Area Forecast Discussion
National Weather Service Sacramento CA
935 AM PDT THU JUN 23 2016


.SYNOPSIS...
Cooler temperatures today and Friday with highs near normal.
Warming again over the weekend remaining well above normal through
the middle of next week. Locally breezy northerly wind possible
later Friday into Saturday with elevated fire weather concerns.

&&

.DISCUSSION...
553 mb upper low off the B.C. coast is spreading some precip over
the PacNW this morning. Associated upper troughing is moving over
NorCal resulting in increased onshore flow and synoptic cooling.
Temperatures this morning running upwards of about 7 degrees
cooler and expect this to be reflected in max temperatures later
today. Highs in the Central Valley forecast in the lower 90s this
afternoon which is normal for this time of year. Locally gusty
southwesterly wind possible over higher terrain this afternoon.

Strong delta breeze and gusty wind over higher terrain expected
overnight as trough axis moves through. Associated precip with
frontal system is modeled to remain well north of the forecast
area. Little change in heights and thicknesses Friday as surface
high pressure builds through Oregon. As a result, max temps
tomorrow expected only a few degrees above today. Locally breezy
northerly wind possible tomorrow afternoon into Saturday, mainly
over northern and western portions of the Central Valley.

Upper ridging forecast to build over Interior NorCal over the
weekend resulting in a return of triple digit heat to portions of
the Central Valley.

.EXTENDED DISCUSSION (Monday THROUGH Thursday)

High pressure will dominate our weather pattern with above normal
temperatures. Daytime highs will range 5-14 degrees above normal
Monday thru midweek. Expect dry conditions with temperatures in
the upper 90s to 105 across the Valley, and 70s-90s over
foothills and mountains.  JBB
