Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries...
northwest winds are increasing as a band of showers that continues to move through the waters. Winds will reduce into the late night as rain chances exit. Elevated seas between 12-15 feet will persist through late week as a series of long period northwest swells propagate through the waters, resulting in hazardous conditions for small crafts.

New AVIATION, MARINE

SYNOPSIS
Issued at 1233 PM PST Thu Dec 7 2023

Rain comes to an end by late in the day. Cold overnight temperatures are expected for the next couple of nights, especially across the interior. Warming trend expected early next week.

SHORT TERM
(This evening through Friday)
Issued at 1233 PM PST Thu Dec 7 2023

Light to moderate rain is moving across the North Bay as of this writing, will sweep through the Bay Area between 12 PM - 2 PM, and then arrive along the Central Coast early/mid afternoon. Rainfall amounts will be light with the North Bay coastal ranges seeing the highest totals, up to 0.25". Around 0.10" is expected in the North Bay Valleys and across the City, then amounts tapper downward as one heads south.

A colder air mass will then settle into the region overnight. Lows are expected to cool into the lower 30s in the wind-sheltered interior. Elsewhere, expecting temperatures to lower into the mid 30s to lower 40s. A Frost Advisory has been issued for the North Bay Valleys, Southern Salinas Valley, southern portions of Monterey/San Benito counties for tonight.

Tomorrow, high temperatures will struggle to warm above the upper 50s (lower 40s in the peaks).

LONG TERM
(Friday night through next Wednesday)
Issued at 1233 PM PST Thu Dec 7 2023

Saturday morning will be the coldest with interior areas dropping into the mid 20s to lower 30s. For this, we have a Freeze Watch in effect for the aforementioned zones. A gradual warming trend will resume heading into next week.

AVIATION
(00Z TAFS)
Issued at 621 PM PST Thu Dec 7 2023

A cold front located across the north Central Coast over to Santa Clara County continues moving southeastward. Showers along the cold front and a few lingering showers in the wake of the cold front are forecast to diminish across our forecast area tonight.
Conditions are currently MVFR-VFR except KCVH briefly reported IFR ceiling and visibility.

Patchy fog, possibly dense fog, /LIFR-IFR/ may develop tonight and Friday morning due to moistened boundary layer air, light winds, clearing, long December night-time radiative cooling to space. Recent statistical guidance e.g. for KSTS is weighted toward fog tonight. The 00z Oakland upper air sounding showed the highest distribution of water vapor at and below 8500 feet and it was drier above 8500 feet. The synoptic pattern transitions from mid to upper level troughing this evening to ridging, including lower to mid level thermal ridging Saturday. Surface high pressure builds over far northern California to the Great Basin resulting in offshore winds Saturday through Saturday night.

Vicinity of SFO...VFR, west wind 5 to 10 knots this evening.
Statistical guidance wind forecasts may be a bit overdone, if the surface winds do diminish to light overnight then fog /LIFR/IFR/ is more likely to develop late tonight and Friday morning; not indicated in current 00z TAF, though will monitor satellite and surface observations and amend if needed. Otherwise mixing winds resulting in VFR for KSFO Saturday, best chances VFR late morning and afternoon.

SFO Bridge Approach...Similar to SFO

Monterey Bay Terminals...It's MVFR-VFR with occasional showers; the cold front continues to move southeastward across the north Central Coast. Boundary layer air moistened from rain may result in patchy low clouds and fog /LIFR-IFR/ overnight and Friday morning; not indicated in current 00z TAFs, though will monitor satellite and surface observations and amend if needed. Mixing winds Saturday resulting in VFR.

MARINE
(Tonight through next Tuesday)
Issued at 350 PM PST Thu Dec 7 2023

Northwest winds are increasing as a band of showers that continues to move through the waters. Winds will reduce into the late night as rain chances exit. Elevated seas between 12-15 feet will persist through late week as a series of long period northwest swells propagate through the waters, resulting in hazardous conditions for small crafts.

MTR WATCHES/WARNINGS/ADVISORIES
CA...Freeze Warning from midnight tonight to 9 AM PST Friday for CAZ506-516-518.

Freeze Watch from late Friday night through Saturday morning for CAZ506-516-518.
