320 PM PDT WED AUG 31 2016

Dry weather with below average temperatures this week. Locally
breezy at times...mainly in the Delta and over ridgetops.


Temperatures at 3 pm were within a few degrees of yesterday (+/- 4
degrees) as valley highs were in the mid 80s to low 90s. Daytime
highs are expected to range 1-7 degrees below average between today
through Saturday with Friday being the coolest day in the short
term forecast. The upper level trough over the West Coast is
ushering in cooler air aloft while also helping cool, marine air
move into the central valley. Despite having this trough linger in
our area into the weekend, no precipitation is expected...just
slightly cooler trend in temperatures and locally breezy
conditions through the Delta region and over mountain ridgetops.

Temperatures will gradually start to warm on Saturday as the
trough begins to weaken slightly and drift eastward. Valley
temperatures should remain in the 80s to low 90s the rest of the
week, with 60s-70s for the foothills and mountains.


Longwave trough slowly begins to shift east for the start of next 
week. Below normal temperatures will continue on Sunday before a
slight warming trend on Monday/Tuesday. Even then, temperatures
will only be near to a few degrees above normal. Precipitation is
expected to remain north of the state. Northerly flow will return
to much of the area, but at this point, looks fairly light as
ridging struggles to take hold. CEO



VFR conditions across TAF sites next 24 hours. Onshore flow with
gusty ridge winds, especially over Sierra. Gusts 25 to 30 knots
into Delta.
