Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
103 PM PDT SUN AUG 28 2016

.SYNOPSIS...
Dry weather and near normal temperatures will prevail over the
central California for the next several days.

&&

.DISCUSSION...Satellite loops show mainly clear skies over the
region, although a few cumulus clouds have developed over the
Sierra Nevada crest. The marine layer along the coast has been
gradually decreasing in depth as we progress through today,
although it remains around 2000 feet per latest Ft Ord profiler
data. Also, wildfire smoke continues to linger over parts of the
San Joaquin Valley and adjacent foothills/mountains, and we
expect this to continue for the next couple of days, as an upper-
level ridge continues to build. High temperatures will likely peak
around a couple of degrees higher than yesterday, as temperatures
have generally been trending around 1 to 3 degrees warmer than
this time yesterday.

Expect slight warming for Monday and Tuesday as high pressure
ridging continues over the region. Dry air will remain over much
of California, so expect little changes in weather. By Tuesday
night, the ridge is progged to shift eastward with the axis
centered over the Rocky Mountain and Desert Southwest states.
Also, a shortwave trough of low pressure will move over northern
California by Tuesday afternoon and will open the door for a
longwave pattern to set up for the latter half of this week. By
Thursday and Friday, winds will likely increase with breezy
conditions, with locally gusty conditions at times, in the usual
prone areas of eastern Kern County as well as the west side of the
San Joaquin Valley.

Models remain in decent agreement in keeping a longwave trough
pattern along the West Coast for the upcoming Labor Day weekend.
Confidence continues to increase a little with each model run;
however, timing differences remain. A dry weather pattern will
likely continue for this period with temperatures remaining near
to perhaps a few degrees below average. For example, highs could
struggle to reach 90 degrees in some locations of the San Joaquin
Valley, such as in Merced County.

&&

.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.
