.[quote]Initial round of marine surge to be backed up by a slightly more determined push on THUR AM. All bets lean on Delta / East Bay.
Little wave of cooling was felt today across the region as marine air began its infiltration. SAT imagery shows a tongue of low level fog now passing Maverick's and stealthily creeping up the coast. Expecting this development to flourish overnight and really fill in across the South and Central Bay by THUR AM. Conventional wisdow dictates that these early fall marine surges tend to fall a bit short so won't go crazy w/ the numbers for Delta winds.
ï Sherman Island: Central Valley hit upper 90s WED PM. Any cooling to the west should trigger at least early 20-25kt pace for Delta but whether it can hold on all day is the big question. With trend FRI seeing more onshore flow, we'll fill in the PM period w/ mid 20s however.
ï Central Bay: Noticeable increase in AM fog w/ push past Angel Island likely. Slow clearing w/ best upper teen PM winds presenting 2nd half of bay.
ï Peninsula: Remains off the mark w/ late AND shifty upper teens out in the channel. Tough to reach w/ unreliable nearshore winds.
ï East Bay: Should see fog burn-back to the turn w/ a pretty decent round of Isabel / Berkeley / Larkspur breezes during the PM.
ï Coast: Pretty well socked in most of the day w/ northerly gradients still tight across offshore waters
