.DISCUSSION...

Dry southwest flow prevails over the Sierra into western NV, which
contributed to a cooler night in most areas, but also low humidity
already down to near or below 10% across areas of western NV. This
afternoon we`ll be in between shortwave passages, resulting in
wind gusts a little lower than yesterday, mainly 25-30 mph and
similar to typical zephyr breezes.

The next shortwave moving inland across southern OR late tonight-
Friday will be accompanied by a notable increase in mid-upper
level winds, with surface gusts also increasing to 30-40 mph and
mixing down about 2-3 hours earlier in the day, compared to
typical zephyr events. A Lake Wind Advisory has also been issued
for Friday including lakes in far western and west central NV.
Overall, Friday is standing out with the most widespread potential
for critical fire weather conditions, for more details see the
Fire Weather section below.

For this weekend into early next week, breezy to gusty afternoon
winds are again in the mix, although latest guidance showed a
slight downward trend in speeds Saturday. There could be an uptick
in wind speeds again Sunday and/or Monday, but confidence is
lower with more varied locations/tracks of an additional weak
shortwave moving through the SW flow pattern. Winds then look to
ease up on Tuesday but may trend upward by later next week.

Warm days a few degrees above average but not too unusual for
mid-June, with mild nights even a bit on the cool side for Sierra
and rural valleys, will prevail through early next week. Blended
guidance continues to bring in a signal for some warming by mid-
late next week, although some of the ensemble clusters don`t show
much amplifying of a high pressure ridge over CA-NV. At this time,
highs could creep back up to the lower-mid 90s for lower
elevations and slightly warmer for the US-95 corridor, and lower-
mid 80s for Sierra communities by next Wednesday-Thursday. Other
than a minimal 5-10% possibility of a few stray showers near the
OR border Monday, precip chances look to be absent for the
upcoming week. MJD

.AVIATION...

*  Winds will be the main aviation impact, with SW-W gusts near
   25 kt for far western NV terminals southward to KMMH, and near
   20 kt for KTVL/KTRK through 03Z this evening. For Friday, these
   winds could start to mix down about 2-3 hours earlier in the
   day (17-19Z) and linger 1-2 hours later into the evening (thru
   03-05Z), with gusts 25-30 kt and possibly near 35 kt for the
   far western NV terminals. Periods of mountain wave turbulence
   and occasional LLWS are anticipated for the next few days.

*  Widespread VFR conditions prevail for the next few days. Clear
   skies prevail over the main terminals through Friday morning,
   followed by a mix of flat PM cumulus/lee side mountain wave
   clouds and bands of cirrus Friday afternoon through this
   weekend. MJD

.FIRE WEATHER...

We upgraded the initial watch to a Red Flag Warning but only in
effect for Friday from late morning-late evening, as the overall
trend favored the stronger and longer duration winds Friday,
followed by lesser winds Saturday. We`re keeping an eye on Sunday-
Monday for a potential return of increased wind gusts, but current
guidance sources aren`t in very good agreement with the timing,
track and location of the next upper level feature that could
produce these enhanced winds. Humidity values will be quite low,
especially in far western and west central NV where afternoon
minimums will be in the single digits, with poor overnight
recoveries to less than 35%.

While we aren`t including today or Saturday-Monday in the warning,
expect shorter periods of elevated to locally critical fire
weather conditions with breezy winds and low RH each afternoon.
There remains potential for a few flare-ups of holdover lightning
ignitions from recent days. After recent fire activity around the
Reno-Sparks metro area, heightened awareness is advised on a daily
basis. MJD
