Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Gusty northwesterly winds will persist across the northern outer waters and along the coast north of point reyes into tonight as high pressure remains over the eastern pacific. Additionally, expect locally gusty winds to develop this afternoon around the coastal gaps, over the bays, and along the big sur coast south of point sur. These winds will generate steep fresh swell resulting in hazardous conditions over the waters, particularly for smaller vessels. Winds will diminish tonight as high pressure weakens and an upper low moves offshore of the pacific northwest. Expect northwesterly winds to re-strengthen later this week.

area forecast discussion

341 am pdt Tue jun 25 2019

Synopsis
Daytime temperatures cooling over the next few days with
highs on Thursday 10 or more degrees below normal. A slight chance
of showers northern shasta mountains Thursday... Otherwise dry.

A warming trend begins Friday with highs climbing to above normal
by next Sunday. Occasionally breezy winds through the delta and
over the higher terrain mainly next few days.

Discussion
Northern california currently under southwest flow aloft between
a high pressure ridge over the great basin and a unseasonably cool
low pressure system off the pacific northwest coast. Small
shortwave troughs rotating through this southwest flow bringing
scattered high cloudiness to the forecast area but for the most
part skies are fair. A moderate delta breeze continues but coastal
stratus is minimal so should not see much in the way of coastal
stratus coming into the valley this morning. Onshore flow and
cooling airmass will bring cooler temperatures today. Daytime
highs are expected to drop to around normal. Some areas will see
increased winds ahead of the low over the next few days
especially the delta and over higher sierra cascade elevations.

The upper low is forecast to move towards the oregon coast on
Wednesday bringing more cooling over the forecast area. Daytime
highs will drop to well below normal and marine layer is likely to
deepen. There may be some morning coast stratus intrusion into
the delta but any precipitation should remain north and west of
the forecast area.

By Thursday, the upper low begins moving into the pacific
northwest. Daytime highs should drop to the coolest of the week
and 10 to 15 degrees below normal. Although precipitation should
continue to remain mainly north of the forecast area, a few
showers may reach as far southward as the northern shasta county
mountains. A still deeper marine layer may bring morning coastal
stratus into the delta again during the morning hours. Models
are consistent in lifting the upper low to the northeast on
Friday. This should bring lighter winds and allow temperatures to
warm a few degrees over Thursday although daytime highs will
remain a few to several degrees below normal.

.Extended discussion (Saturday through Tuesday)
a gradual warming expected this weekend into early next week.

Troughing may remain near the west coast, but confidence is low
given latest deterministic and ensemble differences. Therefore,
temperatures might not be as warm as previously anticipated.

Forecast highs will remain below normal through Sunday, followed
by near normal temperatures early next week. By early next week,
look for valley highs in the 90s, and 60s to low 80s over the
mountains.

Aviation
Vfr conditions next 24 hours. Surface winds mostly less than 12
kts at TAF sites, except for gusts up to 20 kts northern terminals
after 21z Tuesday, and after 00z Wednesday south of ksac.

Southwest wind gusts 25-30 kts possible through the delta.

Sto watches warnings advisories
None.
