5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Synopsis
High pressure will bring much above average temperatures through the
weekend with some cooling by early next week. Isolated thunderstorms
are possible through Saturday near the sierra, spreading into parts
of western nevada Sunday. Dry and breezy conditions are expected
early next week. Flooding will continue for the creeks in mono
county and portions of the walker river.

Short term
Latest models remain relatively consistent with previous runs, so
no major changes were made to the forecast. Largest changes
concerned trimming thunderstorm chances for Sunday and adding a
fire weather watch for Monday afternoon and evening.

Ridging will remain the predominant weather feature through the
weekend keeping conditions hot and dry. Forecast 850mb and 700mb
temperatures suggest triple digit highs for western nevada and
upper 80s to around 90 in sierra valleys for the weekend. Winds
will also remain fairly stagnant under the ridge axis through
Sunday.

Expect isolated thunderstorms mainly over the sierra crest in
mono alpine counties for this evening and late Saturday afternoon.

Chances do become more expansive Sunday, but the overall coverage
has been reduced a bit; mainly to trim thunderstorms out of the
tahoe basin. Models are showing a more progressive passage of a
short wave trough early Sunday morning. Since upper level forcing
is temporally out of phase with low level instability and surface
convergence, chances of afternoon thunderstorms will be lower.

However, there will be a tightening of the thermal gradient, about
22 degrees from the sierra to the nevada interior, that will
allow for a more pronounced afternoon zephyr. The sierra front may
see some isolated convection as a result of increased afternoon
convergence over the valley, but the best chances remain over mono
county, northern lassen county, and along the virginia, pine nut,
and pah rah ranges.

Long term Monday through Friday...

upper level troughing is still on track to shift inland increasing
the surface pressure gradient across the region. As a result,
winds will become breezy Monday afternoon. These increasing winds
coupled with very low rh will likely result in critical fire
weather conditions for western nevada; see the fire weather
discussion below.

Upper troughing sags southeastward Tuesday and Wednesday keeping
winds a little breezy while temperatures begin to cool somewhat.

Highs for the rest of the week will drop into the low mid 90s for
western nevada and upper 70s for sierra valleys through the week.

Aviation
Towering cumulus are currently building along the sierra crest in
alpine and mono counties. Isolated thunderstorms are possible for
the sierra south of alpine county today and Saturday. This will
mainly affect flights arriving and departing from kmmh.

Otherwise, expectVFR conditions to prevail with light northeast to
east flow. Thunderstorm chances increase slightly and spread north
to the oregon border Sunday. Also, temperatures will increase
above 100 degrees for western nevada terminals and to around 90
for sierra terminals.

Breezy to gusty winds will be possible early next week with a
slight cool-down for the rest of the week. Johnston boyd

Fire weather
Afternoon temperatures will soar into the mid 90s to low 100s once
again this weekend. Based on what was observed this morning and with
little change expected, recoveries should be poor to moderate for at
least the next couple nights for much of the western great basin and
sierra front. Exceptions will be the colder valleys of northeast
california, as well as the sierra valleys, where moderate to good
recoveries are still expected. A few storms are possible today and
again Saturday near the sierra; however, the coverage of storms
should remain low.

Sunday, an upper disturbance will move over northern california in
the morning. Due to the weakness of the impulse, the wave is not
expected to initiate any elevated thunderstorms. The main possible
impact from the disturbance will be Sunday afternoon as a zephyr is
induced as thermal gradients increase between the sacramento valley
and west-central nv. This is expected to encourage the development
of mainly isolated thunderstorms along the leading edge of the
zephyr, as well as north of susanville and gerlach in the typical
convergence zone there. With inverted-v profiles and storm motions
in the 10-15 mph range (based on cloud-level flow from simulations,
there is definitely the threat for dry lightning strikes. However,
with the wave timing in the morning, the coverage should remain
isolated. Still, winds gusts over 50 mph could affect a few areas
for an hour or so near any storms.

Turning to Monday, the upper ridge bringing the hot temperatures
will break down. This will bring a cooling trend lasting into mid-
week, with stabilizing southwest flow aloft ending the threat for
thunderstorms. Unfortunately, it will also bring increasing winds
for Monday as thermal gradients are maximized across the region.

Monday afternoon and evening, sustained winds could reach around 20
mph with gusts up to 35 mph. This could threaten to bring renewed
vigor to any fires started by Sunday's convection or to any new
fires. Also, some simulations show a dry slot moving in Monday night
for a possible continuation of poor recoveries on midslopes. With
all this in mind, a fire weather watch is out for fire zones 450 and
453. Other areas will have winds and low humidities, but they have
not yet been cleared for red flags by the gacc. Snyder

Hydrology
Rapid snowmelt from the remaining deep high elevation snowpack will
be driven by hot days and warm nights. expect continued very high
flows at least through Sunday night on creeks and streams draining
high elevation terrain near the sierra crest, as well as creeks
draining the eastern and northeastern flanks of mt. Rose. This
includes the forks of the walker river, other creeks and streams in
mono county, galena creek, and neighboring creeks in the mt. Rose
area.

Peak nighttime flows through Sunday night are likely to be similar
to observed peaks over the last three nights. A combination of
slightly cooler temperatures and depleting snow covered
contributing area should lead to gradually decreasing flows
starting early next week.

Preliminary measurements of snowmelt flows on the west walker above
and below topaz reservoir have exceeded the previous snowmelt peak
flow of 1995 and that water is slowly moving into and through the
mason valley.  fortunately this year at this time, the east
walker is contributing significantly less water than it was during
the peak of 1995. The combination should lead to flows and
impacts in the mason valley and downstream similar to or slightly
less than from the peak flows of mid-july 1995.
