Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
408 AM PDT WED AUG 31 2016

.SYNOPSIS...
Expect dry weather and a slight cool down over the central
California interior for the next several days.

&&

.DISCUSSION...
A weak fetch of mainly upper level moisture has provided just
some high clouds brushing the northern half of interior central
California but skies are now clear across the area. Temperatures
are generally mild, running mostly a degree or so higher than 24
hrs ago.

Model consistency provides good confidence in the continued
development of a mid/upper level trough along the west coast
through the end of the week. Expect temperatures to continue to
run near climo for the next couple of days in a southwest to west
flow on the frontside of this developing trough. As the deepening
trough moves inland by the end of the week we will see a cooling
trend, with temperatures dropping to around 4-8 degrees below
normal during the Labor Day weekend.

After the holiday period, models begin to diverge a bit in the
details but generally weaken and lift out the trough through the
middle of next week. this will bring an upward trend in
temperatures, but without a significant building ridge of high
pressure, highs are expected to only return to around seasonal
averages.

There will be periods of moderate gusty winds over ridges and
through and below mountain passes as the trough and associated
shortwave impulses traverse the area through the weekend.
Precipitation is not expected throughout the period, as there
is no associated moisture accompanying the passing trough.


&&

.AVIATION...
Smoke from wildfires will reduce visibilities to MVFR in some areas.
Otherwise, VFR conditions will prevail over the central CA interior
during the next 24 hours.

&&

.AIR QUALITY ISSUES...
On Wednesday August 31 2016... Unhealthy for sensitive groups in
Fresno... Kern and Tulare Counties and Sequoia National Park and
Forest.
