.DISCUSSION...

Hazy conditions, carrying over from the morning, will slowly
dissipate today with the return of typical zephyr breezes (gusts
up to 20-25 mph). However, with fires continuing in northern CA
and southern OR, expect hazy conditions to continue overnight and
into the morning hours this weekend. To check air quality, visit
www.fire.airnow.gov.

The main story will be an ongoing heat wave through early next
week. Locations across the area will see the hottest temperatures
of the year so far; far W NV valleys seeing highs up to 105
degrees, the Quad Counties area experiencing 98-104 degrees,
Sierra communities in the low 90s, and locations in NE CA pushing
103 degrees. Reno will see its first 100 degree day of the year so
far as early as Saturday, with a 75% chance of exceeding 100
degrees. We could also near record-breaking territory Sunday; the
forecasted high for Reno is 102 while the record, set in 2014, is
103 degrees.

Areas of widespread Moderate HeatRisk Saturday will quickly evolve
into Major HeatRisk by Sunday as afternoon highs peak Sunday and
Monday across the area. Isolated areas of Extreme HeatRisk are
possible both Sunday and Monday, primarily in W NV valleys east
of Fernley. Heat recoveries will be poor, with overnight lows
pushing the upper 60s and low 70s for W NV this weekend, bringing
little overnight relief.

Besides typical afternoon zephyr breezes, winds will be light.
With the increase in heating this weekend, there will also be
increased instability. The next best chance (<10% chance) for
afternoon showers and thunderstorms will be next Tuesday through
Friday. Stay tuned for more details as we get closer.

.AVIATION...

VFR conditions prevail, but areas of haze or smoke may impact far
northwest Nevada and northeast California, especially near the
CA/OR border through this weekend. Otherwise, SW winds gusting
20-25 kt each afternoon, coinciding with the afternoon zephyr.

Density altitude conditions will become increasingly hazardous
Sunday through Tuesday due to elevated temperatures and high field
elevations. Expect reduced aircraft performance during peak heat,
particularly for high-elevation takeoffs and landings.
