...Extensive Period of Stormy Weather Anticipated to Start 2021...

A notable change to a more active weather pattern is forecast for
the Sierra and western Nevada with multiple periods of strong winds,
heavy mountain snow, along with valley rain and snow. This will
likely cause significant travel impacts in the Sierra next week.
Chances for valley snow (including down here in Reno/Carson) will
be increasing by midweek.

* Active storm track for next week: A much wetter and windier
pattern is expected to begin late in the weekend and last
through much of next week as a series of Pacific storms with
adequate moisture affects the Sierra and western Nevada. Showery
precipitation is expected to begin Saturday through the weekend,
with the best chances for strong storms with significant
precipitation and wind looking to be Sunday night into Monday
and again Wednesday into Thursday. The latter storm is trending
colder, which means increased chances for snow in western
Nevada valleys.

* Abundance of impacts next week: Periods of heavy snow in the
Sierra with significant travel disruptions for passes along with
avalanche concerns. Rain or snow (or both) for mountain valleys
and western Nevada valleys. Strong winds are possible, which may
result in impacts for high profile vehicles and aviation, and
possible tree and fence damage near wind prone areas. Keep a
close eye on the forecast, be sure to allow extra time, and
check road conditions with NDOT and Caltrans before you depart.
