.DISCUSSION...

As the recent low pressure system migrates across the
California/Nevada border this afternoon, showers and snow chances
will persist. Snow is possible above 8000 feet, with some light
accumulations (0.5" up to 3" for the highest elevations) found along
the Sierra from the Tahoe Basin south into Mono County. Snow showers
will taper this evening, lifting into the Great Basin overnight.

The exit of the low will allow for some drier air to filter in
behind the system. The temperatures will remain below average for
the weekend and early week, with cool northwesterly breezes
remaining through Saturday. Winds will remain largely northerly
into Sunday, ensuring we keep the colder air in place. Overnight
lows will remain below freezing for our neighbors in Sierra valleys,
while leeside valleys hang onto lows in the upper 30s to low 40s.

By midweek, the low is trying to escape the western region, which
allows for some warming as a minor ridging pattern attempts to take
hold. Beyond midweek, ensemble guidance indicates a retrograding
trough may arrive for Thursday, bringing around more chances for
showers. As can be the case with guidance this far out, details will
become clearer as we go forward in time. The main takeaway is that
we are in a fall pattern, which can provide a variety of solutions
in the ensembles. HRICH

.AVIATION...

* Scattered hit/miss rain showers with MVFR to local IFR for western
  NV terminals are likely after 18z through 03-06z. Snow is possible
  above 8,000`. For KMMH, this will lead to MVFR to IFR conditions
  as well as mountain obscurations.

* Winds are overall light for all terminals today, with sustained
  winds around 10 kts and gusts to 20 kts. Some minor turbulence
  and LLWS is expected through this evening for the eastern Sierra
  terminals. -McKellar/HRICH
