Synopsis
A cold front will continue to move through the region today with
gusty winds and significant cooling expected by Friday. Temperatures
will begin to warm again through the rest of the weekend and into
early next week. Another low pressure area, centered off the west
coast, will keep summer temperatures in check next week but also
bring several days of breezy winds.

Short term
A dry cold front is currently positioned across northwestern
nevada and will continue to move south through the sierra and
western nevada today. Gusty winds will accompany the front with
widespread gusts of 25-35 mph for most areas and localized up to
40 mph. This will create hazards for area lakes with lake wind
advisories in effect today. Localized fire weather concerns are
possible, see fire discussion below.

High temperatures this afternoon will run about 10-15 degrees
cooler roughly north of i-80 to the oregon border, but that will
still keep us right around season averages today. The front
should end our 10 day streak of highs in the 90s in reno with
highs in the mid-80s expected for western nevada (70s in sierra
valleys). Friday's highs will cool an additional 10 degrees with
mid 70s for w.Nv valleys and mid upper 60s for sierra valleys.

Temperatures near freezing are possible for colder sierra valleys
beginning tonight.

The cold front will move through mono county tonight and may yield
some gusty north winds in its wake, particularly over southern
mono and mineral counties. The chalfant owens river valleys will
likely see the strongest north winds. Winds shift northeasterly by
Friday with some choppy conditions possible on lake tahoe through
Friday evening. Fuentes

Long term Sunday onward...

temps warm to near normal by Sunday as a shortwave ridge briefly
builds into the west. Typical afternoon breezes will begin to kick
up again Sunday, further increasing the first half of next week, as
another trough drops along the west coast. This will keep the region
under dry southwesterly flow with temperatures near, then becoming
slightly below, normal. It also means that there will be enhanced
afternoon evening winds each day, which combined with the dry
conditions will bring fire weather concerns, contingent on fuels.

The strongest winds currently look to be on Tuesday, but Monday and
Wednesday (possibly Thursday) will also feature rather gusty
conditions.

Looking further out, ensemble guidance begins to establish a four
corners high by the very end of june or beginning of july -- fairly
typical given the time of year. However, there remains a trough over
the northwest, and based on most recent GEFS guidance, the ridge
doesn't expand as far west. This would lessen previous concerns for
possible thunderstorms as it would keep the region under dry
southwesterly flow between the northwest trough and four corners
high. It would also keep temperatures closer to normal with typical
or slightly enhanced afternoon southwest to west winds. -dawn

Aviation
Vfr with mostly clear to partly cloudy skies now through the
weekend. West to northwest winds will be gusty today as a late
season strong cold front drops into the great basin. Peak wind
speeds will be 20-30 kts today for area terminals. Light to moderate
turbulence will be likely with wind shear also possible. A secondary
frontal boundary Friday will shift winds north then northeast with
continued breezy conditions. Local gusts of 20-25 kts will be
possible Friday. Conditions look to remain dry through the weekend
with lighter winds. -dawn

Hydrology
Flows should peak on the walker river and in the eastern sierra
today, falling over the weekend due to cooler weather and changes in
reservoir management. The walker basin remains above bankfull, but
below flood stage. We will continue the flood advisory there with
numerous reports of low lying nuisance flooding, but no significant
impact. Elsewhere, the creeks draining the eastern sierra will
continue to run high and cold so be extra cautious around them
through the weekend. Keep in mind -- peak flows will occur
overnight in the eastern sierra so you may want to be careful
where you set up that tent or risk waking up to a surprise.

The humboldt continues it's slow rise with minor flooding occurring
and moderate flooding possible above rye patch reservoir by this
weekend or the early part of next week. It looks like the humboldt
is beginning to crest upstream between comus and golconda, but
considering how slowly this river responds, we are unlikely to see
it fall near imlay for another 1-2 weeks, with flood concerns likely
continuing into early july before things start to ramp down.

The upper reaches of basins (especially the walker basin) still have
a fairly substantial amount of snow, so we aren't out of the woods
yet when it comes to high flows, especially when temps warm again.

-dawn

Fire weather
A strong cold front given the time of year will move through
northeast ca, the sierra, and western nevada today. Widespread wind
gusts 25-35 mph are expected with humidities bottoming out in the 12-
20% range for basin areas and 18-28% for sierra valleys. This puts
the area in marginal to low-end critical conditions weather-wise;
however, live fuels remain unseasonably moist with the main concern
for fire spread being any cured-out grasses in the basin valleys
or foothills. With the unsupportive live fuels, fire warnings are
not currently being issued.

Northerly flow ensues Friday into Saturday for much cooler
temperatures and lessening winds.

The next period of some concern will be next week, especially
Tuesday through Thursday, as a fairly strong trough for the time of
year sets up shop near the pacific northwest coast. This will lead
to several breezy and dry days with little hope for rain. With live
fuel moistures dropping, we will be checking with fuels experts and
the gaccs between now and then to consider whether watches or
warnings will be needed for next week. -snyder dawn
