Area Forecast Discussion National Weather Service San Francisco Bay Area 505 PM PST Thu Dec 5 2019

SYNOPSIS. Gearing up for another cold front which will sweep through the area late Friday and Saturday resulting in widespread rainfall and gusty winds. Post-frontal showers and potentially isolated thunderstorms will continue through Saturday night before tapering off on Sunday.

DISCUSSION. as of 1:56 PM PST Thursday . Under mostly cloudy skies, area temperatures are mild, ranging from the mid 50s to lower 60s, which are warmer than yesterday at this time by several degrees. Tonight is expected to see low temps generally from the mid 40s to lower 50s.

The next storm system is due impact the area on Friday and Saturday with rainfall and gusty winds. Light showers are expected to begin Friday ahead of this system. The cold front is expected to move into the North Bay late Friday afternoon then gradually moving south and east overnight. Given the dynamics with the potent cold front and ample moisture, rainfall intensity will be of concern across the North Bay, especially in the Kincade Burn area. Hourly rainfall rates could exceed one half an inch in an hour leading to debris flows or flash flooding. Therefore, a Flash Flood Watch has been issued for the Kincade burn area Friday afternoon through Saturday morning. By Saturday morning the cold front will have pushed through much of the Bay Area. However, the parent low and upper trough moving through will keep showers going across the Bay Area Saturday into Sunday. Enough instability will be present with the frontal passage and with the upper trough to justify a slight chance of thunderstorms for Friday and Saturday. Rainfall totals from Friday into early Sunday range from 0.50"-1.25" in most urban areas, except 1.50-2.50" in the North Bay Valleys. In the hills/mountains, rain totals are forecast to range from 1.50"-4.00" in the North Bay Mountains, 1.25- 1.5" for the East Bay Hills, 1.50-3.00" in the Santa Cruz Mountains, and 1.00-3.00" across Monterey and San Benito Co. Mountains. Lesser amounts will be possible in the southern Salinas Valley.

In addition to the rain, southerly winds will ramp up ahead of and with the frontal passage. Winds will be strongest over the coastal waters, near the coast, through south-east oriented valleys, and in the higher terrain. A wind advisory has been issued for the entire CWA from 10 AM Friday through 7 AM Saturday. Although the advisory is for the entire area, there will be wind- sheltered areas that will see lesser wind speeds, including the Monterey Bay coastline, and in the southern portion of the Santa Clara Valley.

Lingering showers will be possible on Sunday as the upper trough slowly exits. High pressure aloft building in over the state will bring drier weather to the area Monday through at least Wednesday. A weak system is forecast to move across Northern California on Wednesday which could bring a few showers to northern zones late Wednesday, although latest model runs have weakened this system further.

AVIATION. as of 5:00 PM PST Thursday . Low confidence on cloud forecast. Models indicate abundant low level moisture over the area through the evening so the latest forecasts call for MVFR cigs impacting SFO and the approach. S-SE winds begin to pick up above the surface tonight causing possible LLWS. Winds at the surface increase Friday morning ahead of the next frontal system. Light rain should reach the Bay Area Friday afternoon.

Vicinity of KSFO . Cigs will be in and out of MVFR range through the night. Bases predominately 3000-4000 ft. LLWS possible overnight tonight when winds at 2000 ft increase while surface winds stay light. Surface winds increase after 15Z with gusts to 15 kt. These winds will only increase as the day goes on Friday.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . Cigs remaining in the VFR range. South winds increasing in the Salinas Valley with gusts to 20 kt after 14Z.

MARINE. as of 04:48 PM PST Thursday . Southerly winds will continue to steadily strengthen into tonight and tomorrow morning ahead of an advancing cold front. Gale force winds are expected by early Friday and persist through Friday night. Moderate northwest swell will gradually build to around 10 to 15 feet Friday over the northern waters then spread south across the coastal waters over the weekend.
