124 pm pdt Sun may 26 2019

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 10:35 am pdt Sunday... Upper low over the area
today will bring convective showers through the day and the
potential for a few isolated thunderstorms between 19zsun-02zmon.

One strike has already been observed in a thunderstorm north of
sacramento in the central valley and this air mass is expected to
shift south across the sf monterey bay regions through the day.

Breezy onshore winds today (12-16kt) with occasionally gusty
winds (18-25kt) through this morning and early afternoon, with
stronger winds near coastal gaps and over higher terrain. Showers
will be sufficient in bringing wet runways and brief reductions in
visby. Ceilings will range mostly above the 3000 ftVFR threshold
but could see approach issues for ksfos thresholds of 4000 ft or
below as ceilings expected btwn 2500-5000 ft today. For tonight,
expect low to mid level moisture to manifest into bkn ovc clouds
at 2000-3500 ft by sunrise Monday.

Vicinity of ksfo... Showers with isolated vcts today. Wet runways
with brief MVFR CIGS visbys during showers. Breezy onshore winds
through the taf. Best chance of thunderstorms will occur during
the afternoon near ksfo. Overnight bkn ovc clouds down to 2000 ft
by sunrise Monday.

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

Monterey bay terminals... Showers through the day. Wet runways with
brief MVFR CIGS visbys during showers. Breezy onshore winds
through the taf. Best chance of thunderstorms during the afternoon
with lingering showers into this evening. Overnight bkn ovc clouds
down to 1500-2000ft by sunrise Monday.

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.

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.
