Synopsis Seasonably cool temperatures will continue into
Friday with a deep marine layer near the coast. Seasonable
temperatures on Saturday should trend warmer inland by Sunday and
memorial day Monday. Aside from the isolated coastal drizzle, dry
weather forecast through the next 7 to 10 days.

Discussion As of 9:00 pm pdt Thursday... Cool temperatures were
observed across the region today with most locations topping out
in the mid 50s to mid 60s. Warmest inland locations reached into
the low 70s. It was a mixed bag of trends with some locations
warming a few degrees with others cooling as much as 22 degrees
over yesterdays temperatures. The deep marine layer allowed for
significant inland intrusion of the cool marine air and cloudy
conditions limited the amount of, if any, sunlight to reach the
ground. Low pressure over the region will maintain the deep and
undefined marine layer across the region through Friday and hence
similar temperatures to those that were seen today. Coastal
drizzle will once again be possible Friday morning.

The upper level trough that currently dominates the western united
states is forecast to begin moving eastward on Friday. This will
allow a shortwave ridge to build over california beginning
Saturday, and result in a modest warming trend for inland areas
over the memorial day weekend. However, coastal areas are not
expected to warm much over the weekend since onshore flow will
continue, along with a persistent marine layer.

Longer range models indicate the arrival of a trough along the
west coast around the middle of next week which should result in
at least slight cooling for inland areas during the second half of
the week.

Aviation As of 10:40 pm pdt Thursday... A deep marine layer and
southerly low level onshore flow will maintain widespread MVFR
ceilings across the region overnight and into Friday morning.

Low clouds are expected to scatter out in most areas by late
Friday morning or early Friday afternoon. Winds will generally be
light from the south and southwest.

Vicinity of ksfo... MVFR ceilings expected to develop by 07z and
continue until about 17-18z Friday. However, southerly flow over
the santa cruz mountains may result in sufficient downslope
warming and drying to delay development of low clouds and lead to
earlier clearing on Friday. Light southwest winds overnight and
into Friday morning, increasing in the afternoon.

Sfo bridge approach... Similar to ksfo except likely earlier
development of ceilings this evening.

Monterey bay terminals... MVFR ceilings expected overnight and
through Friday morning with likelyVFR conditions during Friday
afternoon, followed by early return of low clouds Friday evening.

Light south to southwest winds.

Marine As of 07:48 pm pdt Thursday... Gusty south to southwest
winds along the coast and over the bays will diminish through the
late evening. Generally light winds are then expected overnight
and into Friday. High pressure will redevelop over the eastern
pacific late week and into the memorial day weekend bringing a
return to more typical afternoon and evening onshore winds to the
coastal waters and bays.

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.
