Area Forecast Discussion
National Weather Service Sacramento CA
958 AM PDT TUE AUG 23 2016


.SYNOPSIS...
A subtle warm up expected Wednesday and Thursday, but still
around seasonal averages. Then weak troughing late in the week
will cool temperatures to below normal levels.

&&

.UPDATED DISCUSSION...
Skies are clear across interior NorCal early this morning. The
main trough is into the Great Basin. So thunderstorm across the
area should greatly diminish...limited to the southern Sierra
southward of Yosemite. Persistent weak upper trough will continue
pleasant pattern across the region through the remainder of the
week.         JClapp

.EXTENDED DISCUSSION (Saturday THROUGH Tuesday)
Upper low/trough off the West Coast over the weekend is progged
to progress across NorCal Monday or Tuesday. Models differ on when
it moves through with GFS about 24 hours faster than the ECMWF. In
either case, available moisture is limited and main impact appears
to be increased onshore flow with some synoptic cooling. Below
normal temperatures are expected through the extended forecast
period with 80s to lower 90s in the Central Valley with 60s to 80s
for the mountains and foothills.


&&

.AVIATION...
Northwest flow aloft with trough axis over the Great Basin.
Stratus retreating this morning with marine layer at 1700 ft at
Ft. Ord and Bodega Bay profilers. MVFR/IFR stratus likely to
return to Cordelia tonight and possibly creeping in south of
Travis AFB Wednesday morning. Local southwest SFC wind gusts
30-35 kts in Delta again 22z-13z.         JClapp


&&

.STO Watches/Warnings/Advisories...
None.
