.DISCUSSION...
High pressure will remain the primary feature through the weekend
and into early next week. Any patchy/shallow fog that has been
able to develop overnight will quickly erode/dissipate within an
hour after sunrise. Southeast sfc winds between 5-10 mph are
expected by mid morning, then could gust up to 15-20 mph early to
mid afternoon as a sea breeze shifts inland and across the spot
location with little change in wind direction. Sfc winds return
to around 10 mph by sunset and slowly weaken during the night.

Fog potential for tonight: Low
