Area Forecast Discussion National Weather Service San Francisco Bay Area 959 AM PST Fri Dec 6 2019

SYNOPSIS. Southerly winds will continue to increase today ahead of an incoming cold front. Rain will develop across the North Bay this afternoon and then spread southward tonight. Showery and cool on Saturday with isolated thunderstorms possible. Lingering showers on Sunday but trending drier by afternoon. Dry weather returns Monday and Tuesday with a slight chance of rain by midweek.

DISCUSSION. as of 8:52 AM PST Friday . Satellite imagery shows the approaching storm system approximately 640 miles due west of Cape Mendocino, with the associated frontal band nearing the North Coast. Latest computer models continue the trend of slowing down the arrival of this system. The 12Z Nam has the frontal band moving into Sonoma County just after 00Z (4 PM PST) and holds off rain in San Francisco until after 7 PM. The bulk of the rainfall with this first wave is forecast to fall in the North Bay, and to a lesser extent, the Santa Cruz Mountains. A second front will sweep through the entire district on Saturday and will bring more rainfall to the area through Saturday evening, along with a slight chance of thunderstorms with small hail possible. The upper low will then finally move south along the coast on Sunday keeping showers going in its vicinity as it exits the area Sunday night. Latest storm-total rainfall estimates still show some 3-4 inch maxes for the North Bay hills with 1.5-3 inches for the Santa Cruz/Santa Lucia mtns. Rain shadowed Santa Clara/Salinas Valleys 0.25-0.50 on average with 0.50-1.00 inch elsewhere through Sunday night.

The Flash Flood watch for the Kincade burn area still looks valid with all models showing a bullseye of qpf in that area and the front strongest as it moves through northern Sonoma county this evening. Will need to monitor any convective lines and short term rain rates that could lead to problems over the burn area.

A Wind Advisory remains in effect for all areas beginning later this morning and continuing into Saturday morning. Strongest winds are expected along the coast and in the higher terrain. Gusty southeast winds will persist well into Saturday as the second front moves through.

Dry weather returns Monday and Tuesday with seasonable temperatures as high pressure rebuilds. A weak front may try and knock into the ridge by Weds with a slight chance of rain but not expecting anything of significance at this time.

AVIATION. as of 10:00 AM PST Friday . For 18z TAFS. Storm system has once again slowed down in latest guidance, pushing the timing back versus the previous TAFs. Frontal boundary looks less robust as it pushes south of the North Bay as well. That said, expecting very unsettled weather throughout the TAF for the North Bay and the latter half of the TAF for the remaining areas. Many impacts to aviation with this system from wet runways, an extended period of low level wind shear at around 2000 feet, and erratic stronger winds mixing down to the surface, south-southeast winds, and generally MVFR ceilings. Rain showers will come and go in the wake of the front at many TAF sites, making it difficult to pin down the periods of intermittently worse conditions.

Vicinity of KSFO . System has slowed down, delaying times versus previous TAF. Periods of rain from 01-02Z onward now expected with wet runways. Southeast winds throughout the period, increasing in strength as front draws closer to the airport. LLWS at 2000 feet at generally 35-50kt through the TAF. Infrequent gusts will mix down to the surface of varying speed, some in excess of 35kt. Intermittent ceilings in the 2000-4000 foot range by the afternoon.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . Front is looking weaker by the time it makes it to KMRY/KSNS, thus, weakened winds and delayed timing in latest TAF. Fractured front arrives around 07-10Z tonight with trailing rain showers into the morning. Valley favored SE winds will bring very gusty conditions to KSNS through most of the TAF period, while KMRY could be wind sheltered for much of the event. That said, still expect to see limited LLWS / gusts at KMRY by late this afternoon.

MARINE. as of 09:49 AM PST Friday . A storm system will move through the waters from north to south over the next 24 hours, bringing unsettled weather today into the weekend. As a result, southerly gale force gusts will develop across the waters today. These winds will generate large wind waves and hazardous seas. Moderate west swell will gradually build to around 10 to 12 feet tonight and continue through Saturday night. Showers and isolated thunderstorms will be possible this evening through Saturday.
