Area forecast discussion
National Weather Service San Joaquin Valley - Hanford California
154 am PST Tue Feb 28 2017

Synopsis...
high pressure is forecast to build on over the region with drying
and a temperatures trending towards normal through Monday. A weak
front will move to our north on Sunday with a slight chance of
showers north of Fresno County.

&&

Discussion...
deep upper trough is moving through the area attm. Northwest flow aloft
is causing upslope clouds and light showers along the north and
west facing slopes of the tehachapis and the Sierra. Drier air
will move in behind a second shortwave forecast to move through
this am. No sjv fog is is expected this am due to mixing and
drying conditions.

Generally northwest flow through Sunday with seasonal temperatures and
dry conditions expected. We could see some patchy frost in the
sjv tonight in some of the rural areas. Temperatures will warm to
near normal and remain that way for the next several days.

The GFS and ecm are not in great agreement concerning a cold front
that is forecast to move north of the region on Sunday. It is not
expected to make very much progress to the south as dynamics are
weakening as it moves onshore. The front quickly falls apart and
it will be marginal if we even see any precip north of Fresno
County on Sunday or Monday. We have slight chances, which is
pretty close to climo for this time of year. A quiet break for the
central CA interior for the next several days with seasonal temps
and dry conditions.
