Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
257 AM PST Wed Mar 1 2017

.SYNOPSIS...
Dry conditions and a warming trend will occur through the end of
the week, then a chance for precipitation returns Saturday night
into Sunday.

&&

.DISCUSSION...
Clear skies and light winds prevail under a dry northwest flow
aloft. A chilly air mass remains with 24 hour temperature trends
showing little change across the San Joaquin Valley. Morning lows
will again be in the 30s this morning and some patchy frost is
likely is rural areas.

March has come in like a lamb with quiet weather in store through
the end of the week. Weak high pressure will build across from the
Pacific for a warming trend under sunny skies. Highs by Friday are
forecast to nudge slightly above climo with parts of the SJ Valley
possibly reaching 70 degrees.

The weekend looks to start dry with little change in temperatures,
but a return to some wet weather is possible for the latter half
of the weekend. An upper trough dropping down off the Pacific NW
coast will bring precipitation to northern California and models
are now trending a little farther south with this system. Precip
may arrive Saturday night with the best chances on Sunday from
Fresno County north. Confidence is just medium at this point as
models have been struggling with track and timing. POPs have been
nudged upwards to high chance category around Yosemite and low
chance in the central SJV, with just slight chances painted south
of Fresno County. The trough shifts inland Monday with some light
showers still possible. The GFS indicates dry weather thereafter
while the ECMWF suggests another chance for precip by midweek.

Winds will remain light through Saturday then are expected to
increase on Sunday with breezy to gusty conditions, especially
through and below mountain passes.
