Synopsis Scattered showers and an isolated thunderstorms are
possible through this evening. Dry but cool conditions are
forecast for memorial day. A gradual warming trend is expected
early next week with temperatures expected to return to near
normal by midweek.

Discussion As of 01:21 pm pdt Sunday... A cold core upper level
low is passing over the bay area this afternoon. The low is
helping to produce widely scattered showers. Only two lightning
strikes near gilroy so far, but the central valley has had a
handful of strikes. There have been reports of heavy rain and and
small hail.

Shower activity will diminish north to south through this evening
as the upper low moves south. Winds will remain breezy through
this evening and then gradually diminish overnight. Given the
ample low level moisture some patchy valley fog is possible
overnight.

Dry and warmer weather is expected on memorial day with highs in
the 60s to lower 70. Higher peaks around the region will be much
cooler and in the 50s. Despite the warm up temps are still below
normal for late may.

Dry weather holds on through at least mid week as a ridge of high
pressure tries to build over the region. However a weak low
swings through the great basin Wednesday into Thursday. Models
keep the bay area dry, but do show some precip across the sierra.

After a period of unseasonably wet weather the official forecast
will be dry for much of the upcoming extended forecast.

Aviation As of 05:03 pm pdt Sunday... Convective showers will
continue late this afternoon and evening as a cold upper low moves
through the area. A thunderstorm occurred near gilroy earlier
this afternoon but lightning has not been detected elsewhere so
far. Showers will bring wet runways and ceilings briefly lowering
to MVFR. Showers will gradually end from north to south this
evening, with generally dry conditions expected north of monterey
bay by 06z. Occasionally gusty onshore winds this afternoon will
decrease becoming 5-10 kt by late this evening. Residual moisture
will result in ceilings returning late this evening and overnight.

Expecting CIGS between 2000-3000 feet by sunrise Monday. Cigs
will persist through the morning with clearing expected by early
afternoon at most terminals.

Vicinity of ksfo... Showers on the decrease with coverage ending by
mid evening. Brief MVFR will be possible with any showers.

Isolated vcts will remain possible through early evening. Breezy
onshore winds will decrease this evening with 5-10 kt expected
overnight. CIGS of 2000-3000 feet expected to return overnight and
persist through late Monday morning.

Sfo bridge approach... Similar to ksfo except clouds below 4000 ft
in approach may impact visuals.

Monterey bay terminals... Showers will continue this evening with
brief MVFR during showers. Breezy onshore winds will decrease this
evening. A few showers may linger into the overnight hours before
ending by sunrise Monday. MVFR CIGS will return late this evening
and persist through Monday morning and possibly Monday afternoon.

Marine As of 10:30 am pdt Sunday... A passing storm system
bringing breezy to locally gusty northwest winds across the waters
today. Unstable atmospheric conditions will result in showers and
isolated thunderstorms during the day. Moderate northwest swell
continues through the weekend with steep fresh seas generated by
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.
