Area Forecast Discussion
National Weather Service Reno NV
224 PM PDT Wed Jun 20 2018

.SYNOPSIS...

Above average temperatures with dry conditions will prevail
through next week. Breezy afternoon and evening winds are
expected through Thursday, with lighter winds Friday and
Saturday. Thunderstorm risks remain very low through next week.

.DISCUSSION...

Weak upper low continues to move through northern CA tonight with
breezy winds across the region through the evening hours. Very
warm temperatures continue for the next several days, with high
temperatures around 10 degrees above average for late June. Hot,
dry and breezy conditions will lead to elevated fire weather
conditions today and tomorrow. See fire weather discussion below
for more details. Breezy conditions are expected again for
Thursday afternoon, although not quite as breezy as today. Very
dry air aloft will mix down tonight and into Thursday, leading to
afternoon humidity down into the single digits.

This hot and dry pattern will remain in place through the middle
of next week, with temperatures in western Nevada remaining in the
mid 90s. Temperatures in the Sierra will be very warm too, with
70s/80s in the higher elevations. Typical afternoon zephyr breezes
can be expected each afternoon/evening. No thunderstorms are in
the forecast through next week, as we remain in a dry west-
southwest flow that will keep any moisture from creeping up the
Sierra. -Hoon

.AVIATION...

VFR conditions through the end of the week with increasing
Southwest winds this afternoon and evening with peak gusts around
25kts. Breezy winds expected tomorrow as well, with gusts up to
20kts. Light turbulence possible through Thursday evening. -Hoon

&&

.FIRE WEATHER...

Afternoon breezes and a very dry airmass are leading to some low-
end fire weather concerns for this afternoon/evening and tomorrow.
Of the two days, today will be breezier with gusts in the upper
20s to around 30 mph along the Highway 395 corridor north of
Bridgeport with around 25 mph out to the Highway 95 corridor.
Minimum humidity values drop to around 10%. Localized critical
conditions will be possible for the usual wind prone locations.
The period of strongest winds will occur after 1600-1700 this
afternoon and be relatively short-lived. Most of the rest of this
afternoon and evening will otherwise be gusting 20-25 mph.

Best overnight recoveries will occur by 0200 then drop through
the rest of the day to around 5% for many western Nevada locations
and around 10% for Sierra valleys on Thursday. Conditions for mid
slope and ridges tonight will also be very dry due to the
incoming dry slot. The zephyr for tomorrow will be a little weaker
with gusts 20-25 mph in general.

Poor humidity recoveries, single digits to 15% afternoon humidity,
and periods of breezy conditions will continue into next week.
Saturday may have some localized critical conditions occur mainly
in 453/458 zones with northerly flow. Then, more typical westerly
afternoon winds may be slightly enhanced early next week. The good
news is that thunderstorm chances remain minimal due to an east-
west oriented ridge axis keeping monsoonal moisture well south and
the northerly position of the storm track keeping migratory
systems displaced well northward in the Pacific Northwest and
Canada.

Otherwise, unseasonably warm temperatures and low RH will favor
further curing of fuels. We`re approaching the tipping point
where fuels will be ready to go on a more widespread scale;
estimates for early July appear to be on track. Boyd
