New SYNOPSIS, SHORT TERM, LONG TERM
SYNOPSIS
Issued at 1254 PM PDT Sun Jun 2 2024
Cooler temperatures hang on through Monday with breezy daytime winds and marine layer stratus overnight. Tuesday sees a dramatic warmup with a Heat Advisory in effect for the inland areas through Thursday. Temperatures will moderate towards the latter part of the week.
SHORT TERM
(This evening through Monday)
Issued at 1254 PM PDT Sun Jun 2 2024
Coastal stratus lingers over the western San Mateo Peninsula, with some cloud cover slipping through the San Bruno Gap, and in the southern Monterey Bay region. Expect the remaining cloud cover over the SF Bay region to dissipate through the rest of the afternoon and brief, if any, clearing for the coastal regions. Stratus returns inland tonight with the potential for gloomy skies through Monday, as the fringes of a cold front that impacts the Pacific Northwest come through the region. High resolution model output is showing some chance (10-20% PoP) for showers in the Sonoma coastal ranges, and coastal drizzle elsewhere, but accumulations are expected to remain very light, up to a few hundredths of an inch at most.
Northwest winds are picking up around the region and gusts will top out at 20 to 30 miles per hour across the gaps and passes. These winds are expected to diminish tonight before picking up again on Monday. Today's highs will be in the upper 50s to lower 60s along the Pacific coast, the mid 60s to lower 70s in the Bayshore, and generally in the upper 70s to lower 80s across the inland valleys.
The North Bay and southern Monterey County valleys will see highs rising into the mid to upper 80s. Low temperatures tonight will hover in the mid 50s to lower 60s, and Monday's highs should be similar to today's, except in the North Bay where the frontal influence will drop high temperatures to the upper 70s to around 80.
LONG TERM
(Monday night through next Saturday)
Issued at 1254 PM PDT Sun Jun 2 2024
Tuesday sees a pattern change as a subtropical high building in the eastern Pacific comes into the region, warming temperatures to well above the seasonal averages. A Heat Advisory is in effect for Tuesday through Thursday for the interior North Bay and East Bay, and Wednesday through Thursday for the South Bay and interior mountains of the Central Coast, where high temperatures rise into the 90s to the lower 100s and lows hover in the low to mid 60s, perhaps around 70 in the warmest locations. There's still a fair bit of uncertainty in how the warmth will translate to the coast, in particular how the marine layer and onshore winds will impact coastal temperatures. The current forecast calls for temperatures in the upper 70s to lower 80s along the Bayshore and the mid 60s to lower 70s along the Pacific coast.
Moderate HeatRisk is expected for the inland North Bay, the East and South Bays, and the inland Central Coast through Thursday, meaning that there's a moderate risk of heat-related illnesses for sensitive populations (children, the elderly, pregnant women, those with certain medical conditions, or anyone working outside without cooling or hydration). In addition, we're also starting to see major HeatRisk in some areas of the North Bay valleys and far eastern Contra Costa county on Tuesday, corresponding to a major risk of heat-related illnesses to anyone without effective cooling, adequate hydration, or both. Here are 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.
A gradual cooling trend is expected to begin later in the week as the high starts to crawl towards the east, with the large scale pattern hinting at a possible southerly wind reversal. By the upcoming weekend, high temperatures are expected to moderate to the low to mid 80s for the inland valleys and the upper 50s to mid 60s closer to the coast.

IFR to MVFR conditions prevail at locations near the coast but are expected to improve by late morning giving way to VFR conditions. Westerly winds will increase late morning and continue into the early evening hours before diminishing. These stronger winds are expected to last well into the evening hours as the SFO- SAC gradient is forecast to hover around the 4.0 mb range. As winds ease slightly into the late night, LLWS is likely to develop at a select few terminals as upper level winds remain elevated. Stratus will return to most San Francisco Bay area terminals the the late night of Sunday to early morning of Monday, bringing MVFR/IFR CIGs .
There remains some uncertainty as to whether CIGs will lower or lift. With troughing exiting the region, and the periphery of ridging beginning CIG level is low confidence for late Sunday/early Monday.
Vicinity of SFO...Currently IFR, though expected to improve to VFR by early afternoon. Winds will steadily increase into the afternoon today to become strong and gusting above 35 knots. Strong winds last beyond sunset, though gusts begin to diminish towards midnight.
Stratus makes a return in the evening bringing IFR CIGs .
SFO Bridge Approach...VFR currently. Otherwise, similar to SFO.
Monterey Bay Terminals...IFR to MVFR conditions persist through the morning. Clearing to VFR is expected to be late into the afternoon and only for a few hours. Winds will increase out of the west in the afternoon to become breezy, and will likely usher in the return of stratus and associated IFR CIGs in the early evening. IFR lasts well into Monday morning and then begin to lift to MVFR around KSNS.
MARINE
(Today through Friday)
Issued at 821 AM PDT Sun Jun 2 2024
Winds at this hour are fresh to strong, with gales having subsided. Expect northwesterly winds to gradually diminish through the day today to become fresh to moderate. As winds ease, wind waves will decrease, and significant wave heights will gradually lessen late tonight and into Monday, becoming 7 to 9 feet generally.
