Area Forecast Discussion National Weather Service San Francisco Bay Area 448 AM PDT Wed Apr 8 2020

SYNOPSIS. Isolated to scattered rain showers will be possible over the Central Coast through midweek while mainly dry conditions prevail to the north. Temperatures will begin a gradual warming trend late in the week and into the upcoming weekend as conditions dry out region-wide.

DISCUSSION. as of 2:55 AM PDT Wednesday . The pesky low pressure system that brought a variety of weather to the Bay Area and Central Coast the last few days remains off the coast. Overnight satellite imagery shows a broad circulation, with embedded smaller circulations, spinning near the Channel Islands. The cyclonic flow continues to advect moisture around the slow moving low pressure. The advecting moisture has resulted in bands of scattered showers moving over the San Joaquin Valley and southern Monterey/San Benito. Over the last six hours a few gauges have tipped in southern Monterey/San Benito with a few hundredths up to a few tenths. It should be noted shower activity is struggling to have any additional northern movement. Latest hi-res models, like the HRRR and local WRF, keep showers chances through day, but mainly south of San Jose. In fact, most likely locations for showers will still be confined to Monterey/San Benito, but a stray shower could drift north. The cold low pressure will make for an interesting split with temperatures around the Bay Area/Central Coast. Southern areas will remain seasonably cool with filtered sunshine/showers (Monterey Bay region southward) and northern areas will be mild an in a few spots above normal (San Jose northward).

For tonight, the low finally moves eastward and begins its slow exit of California. Before it finally exits a few additional bands of showers may drift across the forecast area Wednesday night and Thursday. Once again, best chance for precip will be south of San Jose. Additional rainfall will generally be light. Given the recent rain and lingering low level moisture patchy fog will be possible Wednesday night and early Thursday.

Showers will end by Thursday night with a warming and drying trend developing. Warmer and drier conditions are expect over the weekend and into early next week.

AVIATION. as of 4:46 AM PDT Wednesday . for 12Z TAFs. A thick layer of stratus sits just off the coastline over the ocean, while higher clouds spill over head associated to the weather system over Southern California, tracking southeast. MVFR to VFR at this hour. Locally varying winds will transition back to onshore and strengthen in the afternoon as cloud cover lingers providing MVFR conditions possible through the TAF period.

Vicinity of KSFO . MVFR at KSFO and KOAK due to stratus clouds spilling into the Bay, with VFR elsewhere. Cigs are forecast to lift to around 3,000 feet in the afternoon. Lower clouds for MVFR conditions return in the evening for the remainder of the TAF period. Winds are breezy and will re-strengthen and be onshore in the afternoon.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . Closer to the coast, winds are breezy with cigs around 1,500 feet and MVFR conditions. Farther inland and winds are calmer with VFR. Winds will become onshore and strengthen in the afternoon with cigs only lifting to around 2,500 feet. Isolated showers are possible in the evening.

MARINE. as of 02:37 AM PDT Wednesday . The low pressure system continues to slowly move over southern California and farther inland. Northwest winds will remain breezy through the morning and then decrease. Lightly scattered showers over the southern waters are possible. Northwest swell through the week, with a long period southerly swell that gradually decreases.

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