.SHORT TERM...
Issued at 1211 PM PDT Fri Aug 7 2026
(This evening through Sunday night)

The warming trend will begin today and persist through the 
weekend as high pressure over the Desert Southwest builds 
westward. Thus, Heat Advisories remain in effect for all of the 
Interior Bay Area and Central Coast from 10 AM Saturday through 10
PM Sunday. The exception is the North Bay Valleys where we have 
temperatures forecast to be in the mid 80s to mid 90s. However, 
places such as Cloverdale is forecast to be the hottest and are 
expected to exceed 100 deg F. Temperatures under the Heat Advisory
are forecast to warm into the mid 90s and up to 105 deg F in the 
warmest interior locations where the most widespread moderate to 
isolated major HeatRisk are present. Overnight lows are also 
forecast to be warm in the mid 60s in the hills just above the 
marine influences to low 80s (especially in the higher 
elevations). Maximum temperatures closer to the coast are forecast
to be in the 60s to mid 70s thanks to the continued onshore flow 
and marine influences. Overnight lows near the coast are largely 
forecast to be in the 50s over the weekend.

During this weekends heat event, remember: 

* Stay hydrated and drink plenty of fluids.
* Wear lightweight and 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.

Minor coastal flooding is also expected at the time of peak high 
tide (evening/overnight) for bayshore locations along the San 
Francisco, San Pablo, and Monterey Bays this evening through next 
Thursday morning. Please see the CFW product we have out for 
additional details.

.LONG TERM...
Issued at 1211 PM PDT Fri Aug 7 2026
(Monday through next Thursday)

Temperatures begin a cooling trend on Monday as the ridge starts 
to flatten, yet the interior will still be quite warm. Northerly 
winds are forecast to increase and will result in hazardous 
conditions to small craft early next week as well, especially 
across the northern waters. Temperatures are then forecast to cool
to below seasonal averages late next week as troughing develops 
off of the West Coast.

.AVIATION...
(00Z TAFS)
Issued at 431 PM PDT Fri Aug 7 2026

Patchy MVFR-IFR stratus lingers at the immediate coast with high 
clouds over portions of the North Bay and the San Mateo Peninsula. 
Breezy and gusty onshore pattern winds continue into the evening 
hours. Overnight, stratus will gradually expand inland, with 
moderate to high confidence that the marine layer will compress as 
an upper level ridge builds over the region. If this compression 
does not occur, SJC could receive an MVFR ceiling early Saturday 
morning. Stratus will retreat to the immediate coast through 
Saturday morning with breezy onshore winds resuming in the afternoon.

Vicinity of SFO... VFR through the evening hours with moderate and 
gusty northwest winds. Moderate confidence that a ceiling will 
develop over the terminal early Saturday morning, with some high 
resolution model output depicting the stratus deck deflected to the 
north of the terminal. Stratus dissipates over the post-sunrise 
hours and breezy west-northwest winds develop Saturday afternoon.

SFO Bridge Approach... Similar to SFO.

Monterey Bay Terminals... VFR conditions continue for a couple of 
hours before IFR-LIFR stratus moves over the terminals early this 
evening, dissipating through the course of Saturday afternoon. 
Breezy northwest winds will diminish this evening and resume 
Saturday afternoon.

.MARINE...
(Tonight through next Wednesday)
Issued at 431 PM PDT Fri Aug 7 2026

Moderate northwest seas gradually build to rough (9-12 feet) as
northwest winds increase to fresh to strong by Saturday. Seas and
winds remain elevated through the middle of next week. Embedded
near  gale force gusts are possible across the outer northern
coastal  waters. A long period southerly swell (15 to 17 seconds)
persists  through the weekend.

&&

.FIRE WEATHER...
Issued at 1211 AM PDT Fri Aug 7 2026

Near-critical fire weather conditions persist through the weekend 
across the interior due to very hot and dry conditions. Strong 
thermal belting, extended burn periods, elevated PIG, and near or 
record BI/ERC values are expected. Temperatures will be 10 to 15 
degrees above normal with a compressed marine layer. Poor minimum 
daytime relative humidity as low as 10% in the afternoons with 
little-to-no recovery overnight is expected with nocturnal drying in 
the highest terrain. Even with critically dry conditions, wind is 
the limiting factor preventing this from being a Fire Weather 
Watch/Red Flag Warning event. Outside of the diurnal sea breeze that 
will bring breezy conditions in the afternoons and evenings through 
gaps and passes, onshore flow will be light. Additionally, critical 
conditions are not expected to meet coverage or duration 
requirements to warrant a product.
