.DISCUSSION...

High pressure continues to build through midweek, bringing
afternoon highs up past normal. Wednesday continues to look to be
the warmest day of the week with valley highs in the upper 70s and
Sierra highs pushing the low 70s. Chilly overnight lows are
expected to subside through midweek before another weather system
brings overnight lows back below freezing along the Sierra this
weekend.

A low pressure centered along the coast of British Columbia drops
down this week, and will stall along the coast of the PacNW
before pivoting inland Friday. The timing of this pivot inland is
a bit up in the air as models attempt to resolve the relatively
"small" feature. What we do know, though, is that afternoon wind
gusts will continue to increase each afternoon Wednesday through
Friday, peaking Friday afternoon. Gusts Friday are expected to
exceed 30-35 mph across much of the area. We are also confident in
a significant cooldown this weekend, with 5-15 degree temperature
drops across the area from Friday into Saturday; highs will be in
the 60s for valley locations and mid 50s for Sierra communities.

The aforementioned uncertainty will most prominently be seen in
the timing of the system as well as the amounts associated. As of
now, precipitation chances are highest (40-60%) Friday evening for
NE CA and north of the Tahoe Basin. Amounts look to be light
(0.1-0.3") and possible snowfall totals have trended downward
with this system. However, that doesn`t mean some flurries aren`t
possible; snow levels will range from 7-8 kft during the bulk of
this system.
