Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
the strong eastern pacific subtropical high pressure system is currently 1028 mb and will continue to strengthen and move closer to the coast through the day. The gradient between this system and a low pressure trough over california will support strong nnw winds with gale force gusts across the majority of the exposed marine zones. Buoys are reporting significant wave heights of 10 feet. Long period nw swell will arrive tonight, building combined seas to 15 feet.

New AVIATION, MARINE

SYNOPSIS
Issued at 155 AM PDT Sun Nov 3 2024

Elevated fire weather concerns will persist into next week due to dry conditions and offshore winds.

SHORT TERM
(Today and tonight)
Issued at 155 AM PDT Sun Nov 3 2024

Today would be a great day to put away your outdoor Halloween decorations if you haven't already before the wind does it for you.
High pressure building into the Pacific Northwest and an upper-level trough digging into the Great Basin will dominate the pattern through tomorrow morning. The pressure gradient will tighten throughout the day, supporting strong winds largely on the order of 20-30 mph with gusts up to 50 mph in the higher elevations. The surface pressure gradient will support northerly (drying) winds in bayside, coastal, and valley locations while the 925 mb pressure gradient will support northeasterly/offshore winds in the higher elevations. Fortunately the area is just coming off widespread beneficial rainfall which will at least initially dampen fire weather concerns. However, due to their lack of a westerly component (no Pacific Ocean moisture) and the region that they come from (land), northerly winds will lead to drying and northeasterly/offshore winds will lead to compressional warming.
Just how much drying takes place in the next two days will be crucial for fire weather concerns going into Tuesday night.

LONG TERM
(Monday through Saturday)
Issued at 155 AM PDT Sun Nov 3 2024

The pause button is hit on elevated fire weather concerns Monday afternoon as the upper-level trough progresses off to the east, allowing the pressure gradient to relax and winds to diminish.
Elevated fire weather concerns return Tuesday night as global ensemble clusters are in agreement of high pressure building into the Pacific Northwest and a reinforcing trough digging into the Desert Southwest. High pressure to the north of low pressure to the south forms something called a Rex block, this pattern in and of itself comes with a lot of uncertainty as the onset and decay is not handled well by numerical weather models. As for this specific setup, uncertainty lies in the location and strength of the upper- level trough. It is likely that the upper-level trough will become a cutoff low, further increasing uncertainty as it would lack jet stream support and thus be able to linger. All this to say, elevated fire weather concerns are expected Tuesday night through Thursday morning due to dry conditions and offshore winds. This event will be heavily contingent upon how fuels respond to the winds preceding it and how strong the offshore pressure gradient gets.

AVIATION
(12Z TAFS)
Issued at 348 AM PST Sun Nov 3 2024

With cold air aloft supporting a well mixed atmosphere, VFR conditions are expected to persist through the TAF period, although a few mid-level clouds are possible before 18Z. Building high pressure off the coast will generate strong NW winds starting late morning.

Vicinity of SFO...VFR conditions now look to continue through the TAF period, with only a 5% chance of developing an MVFR ceiling briefly this morning. Otherwise clear skies will dominate, with strong NW wind in the afternoon.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR conditions expected through the TAF period with only a 10% chance of MVFR conditions this morning.
Strong onshore winds will develop this afternoon before easing overnight.

MARINE
(Today through Friday)
Issued at 348 AM PST Sun Nov 3 2024

The strong Eastern Pacific subtropical high pressure system is currently 1028 mb and will continue to strengthen and move closer to the coast through the day. The gradient between this system and a low pressure trough over California will support strong NNW winds with gale force gusts across the majority of the exposed marine zones. Buoys are reporting significant wave heights of 10 feet. Long period NW swell will arrive tonight, building combined seas to 15 feet.

FIRE WEATHER
Issued at 115 PM PDT Sat Nov 2 2024

Slightly better outlook this morning for the first of two offshore winds events progged for this upcoming week. Most areas received beneficial rainfall overnight that will dampen fire weather concerns slightly going into Sunday. However, vigilance is still encouraged as we are early in the season and live fuels have not accumulated much moisture thus far, so any potential benefit from last night could be erased relatively easily as the offshore winds continue into Monday morning. Current live fuel moisture forecast still advertises ERCs around or above the 60th percentile by midweek.
Therefore, while the early week offshore event holds a slightly more positive outlook, the midweek system could be more concerning. By that time, live fuels would have had plenty of time to dry out sufficiently, and there is considerable uncertainty regarding the evolution of the pattern during the peak wind period Wednesday. The RH forecast for Tuesday-Thursday will potentially need to be nudged lower after losing some evapotranspiration potential to the offshore winds earlier in the week that I suspect some models may be holding on to. Will need to wait and see how fuels respond early to the winds through Sunday, and will likely have a much clearer picture of the midweek system by Monday.
