PZZ500 859 Am Pdt Fri Jun 7 2024
Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
areas of fog and drizzle will cause reduced visibility through the morning across Monterey bay and along the big sur coast. Winds and seas will remain hazardous for areas along and north of the greater farallones through Friday afternoon where small craft advisories remain in effect. Elsewhere, winds and seas are forecast to subside below 20 knots and 10 feet, respectively. This will be relatively short lived as 20-25 knot winds increase during the pre-dawn hours on Sunday. Seas will respond later Sunday morning and into the afternoon, likely necessitating additional marine headlines.

SYNOPSIS
Issued at 336 AM PDT Fri Jun 7 2024

Cooling continues through the weekend, with temperatures largely near seasonal averages. Warming returns early next week as ridging redevelops, though not expecting temperatures to reach as high as they did the last few days.

SHORT TERM
(Today and tonight)
Issued at 336 AM PDT Fri Jun 7 2024

A look at nighttime satellite this morning shows stratus trickling down the Salinas valley, and attempting to reach up into the SF Bay Area. An "otter eddy" can be seen swirling about the Monterey Bay as stratus continues to feed in. Elsewhere, skies are clear and temperatures comfortable in the mid 50s for most locations. Speaking of more comfortable temperatures, highs today will largely be in the low to mid 80s for inland regions, mid to upper 70s for the SF bay region, and closer to the low 60s for the coastline. This cooldown comes as a upper level shortwave trough moves through the region today bringing relief to many regions.
Temperatures will largely be close to seasonal averages, perhaps just 2-3 degrees above normal for far southern Monterey county and the northern extremes of Napa and Sonoma counties.

The cooling trend continues into the weekend as models show good agreement in an upper level trough developing Saturday. This will also usher in mid to high level clouds that will dot the sky, with coastal stratus becoming more widespread. The extent of stratus along the coastline will be helpful in keeping temperatures on the cooler side through the early part of the day, around 5-10 degrees lower than normal in some spots. Along the coastline, high temps will be in the upper 50s to low 60s. Further inland on Saturday and Sunday, highs will generally be in the low 80s, with a few particular warm spots closest to the Central Valley seeing the upper 80s. This upper level trough will also help create breezier conditions in the afternoons, largely in the Salinas valley and the SF Bay counties bordering the delta region. Wind gusts towards the 20-25 mph mark in this favored areas are possible, but then ease into the nighttime.

LONG TERM
(Saturday through Thursday)
Issued at 336 AM PDT Fri Jun 7 2024

Starting Monday, the trough begins to be cut off, eventually forming a cut-off low. This transient low, without any good steering mechanism, lingers through the mid to late week to our southwest before exiting off to the east in the later week, lifting into our region as it does so. Despite this lingering feature, models indicate slight ridging developing into the early week which will help to warm temperatures once more. However, as it currently stands, the warmth will likely not be the the levels seen previously this week. Low to mid 90s for the inland regions Monday and Tuesday are forecast, with mid 60s to the lowest 70s at the coast. Tuesday currently appears to be the warmest day, with high temperatures generally about 10 degrees above normal for inland locations.
Wednesday, slight cooling returns with high temperatures receding by a few degrees. This cooling trend persists through the remainder of the week as the pesky low reconnects with the jet stream and lifts out to the east.

More zonal flow (west to east) develops over our region in the late week next week. Current CPC 6-10 and 8-14 day outlooks suggest near normal temperatures for our region.

AVIATION
(18Z TAFS)
Issued at 1041 AM PDT Fri Jun 7 2024

The coastal stratus is mixing out and most terminals have returned to VFR conditions. With high pressure aloft, the North Bay terminals have been slight visibility reductions in haze. A 500 mb ridge axis will gradually push through this evening before troughing begins to move in Saturday. This will allow the marine layer to compress slightly overnight and should bring ceilings lower. Otherwise moderate onshore winds will remain in place before drainage flow sets up in the valleys tonight.

Vicinity of SFO...Winds are currently from the NNE, but will soon shift to the standard 280 this afternoon. SFO is currently VFR, with model guidance suggesting a push of stratus through the Golden Gate this afternoon. This will likely bring MVFR CIGs to OAK by the late afternoon/early evening, but due to the wind direction and terrain shelter, SFO has a better chance of staying VFR with low clouds remaining to the N and E. SFO won't dodge the low clouds forever though as a deepening marine layer will very likely bring MVFR conditions to the terminal Saturday morning.

SFO Bridge Approach...The bridge approach is likely to stay clear this evening, even if SFO and OAK develop ceilings.

Monterey Bay Terminals...Morning ceilings are starting to clear and there is a 6 or 7 hour window of VFR conditions expected before they return. With a compressing marine layer, MRY has about a 50% chance of seeing LIFR conditions in the morning, with a 40% chance at SNS. There is also a decent chance for morning mist, and subsequent TAF updates may get more aggressive dropping the visibility. Otherwise SNS has been reporting some haze this morning, and that is expected to continue under high pressure.
Expected moderate W-NW winds through the TAF.

MARINE
(Today through Wednesday)
Issued at 1041 AM PDT Fri Jun 7 2024

Areas of fog and drizzle will cause reduced visibility through the morning across Monterey Bay and along the Big Sur Coast.
Winds and seas will remain hazardous for areas along and north of the Greater Farallones through Friday afternoon where Small Craft Advisories remain in effect. Elsewhere, winds and seas are forecast to subside below 20 knots and 10 feet, respectively. This will be relatively short lived as 20-25 knot winds increase during the pre-dawn hours on Sunday. Seas will respond later Sunday morning and into the afternoon, likely necessitating additional marine headlines.

MTR WATCHES/WARNINGS/ADVISORIES
