Synopsis A building ridge of high pressure will lead to warmer
weather across our entire region especially after Sunday.

Discussion As of 2:00 pm pdt Friday... Mostly sunny skies across
our entire region today with a moderate northerly gradient in
place at the surface along with no marine layer plus a longwave
trough overhead. Temperatures are very close to this time
yesterday -- 60s to the lower 70s.

Synoptically a substantial change will take place over the next
few days at the trough progresses to the east while a strong
ridge of high pressure builds to the west coast. At the same time
850 mb temperatures will rise from around 7c all of the way to
over 20c. This will lead to a pronounced increase in temperatures
for all areas including down at the coast. By Tuesday spots near
the coast will be in the 80s while inland areas will be in the
90s. Currently there are not any indications that temperatures
will warm much beyond the values that are forecast (in fact the
forecast is above almost all of the guidance). Worst case
(hottest) values from the eps show potentially another 3 to 5
degrees of warming which would still fall short of the past two
heat events. However, we will keep a close eye to see if the
values trend higher.

The other issue will be lower humidity values that will combine
with breezy conditions as offshore winds increase. Models are
focusing the highest speeds and poorest recoveries along the north
bay hills beginning Saturday afternoon and continuing at least
into Monday. With nighttime MAX values of just 30 percent (or even
less) critical fire weather conditions can be expected. A fire
weather watch is now in effect for that region.

Longer range guidance through the following week favors warmer
than normal temperatures with dry conditions. Even guidance beyond
that continues that pattern through the following week.

Aviation As of 4:14 pm pdt Friday for 00z Saturday
tafs... Aside a few possible sct and perhaps locally bkn clouds at
sunrise tomorrow along the coast,VFR conditions are expected to
prevail throughout the san francisco bay area and central
california coast over the next 24 to 30 hours. Breezy onshore
winds will diminish after sunset, and increase again on Saturday
afternoon. High confidence.

Vicinity of ksfo...VFR conditions expected. Breezy west winds this
evening around 15 kt will decrease after sunset.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals...VFR conditions expected, though there is
a slight possibility of some brief sct or even bkn skies around
sunrise Saturday. Likelihood of occurrence at kmry or ksns is too
low to put into taf, but will monitor and amend if necessary.

Breezy onshore winds will decrease after sunset.

Fire weather As of 2:39 pm pdt Thursday... Clear and cool
overnight with easing northwest winds. Continued dry and
seasonable on Friday. By late Friday night northerly winds will
develop across the north bay hills into early Saturday morning but
humidity should stay fairly moist. Noted warming and drying trend
over the weekend with periods of gusty northeast winds across the
north and east bay hills later Saturday night and then again
Sunday night. Afternoon highs well into the 80s and lower 90s
inland areas with humidity lowering into the teens. Long range
trends show a prolonged yet seasonable warm and dry pattern
through the weekend and into next week with high pressure aloft
and a thermal trough near the coast. Fine fuels will continue to
dry given the lack of marine air. Climatology suggests potential
for near critical fire weather conditions for much of the next 5-7
days starting this weekend. Fire weather watches and or warnings
may become necessary should the pattern develop as expected,
however no strong offshore wind events are forecast at this time.

Marine As of 4:08 pm pdt Friday... Eastern pacific ridge will
gradually build towards the region, bringing breezy northwest
through the coming days, especially over the northern outer
waters. Northwest swell train will continue to weaken over the
coming days.

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.
