917 am pst Wed jan 23 2019

Synopsis Building high pressure along the west coast will
result in a gradual warming trend through Saturday, along with
mainly clear skies. The dry weather pattern will likely last
through the end of the month, with a continuation of seasonably
mild days and cool nights.

Discussion As of 09:06 am pst Wednesday... The ongoing forecast
in the short-term remains on track and no updates are anticipated
at this time. Please see the previous forecast discussion for
additional details.

Prev discussion As of 2:42 am pst Wednesday... Upper level high
pressure continues to build off the west coast. Latest overnight
satellite imagery shows a few high clouds spilling over the
periphery of the ridge. Despite a few high clouds spilling into
far norcal, much of the bay area is mostly clear. Clear skies and
relatively light winds will lead to a chilly morning. For what
it's worth the latest 24 hour trend does indicate many locations
are currently running cooler than 24 hours ago - mid 30s to 40s.

Given the clear skies and light winds temperatures are likely to
drop a few more degrees through shortly after sunrise patchy frost
is possible.

The upper level ridge is forecast to remain over the region and
ultimately strengthen moving inland this weekend. There is a
brief ripple late in the week with a weak inside slider, but the
next result locally is offshore flow. Therefore, the rest of the
work week and next weekend will be rather quiet weather wise.

Clear skies and dry conditions will prevail. Temperatures will
gradually warm through the period and peak Friday-Sunday with
periods offshore flow. Temperatures will warmer to above seasonal
levels with highs in the 60s and 70s. Overnight lows on the other
hand will remain cool to chilly with clear skies and light winds.

The question is, when will it rain next? The 00z operational runs
of both the ECMWF and GFS keep the bay area dry through 240 hours
(feb 1). However, some of the ensemble guidance gives a 25% chance
of 0.01" at ksfo around feb 1 or 2. Needless to say the extended
forecast will need some watching, but confidence does seem pretty
high that the region will remain dry through then end of january.

Aviation As of 9:18 am pst Wednesday... For 18z tafs. High
pressure will maintain mainly clear skies across area terminals
with the exception of a few high clouds. Generally light winds
will prevail through the forecast period.

Vicinity of ksfo...VFR conditions will prevail through the period
with only a few high clouds expected. Light to locally variable winds
will persist.

Sfo bridge approach... Similar to sfo.

Monterey bay terminals...VFR conditions and light winds will
prevail through the period.

Marine As of 8:28 am pst Wednesday... High pressure over the
eastern pacific will generate moderate to locally gusty northerly
winds across the coastal waters through much of the week. A series
of small to moderate northwest swells are forecast throughout the
week.

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.
