Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
153 PM PDT Sat Mar 25 2017

.SYNOPSIS...Unsettled weather will continue through the weekend
before a warming and drying trend takes hold of central California
next week.

&&

.DISCUSSION...Cooler, unsettled weather will continue for the
remainder of this weekend. Latest satellite images continue to
show low clouds over much of central California. Although there
are a few showers developing over the Sierra Nevada around
Yosemite and just west of western Kern County, expect this
activity to diminish by this evening.

The next low pressure system is progged to arrive by Sunday
afternoon; we have at least a slight chance for showers for much
of the San Joaquin Valley north of Kern County during the
afternoon. The system will then progress southward, including over
Kern County, during the overnight hours from Sunday night into
Monday morning. The trough is expected to move eastward by Monday
evening, although some clouds could persist along west/north-
facing slopes in the southern Sierra Nevada and Tehachapi
Mountains. Gusty winds are likely behind the low pressure system
during the afternoon and into the early evening on Monday in the
Kern County mountains/desert, with gusts to around 50 mph expected
and possibly locally stronger. In addition, some breezy
conditions are likely along the west side of the San Joaquin
Valley, where gusts could reach around 40 mph in some locales.
Temperatures will likely remain below seasonal averages through at
least Tuesday, or until high pressure returns to the West Coast.

Expect mainly dry conditions, at least for Tuesday and Wednesday.
Another low pressure system may clip Yosemite on Thursday,
although is forecast to move mainly as an inside-slider. At this
time, any significant precipitation is forecast to move mainly
along the east side of the Sierra Nevada. Based on latest model
data and trends, am not very confident at this time, but have a
slight chance for precip over the Sierra mainly from Yosemite to
Kings Canyon NP. Otherwise, expect a dry end to next week over
much of central California, while temperatures trend back towards
seasonal averages.

&&

.AVIATION...
In the San Joaquin Valley, areas of MVFR in low clouds thru 18Z
Sunday.

In the Southern Sierra Nevada and adjacent foothills low clouds
banking along the lower elevations with local mountain obscurations.

In the Kern County Mountains, low clouds upsloping along the lower

central CA interior for the next 24 hrs.
