Area Forecast Discussion National Weather Service San Francisco Bay Area 839 AM PST Sun Feb 23 2020

SYNOPSIS. Low clouds and onshore flow will persist through the morning with continued cool high temps today. Dry and warmer conditions will return throughout most of the week as high pressure builds over the state.

DISCUSSION. as of 08:39 AM PST Sunday . For portions of the Bay Area this morning it may feel more like summer than winter. Deep stratus is covering some of the inland valleys making it feel damp and cool. In fact, there have been numerous reports of drizzle. The ground was wet here at the forecast office in Monterey. Clouds will be somewhat slow to clear this morning, but once they do it will be a cool and pleasant Sunday afternoon. Highs today will generally be in the 60s.

No update needed at this time.

PREV DISCUSSION. as of 2:21 AM PST Sunday . A warming trend will begin on Monday and continue through the week as a ridge of high pressure builds over the state and weak northerly to offshore flow develops. High temperatures are forecast to be in the upper 60s to upper 70s, and overnight lows in the 40s through much of the week.

Medium range models continue to hint at rain chances a week from today when an upper low drops south from the Gulf of Alaska and then onshore over Southern California. More than a few ensemble members of both the GFS and the ECMWF indicate measurable rain on next Sunday, and at times throughout the following week. Keeping fingers crossed.

AVIATION. as of 4:52 AM PST Sunday . Low clouds rooted in quickly Saturday and have become more widespread overnight while surface to lower level cooling and onshore wind flow continues. Patchy fog has produced VLIFR vicinity KSTS with a calm wind. Gusty NW winds aloft over the Coastal North Bay and San Mateo Coast is resulting in low level wind shear (llws). KSTS VLIFR-LIFR in fog until 1630z and llws until 18z today. A strong northerly pressure gradient will pick up NW winds at KSTS by mid to late morning. To the south surface winds have been locally gusty onshore, and there have been a few reports of very spotty 0.01" in drizzle or very light rain in the East Bay Hills. Also, KMRY recently reporting light drizzle to very light rain with a MVFR ceiling. Expect a gradual lifting of cloud ceilings today, slowest closest to the coast. Additional very spotty light drizzle or very light rain until late morning.

Theta-e and temperature advection forecasts indicate a shallow cold front, surface to approx 925 mb, arriving this evening. The NAM hints at a few patches of light drizzle or light rain again tonight, 12z TAFs have included tempo IFR-MVFR ceilings, visibilities in light precip with the incoming cold front. Post cold front partial to complete clearing is likely overnight. Any precipitation that occurs will be too low for KMUX radar to pick up, surface observations helpful however.

Vicinity of KSFO . A solid low cloud feed is arriving this morning with a gusty west wind to 25 or 30 knots, MVFR ceiling likely through 19z today. West wind may ease a bit by later morning, could become gusty again in the afternoon. A period of light drizzle or very light rain with tempo group indicated 03z-07z and IFR-MVFR ceiling this evening. Gusty west wind for the overnight is likely.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . MVFR ceilings with patchy light drizzle or very light rain based on observations and recent model output. Ceilings MVFR-VFR in the afternoon then likely lowering to MVFR- IFR with an approaching cold front, tempo light drizzle/rain for the evening. Conditions improving to MVFR-VFR late at night into Monday morning.

MARINE. as of 2:08 AM PST Sunday . A cold front over the eastern Pacific will move southeastward over the coastal waters and bays this evening. Gusty northwest winds will continue through early week, winds gradually easing mid week. A long period northwest swell arrives mid week.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
