Synopsis Temperatures will be on the warming trend through the
remainder of the week, yet will remain below seasonal averages.

Unseasonably cool and unsettled conditions continue into the
upcoming weekend, rain showers return Sunday.

Discussion As of 9:47 pm pdt Wednesday... Widespread cloud
coverage continues to wrap around a low pressure center located
over socal, the clouds cover much of california and extend across
the intermountain west. Dry weather has returned to the CWA and
highs today recovered to the point of similarly matching warmth
felt earlier this month. Highs and lows today were generally more
typical of mid to late may.

The closed 500 mb height low over socal will eject NE and merge with
a deeper 500 mb low over hudson bay later Friday night and Saturday.

Another pair of low pressure centers currently over southern alaska
and the gulf of alaska will pass by the northernmost extent of a high
pressure ridge over the eastern pacific, an imbalance of jet stream
winds will drive these low pressure systems southward along the west
coast Saturday and Sunday. The low pressure system arriving Sunday
will have more dynamic strength to it though since typically low
pressure systems arriving from the north are often moisture starved
this will tend to limit rainfall amounts. Both ECMWF and GFS agree
qpf amounts through late weekend will vary from 0.10" to 0.25" except
for isolated amounts possibly nearing 0.50" in heavier showers. On top
of positive water year anomalies the upcoming wet weather will of
course add to widespread may 2019 positive precipitation anomalies
across the cwa; utilizing a relatively small sample of data from the
airports within the CWA anomalies so far vary from 250% to 440% of
may normals.

Aviation As of 5:13 pm pdt Wednesday... Mid level moisture
wrapping around an upper low over the southwest is causing
afternoon cumulus clouds to form. The clouds are scattered but
there could be small patches where it is bkn. These clouds should
dissipate after dark.

Strong onshore flow on the back side of the upper low will allow
stratus or stratocumulus to form late tonight. Could see sct-bkn
conditions at times over the bay area between 06z and 16z. West
winds gusting to 20 kt through 04z.

Vicinity of ksfo...VFR through the airport evening rush. MVFR
cigs possible over the approach between 12z-16z. West winds
gusting to 20 kt through 04z.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Strong onshore flow will allow for early
MVFR cigs. MVFR CIGS after 02z at mry and 04z at sns.

Marine As of 04:39 pm pdt Wednesday... A large, moderate period,
late season northwest swell is moving across the waters today.

Breakers of up to around 20 feet are possible. In addition,
increasing northwest winds with gale force gusts are forecast
across the northern and outer waters through the near term.

Moderate wind and seas will persist through the end of the week,
particularly in the northern outer waters. Hazardous conditions
from squared seas will exist after the winds begin to diminish.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

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.
