Area Forecast Discussion National Weather Service San Francisco Bay Area 412 PM PST Sun Jan 19 2020

SYNOPSIS. Seasonably cool and cloudy conditions will persist over the region on Monday with a slight chance of light rain developing near the coast. Rain chances increase region-wide on Tuesday as a weak frontal system drops southward. Mostly dry conditions are then expected for the remainder of next week, with rain possibly returning next weekend.

DISCUSSION. as of 01:45 PM PST Sunday . High clouds over the entire region and low clouds that have advected into the interior portion of the East Bay have held temperatures down this afternoon, especially in the latter. Meanwhile, a few locations are actually warmer than 24 hours ago as the air mass aloft has warmed slightly. Regardless, still a cool day region-wide with most locations in the upper 40s to middle 50s with only a few additional hours of warming potential. A few locations have reached into the lower 60s where the sun was able to break out for a bit longer along with the aid of light offshore flow.

Light onshore flow is forecast to return region-wide on Monday ahead of an approaching mid/upper level trough. This will increase low level clouds with continued mid/high level clouds still streaming inland as well. A weak disturbance continues to be forecast to approach central California on Monday, ahead of the main system. The ECMWF and other forecast models continue to depict light precipitation developing along the coast and around the Monterey Bay region as early as Monday afternoon/evening, yet rainfall will generally be light. Rain chances will increase from north to south on Tuesday as a frontal system pushes inland and to the south. Precipitation chances and rainfall amounts will be best over the North Bay and taper off southward over the Central Coast as the system dissipates. Overall, looking for 0.25" to 0.50" north of the Golden Gate, 0.10" to 0.25" around San Francisco and in the Coastal ranges while 0.10" or less is likely inland and to the south. Conditions will begin to dry out by Tuesday night as the system exits the region.

Mainly dry weather and seasonably cool temperatures will persist through the remainder of the forecast period. Meanwhile, weak systems will pass inland to the north with very light precipitation possible as far south Napa and Sonoma Counties from Thursday night into Friday, yet widespread precipitation appears unlikely at this time. Unsettled conditions then appear possible region-wide by next weekend in response to another mid/upper level trough approaching from the west.

AVIATION. as of 4:12 PM PST Sunday . For 00z TAFs. Extensive cloud cover over the east Pacific is overlapping CA/NV to British Columbia. In our cwa, very light precipitation as snow is evaporating (virga) at 12 to 16 thousand feet agl (air temps 20s/teens) above a lower level temperature inversion. Cloud thickness is obscuring the areal coverage of low clouds over the Central Valley, part of which is entering the East Bay, Byron Airport reports 4 miles visibility in mist and overcast 800 feet. All other airports report VFR except KHAF reports MVFR 3-5 miles visibility in haze.

The synoptic pattern favors a continuation of mainly weak surface based offshore pressure gradient and winds, combined with a lack of ocean/land temperature contrasts negates a maritime influence (sea breezes) through tonight and Monday morning. However, by Monday afternoon light onshore winds could develop locally on the coast. VFR is forecast, lowest confidence is in areal coverage of fog and/or low clouds in the East Bay valleys tonight and Monday morning.

Vicinity of KSFO . VFR. Light N-NE wind tonight becoming SW Monday.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . VFR. Light E-SE winds except up to 10 knots in the Salinas Valley, winds onshore 5 to 10 knots Monday afternoon.

MARINE. as of 3:24 PM PST Sunday . Generally light offshore winds will persist across the coastal waters tonight as high pressure remains over the Great Basin. Winds will increase and turn southerly on Monday ahead of an approaching frontal system that will move through the waters on Tuesday. A long period, building northwest swell will arrive midweek generating hazardous seas conditions for small vessels.

MTR WATCHES/WARNINGS/ADVISORIES. Tngt. NONE.
