Seasonably cool conditions, onshore flow, and a modest marine layer

are expected this weekend and into next week. This will support

low-end moderate to good minimum relative humidity  with excellent

recovery for the coast and valleys. Above  the marine layer in the

higher terrain, poor minimum relative  humidity with low-end

moderate recovery is expected overnight.





...Discussion from SFOFWFEKA...



Warmer than normal temperatures return today and will persist into

the early part of the week. Winds will generally  be terrain driven

with typical afternoon west to northwest breezes.  There is a low

potential for thunderstorms returning as early as Sunday and

continuing through Wednesday as tropical moisture moves into the

region.
