Synopsis Dry weather and seasonable temperatures are forecast
today and tomorrow. Cooler conditions along with a slight chance
of showers can be expected on Wednesday.

Discussion As of 3:00 pm pdt Monday... Widespread clouds
overnight for many spots with the marine layer still at 1500 feet
plus a moderate onshore flow. Similar to yesterday, most spots are
in the 50s and should see lows mostly in the upper 40s to the mid
50s by day break.

Today will be a near repeat of yesterday with clouds forecast to
slowly burn-off toward the coast by late in the morning. Yesterday
turned out to be a bit of a surprise in the east bay with a very
late transition to sunny skies. Models hint at the possibility
again today which could keep temps running a bit lower than
forecast. Outside of that, no issues anticipated with highs
expected to range from the 50s and 60s at the coast up to the 70s
and lower 80s inland. A few locations well inland could get into
the mid to upper 80s. Tonight will feature another round of patchy
fog and drizzle mainly near the coast.

Synoptically an upper level low will works it's way to the bc
coastline while an associated trough advances to the west coast.

Ahead of the main trough, a weak shortwave will move through on
Tuesday which will start to deepen the marine layer and provide a
degree or two of cooling. More substantial cooling (especially
inland) can be expected on Wednesday as the main trough moves
onshore. At the same time enough instability and associated
moisture could lead to a few showers late Tuesday into Wednesday,
although latest guidance has backed off a bit. Winds will also
pick up on Wednesday as the onshore flow increases. Westerly winds
of 10 to 20 mph with local gusts to 30 mph can be expected.

A weak ridge of high pressure will start to rebuild into our
region going to the end of the week. Highs will return back to
near normal levels.

Aviation 04:25 am pdt Monday for 12z tafs... Widespread clouds
with solid marine layer and mainly ifr conditions. Clouds will be
slow to clear today and the immediate coast may not clear at all.

Gusty onshore flow later today. CIGS return tonight.

Vicinity of ksfo... Ifr CIGS through 19z withVFR there after.

Guidance still shows strong west winds this afternoon with gusts
up to 25 or 30 kt. CIGS return early tonight.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Ifr CIGS through this morning. CIGS will
gradually lift, but conf is low that any clearing will occur at
kmry more likely at ksns. Winds will increase Monday afternoon
out of the west at 10 to 20 kt. CIGS return early tonight.

Marine As of 04:23 am pdt Monday... Strong high pressure over
the pacific and low pressure over southern california will result
in gusty northerly winds over the coastal waters. The gusty winds
will produced hazardous conditions with steep winds waves and
fresh swell. Winds will decrease mid week as a weak frontal system
moves through the coastal waters.

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.
