Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
128 PM PDT FRI AUG 26 2016

.SYNOPSIS...
Dry weather will prevail over the central California for the next
several days. Temperatures will remain seasonable through Saturday
then warm to slightly above normal Sunday and Monday. A cooling
trend is likely during the mid to later part of next week.

&&

.DISCUSSION...Compared to this time yesterday, temperatures have
trended significantly cooler, by around 10 to 15 degrees, in the
vicinity of Pacheco Pass and Los Banos. This cooling is courtesy
of a deepened marine layer that has spilled into the west side of
the San Joaquin Valley, including through Pacheco Pass, where
winds have been gusting to around 30-35 mph since this morning.
Elsewhere, there has been little change in temperatures. Also,
skies have been generally cloud-free except for some cumulus
buildups over the crest of the southern Sierra Nevada. Some
isolated showers and thunderstorms remain a possibility over the
crest of the Sierra, as we get further into this afternoon due to
a trough digging southward into northern California, although this
system contains little moisture.

High pressure will return for the weekend and into early next
week, so temperatures are expected to warm a little each day
through at least Monday. Generally light winds will prevail over
central California, and wildfire smoke will likely linger over
much of the area through Saturday and possibly longer. Other than
over the Kern County desert, we do not anticipate widespread
triple digit high temperatures for this weekend through Tuesday.
Temperatures will range from near to slightly above average this
weekend and into Tuesday. Dry weather will continue to prevail
over the region, as has been the case for much of this summer.

While dry weather will continue beyond the next several days, a
cooling trend is anticipated for the latter half of next week.
Below average temperatures are possible by the end of next week
as another stronger trough of low pressure builds over the West
Coast. High temperatures may even struggle to reach 90 degrees in
many San Joaquin Valley locations by next Friday. Also, breezy
conditions could impact the passes along the west side of the San
Joaquin Valley, as well as in the favored areas in eastern Kern
County. This pattern will likely continue into at least the first
half of the upcoming Labor Day weekend. Models are in decent
agreement regarding the setup of this trough pattern but continue
to display their differences in terms of timing.

&&

.AVIATION...
Scattered thunderstorms are possible over the High Sierra between
22Z today and 04Z Saturday. Smoke from wildfires will reduce
visibilities to MVFR in some areas. Otherwise, VFR conditions will
prevail over the central California interior during the next 24
hours.
