.SHORT TERM...
Issued at 121 PM PST Mon Mar 2 2026
(This evening through Tuesday)

Mostly to party cloudy sky conditions are being observed this 
afternoon in wake of the exiting mid/upper level trough that brought 
light precipitation to the region. Maximum temperatures are forecast 
to be in the low-to-mid 60s (isolated spots across the interior 
Central Coast may reach the lower 70s). Overnight, expecting low 
clouds to return to much of the region and spread inland into early 
Tuesday morning. 

By Tuesday afternoon, temperatures will warm slightly (by a few 
degrees or so) as a weak shortwave ridge returns to the region. 
However, temperatures look to remain around or slightly 
above seasonal averages.

.LONG TERM...
Issued at 121 PM PST Mon Mar 2 2026
(Tuesday night through next Sunday)

Another trough is forecast to move across the region on Wednesday 
morning, brining a slight chance of light rain to the North Bay. 
However, the precipitable water values do not appear to be high 
enough for widespread rainfall with the frontal passage. In wake of 
the frontal passage, northwesterly winds will increase with gale 
force gusts likely across the ocean, near the coast, and in the 
higher terrain through Friday. Additionally, much drier conditions 
are forecast through late week, driest in the higher elevations. 

The mid/upper level pattern then shifts to more of an inside slider 
type event bringing offshore flow to the region by Friday and 
Saturday. This would bring offshore flow to the region with 
temperatures warming into the low to mid 70s across much of the 
region during this upcoming weekend. Please keep up to date with the 
latest forecast information throughout the week.

.AVIATION...
(00Z TAFS)
Issued at 419 PM PST Mon Mar 2 2026

It's VFR under diurnal surface warming and boundary layer mixing
under a weak subsidence temperature inversion aloft. Post sunset 
loss of daytime surface heating will lead to diminishing strato-cu
clouds over land. Onshore winds and the onset of radiative cooling
will then bring increasing maritime low clouds /IFR-MVFR/ to the 
coastline and partially inland tonight and Tuesday morning. Low 
clouds will mix out by late Tuesday morning and early afternoon 
for a return to VFR.

Vicinity of SFO...VFR continues through early-mid evening due to 
plenty of mixing in the boundary layer. Then there's an increasing
probability of low clouds /MVFR/ developing tonight/early Tuesday
with tempo 09z-12z then prevailing MVFR until 19z Tuesday. VFR 
Tuesday afternoon and evening. West wind 5 to 15 knots, strongest 
in the afternoon to mid evening hours.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR continues through early to possibly 
mid evening, then increasing probability of low clouds /MVFR/ 
tonight and Tuesday morning. VFR by late morning Tuesday. Onshore 
winds 10 knots diminishing and becoming light southeasterly tonight
and Tuesday morning. Onshore winds redevelop Tuesday afternoon.

.MARINE...
(Tonight through next Saturday)
Issued at 326 PM PST Mon Mar 2 2026

Gentle northwest winds will increase to a moderate to fresh
breeze on Tuesday. Conditions will continue to deteriorate
Wednesday through Friday with strong to gale force north winds
developing across the waters. These winds will build very rough
seas of 12 to 15 feet across exposed waters.
