out to 15 miles 
from the parent thunderstorm. If you can hear thunder, you are close 
enough to be struck by lightning. Move to safe shelter now!  Do not 
be caught on the water in a thunderstorm.

Area Forecast Discussion
National Weather Service Reno NV
129 PM PDT Sun May 3 2026

.KEY MESSAGES...

* A weather system continues to bring showers, thunderstorms, and
  cooler temperatures today. Be prepared for recreation and
  travel impacts due to gusty winds, rain, hail, and mountain
  snow.

* Cool, showery weather with additional thunderstorm chances
  expected Monday and Tuesday. Snow may impact travel over mountain
  passes above 8000 feet Monday.

* Warm and dry weather returns mid-week.

.DISCUSSION...

Today: A Pacific closed low resides west of the Central CA coast
today. Forecast guidance keeps this low from making landfall today,
but has it moving closer to the coast throughout the day. At the
surface, showers and thunderstorms have already kicked off in
portions of the Sierra and Sierra Front according to the latest
radar returns. Shower chances for the rest of today look to be
around 30-50% in NE CA, 70-90% in the Sierra, 50-70% in the
Sierra Front, and 20-60% in the W NV Basin and Range. While the
entire region sees some risk for thunderstorms today, the Sierra
and Sierra Front portions have the best chances of 25-45% this
afternoon. Potential storm hazards today include lightning
strikes, small hail & ice pellets, erratic & gusty winds, and
brief periods of heavy rain. Storm motion looks to be quick
(~15-25 kts to the N/NW), so this will lower potential flooding
concerns today. Severe thunderstorm chances do look low (<5%), but
cannot be ruled out completely as the latest RRFS run shows
convective parameters that could support it especially around the
Greater Tahoe area this afternoon. Please have a way to receive
the latest weather information especially if you have outdoor
plans for the rest of today. Area-wide precipitation chances look
to diminish to around 10-30% overnight with the exception of
portions of W NV south of US-50 which sees a 40-70% chance
continuing around midnight. Snow levels also will drop to around 8
kft overnight which will change precipitation type to snow in
higher portions of the Sierra. Higher elevations in Mono County
potentially have a 40-50% NBM probability of 1+ inches of snowfall by
Monday morning.

Monday and Tuesday: Model guidance has the aforementioned Pacific
upper low take a southwest track along the CA coast on Monday. The
low then begins a more eastward track staying south of the CWA as it
opens up into trough on Tuesday. With this pattern aloft,
precipitation chances will continue on Monday (60-90% across the
region) and Tuesday (20-60% along and south of I-80, around 20% or
less to the north). Thunderstorm chances for Monday afternoon
look to be around 20-30% areawide with Tuesday seeing the same chances
along and south of I-80 and <15% to the north. Similar storm
hazards to those on Sunday will be seen on both days with severe
potential (storms containing 58+ mph wind gusts and/or large hail
of 1+ inches in diameter) being low, but still possible. Remember:
when thunder roars, go indoors. Area high temperatures cool down a
bit on Monday (NE CA and W NV valleys in the middle 50s to middle
60s range, Sierra Communities in the upper 40s) before rebounding
a bit on Tuesday. Another concern is the potential for mountain
snow at some of the Sierra Passes in Mono County as snow levels
look to drop to around 7.5-8 kft during Monday and then down to
around 7 kft overnight Monday. This may allow for accumulating
snow at recently open Sierra Passes that could cause some
hazardous traveling conditions. While the high sun angle at this
time of year may inhibit some of the accumulation, the latest NBM
probabilities show around a 45-65% chance of 6+ inches of snowfall
at the Sierra Crest in Mono County by late Tuesday morning. As
active weather expects to continue into the first half of the
week, please watch for forecast updates as they become available.

Wednesday and beyond: As the trough is absorbed into a larger trough
out in the E CONUS, an upper ridge moves over the W CONUS starting
Wednesday. This ridge looks to be part of an omega blocking
pattern through much of the rest of the work week. This will allow
for dry conditions to prevail for the rest of the week with
temperatures warming to around 5-10 degrees above seasonal
normals. Currently, NE CA and W NV valleys have highs forecast in
the lower to middle 80s while Sierra communities have daytime
high temperatures in the 70s beginning Thursday and going though
the weekend. There is some model uncertainty in the upper air
pattern over the weekend though as the GEFS shows a weak trough
moving through the NW CONUS while the ECMWF Ensemble shows this
feature being merging with a trailing Pacific low. While the dry
pattern and the above normal temperatures expect to continue over
the weekend, the GEFS solution may result in a slight uptick in
winds though there is low forecast confidence at this time. -078

&&

.AVIATION...

Showers and thunderstorms continue within the region today. Most
area TAF sites see around a 30% chance for a thunderstorm to occur
through 04/03Z which would cause IFR conditions. The exception is
at KMMH which would has similar -SHRA chances bringing MVFR
restrictions during this time. Potential hazards with these storms
include frequent lightning, brief heavy rainfall, gusty outflow
winds around 35 kts, and small hail (less than one inch in
diameter). Severe thunderstorm chances are low today (<5%), but
are still possible (storms with gusts up to 60 mph and/or large
hail of one inch in diameter). Shower chances lessen overnight,
but increase again in the morning as more shower and thunderstorm
chances are in the forecast on Monday and Tuesday. Lower cloud
heights are expected today, which may cause mountaintop
obscurations. -078
