Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
1250 PM PST Sun Nov 19 2017

.SYNOPSIS...
A weak disturbance will mainly bring high clouds to central
California tonight and Monday. Otherwise, a ridge of high pressure
builds over the region through mid week. This will result in dry
conditions and warming temperatures. In fact, temperatures will be
above normal most of the upcoming week.

.DISCUSSION...
The first focus in the short term weather will be the high clouds
streaming over California from the Pacific Ocean. Trajectories
take this mid/upper level moisture over California tonight into
early Monday. Thinking is at least broken high clouds until Monday
afternoon. This cloud cover should limit fog formation across the
San Joaquin Valley later tonight. Cannot rule out some patchy fog,
so will include that in the forecast. After tonight, it becomes
even harder for persistent fog formation with rising overnight
temperatures expected across the valley.

Otherwise, a mid to upper level ridge dominates southern and
central California through the Thanksgiving holiday. Models are in
good agreement that this ridge will drive any storm systems to the
north of the forecast area. Heights build through mid/late week to
keep even most of the central and southern Sierra Nevada Mountains
dry. One more thing with this pattern...any cold air or fronts
will remain well north of the area into the extended forecast
period.

Therefore, going dry with temperatures above normal from Tuesday
through Friday, possibly into Saturday of the holiday weekend.
It looks like a slight change in store later next weekend, but
plenty of time to determine. In the meantime, forecast confidence
for central California will remain high.

.AVIATION...

Joaquin Valley. However, high cloud cover should keep it MVFR

wind will generally be light along all routes.
