Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
the pressure gradient between subtropical high pressure over the eastern pacific ocean and low pressure over the west is supporting fresh to strong northwesterly breezes and rough seas. The overall pattern will remain fairly stable over the next week although the high pressure will meander closer to the coast at times, bringing periods of near gale force winds and very rough seas. The first push is expected mid-week, with another over the upcoming weekend.

Area Forecast Discussion...UPDATED National Weather Service San Francisco CA 859 PM PDT Sun Jun 9 2024

New UPDATE, MARINE

SYNOPSIS
Issued at 107 PM PDT Sun Jun 9 2024

Warmer temperatures are in store Monday-Wednesday before a return to seasonal averages late week.

UPDATE
Issued at 855 PM PDT Sun Jun 9 2024

The short term forecast is in really good shape, with just some cosmetic changes to the wind/wind gust and weather grids. A consensus of the latest high-resolution short term forecast seems matches the best with the latest observations across the East Bay and SF Peninsula wind wise. As we've seen over the past few nights, winds will accelerate through the rest of the evening into before easing through the pre-dawn hours on Monday across these locales. Peak gusts will average between 20 and 30 mph across the SF Peninsula to 30 to 40 mph across the East Bay Hills/Mountains.

Regarding the fog potential---dewpoint depressions will approach 1-2 degrees across the the marine zones to a few miles inland along the coastline. While the PBL may remain somewhat overturned and result in a bit more in the way of low stratus, the signals from some of the short-term guidance suggests that patchy to even areas of fog may transpire for areas along the San Francisco Peninsula (Pacific Side) down toward Half Moon Bay, Santa Cruz, Monterey Bay, and down to Point Sur. Mariners and motorists should be aware of limited visibility late tonight and into early Monday morning.

Otherwise, the most dominant weather headlines will be the above normal temperatures and hot conditions, especially on Tuesday.
The current Heat Advisory appears to be in good shape, though we'll need to keep an eye on Wednesday across parts of the area.

SHORT TERM
(This evening through Monday)
Issued at 107 PM PDT Sun Jun 9 2024

One more pleasant day before the heat returns.

A short wave trough axis at 500 mb is now directly above the Bay Area. This is evident in the convective clouds over the Sierra moving to the NE and the stratocumulus over the ocean moving the the S. Locally, satellite imagery that shows most clouds have cleared, with the exception of the SF Peninsula coastline. The Ft. Ord profiler is measuring the marine layer at 2,100 ft deep.
This is helping keep temperatures in the 60s along the coast and adjacent valleys. Inland areas are in the upper 70s, and will take advantage of the clear skies to get into the mid-80s later this afternoon. Onshore winds will also begin to increase as the higher surface temperature allows more downward momentum transfer.

The short wave trough will continue to amplify and become a cut- off low west of the Channel Islands by Monday morning. This will allow a high pressure ridge to move in north of the low. This ridge will warm the air mass through both normal subsidence and by interacting with the cut-off low to generate some weak offshore flow around 700 mb. This effect is most evident in the North Bay where a tongue of higher thickness values will spill over from Nevada. Monday is the first day of the heat spell, with temperatures expected to reach the high 80s and lower 90s inland.

LONG TERM
(Monday night through next Saturday)
Issued at 107 PM PDT Sun Jun 9 2024

Temperatures will cool off quite a bit Monday night, retreating back to near normal values in the 50s. This will be a theme of the event with high afternoon temperatures, but good relief overnight.
Unlike the worst heat waves, there will be an opportunity to open the windows after dinner.

Tuesday looks to be the hottest day and has most of our attention.
Mid to upper 90s are expected for inland areas, as well as low 100s in the northern portions of Sonoma and Napa counties, the southern Salinas valley and San Benito county, and more generally along the easternmost portions of counties bordering the Central Valley. Warm temperatures persist into Wednesday, but begin to drop by a few degrees, with high temps largely similar to those on Monday. Coastal areas throughout this event will remain relatively cool in the mid to upper 60s, perhaps touching the lower 70s on Tuesday as onshore flow helps maintain more comfortable temperatures. As it currently stands, models continue to show light onshore flow persisting at the surface.

With these warmer temperatures comes increased HeatRisk. While Monday and Wednesday see largely Minor HeatRisk for the majority of our area, Tuesday will have many inland locations achieving Moderate levels of HeatRisk while coastal areas remain in the Minor category.
This moderate category indicates a level of heat that affects most individuals sensitive to heat, such as those that are ill, elderly, very young, or without shelter or a means to cool themselves such as air conditioning. As we draw nearer to this event, keep in mind that even if only Minor HeatRisk is indicated, that heat related illness and impacts can affect anyone, especially when heat is prolonged.
Its never a bad idea to make sure you are staying adequately hydrated during times of warmer temperatures, taking breaks in the shade if working outdoors, and to check in on loved ones who perhaps fall into the demographics of those sensitive to heat. Additionally, if planning to visit the coast or a body of water to cool off, make sure you wear a life jacket, swim near a lifeguard, and be aware of the risks of cold water shock.

By Thursday, high temperatures decrease and begin to cool off as troughing resumes and the cutoff low rejoins upper level flow and lifts out to our east. Sweet relief.

AVIATION
(00Z TAFS)
Issued at 436 PM PDT Sun Jun 9 2024

Moderate-high confidence in IFR/MVFR stratus impacting all terminals overnight with the exception of LVK and SJC. Winds will remain onshore through the TAF period. Widespread VFR to prevail by late morning tomorrow.

Vicinity of SFO...High confidence in MVFR stratus making an early return this evening, lower confidence in IFR developing. VFR to prevail by mid-to-late morning tomorrow. Winds will diminish overnight and briefly become offshore by mid-morning tomorrow before prevailing out of the west by tomorrow afternoon.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...High confidence in IFR stratus making an early return this evening. Westerly winds will prevail through the TAF period. VFR to prevail by late morning tomorrow.

MARINE
(Tonight through next Saturday)
Issued at 847 PM PDT Sun Jun 9 2024

The pressure gradient between subtropical high pressure over the Eastern Pacific Ocean and low pressure over the West is supporting fresh to strong northwesterly breezes and rough seas.
The overall pattern will remain fairly stable over the next week although the high pressure will meander closer to the coast at times, bringing periods of near gale force winds and very rough seas. The first push is expected mid-week, with another over the upcoming weekend.
