Synopsis Typical bay area weather pattern expected through the
weekend and into next week. Expect areas of night and morning low
clouds and fog followed by sunny afternoons. Temperatures will be
near seasonal averages.

Discussion As of 9:05 pm pdt Saturday... A weak upper level
disturbance moving from south to north up along the california
coast generated a line of showers over our southern coastal waters
late this morning and afternoon, with isolated showers extending
over monterey county as well. In addition, an isolated
thunderstorm developed over the coastal waters west of monterey
bay around 2:30 this afternoon. Current radar shows that all
shower and thunderstorm activity has ended as the disturbance
moves north of our area. No additional convective activity is
expected in our area.

An upper trough is currently located offshore along 130w. This
trough is forecast to track to the ene and across northern
california on Monday. As it approaches the coast, expect
continued deepening of the marine layer and thus a continuation of
our inland cooling trend through Monday. In fact, by Monday high
temperatures for inland areas are forecast to be about 5 degrees
cooler than normal, a big difference from the triple-digit heat
that occurred during our recent prolonged heat event.

Temperatures are forecast to gradually warm from Wednesday
through Friday of next week as the upper trough moves off to our
east and is replaced by an upper ridge. However, temperatures are
only expected to climb to levels near or slightly warmer than
normal.

No precipitation is expected through the forecast period except
perhaps for patchy night and morning coastal drizzle from the
deep marine layer over the next few days.

Aviation As of 10:45 pm pdt Saturday... For 06z tafs... A 1600
ft marine layer coupled with moderate onshore flow will result in
cigs across most area terminals by morning. High clouds streaming
in from the south will continue to push north and out of the area
with little consequence. Low clouds will scatter out across most
terminals around 17z.

Vicinity of ksfo... Ifr CIGS will prevail through the night then
scatter out around 17z Sunday morning. Moderate west winds around
10 to 15 kt will gradually ease to around 10 kt overnight. West
winds will increase once again Sunday afternoon to around 15 to 20
kt with the onset of the seabreeze.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Lifr CIGS are in for the night. CIGS and
vsbys are forecast to drop to lifr vlifr after 11z tonight.

Conditions will begin to improve after 15z Sunday morning with low
clouds scattering out around 17z Sunday morning. Light west
winds.

Marine As of 8:57 pm pdt Saturday... Light northwesterly winds
and seas will prevail across the coastal waters through the
weekend and into early next week. Strongest winds are expected
along the big sur coast where a coastal jet is forecast to set up
and prevail through the weekend.

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.
