Area Forecast Discussion
National Weather Service San Francisco Bay Area
410 AM PDT SAT JUL 23 2016

.SYNOPSIS...Dry weather conditions along with above average inland
temperatures will persist through the weekend as high pressure
dominates the weather pattern. Meanwhile, onshore flow and marine
influences will maintain seasonably cool conditions near the
coast.

&&

.DISCUSSION...as of 04:10 AM PDT Saturday...Mostly clear
conditions persist over the region this morning as the marine
layer remains shallow after mixing out yesterday. Should see some
low clouds develop along the coast through sunrise, yet do not
expect them to spread much inland. Given the clear skies,
temperatures have cooled into the 50s to lower 60s region-wide.

Mid/upper level high pressure over central and southern
California will again result in warm to very warm inland
temperatures this afternoon. Expecting widespread 80s and 90s over
inland areas with a few of the warmest valley locations and hills
of southern Monterey and San Benito Counties approaching the 100
degree mark. Meanwhile, onshore flow near the coast will maintain
seasonable temperatures generally in the 60s to 70s. Most
locations will cool by a few degrees on Sunday as a weak mid/upper
level short-wave pushes inland to our north. However, do expect
inland areas to remain above seasonal averages. This feature may
also help to deepen the marine layer Sunday into Monday and result
in a slight increase in coastal stratus that will spread locally
inland. The slight cooling trend will continue into Monday given
increased onshore flow in response to the short-wave trough to the
north and weakening of the mid/upper level ridge.

The persistent ridge across the southwestern U.S. is forecast to
rebuild westward for the second half of next week. This will
maintain dry weather conditions and allow for another slight
warming trend, especially over inland areas. Overall, coastal
areas and those around the bays should continue to see seasonable
conditions while inland areas again bounce back above seasonal
averages late in the forecast period.

.AVIATION...as of 10:30 PM PDT Friday...Satellite image shows
clear skies except for the fire south of MRY. With a 6.4 mb
gradient ACV-SFO it is unlikely there will be clouds in the SFO
Bay Area tonight. The coast is clear as well so have removed
clouds for MRY and SNS but this will still have to be monitored.

Vicinity of KSFO..VFR.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals...VFR.

&&

.MARINE...as of 10:30 PM PDT Friday...Northwesterly winds are
expected to continue to increase tonight as the surface pressure
gradient strengthens. Moderate to strong northwesterly winds are
then expected to persist through the weekend. Some of the
strongest winds are anticipated along the Big Sur Coast where gale
force gusts will be possible. Sea conditions will deteriorate as
winds increase.
