Area forecast discussion 
National Weather Service San Joaquin Valley - Hanford California
208 PM PDT Sat Jul 23 2016

Synopsis...
mostly clear skies with above average temperatures are expected over
the next several days as high pressure moves in from the east.

&&

Discussion...top of the ridge has been flattened off over the
area as a trough of low pressure moves across the Pacific
northwest. The driest of air is noted on water vapor imagery just
to the north of central California. Meanwhile the nose of the
ridge is seen pushing back to the west over northern Baja
California and this feature will continue to remain the dominant
weather feature over Southern California for the next few days.

Forecast models bring another trough of low pressure across
northern California Sunday and yet another but weaker short wave
trough through the area on Monday. With the generally westerly
flow aloft continuing through this time frame, dry air will
continue to move in the region with skies remaining clear. By
Tuesday and Wednesday models build the ridge northward and
westward into the area with the ridge holding strong into Friday.
The flow aloft will become lighter beginning Tuesday and will turn
to a more southerly directing as the week progresses. At this
time, models are keeping the main monsoonal moisture to the south
and east of the forecast area however with the projection of the
ridge persisting well into next weekend, some moisture just may
reach the Kern County mountains and desert as will as the southern
Sierra.

Temperatures will hold stable Sunday and Monday as the low
pressure troughs move to the north however by mid week the
position of the ridge will allow for additional heating.
