Area Forecast Discussion National Weather Service San Francisco Bay Area 453 PM PDT Wed Aug 5 2020

SYNOPSIS. Unseasonably cool conditions will persist through Thursday as temperatures slowly adjust toward near normal for the weekend. Drizzle or light rain is possible in coastal regions Thursday morning.

DISCUSSION. as of 02:21 PM PDT Wednesday . Afternoon satellite continues to show a deep marine layer impacting the the Bay Area. Breezy northwest winds are pushing this in the coast in most areas with some dry slots in the lee of prominent points such as Point Arena and Pigeon Point. These dry slots are keeping areas like coastal Sonoma and the Santa Cruz/Aptos area clear. As the winds ease overnight clouds should make a return into the Bay. However, the upper trough slowly creeping across the region may provide enough vertical mixing to clear out the region earlier on Thursday. This will be the challenge for the next 24 hours. For now the forecast indicates that we'll see a marine layer like this morning, but may need to show more clearing earlier. With the trough coming through, models are indicating the possibility of some light rain/drizzle in some coastal areas. This should be confined to the coastal areas, but with the deepening marine layer it may reach a little way inland. By Friday the upper trough will be shifting off to the east, allowing for a ridge to build over the region. This should compress the marine layer a bit causing a earlier burn off and slower onset. This means more daylight while the ridge is in place which yields a warming pattern. This pattern should hold through Saturday. Sunday will be a bit of a transition day as the ridge flattens out and as a trough over the Pacific Northwest begins to slowly dig southward once again. So as we get back into early next week, expect temps to drop to a few degrees below normal.

All told, the marine layer will play a significant role for the next day or two. Temps will slowly rise to near normal for the first part of the weekend with a slow slip to below normal for early next week.

As for winds, look for continued breezy conditions for the next day or two. As the ridge steps in and then the pattern flattens, winds should be easing quite a bit.

AVIATION. As of 04:52 PM PDT Wednesday . for 00z TAFs. A mix of MVFR to VFR conditions with stratus clouds streaming into the San Francisco Bay as well as the Monterey Bay. Cloud cover will thicken with cigs lowering to MVFR/IFR overnight. The marine layer is deep, around 3000 feet, so there remains another chance for light drizzle in the early morning hours, but again mostly closer to the coast. Clouds will have another late clearing on Thursday at most terminals after 18z. Winds remain breezy and onshore with several terminals having stronger gusts. This pattern will continue into Thursday with strongest winds at KSFO.

Vicinity of KSFO . MVFR. Winds remain onshore with stronger gusts from 25-30 kt. Low confidence in gusts exceeding 30 kts as they are expected to diminish overnight. MVFR ceilings will persist through the night and dissipate after 18z. VFR Thursday afternoon with strong onshore winds.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals..MVFR. Onshore winds have increased featuring some stronger gusts. Cigs will lower for IFR conditions overnight as winds decrease. Low confidence in chances for LIFR at KMRY. Cigs will lift after 18z, but cloud cover will remain around the terminals for MVFR conditions. Winds will increase Thursday afternoon with occasional stronger gusts.

MARINE. as of 02:01 PM PDT Wednesday . Moderate to breezy northwest winds will continue across the waters through late this week. Winds will ease slightly over the southern outer waters and parts of the coastline tomorrow with gusty conditions persisting elsewhere. Breezy winds are expected into early this evening over the San Francisco Bay around the Golden Gate Gap and northward through the Delta. These winds will generate steep fresh swells resulting in locally hazardous seas, especially for smaller vessels. A couple of light southerly swells will continue into the weekend.

MTR WATCHES/WARNINGS/ADVISORIES. Tngt. SCA . Pt Arena to Pt Reyes 0-10 nm SCA . Pt Reyes to Pigeon Pt 0-10 nm SCA . Pt Arena to Pigeon Pt 10-60 nm SCA . Pt Pinos to Pt Piedras Blancas 0-10 nm until 3 AM SCA . Pigeon Pt to Pt Piedras Blancas 10-60 nm from 9 PM SCA . SF Bay until 9 PM
