Synopsis
Above average temperatures Monday will ease down closer to average
for the rest of the week as low pressure slides into northern
california and far northwest nevada. Typical afternoon and evening
breezes may bring periods of fire concern for the next few days.

A few thunderstorms will be possible north of susanville and
gerlach on Tuesday.

Short term
Added isolated showers and thunderstorms to far northeast ca and
northwestern nv, otherwise little change to the forecast through
Wednesday.

Low pressure near the oregon coast will slide south into northern
california and extreme northwest nevada Monday night and Tuesday.

The low is fairly weak; however, it will serve to induce typical
afternoon and evening breezes (gusts 20-25 mph, locally to 30 mph
far western nv) for northeast california and western nevada for
the next few days. Also, it will help bring down high temperatures
closer to average by Tuesday and Wednesday, with continued cool
to chilly nights for most spots.

One other feature with the upper low will be low chances (isolated
coverage) for showers and afternoon thunderstorms across far
northeast ca and northwest nevada (north of gerlach) on Tuesday.

-snyder

Long term Thursday through next weekend...

very few changes were made to the forecast since the last update. A
trough will exit the pacific northwest Wednesday allowing heights to
build over the great basin for a couple days before another trough
approaches the pacific northwest next weekend. This pattern will
continue to favor dry conditions, above normal temperatures, and
typical afternoon breezes for areas of western nevada and eastern
california.

High temperatures will remain in the low 90s for the lower valleys
of western nevada, which translates to highs in the upper 70s lower
80s for sierra valley locations. Overnight lows will be in the upper
50s low 60s for lower elevations, with low 40s expected for sierra
valleys.

No showers or thunderstorms are expected through Saturday due to the
persistent southwesterly flow over the sierra and western nevada.

Some relief from the heat may be in sight beyond the forecast
period as operational guidance and ensembles are hinting at a
more robust shortwave trough digging south into northern
california nevada. However, the location of this trough will
undoubtedly vary within future model runs. -johnston

Aviation
With continual southwesterly flow expected through Tuesday, smoke
will likely clear across the tahoe basin and much of western
nevada. However, slant-wise and flight level visibility will
likely be reduced for areas north of susanville and gerlach, in
addition to areas immediately downwind of the lions and donnell
fires in alpine mono mineral counties. Expect dry conditions with
enhanced wind gusts up to 25 kts this afternoon and evening, with
gusts to 25-30 kts Monday Tuesday. -johnston

Fire weather
Winds are still the main focus when it comes to potential critical
conditions the next couple of days. A trough dropping slowly south
will produce brief periods of localized critical conditions over
northern parts of zones 271 and 278 late this afternoon and early
this evening along with parts of 270 and 458. There is also the
chance for wind prone areas to briefly gust over 30 mph in zone 450.

The gusty winds should not be widespread enough nor last long enough
to warrant any red flags for today.

Another round of locally gusty winds is possible for Monday...

especially along the sierra front where wind prone areas may exceed
30 mph. But... Again... This does not appear to be a situation where
the winds will be widespread enough nor last long enough to warrant
a red flag warning. The fire community should be aware that brief
gusty winds in the very dry conditions could help spread any new
fire starts even if the winds are not in the critical range.

Rh recoveries will be poor to moderate tonight and again Monday
night for all but the cooler valleys. Winds should continue overnight
at the ridge tops and dry air ahead of the trough should push over
the ridges and mid-slopes.

The last concern is the potential for thunderstorms near the oregon
border. The trough may have enough moisture and instability for
isolated storms near the oregon border Tuesday. That would mean
dry lightning outside any rain cores along with gusty outflow
winds. Xx

Rev watches warnings advisories
Nv... None.

Ca... None.
