Synopsis Dry weather and seasonable temperatures are forecast for
the remainder of the holiday weekend. Slight cooling is forecast
for inland areas on Tuesday and Wednesday, but otherwise little
change is expected through next week.

Discussion As of 8:50 pm pdt Saturday... The memorial day
weekend got off to a pleasant start with widespread sunny skies
developing by afternoon, along with warmer temperatures. But even
though temperatures today were as much as ten degrees warmer than
yesterday, they were still slightly cooler than normal in most
locations.

Low clouds have begun to fill in along the coast from san mateo
county northward. Moderate onshore flow, along with the latest
boundary layer relative humidity forecasts, suggest that low
clouds will become widespread near the coast overnight and develop
around san francisco bay and into most coastal valleys as well.

On Sunday inland areas will clear out by midday, but only partial
afternoon clearing is expected at the coast. Temperatures on
Sunday will be around persistence near the ocean, but a few
degrees warmer for inland areas as the airmass over our region
continues to warm under high pressure aloft.

Little change is expected on memorial day. By Tuesday a weak upper
trough is forecast to arrive over northern california. This
trough will cool the airmass across our region as well as enhance
onshore flow. The result will be cooler temperatures inland on
Tuesday and Wednesday. However, most model guidance indicates
little change at the coast.

For the most part, the weather pattern over the next week looks to
be one which will maintain seasonable temperatures and seasonably
dry conditions.

Aviation As of 10:30 pm pdt Saturday... Northwest flow spreading
stratus into the sfo bay area and approaching the mry bay area.

Upper level trough moving out of the area will result in a more
compressed marine layer tonight as ridging builds in. A little
earlier clearing Sunday.

Vicinity of ksfo... MVFR CIGS clearing by 17z.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Stratus approaching the mry bay area
from the northwest. This is a favorable direction for stratus and
ifr CIGS are expected after 09z. Clearing 17-18z.

Marine As of 10:30 pm pdt Saturday... High pressure will
strengthen off the california coast resulting in increasing
northwest winds Sunday. Winds will decrease Tuesday night as a
weak frontal system moves through the coastal waters.

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.
