Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
strong northerly winds continue through the midweek, with gale-force gusts expected over the outer waters and near the big sur coast. Towards the early Thursday morning, winds slowly ease to become fresh to moderate. However, as a result of strong winds in the early portion of the week, significant wave heights will build to heights of 15 to 16 feet over the outer waters by mid-week. SEa conditions will be hazardous Tuesday and Wednesday with gale warnings issued for portions of the coastal waters. By the late week into the weekend, winds ease to become gentle, significant wave heights gradually diminish to 5 to 7 feet, and dry weather continues as high pressure dominates.

New SYNOPSIS, SHORT TERM, LONG TERM
SYNOPSIS
Issued at 116 PM PDT Tue May 7 2024
A warming trend begins Wednesday as offshore winds develop, with a Wind Advisory for the interior North Bay on Wednesday morning.
Warmest temperatures are expected Thursday and Friday before a slight cooldown into the early part of next week.
SHORT TERM
(This evening through Wednesday)
Issued at 116 PM PDT Tue May 7 2024
Clear skies throughout the day today with little to no stratus development this evening and overnight. High temperatures today range from the mid 50s to low 60s on the coast, the upper 60s to lower 70s on the Bayshore, and into the mid to upper 70s in the interior valleys. Breezy northwest winds will develop this afternoon, gusting up to 20 to 25 miles per hour in the ridgelines and passes. Overnight lows will generally range from the mid 40s to the lower 50s, with some of the most interior regions seeing lows in the lower 40s.
A warming trend begins Wednesday, with a ridge building over the northeast Pacific expanding into the Pacific Northwest, interacting with a piece of an upper level low over the Northern Plains that regresses over the Rocky Mountains and breaks off into a weak cut- off low over the Great Basin. The end result is that offshore flow will start to develop through Wednesday, with the higher elevations and North Bay being the first to experience the wind shift. A Wind Advisory is now in effect for the North Bay interior mountains and valleys from 1 AM to 11 AM on Wednesday, for sustained winds of 20 to 30 miles per hour and gusts up to 45 miles per hour in the higher elevations. The rest of the region should see wind gusts topping out around 20 to 25 miles per hour. High temperatures on Wednesday range from the low to mid 60s along the coast to the upper 70s to lower 80s in the interior valleys.
Despite the breezy offshore winds and the warming trend, very little fire danger is expected, with moist fuels mitigating fire weather concerns throughout the region.
LONG TERM
(Wednesday night through next Monday)
Issued at 116 PM PDT Tue May 7 2024
The warming trend continues into the early part of the weekend, with Thursday and Friday expected to be the warmest days of the event.
High temperatures range from the upper 60s to lower 70s near the coast, to the upper 80s to lower 90s inland. With northeasterly offshore flow continuing through Thursday, and with prior pattern recognition of warmer temperatures in downslope areas as a result, have increased temperatures on Thursday from the previous forecast.
The seasonably warm temperatures are causing a minor to moderate HeatRisk, meaning that a low to moderate risk for heat related illnesses exists for vulnerable populations (children, the elderly, pregnant women, or those without adequate shelter or cooling), with moderate HeatRisk values concentrated in the interior regions of the North, East, and South Bays. For some context: downtown San Francisco, which sees highs around the mid 60s this time of year, is expected to top out at 81; Santa Rosa, where the seasonal average high is in the mid 70s, is facing a high temperature of 89; and Salinas is forecast to reach a high of 80 versus a seasonal average high of 68.
With the significant warm up expected for the rest of the week, here's a reminder of some heat safety tips:
* Stay hydrated and drink plenty of fluids.
* Wear lightweight, light-colored clothing.
* Reduce time spent outdoors or stay in the shade.
* Never leave people or pets unattended in vehicles.
* Use sunscreen if going to the coast or the pool.
The heat should start to abate on Sunday as onshore flow returns to the region, but temperatures warmer than the seasonal averages are expected to continue for the foreseeable future, with CPC products stating that temperatures above seasonal averages continue into the third week of May.
AVIATION
(18Z TAFS)
Issued at 1053 AM PDT Tue May 7 2024
VFR through the TAF period with breezy northwest winds continuing into the evening with light to moderate west to northwest winds overnight. Heading into tomorrow, gusty north to northwest winds return as upper level ridging and surface high pressure builds. Wind shear is expected at STS, APC, OAK, SFO, and LVK overnight. Moderate to high confidence that VFR will prevail at all stations overnight.
HRRR indicates some cloud cover in the Monterey Bay tomorrow morning but coverage should remain few to scattered.
Vicinity of SFO...VFR through the TAF period. Breezy to gusty west to northwest winds continue into the evening with moderate westerly winds overnight. Gusty winds return by mid tomorrow morning with gusts up to 22 knots possible. A few ensemble members indicate that gusts between 25-27 knots are possible tomorrow so will keep an eye on and adjust gusts as needed.
SFO Bridge Approach...Similar to SFO.
Monterey Bay Terminals...VFR through the TAF period. Moderate northwest winds becoming gusty during the afternoon at SNS. Winds weaken to light to moderate overnight with winds becoming more variable at MRY. HRRR guidance shows some cloud cover in Monterey Bay but confidence is low that a ceiling will develop as upper level conditions will be drier and the marine layer will be fairly shallow as high pressure builds. Any cloud coverage that does develop at MRY will be few to scattered.
