Area Forecast Discussion
National Weather Service Sacramento CA
317 AM PDT SAT JUL 30 2016

A cooling trend to begin today as the dominating high pressure
pattern weakens. Near normal temperatures are expected by Sunday
with dry weather through the extended.


.SHORT TERM DISCUSSION (Today through Tuesday)...
A subtle retrograde of the Desert Southwest high pressure will
cool temperatures a bit today as weak troughing develops into
extreme northern California. Further synoptic cooling is expected
Sunday bringing temperatures to near normal. Additionally, the
weak troughing overhead will be conducive to a decent
afternoon/evening Delta Breeze for this weekend...yeeesss!

Hazy conditions will continue due to the Soberanes Fire just
south of Monterey Bay. Models indicate the southwest flow aloft
will persist through Tuesday which will bring elevated smoke to
at least the Southern Sacramento and Northern San Joaquin Valleys.
The San Joaquin Valley Air Pollution Control District is
continuing their Air Quality Alert for San Joaquin county and
southward into Monday.   JClapp/Wilson


.EXTENDED DISCUSSION (Wednesday through Saturday)
Dry weather expected Tuesday through Friday. Broad upper
troughing main synoptic feature through the extended forecast
period. This will result in seasonable temperatures with some
Delta flow and influence into the interior. High temperatures
expected mainly in the 90s for the Central Valley except around
100 in the Northern Sacramento Valley. Max temperatures for the
foothills and mountains forecast from the 70s at the highest
elevations to lower 90s at the lowest.


VFR conditions the next 24 hours. Light winds this morning will
become south to west 5-15 kt this afternoon and evening across
Valley TAF sites. SW gusts to 25 kt continue near the Delta.
