Area Forecast Discussion National Weather Service San Francisco Bay Area 1036 AM PDT Thu Jul 29 2021

SYNOPSIS. Seasonably warm weather pattern continues inland through Friday with high pressure over the region. A shallow marine layer will persist along the coast keeping temperatures seasonably mild near the coast and bays. A modest cooling trend starts this weekend for inland areas as onshore winds strengthen and the marine layer deepens along the coast.

DISCUSSION. as of 9:28 AM PDT Thursday . Have put the kmux radar into precip mode to better scan some of the high based returns well offshore. Vandenberg and Oakland soundings suggest moisture is above 500 mb so not expecting any convection and it looks to stay offshore as well. Marine layer around 1500 feet deep along the coast with low clouds retreating quickly this morning revealing some of the mid/high level clouds and instability passing south to north. Of note on morning visible satellite is the activity over the southern Sierra that is already bubbling and will likely start earlier than normal across the central/northern Sierra this afternoon. For the Bay Area expect another seasonably hot day inland with widespread 90s and even some lower 100s. Fuels of course remain near or at record dry levels inland/hill locations and yesterdays Pinnacles fire showed how rapidly fires can grow even during routine weather days given the current drought stressed fuels. Fun side note is many of the record highs for today date back to 1977 and preceded that years lightning event that stared the Marble Cone fire locally and many other fires across NorCal.

No big changes of note for Friday. Do expect some inland cooling by this weekend as the marine layer deepens and onshore winds strengthen in response to approaching West Coast trough that will nudge the main ridge farther eastward while fairly significant monsoonal moisture will sneak northward into NV/ID/OR. Long range trends remain seasonably warm and dry into early August for the Bay Area.

AVIATION. as of 10:45 AM PDT Thursday . For the 18z TAFs. Typical midsummer pattern in effect with marine stratus along the coast and monsoonal air aloft. Generally, expect to see VFR today, with FEW- SCT at 15000-20000 feet through the afternoon. Winds generally light and terrain driven in the morning, becoming locally breezy onshore through the coastal gaps in the afternoon. For tonight, a compressed marine layer will bring similar patchy VLIFR- IFR level marine stratus cigs to coastally influenced terminals and lowering mid to high level FEW-SCT 10000-15000 ft cigs elsewhere. Similar pattern tomorrow.

Vicinity of KSFO . VFR through the TAF period. Winds remain mild until afternoon with peak winds from the Northwest around 15-20 kts. These winds look to last through that evening but back off into Thursday night. For tonight, patchy stratus deck returns with borderline MVFR/IFR SCT/BKN deck into mid morning Friday.

KSFO Bridge Approach . Similar to KSFO.

Monterey Bay . Winds remain weak and variable through the morning, before becoming onshore and slightly breezy in the afternoon. Winds weaken and stratus returns in the late evening and early night leading to IFR around the Monterey Bay overnight.

MARINE. as of 10:32 AM PDT Thursday . Generally light to locally moderate gusty northwest winds across the northern outer waters. Breezy to gusty west winds each afternoon and evening across the San Francisco Bay north of the Bay Bridge otherwise light northwest winds through Monday. A moderate period southerly swell will persist in the waters.
