.SHORT TERM...
Issued at 1210 PM PDT Fri May 29 2026
(This evening through Saturday)

The mid/upper level low that provided recent rainfall across the 
region has shifted over Nevada with a short-wave ridge building in 
from the Pacific. A mix of sun and clouds are expected throughout 
the afternoon as PWAT values remain ~1.00" and lingering surface 
moisture is abundant. Thus, cloud cover may limit how warm 
temperatures get today. We are forecasting maximum high temperatures 
to be in the upper 50s to middle 60s near the coast with middle 60s 
to lower 70s across the interior. 

Expecting low clouds once again tonight with the potential for fog 
in the North Bay (mainly around Santa Rosa, Petaluma, and Navato) 
and coastal drizzle around the Monterey Peninsula. Any low clouds 
and/or fog that does develop is expected to clear out by midmorning 
(Saturday). As the ridge aloft shifts further to the east over the 
region, expecting the warming trend to continue on Saturday with 
high temperatures ranging from the upper 50s along the immediate 
coastline, low to middle 60s just inland, and lower to upper 70s in 
the interior.

.LONG TERM...
Issued at 1210 PM PDT Fri May 29 2026
(Saturday night through next Thursday)

Zonal flow will return to the region through the middle of the 
upcoming week while 500mb heights warm slightly. This will result in 
a warming and drying trend across the interior. By Monday and moreso 
into Tuesday, the marine layer is forecast to return resulting in 
cooler temperatures in coastal locations versus inland as low clouds 
will be slower to dissipate each morning. Conditions look to cool 
by late in the work week as troughing approaches the West Coast.

.AVIATION...
(18Z TAFS)
Issued at 1050 AM PDT Fri May 29 2026

Ample low level residual moisture led to widespread strato-cu and
stratus across all terminals this morning and even into this
afternoon. Thankfully, CAT is mostly MVFR and into VFR. There are
some hints for a few hours this afternoon of SCT to VFR CAT. Once
the sun sets and conditions cool we'll see lower CIGs redevelop
early this evening. STS on the other hand has some signs for dense
fog tonight and went for it with 1/2sm for a few hours early Sat.
Overall conf is medium.

Vicinity of SFO...Solid of stratus continues to roll off the 
hills. Will keep the MVFR CIGs through at least 23Z. Def low conf,
but a few hours SCT are possible (20-40%) before CIGs return
tonight into early Saturday.

SFO Bridge Approach...Similar to SFO holding on to CIGs.

Monterey Bay Terminals...Seeing better signs of MVFR
transitioning to VFR early this afternoon. MVFR CIGs return 
tonight.

.MARINE...
(Today through Wednesday)
Issued at 1050 AM PDT Fri May 29 2026

High pressure building in from the north will lead to increasing
northerly winds over the coastal waters this afternoon. Moderate
to fresh northerly breezes will persist tonight and into the
weekend with the strongest winds over the northern outer waters.
Occasional gale force gusts will occur the north of the Golden
Gate and along the Big Sur Coast.
