.DISCUSSION...

An upper level shortwave over the Pacific NW will help keep
afternoon high temperatures similar both today and tomorrow (low
80s valleys, low to mid 70s Sierra). It will also bring increased
breezes Friday afternoon, with gusts 30-35 mph, mainly from the
Sierra and eastward.

High pressure only strengthens this weekend, helping us warm up
and dry out. Afternoon highs will shoot into the upper 80s/low 90s
by late this weekend for valleys, with upper 70s/low 80s for
Sierra communities. The record highs for Reno Sunday through
Tuesday are 90F, 89F, and 91F, respectively. Current chances to
exceed 90F Sunday through Tuesday are 22%, 74%, and 60%,
respectively. Monday looks to be the best chance at hitting, or
surpassing, records as of now.

The aforementioned high pressure peaks in intensity Monday over
the Great Basin before shifting more to the Four Corners region by
Wednesday. This may bring up some moisture from Baja California,
which increases chances for showers and thunderstorms Wednesday
and onward.
