Synopsis A cooling trend can be expected through Friday as
high pressure weakens and the marine influence increases. Minor
warming is then expected during the upcoming weekend into early
next week as high pressure returns to the west coast.

Discussion As of 3:30 am pdt Wednesday... Another round of
widespread clouds at the coast plus through most of the salinas
valley and into much of san francisco bay. Marine layer continues
to be around 1,500 feet along with a moderate onshore flow (sfo-
sac gradient over 3 mb) at the surface. Clouds will burn-off
toward the coast later this morning although similar to the past
few days, some locals beaches will not see any sunshine.

Biggest change compared to yesterday will be cooler conditions
inland as an upper level low and associated longwave trough
continue to dive southward into the northern rockies. Highs will
only be in the 70s to the lower 80s for inland locations with
upper 50s to upper 60s closer to the coast. The influx of cooler
air will lead to breezy conditions during the afternoon. Another
round of coastal clouds can be expected tonight.

Additional inland cooling is forecast for Thursday and Friday as
the trough dives farther to the south. Far inland spots will
struggle to get into the 70s while coastal areas will be in the
mid 50s to the mid 60s.

A ridge of high pressure will rebuild across our region starting
on Saturday and continuing at least into Monday. Many inland
locations will return to the upper 70s to around 90. Clouds along
with a continued onshore flow will keep towns near the coast
considerably cooler.

No sign of rainfall through the first week of june.

Aviation As of 4:30 am pdt Wednesday... Deep stratus intrusion
this morning, bringing widespread vlifr to ifr CIGS to most taf
sites. Generally speaking, marine layer is both deeper and has
lower ceilings this morning and will take longer to mix out today
versus yesterday. Some locations, ie along immediate coast such as
khaf and kmry will likely remain ovc010 or less through the entire
day. Otherwise, increasing west to southwest winds along the
coast becoming breezy to occasionally gusty in the
afternoon evening.

Vicinity of ksfo... Ifr to MVFR CIGS thru the mid morning, mixing
out toVFR between 18-19z. Tower will have better conditions than
the bridge which could impact approach until late morning. W-sw
winds up to 15kt with gusts to the low 20kts.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Stratus through the day along the coast,
with mixing out by mid to late morning further inland. Breezy
southwest winds through the afternoon and evening. Ceilings down
to 200-300 ft this morning tonight.

Marine As of 04:25 am pdt Wednesday... Increasing southerly
winds along the coast today. Surface high pressure bringing
northerly winds further offshore north of point reyes. A small
northwest swell moves through the water this week.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
