Area Forecast Discussion
National Weather Service San Francisco Bay Area
858 PM PDT Thu Apr 27 2017

.SYNOPSIS...Continued breezy conditions at times on Friday,
particularly near the coast and in the hills, with a gradual
warming trend. Winds will ease by Saturday morning then clear and
warm weather is forecast over the weekend and into early next week
with no rain in the extended forecast.

&&

.DISCUSSION...as of 8:55 PM PDT Thursday...A strong northerly
gradient continues to strengthen this evening as high pressure
builds off the Pacific Northwest coast. The gradient from ACV to
SFO is currently at 7.3 MB resulting in strong and gusty winds
along the coast and hills of the forecast area. Latest
observations in the North Bay mountains show sustained winds of 21
and 28 mph with gusts of 47 and 50 mph reported at the Middle
Peak and Big Rock RAWS, respectively. Elsewhere wind are in the 15
to 25 mph range with gusts of 25 to 35 mph. As stated before
strongest winds will remain along the coast and over elevated
terrain.

Strong winds will persist through tonight veering increasingly to
the north. Winds will ease slightly Friday before ramping up
again Friday afternoon as high pressure ridges over the Pacific
Northwest and settles in over the Great Basin. This coupled with a
thermal trough developing along the California coast will result
in strong and gusty winds out of the north to northeasterly. Gusts
of 35 mph or higher are expected across the North and East Bay
mountains.

High pressure will give way to mostly clear skies and slightly
warmer temperatures across the region Friday. Temperatures are
forecast to warm into the 60s along the coast to the mid 70s
inland. The warming and drying trend will kick it into high gear
over the weekend and into early next week as high pressure at the
surface and aloft take hold of the region. Temperatures are
forecast to top out in the 60s and 70s along the coast and mid 80s
inland. Monday and Tuesday appear to be the warmest days with
upper 80s to even a few 90s sprinkled over the warmest inland
valleys.

The pattern will see little change through the first half of the
week with the ridge beginning to break down around Thursday of
next week. Therefore use caution when outdoor and protect young
children and the elderly from dehydration, sunburns and heat
exhaustion.

.AVIATION...as of 4:38 PM PDT Thursday...Near high confidence dry
northerly winds will keep VFR going at the terminals tonight and
Friday. Only exception is there may be a few patchy low clouds
along the immediate coastline early Friday morning, otherwise VFR
is forecast with few-sct thin cirrus.

Vicinity of KSFO...VFR. Gusty W-NW winds near 30 knots this evening
gradually relaxes tonight, then resumes and becomes gusty from the
W-NW again Friday.

SFO Bridge Approach...VFR.

Monterey Bay Terminals...VFR. Patchy IFR cigs are possible over the
southern Monterey Bay area per WRF model output, KMRY tempo 12z-16z
BKN 800 feet.

&&

.MARINE...as of 7:42 PM PDT Thursday...Strong northwesterly winds
will impact the coastal waters today and Friday as building high
pressure tightens the pressure gradient. Some isolated gale force
gusts will be possible offshore and near coastal points. Steep
seas will develop in response to the winds and a fresh northwest
swell will continue to impact the coastal waters through the
weekend.
