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.

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.

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.

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.
