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 and isolated thunderstorms possible on Sunday.

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

Discussion As of 3:38 am pdt Friday... The shower activity from
last evening has ended, although moderate drizzle is occuring
along the coast, especially around the monterey peninsula. Aside
from this coastal drizzle in the morning, today is expected to be
dry with more Sun and slightly warmer temperatures compared to
yesterday. Similar conditions are expected on Saturday.

Another upper low center is then forecast to affect the area on
Sunday as it drops south along the coast. Models are coming into
better agreement concerning the placement of this low, and it is
looking pretty plausible to see showers once again on Sunday.

Latest guidance focuses the main area of precip over the southern
and western-most portions of the district, mainly from marin
county south. In addition to showers, there is the potential for
isolated thunderstorms on Sunday, again mainly across the southern
half of our forecast area, closer to the upper low center.

Rainfall totals with this weekend's system will depend on the
exact track of the system and how far west the low tracks. Snow
levels will also depend upon the track of the low center. The
latest forecast keeps snow levels above 5000 feet, so any snow
fall would occur over the highest peaks in the santa lucias.

Temperatures on Sunday are forecast to be as much as 20 degrees
below normal.

The upper low is forecast to move well off to the southeast of
our area by Monday. Thus, dry weather is expected to return by
memorial day. Temperatures will warm slightly on Monday, but still
remain well below normal. Cool conditions are expected through the
remainder of the week as a broad upper level trough remains over
the west.

Aviation As of 05:05 am pdt Friday... Southerly to
southwesterly flow continues along the coast. Downsloping has kept
sfo and sjc inVFR overnight while other sites are experiencing
MVFR cigs. Satellite indicates little expansion of the stratus in
the past few hours with a large hole in the stratus advecting up
the coast from the south west of monterey bay. Southerly flow
expected to weaken this morning and turn westerly by this
afternoon. Southerly flow may keep sts in MVFR CIGS into the
early afternoon while sfo and sjc may see predominantlyVFR
through the morning and into the afternoon. Expecting onshore
winds of 10-15 kt this afternoon at most sites.

Vicinity of ksfo...VFR most likely to prevail over the terminal
through the morning. Stratus over oak has shown little westward
expansion towards sfo overnight. If southerly flow weakens may see
a brief period of MVFR CIGS this morning. Light southerly winds
will turn westerly 10-15 kt this afternoon.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... MVFR CIGS this morning with occasional
drizzle possible. Latest satellite trends a hole in the stratus
and drier air moving north along the coast. Some of this drier air
may work its way into the terminals and cause an earlier burn off
of stratus than indicated in the taf. Will continue to monitor
this development.

Marine As of 2:40 am pdt Friday... Gusty northwest winds will
continue to decrease over the northern outer waters this morning
with light winds elsewhere. 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.

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.
