Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... High pressure ridging over the pacific northwest will produce moderate northerly winds across the coastal waters through midweek. Strongest winds are expected across the northern outer waters. As high pressure builds in over the great basin during the second half of the week, a thermal trough will develop along the coast. This will result in light offshore flow across the coastal waters. A moderate northwest swell will continue through midweek.

area forecast discussion
national weather service sacramento ca
300 am pdt Tue oct 22 2019

Synopsis
Breezy conditions at times, especially Wednesday into Thursday
when elevated fire weather concerns are expected. Dry conditions
with above average temperatures forecast through the remainder of
the week.

Discussion
Broad ridge over the eastern pacific and norcal continues to
provide clear skies. Current temperatures range from the upper 20s
in the mountain valleys to the mid 60s across milder portions of
the central valley and foothill thermal belts. North to northeast
pressure gradients are a bit tighter compared to early Monday
resulting in gusts in the 15-25 mph range across the northern
sacramento valley and local gusts of 20-40 mph in the foothills of
butte county.

Warm and dry weather will continue this week with highs forecast
to be around 5 to 15 degrees above average. Overnight lows will
be mild across windier portions of the valley and in the foothills
thermal belts, but will be close to normal elsewhere.

The main concern this week is enhanced fire weather conditions,
especially for Wednesday and Thursday, as the short-wave presently
moving through southern bc digs into the central us. As this
happens, the upstream ridge is forecast to amplify along 130w
providing a little better upper level support to the tightening
north northeast surface gradients.

Lighter winds forecast to return later Thursday and continue
Friday as the ridge moves overhead.

Extended discussion (Saturday through Tuesday)
Models in good agreement in dropping an upper trough out of
western canada and into the northern great basin on Saturday.

Impacts on Saturday will be minimal. There should be a little
cooling but daytime highs Saturday are still likely to come in
several degrees above normal. Models continue diverged going into
early next week with a fairly significant difference in impacts
depending on solution. ECMWF continues to dig the upper trough
southward into the central great basin Sunday while the GFS tracks
the trough much farther east into the central u.S. During this
same timeframe. ECMWF solution would bring another round of strong
northerly winds to most of the CWA while the GFS solution would
leave norcal under light gradients and lighter north winds. Either
way, daytime temperatures cool behind the trough with daytime
highs dropping to near normal on Sunday. Leaning towards a middle
of the road approach to the winds Sunday and have gone with
relatively light north winds. Continued northerly flow will bring
a little more cooling on Monday with daytime highs dropping to
slightly below normal. Upper ridge slides over the west coast next
Tuesday bringing a slight warm up.

Aviation
Vfr conditions the next 24 hours at TAF sites. Generally
northerly sustained winds 5 to 15 knots.

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.
