.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.

&&

.SHORT TERM DISCUSSION (Tonight through Friday)...
Skies are clear across interior NorCal today. The main trough is
into the Great Basin so showers/thunderstorms remain southeast of
Yosemite. Persistent weak upper trough will continue pleasant
pattern across the region through the remainder of the week.

.EXTENDED DISCUSSION (Saturday THROUGH Tuesday)

ECMWF progs an upper low/trough off the West Coast to move across
NorCal Monday or Tuesday while the GFS keeps the trough over
Oregon with ridging/anticyclonic flow over NorCal. Either way,
available moisture is limited and main impact appears to be some
increased onshore flow. Temperatures are the question mark with
these two pattern differences. We split the difference and kept
temperatures below to near normal for the extended. JClapp

.AVIATION...
NW flow aloft with trough axis over the Great Basin. Marine layer
slight lowered today to about 1500 ft at Ft. Ord, but stayed at
1700 ft at Bodega Bay profiler. MVFR/IFR stratus likely to return
to Cordelia tonight with only limited possibly of stratus creeping
into Sac Valley Wednesday morning. Local SW SFC wind gusts 30-35
kts in Delta again 22z-13z.      JClapp
