Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
144 PM PDT FRI OCT 21 2016

Above average temperatures will prevail through Saturday. A storm
system will approach northern California this weekend and bring a
cooling trend beginning Sunday. Another storm system will bring a
better chance for rain and higher elevation snow in central
California by late next week.&&

.DISCUSSION...As expected, temperatures are up 3-5 degrees across
much of the forecast area this afternoon as the ridge of high
pressure to the south moves to the east and brings the warmest air
into the Central California Interior. Over the West satellite
images show the ridge covering much of the area with the storm
track well to the north across western Canada, near the Queen
Charlotte Islands.

Over the weekend, models continue to shift the ridge to the east
and move a trough of low pressure towards the west coast. Given
this, temperatures will just slowly cool as heights lower. As for
any precipitation threat, it looks like the early upcoming week
will see just a very small threat of rain as the GFS and ECMWF
models bring a little tropical moisture into far southern
California but keep Kern County dry. Meanwhile, to the north a
Pacific frontal system is projected to move into the northern part
of the state but again not affect the Central Interior.

All eyes are now looking to later next week for a chance of a
possibly wet weather system to affect the region. For the past
couple of days, the GFS model has been projecting a low pressure
system with lots of moisture approaching the coast on Thursday and
moving ashore by Friday. Today, the ECMWF model has the same
solution thus confidence is increasing that this scenario may
actually pan out. Pops have been increased into the slight chance
to chance categories over the forecast area.


VFR conditions will prevail at all terminals through the next 24
