Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
143 PM PDT SAT AUG 27 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...
The marine layer deepened last night in response to a weak
shortwave trough moving through the region. This allowed the
cooler marine air to spill into the San Joaquin Valley overnight
resulting in temperatures running down 1-4 degrees across the San
Joaquin Valley so far this afternoon compared to yesterday.

The weak trough has moved east and high pressure is building into
California today and the marine layer will lower a bit. This will
allow temperatures across the central California interior to warm
a few degrees Sunday and Monday. By Monday night and Tuesday, a
low pressure system develops off the west coast of Canada with
the trough extending south along the coast of northern California.
A weak shortwave rotates through the trough and moves across
northern California Tuesday, flattening the ridge. The trough
remains along the west coast through the end of the week. This
will allow temperatures to cool several degrees across the region,
dropping slightly below normal for late August. For the San
Joaquin Valley, highs will likely range from the upper 80s to mid
90s by mid week.

Breezy conditions in the San Joaquin Valley and gusty conditions
in the Kern County desert areas will be likely with the troughs`
arrival. At this time it appears that this system will not bring
any moisture to central California, so the forecast remains dry.

.AVIATION...
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.
