Synopsis
Temperature will cool over the weekend with below average
temperatures by Sunday. Warming slowly through next week to a
little above average with triple digits in the valley by mid-week.

No precipitation expected over interior norcal through the
extended period.

Discussion
Relative to last night, most locations have seen a notable
decrease in overnight temperatures, generally in the 5 to 10
degree range. The erosion of the four corners ridge has allowed
mid-level heights to lower over northern california. Further
amplification in the northern stream flow this weekend will allow
temperatures to move below average by Sunday. Valley highs will
range from the mid upper 80s sacramento southward to the low 90s
over the northern sacramento valley. Such readings should continue
into Monday, thus offering some relief after multiple days in the
triple digits.

The shift in the pattern will also support a significant uptick in
the delta breeze. Through Monday morning, sustained wind speeds
around the delta region should be in the 25 to 35 mph accompanied
by higher gusts. The resultant southerly flow across the valley
will offer the noted relief from the earlier week hot
temperatures. Given the enhanced marine influence to the air mass,
there will likely be an increase in low clouds extending out of
the delta the next couple of nights mornings. This is supported by
nam model soundings as well as the href probabilities.

Looking beyond Monday, a strengthening trough off the coast will
build heights across the state by Tuesday. This ultimately brings
temperatures to near average after a multi-day cool down. ~bro

Extended discussion (Wednesday through Saturday)
Ensembles show high pressure peaking over the area around mid-
week before weakening slightly as a weak trough develops along the
west coast later next week. Temperatures will be around 5-10
degrees above average for late-august mid-week, cooling to
slightly above average toward the end of the week. &&

Aviation
Vfr conditions next 24 hours. Local southwesterly wind gusts 25-35
kts vicinity carquinez strait and west delta. Areas southerly wind
gusts 15-25 kts sacramento valley 22z-06z Sunday. Lighter winds
elsewhere.

Sto watches warnings advisories
None.
