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 10:43 pm pdt Wednesday... Satellite image shows
a strong northerly flow with low clouds along the coast from san
francisco south impacting the mry bay area terminals. Clouds are
currently not impacting the bay area but is close enough to sfo
that a slight shift in winds could bring low clouds into sfo.

Therefore tempo MVFR CIGS were added to sfo.

Vicinity of ksfo...VFR through the airport evening rush. MVFR
cigs possible between 12z-16z with bases 1500-2000 feet.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Strong onshore flow allowing for early
MVFR cigs. MVFR CIGS through 18z.

Marine As of 10:29 pm pdt Wednesday... Low pressure over the
southern california interior will move into the great basin on
Thursday. Strong northwest winds on the back side of the low
including gale force winds over the northern waters will decrease
Thursday night. A large northwest swell will persist through the
end of the week particularly over the northern and outer waters.

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.
