national weather service san francisco bay area
516 pm pdt Wed may 22 2019

Synopsis Temperatures will be on the warming trend through the
remainder of the week, yet will remain below seasonal averages.

Unseasonably cool and unsettled conditions continue into the
upcoming weekend with a renewed chance of rain showers as another
system drops southward across the region.

Discussion As of 01:45 pm pdt Wednesday... Radar has been
switched back to clear air mode for the time being as shower
activity has exited to socal. Satellite imagery shows mostly sunny
skies across the bay area with widespread cumulus clouds from the
south bay southward. Increased sunshine, warmer airmass and lack
of precip has led to warmer temperatures this afternoon with many
locales running 5 to 10 degrees above Tuesday's maximum temps.

Once the Sun sets expect the cumulus to diminish with mainly clear
skies in the heart of the bay area with more clouds likely around
monterey bay. If the higher res models verify overnight, breezy to
gusty NE are forecast over the north and east bay higher terrain.

Gusts over 30 mph are possible.

The longwave pattern keeps a broad upper trough over the region
surprisingly into early next week. Temperatures will warm a few
more degrees on Thursday returning closer to normal. Highs will be
in the 60s to mid 70s. Several models rotate a weak shortwave
around the base of the upper trough Thursday afternoon. There will
likely be enough lift to support a few pop up showers or an
isolated thunderstorm over gabilan range during peak heating.

As noted on the previous discussion additional disturbances
rotate around the trough as well bringing additional precip
chances to the state. A few showers may drift westward in the
forecast area on Friday and early Saturday. Another upper low
takes aim at the bay area again late in the weekend providing a
better chance for precip late Saturday and more so on Sunday. It
doesn't look like a total wash out at this point for the holiday
weekend, but more showery in nature.

Memorial day looks cool with a few isolated showers. Warmer and
drier will develop Tuesday and Wednesday.

Aviation As of 5:13 pm pdt Wednesday... Mid level moisture
wrapping around an upper low over the southwest is causing
afternoon cumulus clouds to form. The clouds are scattered but
there could be small patches where it is bkn. These clouds should
dissipate after dark.

Strong onshore flow on the back side of the upper low will allow
stratus or stratocumulus to form late tonight. Could see sct-bkn
conditions at times over the bay area between 06z and 16z. West
winds gusting to 20 kt through 04z.

Vicinity of ksfo...VFR through the airport evening rush. MVFR
cigs possible over the approach between 12z-16z. West winds
gusting to 20 kt through 04z.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Strong onshore flow will allow for early
MVFR cigs. MVFR CIGS after 02z at mry and 04z at sns.

Marine As of 04:39 pm pdt Wednesday... A large, moderate period,
late season northwest swell is moving across the waters today.

Breakers of up to around 20 feet are possible. In addition,
increasing northwest winds with gale force gusts are forecast
across the northern and outer waters through the near term.

Moderate wind and seas will persist through the end of the week,
particularly in the northern outer waters. Hazardous conditions
from squared seas will exist after the winds begin to diminish.

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.
