New AVIATION, MARINE

SYNOPSIS
Issued at 233 AM PST Sat Dec 2 2023

Cool, unsettled weather for the next few days followed by a warming trend into early next week. An approaching trough of low pressure towards the middle of the upcoming week will bring the return of unsettled weather.

SHORT TERM
(This evening through Sunday)
Issued at 110 PM PST Sat Dec 2 2023

KMUX radar continues to pick up widely scattered showers moving through the Bay Area (Monterey/San Benito still dry) this afternoon. Automated sensors have tipped a few hundredths since this morning. Despite scattered showers moving through the region there are pockets of sunshine peeking through the clouds.
Temperatures this afternoon will top out in the 50s and 60s, which is close to or below seasonal averages for early December.

Tonight through Sunday...the shower activity that made it as far south as Santa Cruz will begin to move northward this evening/tonight as high pressure aloft begins to slowly build in from the SW. Sunday will be split with shower chances: south of the Golden Gate will be dry while the North Bay could still see some showers through Sunday evening.

LONG TERM
(Sunday night through next Friday)
Issued at 150 PM PST Sat Dec 2 2023

All shower activity tapers off Sunday night into Monday as the upper level ridge strengthens over the region. Drier weather warmer temperatures to start the work week. In fact, pretty solid warm up by Tuesday with highs reaching the upper 60s to mid 70s, which is above normal for this time of year.

The warm and dry weather quickly comes to an end Tuesday night into Wednesday as a cold front approaches from the NW. This front will bring precip back into the forecast by early Wednesday. Rain will initially be possible over the North Bay on Wednesday morning before spreading south through the day. Wet weather will linger into Friday. Once again, not a big rain maker but 0.01"-0.25" most areas and 0.25"-1.0" North Bay. Unlike the last system the late week system will usher in a much colder airmass. Snow levels will actually drop Thursday night into Friday to near 4k feet.
Therefore, cannot rule out some wet snow over the highest peaks.
At this point, not expecting any accumulation, but some snow is possible.

The bigger concerns with the colder airmass will be the overnight lows Friday night and beyond. The coast and bays will be spared from the real cold temperatures, but interior valleys will be in the low to mid 30s with a few isolated spots in the upper 20s.

AVIATION
(00Z TAFS)
Issued at 431 PM PST Sat Dec 2 2023

Currently seeing light rain showers move their way across the Bay Area. The bulk of the shower activity has passed with chances beginning to taper off. All terminals will experience MVFR ceilings with STS being the only terminal to see IFR/LIFR. With the exception of STS, there are no forecast visibility reductions to the terminals; however, if a shower were to pass over the terminal, visibilities may be briefly reduced.

Vicinity of SFO... Currently MVFR with showers approaching from the west. Shower activity will begin to taper off within the next several hours. There are no forecast reductions to visibility; however, if a shower were to pass over the terminal, visibilities may be briefly reduced. MVFR ceilings will come and go throughout the TAF period, with lower confidence in the 17Z-18Z window.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently VFR at both TAF sites; however, this will quickly transition to MVFR as the cloud shield from the PNW system moves southward. MRY will see their MVFR ceiling after 3Z and retain it until about 19Z and SNS will see their MVFR ceiling after 2Z and retain it until about 18Z. The terminals will experience E/SE winds during this time. After clearing, both terminals should stay VFR the rest of the TAF period and experience breezy onshore flow.

MARINE
(Tonight through next Thursday)
Issued at 431 PM PST Sat Dec 2 2023

Westerly winds will remain gentle to moderate today and will continue through the weekend, along with chances of rain in the northern waters. Northwest swell will continue until Monday, creating elevated seas of 8 to 10 feet and will pose hazardous to small craft vessels in the outer waters. Another northwest swell will follow, creating larger waves with 16-21 second periods through the upcoming week.

MTR WATCHES/WARNINGS/ADVISORIES
CA...None.
PZ...Small Craft Advisory until 9 PM PST Sunday for Pt Arena to Pt Reyes 10-60 NM.
