AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
915 PM PDT Tue Aug 26 2014

.Synopsis...
High pressure will bring a slight warming trend the next couple
of days, followed by a weak trough by this weekend bringing
increasing high clouds and cooler temperatures.

&&

.Short Term Discussion (Tonight through Friday)...
High pressure building over the interior tonight is helping to
keep temperatures a little warmer this evening. Temperatures are
generally running about 5 degrees warmer at this time compared to
last night. There is moderate flow through the delta this evening.
Temperatures will cool into the upper 50s to mid 60s in the
valley overnight to mainly 40s and 50s for the mountain
valleys.

The high pressure will strengthen a little for Wednesday and
temperatures will warm a couple of degrees over todays highs. A
weak wave will pass well north of California on Thursday and
flatten the ridge a little but little change in temperatures is
expected when compared to Wednesday`s highs.

On Friday a deeper low will develop over the west coast and some
high clouds from hurricane Marie may spread over parts of the
interior. The trough`s position is currently trying to keep the
high clouds from spreading over the northern forecast area.

&&

.Extended Discussion (Saturday through Tuesday)

An upper level trough over the Western U.S. on Saturday and Sunday
bringing some clouds and onshore flow along with cooler
temperatures. High temperatures are generally expected to be in
the mid 80s to low 90s in the valley and 60s and 70s in the
mountains this weekend. On Monday and Tuesday, Northern California
is between the trough to the east and ridge of High pressure to
the west over the Eastern Pacific. This will bring a little warmer
temperatures along with dry Northwest flow aloft. Max temperatures
