Area Forecast Discussion National Weather Service San Francisco Bay Area 459 PM PDT Thu Jul 29 2021

SYNOPSIS. Seasonably warm weather continues into Friday before a slight cooling trend arrives Saturday through early next week. High pressure rebuilds over Southern California by the middle of next week with more inland warming while the marine layer will persist along the coast.

DISCUSSION. as of 2:55 PM PDT Thursday . Skies are mostly sunny this afternoon while a few high clouds pass over the region. Along the coast the marine layer is hugging area beaches with a current depth around 1200-1500 feet. Meanwhile over the Sierra moisture is increasing with numerous showers and t-storms across the crest and streaming northward. The ocean sea surface temps (SST) have trended upward the last few days as coastal upwelling has eased with light northwest winds. Current SST readings around 60 degrees has left the coast feeling muggier than normal and mild overnight lows even within the marine boundary layer. Temps this afternoon still running pretty hot inland with widespread 90s and even some lower 100s for the hottest interior valleys.

For tonight expect the marine layer to only push locally into the bay and coastal valleys given the shallow depth though onshore gradients remain moderate around 2.5 mb.

For Friday, still not expecting much overall change as seasonably hot weather will continue inland with mild to warm conditions near the coast and bays. Monsoonal moisture will still be abundant across the Sierra and Nevada as well as points northward but not expected to impact the Bay Area/Central Coast.

An incoming trough will approach late Friday night into Saturday. This should lead to a deepening marine layer and stronger onshore winds by Saturday afternoon and ultimately some slight cooling inland as upper 80s/lower 90s become more common versus upper 90s to lower 100s. This trough will bring increasing southwest wind flow aloft helping to push any residual monsoon moisture well east of the Bay Area and more east of the crest. In addition a better mixing profile and stronger winds aloft should help to keep Dixie Fire smoke from draining down the valley and into the Bay Area.

Weak troughing off the coast into early next week should keep temps near to slightly below normal with persistent marine layer and onshore winds. Building high pressure over SoCal by middle to end of next week will bring renewed inland warming but in general a pretty seasonable pattern as we head into August. As noted this morning many of todays record highs date back to 1977 which preceded the late July/early August lightning of that summer. No record heat waves on the horizon and not seeing any signals for lightning events at this time in the mid/long range as monsoonal pushes look to stay to our east.

AVIATION. as of 05:00 PM PDT Thursday . For the 00z TAFs. The latest coastal profilers continue to pick up on a shallow 700-1000 ft marine layer over our coastal waters that is helping to sustain 10-15kt winds over our coastal terminals this afternoon, particularly along our gaps and passes. Monsoonal moisture also continues to travel aloft, bringing in FEW/SCT cigs at 15000-20000 ft that will be a recurring theme through the end of the TAF period. For tonight, will see a return of IFR/LIFR cigs at our coastal terminals and even some patchy VLIFR cigs along the coast. Given the westerly flow, cannot rule out some coastal stratus making it into some of the North Bay terminals, mainly around STS, so have included the possibility there as well. Cigs will be relatively low given the shallow marine layer interface, and will be persistent through the overnight before clearing out by 16-17Z tomorrow. A similar pattern can be expected through the day tomorrow as VFR returns to the surface and mid/high-level clouds continue to roll over the region.

Vicinity of KSFO . Mostly VFR through the TAF period. Winds this afternoon will peak to nnw 15-20 kts. These winds look to last through that evening but will gradually back off during the overnight. For tonight, patchy stratus deck returns with borderline MVFR/IFR SCT/BKN deck into mid-morning Friday. Increasing confidence in this cigs being observed within the vicinity, so have added a TEMPO group to account for some of those conditions as stratification builds along the Bay Shoreline. Stratus will then rapidly retreat after 16Z, with breezy conditions and mid/high-level clouds expected through the end of the TAF period.

KSFO Bridge Approach . Similar to KSFO.

Monterey Bay . Breeze winds this afternoon as the Marine layer compresses. Light, variable winds will then be the theme for the evening along with the return of IFR cigs at the terminals and even some LIFR/VLIFR cigs along the immediate coast. These conditions will fizzle our by mid-morning.

MARINE. as of 04:37 PM PDT Thursday . Predominately light winds today, with locally gusty winds in the outer waters north of Point Reyes. In addition, the afternoon seabreeze will bring gusty west to southwest winds from the Golden Gate gap towards Angel Island, San Pablo Bay, and the Carquinez Strait through at least the next couple of days. Otherwise, a moderate southerly swell will persist in the waters.
