Area forecast discussion 
National Weather Service San Francisco Bay area 
515 PM PDT Friday Jun 24 2016 

Synopsis...high pressure aloft will continue to influence the 
weather across the district for the next week. Aside from night 
and morning coastal low clouds, a modest warming trend is 
forecast through the weekend for inland areas with building high 
pressure and some light northerly winds. High pressure stays in 
place next week with continued dry and seasonably warm weather. 

&& of 2:50 PM PDT Friday...under sunny skies, area 
temperatures are still running a little behind what they were 
yesterday at this time. Early afternoon readings are ranging from 
the lower 60s at the coast to the 70s and 80s inland, with a few 
places in the 90s well inland. Surface pressure gradients continue 
to the strong from the north with 5.4 mb between acv and sfo, and 
13.3 from sfo to las. The strong northerly gradient should keep 
any coastal stratus that forms overnight from extending far 
inland. Expecting the coastal low clouds to reform tonight but the 
strong offshore gradient across the southern portion of the state 
should push clouds out over the water south of about Point Sur. 

The upper level ridge over the west will continue to influence 
the forecast area through the remainder of the forecast period 
with night and morning coastal stratus keeping near-shore areas 
seasonally cool, and warm to hot temperatures inland. There will 
be slight changes in the high temperatures each day, but only by 
a couple of degrees. Warmest inland locations are expected to top 
out over 100 degrees some of the days mainly over the weekend and 
early next week this week, with mid to upper 90s other days. 60s 
and 70s are expected near the ocean. 

&& of 5:15 PM PDT Friday...low clouds had completely 
cleared from the coast by late Friday afternoon and the north-S 
surface pressure gradient is sufficiently strong to prevent low 
clouds from developing inland overnight. It's therefore likely 
that VFR conditions will persist through the forecast period at 
most terminals. Only terminals close to the ocean have a chance of 
developing low ceilings late tonight into Saturday morning. Moderate 
afternoon and evening seabreeze winds will prevail, otherwise 
winds will be light. 

Vicinity of ksfo...VFR except possible IFR ceilings in the vicinity of 
ksfo for a few hours on either side of sunrise Saturday morning. 
West winds gusting to 25 kt through 04z and again after 22z on 
Saturday. Confidence moderate to high. 

Sfo bridge approach...similar to ksfo. 

Monterey Bay terminals...VFR except possible IFR cigs between 
06z-17z late tonight and Saturday morning. Confidence moderate. 
Light westerly winds. 

&& of 01:38 PM PDT Friday...moderate to locally strong 
gusty northwest winds will prevail along the California coast 
today and into tomorrow. The strongest winds will be over the 
outer waters at least 10nm from the coast. Steep choppy seas are 
expected to prevail across a majority of the coastal waters due to 
these strong winds. A long period southerly swell will also move 
through the waters over the next few days...resulting in breaking 
waves at nearshore reefs and sand bars.
