.SYNOPSIS...

the upcoming week. Temperatures will remain above seasonal
averages.

.DISCUSSION...

We have ushered in the first day of October with clear skies, light
winds, and seasonal temperatures throughout the eastern Sierra and
western Nevada. You couldn`t wish for a more beautiful fall
afternoon! A closed low currently over Idaho will continue to slowly
find its way into MT on Sunday as ridging starts to build back
into the western U.S. Model ensembles are in solid agreement that
this ridging pattern will remain in control for the entire
upcoming week.

High and low temperatures will be above seasonal averages through
the end of the 7 day forecast period next Saturday, with the warmest
days occurring Wednesday through Friday. For regional high
temperatures, we`ll be looking at low to mid 80s for western NV
and northeast CA. Low to mid 70s will be common for most eastern
Sierra locations, with mid 50s to near 60 degrees for the higher
elevations. Mornings will still be on the chilly side for our
Sierra valleys, with low to mid 30s. It will basically be an
entire week of perfect outdoor fall weather!
