Synopsis Mainly dry conditions are forecast through Saturday,
along with continued cooler than normal temperatures.

Unseasonably cool and unsettled conditions are forecast to develop
later in the weekend as a system drops in from the north, with
scattered showers maybe a stray thunderstorm possible on Sunday.

Dry weather should return by memorial day, but temperatures will
remain cool into early next week.

Discussion As of 1:32 pm pdt Friday... Visible satellite
imagery shows some areas of low clouds lingering over parts of the
san francisco and monterey bay areas this early afternoon. These
low clouds are preventing efficient solar heating thus far this
afternoon for some locations. For example, the sonoma county
airport (ksts) is running 12 degrees cooler than this time 24
hours ago as a consequence to the marine stratus. The most recent
satellite trends reveal that clearing is occurring in the north
bay valleys, but with the delayed sunshine, have gone ahead and
dropped afternoon maximum temperatures for most north bay
locations by several degrees. The east bay south of the bay bridge
as well as the south bay have been mostly sunny since mid-
morning, and are actually running several degrees warmer than 24
hours ago. By the time the afternoon wraps up, high temperatures
along the coast will warm to the upper 50s to 60s while interior
locations will warm to the middle upper 60s to middle 70s. These
values equate to about 3 to 9 degrees below late may
climatological normal values.

If you're looking for warm weather in the bay area for the
holiday weekend, I do not have good news for you. There is high
confidence of continued below normal temperatures through memorial
day as another upper level low drops south from the pacific
northwest by the second half of the weekend. This upper low will
bring a reinforced shot of cooler air, as well as another
opportunity of rain showers on Sunday. Snow levels will drop to
around 5,000 ft, per the official forecast and the national blend
of models (nbm); however, the 12z run of our local in-house wrf
drops snow levels to 4,200 to 4,500 ft for some locations. Just to
quantify how anomalous this upper low is -- the 850 mb
geopotential height levels over our area are forecast to
correspond to about -3 to -4 sigma (standard deviations) with
respect to the 1979-2009 climate forecast system reanalysis
(cfsr). At the surface, these temperatures will translate to about
10 to 20 degrees below normal. Hikers, campers, and outdoor
enthusiasts with plans to head to the higher elevations on Sunday
should plan accordingly for cold temperatures and rain showers, as
well as the possibility of isolated snow showers if snow levels
drop lower than the present official forecast. Will also have to
keep a close eye on the possibility of thunder for parts of the
area, but for now think the best odds will be to our east in the
sierra.

For memorial day, temperatures should begin to rebound as the
upper low exits the area with highs in the 50s and 60s along the
coast and middle 60s to near 70 for inland communities. Can't rule
out some lingering showers in the mountains during the day, but
think most locations will be dry for the holiday itself. Temperatures
will continue to moderate through the middle of next week with
the nbm bringing back some 80 degree readings returning to the
warmest locations by Wednesday or Thursday. With that said, though,
both the GFS and ECMWF are keeping a trough over the west coast, so
temperatures will likely just return back to near normal values.

There is hope for those waiting for warmer weather -- the climate
prediction center's 8-14 day outlook does begin to favor the
likelihood of experiencing above normal temperatures for the june
1 to 7 period.

Aviation As of 10:33 am pdt Friday... South flow will keep
clouds lingering for sts and monterey bay. Strato-cu continues to
fill in across portions of sf bay, which may impact ops at times.

Vfr for most locations later today, but sts may struggle to clear.

Cigs return tonight, but conf is low for sfo. Gusty winds develop
overnight too.

Vicinity of ksfo... A few CU spilling over sfo at 2k may briefly
impact operations, but it should be shortlived. Will keep bkn for
tonight, but conf is low as some models keep CIGS just N of sfo.

Cigs more likely for oak.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Slow burn off today and will keep cigs
late into the afternoon. A few hours of sct before early return of
cigs this evening.

Marine As of 09:57 am pdt Friday... Southerly flow will prevail
near the coast and with northerly flow over the outer waters
today. Low pressure will move inland over the great basin Friday
night through the weekend and lead to gusty northwest winds over
the coastal waters. Moderate northwest swell will continue through
the weekend with steep fresh swell generated by the gusty winds.
