National Weather Service San Francisco Bay area 
817 PM PDT Tuesday Apr 15 2014 

Synopsis...dry conditions and near seasonal daytime temperatures 
will continue across the region through this upcoming weekend as 
upper level high pressure remains over the West Coast. Low clouds 
and patchy fog will continue to impact coastal locations and adjacent 
valleys during the overnight and early morning hours. 

&& of 8:10 PM PDT Tuesday...high pressure covers the 
area. The northerly pressure gradient has steadily increased to 7 mb 
this evening. The onshore gradient has increased by about 1 mb 
stronger than yesterday evening at this time...presently 2.7 mb. 
Clouds persisted many places this morning but have since cleared 
with the exception of low clouds persisting over the southern part 
of the Monterey Bay waters. 

Dry weather and mainly clear to clear skies will prevail through 
middle-late week. The jet stream will keep the storm track well to 
our north for most if not all of the upcoming forecast period. 
Daytime high temperatures will range from the 60s coast to the 70s 
and even some lower to middle 80s well inland Wednesday and 

&& of 4:41 PM PDT Tuesday...the current visible 
satellite image is showing clear skies over most areas except for 
some patchy coastal stratus from about the Monterey Bay south. The 
north to south surface pressure gradient has ramped up to over 6 
mb from acv to sfo...thus expect less in the way of stratus impacts 
across the Bay area taf locations tonight. There could be some 
ceilings over San Jose and Oakland late...and stratus will impact the 
Monterey and Salinas terminals overnight. 

Vicinity of ksfo...VFR is expected to persist through the forecast 
period with MVFR conditions developing late to the east of the 
terminal and approach. West winds 10 to 20 knots will decrease this 

Ksfo bridge approach...similar to ksfo. 

Monterey Bay area terminals...VFR is anticipated through early 
evening. Then MVFR/IFR ceilings will impact the Airport by late
