Area Forecast Discussion National Weather Service San Francisco Bay Area 327 PM PST Sun Dec 15 2019

SYNOPSIS. Blue skies surround the Bay Area and Central Coast on Sunday, with a few straggling showers over the ocean. Light northerly winds will shift to slightly off shore tonight. With minimal cloud cover and cooler air, cold overnight low temperatures are forecast around the region for Monday morning, which will be the coldest of the week. As high pressure builds dry air returns with warmer temperatures. Unsettled conditions return by midweek bringing the next chance for rain; and potentially again late next weekend.

DISCUSSION. as of 01:44 PM PST Sunday . An upper level ridge is building over the California coastline. This is allowing high pressure to provide clearer skies across the region for what seems like since Thanksgiving. There are still a few lingering isolated showers over the Pacific, but are not forecast to come over land. Winds are light and out of the north and will slowly shift over the course of the day to offshore. The light, dry offshore winds will inhibit any fog in the overnight hours. However, the lack of clouds will promote more cooling allowing for minimum temperatures to reach their lowest for this week. Widespread low-40s to upper 30s are expected around the Bay Area and Central Coast. Isolated areas of the North Bay Valleys, the East Bay Valleys, and Southern Monterey Interior County will be in the mid-30s just above freezing. Patchy frost in these areas may be possible.

The ridge will continue to build on Monday ushering in drier air and providing a warming trend, giving further confidence that Monday's the overnight lows tonight will be the minimum for the week. Seasonal Temperatures on Monday and Tuesday before the return of unsettled weather.

The next upper level trough moves in from the west on Tuesday night, bringing with it a weather system that will bring the next opportunity for rainfall for the region. Rainfall will be light to moderate at times and last through Wednesday morning, with spotty showers lingering over the area after the brunt of the system passes. Compared to what we have seen recently, accumulations will be minimal, with most areas seeing less than a half an inch. However, higher elevations of Marin County and the Santa Cruz Mountains, as well as coastal San Mateo could see up to an inch.

The trough-ridge-trough "rinse, repeat" pattern continues as high pressure tries to build on Thursday. But models are showing the next ridge to be too weak which will allow zonal flow to set up for the end of the work week. With consistent onshore flow drawing moisture in from the ocean, it would not be surprising if the the overcast skies with occasional pop-up showers/drizzle that we saw last week are seen again Thursday and Friday. The next system will approach the coast when the next trough moves in. Models are still disagreeing on timing, though it is looking more and more like a Saturday night into Sunday event. More to come as we get closer and models can better resolve the event.

AVIATION. as of 03:27 PM PST Sunday . For 00Z TAFs. VFR conditions to prevail through the period, aside from possible reduced vis at KSTS tomorrow morning. Current obs and satellite show FEW to SCT cumulus at 2500-5000 ft AGL. FEW to SCT clouds expected to hang around into this evening before diminishing overnight. W to NW winds this afternoon 10-15 kt with local gusts to around 20 kt into this evening. Winds will diminish overnight before N to NE winds develop by tomorrow morning.

Vicinity of KSFO . VFR with FEW to SCT clouds at around 3500-4500 ft AGL. Expecting low clouds to clear out this evening and tonight. W to NW winds around 15 kt this afternoon diminishing this evening. Winds expected to turn offshore by the morning.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . VFR through the period with FEW to SCT low clouds at around 3500 ft AGL. W to NW winds 10-15 kt with locally breezy winds at KMRY this afternoon. Winds to diminish overnight.

MARINE. as of 01:44 PM PST Sunday . Northwest winds will be breezy today as a coastal trough develops over southern California while high pressure builds offshore. Moderate to large northwest swell will gradually subside into early next week. The combination of gusty winds and large combined seas will create hazardous seas conditions through this evening, particularly for smaller vessels. Southerly winds will return later on Monday ahead of the next weather system.

MTR WATCHES/WARNINGS/ADVISORIES. Tngt. SCA . Pt Arena to Pt Reyes 0-10 nm until 10 PM SCA . Pt Reyes to Pigeon Pt 0-10 nm until 10 PM SCA . Pigeon Pt to Pt Pinos 0-10 nm until 10 PM SCA .
