What forecasters said that day

The local office's own words before this red flag warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Reno, NV wrote its last area forecast discussion before this red flag warning went out at Jun 24, 1:55 AM PDT, 10 hours 9 minutes earlier. Its key messages:

  • * Warm with breezy afternoons through Thursday. * Gusty winds with a strong cold front on Friday & Saturday. Elevated fire weather concerns for W.Nevada. * Temperatures cooling 10-20 degrees below average over the weekend with light showers possible.
Area forecast discussion, Jun 24, 1:55 AM PDT, 10 hours 9 minutes before
Area Forecast Discussion
National Weather Service Reno NV
155 AM PDT Wed Jun 24 2026

.KEY MESSAGES...

* Warm with breezy afternoons through Thursday.

* Gusty winds with a strong cold front on Friday & Saturday.
  Elevated fire weather concerns for W.Nevada.

* Temperatures cooling 10-20 degrees below average over the
  weekend with light showers possible.

&&

.DISCUSSION...

Temperatures dip 2-3 degrees today but will remain seasonably
warm through Thursday with highs in the low-to-mid 90s across
western Nevada with upper 70s to low 80s for Sierra valleys.
Afternoon cumulus will once again develop across elevated terrain,
some may be deep enough to pop a few light showers (15% chance)
across N.Lassen/N.Washoe counties this afternoon. Otherwise very
dry conditions with late afternoon zephyr winds will prevail with
gusts of 20-25 mph this afternoon, increasing to 20-30 mph by
Thursday afternoon.

A major pattern change is expected this weekend as an unusually
strong cold front (by June standards) sweeps through much of the
Great Basin. This front will take us from being about 10 degrees
above average to around 20 degrees below average by Sunday which
means we can expect strong winds in between. In general, we are
looking at widespread 20-50% chances to see wind gusts over 40
mph across the E.Sierra and W.Nevada on Friday and Saturday with
Saturday showing stronger sustained wind potential around 20-30
mph as surface gradients tighten with the arrival of the front.

Fire weather concerns will be at the forefront for western Nevada
as these areas will see the best combination of strong winds, low
humidity, and dry fuels. Fire Weather Watches remain in effect for
Friday and Saturday. See the Fire Discussion below for additional
details. In addition to fire weather concerns, winds could
disrupt outdoor recreation, create hazardous boating conditions,
and impact road and aviation travel. High profile vehicles could
be impacted by strong crosswinds, and blowing dust may reduce
visibility in areas downwind of desert sinks.

Precipitation will mainly concentrate along the cold front
Saturday into early Sunday morning. Showers chances will largely
remain northward of I-80 with a 10-20% chance of seeing up to
0.10" of rainfall with 30-50% odds for areas across N.Lassen
County into the Surprise Valley/far N.Washoe County. Snow levels
will fall to around 7000-8000' from the Tahoe Basin to the Oregon
border which means light snow showers are not out of the question
for higher elevations of the N.Sierra and Warner mountains.

The airmass behind the front has temperatures of around -4C at
700mb which is near observed minimums for the date. This means
our temperatures will fall to around 15-20 degrees below late June
averages Saturday and Sunday. While not cold so to speak, highs
in the lower 70s for this time of year have a 75% chance of
setting record cold high temperatures on Sunday. Sierra valleys by
Sunday morning could see 60-70% odds of overnight lows falling
below freezing. Even Carson Valley communities could see a 20-25%
chance hitting the freezing. Fuentes

&&

.AVIATION...

* VFR conditions with typical west/northwest breezes each afternoon
  with gusts around 20-25 knots, increasing to 25-30 knots by
  Thursday afternoon.

* A strong cold front Friday and Saturday will produce strong and
  gusty winds across the E.Sierra and W.Nevada terminals. Gusts of
  30-40kts will be possible along with increased likelihood of
  mountain wave turbulence, LLWS, and areas of reduced visibility
  due to blowing dust mainly around KLOL, KNFL, and KHTH. Fuentes

&&

.FIRE WEATHER...

* Unusually strong cold front for late June projected to bring
  areas of critical fire weather conditions Friday and Saturday.
  Fire Weather Watches remain in effect for the Sierra Front
  eastward into the Hwy 95 corridor.

* High confidence in seeing sustained winds 20-30 mph with gusts
  above 40 mph both days, W/SW direction on Friday and W/NW on
  Saturday. Saturday's winds may end up being more of a sustained
  wind concern versus just the gusts. Almost an April-like pattern
  in late June.

* For areas in the watch along and north of a Carson City to
  Lovelock line, including Reno, the humidity may be just above
  RFW criteria, around 15-25% for afternoon minimums. But with
  plenty of dry fuels/grasses and recent significant lightning
  event last Friday with holdover potential, winds of this
  magnitude may lessen the impact of slightly higher RH.

* E.Sierra fire weather zones are also expected to see these same
  strong winds with ridgetops seeing wind gust potential exceeding
  80 mph. However, fuels have not been reported to be critical and
  minimum RH is expected to be around 30-40%. However, the
  exception could be along Hwy 6 and 395 below 7000' in Mono
  County where RH could dip into the teens.

* Humidity recoveries Friday night into Saturday morning look
  good (45-75%), but winds will remain breezy for mid-slopes and
  ridges.
