Synopsis Increasing clouds later this afternoon and evening
ahead of the next weather system. Rain showers will develop after
midnight into Sunday morning. Showers and isolated thunderstorms
continue on Sunday with cool daytime temperatures. Dry but cool
for memorial day. Gradual warming trend to near normal for the
work week with dry weather forecast.

Discussion As of 2:02 pm pdt Saturday... Interesting weather
pattern across california today. Earlier this morning there was
some showers and storms over northeast california with activity
firing over the northern sierra by midday. Meanwhile some rogue
thunderstorms are now firing in the southern san joaquin valley.

The bay area is seeing a nice Saturday with temps now warming into
the upper 60s and 70s away form the coast. Lingering coastal
clouds in the usual spots from half moon bay to monterey has kept
temps stuck in the upper 50s along the beaches.

All attention is on shortwave currently rotating west of astoria
oregon. For those watching from home this feature shows up nicely
on the goes-17 water vapor imagery. It'll be a blustery Saturday
evening as onshore winds and clouds increase ahead of this
incoming weather system.

All available model guidance shows showers developing after
midnight tonight as the core of the upper low reaches the north
bay by morning. Many areas should wake up to wet roads and the
pitter-patter of raindrops early Sunday morning. Showers and
isolated thunderstorms will continue on Sunday but there should be
a drying trend for the north bay by midday as the upper low drops
south. Rain totals on average of 0.10-0.25 with some areas
receiving no rain given the convective nature of the rainfall.

Even areas that remain dry on Sunday will be unseasonably cool
with highs in the upper 50s to mid 60s most locations.

Drying pattern develops by Sunday night but it'll be chilly in the
wake of the cold upper trough. Memorial day Monday looks dry but
continued unseasonably cool with highs mainly 60s and some lower
70s.

Next week should see a gradual return to more seasonable
temperatures but not seeing any real warm weather with a general
trough over the west coast.

Aviation As of 05:25 pm pdt Saturday... Marine stratus covers
much of the coast south of san francisco, otherwise skies are
clear to partly cloudy.VFR conditions currently prevail at all
sf bay area terminals, while MVFR ceiling onset has already
occurred at kmry and ksns. Very unusual weather circumstances for
this time of year to be developing late tonight into Sunday, as a
cold winter-like upper low plunges southward into our area. It
will bring gusty onshore winds, periods of -shra and shra, and
even a possibility of some thunderstorms and small hail. Primary
impacts look to be south of san francisco during the day on
Sunday.

Vicinity of ksfo...VFR conditions with moderately strong and gusty
onshore winds are forecast to continue through the evening rush,
but can't completely rule out the possibility of an earlier
short-lived MVFR cloud deck spilling through the gap into the
terminal area. With the approaching storm system, expect winds to
actually increase significantly out of the west during the late
night and morning hours, becoming strong and gusty, along with
developing rain showers.

Sfo bridge approach... Similar to ksfo, though more confident the
approach will remain clear through the evening hours than the
terminal itself.

Monterey bay terminals... MVFR ceilings are expected to prevail
through the night and into Wednesday morning. Risk of lowering to
ifr however is considered to be pretty low. With the approaching storm
system, expect winds to strengthen out of the west during the late
night and morning hours, becoming moderately strong and gusty,
along with developing rain showers.

Marine As of 01:42 pm pdt Saturday... Gusty northwest winds will
continue today and tonight with gale-force winds over the
northern outer waters. Scattered showers and isolated
thunderstorms are possible on Sunday. Moderate northwest swell
will continue through the weekend with steep fresh swell generated
by the gusty winds.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
