Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Breezy northwest winds will continue through the overnight hours as high pressure builds inland. The strongest winds are expected along the big sur coast south of point sur. Winds will continue to increase Tuesday across the waters, with gale force gusts developing along the big sur coast. Strengthening winds will generate steep northwest waves resulting in hazardous seas conditions, particularly for smaller vessels. Light southerly swell will continue along with mainly wind driven northwest waves.

Area Forecast Discussion National Weather Service San Francisco Bay Area 915 PM PDT Mon Jun 14 2021
SYNOPSIS. Pleasant conditions for the remainder of Monday. High pressure over the desert southwest expands and moves over Southern California starting a warming trend on Tuesday. Robust heating is forecast Wednesday through Friday with peak heating on Thursday, prompting a Heat Advisory and Excessive Heat Warnings to be issued. Onshore flow will help limit impacts along the coastline and within the San Francisco Bay. The areas at most risk for heat impacts will likely be farther interior locations. Cooling expected over the weekend.
DISCUSSION. as of 08:55 PM PDT Monday . Satellite currently shows a stratus deck over the water and along parts of the central and North Bay coast line. Temperatures were seasonal this evening, with some areas along the coast seeing a few degrees below normal. That is still on track to change this week. The heat advisory and heat warnings are consistent with the newest data. The only change made is that the heat warning and advisory for Friday is extended into the evening hours, now lasting until 9 pm PDT. This will account for Friday's warmer temperatures as well. Winds will remain light overall, making fire weather less of a concern this week.
Models have been showing the delta breeze kicking in Thursday evening, which will bring cooler over night temperatures to the coast and inland locations for Friday morning. Temperatures will still get hot Friday, but we begin a cooling trend. Albeit slow, the cooling trend will bring temperatures back to normal by early next week. Normal is still fairly warm for the interior as we are moving back into summer patters.
PREV DISCUSSION. as of 02:05 PM PDT Monday . Thinly veiled stratus drapes over the ocean and down the California coastline, with clearer, sunny skies over the land other light cumulus around the highest peaks. Temperatures are in the low 70s, expecting to peak this afternoon in locations farther inland in the upper 70s/low 80s. Moderate northwest winds are breezy, but are expected to increase with localized gustier conditions along the coast and through coastal gaps.
From a big picture standpoint, there is a broad long wave trough over the Pacific Northwest with a high pressure ridge over the desert southwest centered just east of the Four Corners. Between these two features has been consistent southwest flow aloft, keeping conditions pleasant. Starting Tuesday, the trough will lift northward toward Canada, with the ridge expanding and strengthening back toward California.
ECMWF, GFS and ensemble models have the ridge growing to just under 600 dam at 500 millibars by Wednesday morning. These models depict at 850 millibars, temperatures slowly climbing to between 26 and 29 degrees Celsius by Thursday over much inland locations around the Bay Area and down the Central Coast. With winds being mostly limited to the coastline, all of this translates to a hot and dry airmass approaching the Bay Area increasing Tuesday, with hottest temperatures on Thursday and not beginning to cool down until the weekend. Therefore, a Heat Advisory has been issued for the North Bay Mountains and Valleys, East Bay Hills and Valleys, the Santa Clara Valley, the Santa Cruz Mountains, the Mountains of San Benito, the Santa Lucia Mountains and Southern Monterey County. For Thursday, the hottest day of the week, the North Bay Mountains, East Bay Hills and Valleys, the Mountains of San Benito, the Santa Lucia Mountains and Southern Monterey County get upgraded to an Excessive Heat Warning as temperatures in inland areas will likely climb toward and exceeding 100 degrees.
The good news for coastlines is that models are insinuating consistent onshore flow through the week, helping to tamper down temperatures there. What complicates the forecast is that winds on Wednesday look to be at their strongest, which if they materialize and move farther inland can inhibit the strength of the heat on the first day which is why it was a widespread advisory for the first day and not a warning at this time.
Temperatures Friday will still be hot but begin to go down. Any robust cooling is likely not expected until the weekend. However, that becomes a relative term now that June in the Bay Area is in full swing. Conditions leading into next week will be warm and dry.
AVIATION. as of 5:30 PM PDT Monday . For the 00z TAFs. VFR across terminals. Stratus over the coastal waters is observed on satellite banking up against most of the coastline, with the exception of Monterey Bay. Otherwise, clear skies over the terminals, as a drier airmass builds in from the desert southwest. Drier air and a stronger northerly gradient will result in less stratus over terminals this evening into Tuesday morning. Some low clouds may fill in along the bay coastlines but low confidence in Cigs at this point. Calm/light winds will also result in some LLWS at some of the North Bay terminals as a mid- level low departs the region from 7Z to 12Z. Widespread VFR will reign supreme across the region by tomorrow morning through the end of the TAF period as the surface high becomes the dominant synoptic feature. Breezy conditions return in the afternoon along the coast and especially near coastal gaps.
Vicinity of KSFO . Mostly clear skies with some gusty WNW winds (near 30 kt). Winds remain gusty through mid-evening and subside overnight. A compressed marine layer, drier air filtering into the area and hi-res model solutions suggest Cigs are less likely to form around the terminal overnight. Sct low clouds are included in the TAf with tempo Cig in the early morning but may be removed if drying trend continues. Gusty onshore winds (30-35 kt) return Tuesday afternoon near the terminal, with VFR through the end of the TAF period.
SFO Bridge Approach . Similar to KSFO.
Monterey Bay Terminals . Satellite picture reveals clear skies over area terminals and the bay, though low clouds linger over the peninsula. Breezy onshore winds will weaken overnight. While some FEW/SCT low clouds are possible for the region tonight, marine stratus return will be limited to the immediate coast. TEMPO MVFR Cig included at KMRY but may be removed if drying trend continues. Expect widespread VFR tomorrow morning and through the end of the TAF period with some breezy afternoon winds.
MARINE. as of 02:52 PM PDT Monday . Northwest winds are expected to continue to increase across the waters today and tonight as high pressure builds farther inland. The strongest winds are expected along the Big Sur coast south of Point Sur, increasing more so on Tuesday when gale force gusts may develop. Increasing winds will generate steep northwest waves resulting in hazardous seas conditions, particularly for smaller vessels. Light southerly swell will continue along with mainly wind driven northwest waves.
