Area Forecast Discussion National Weather Service San Francisco Bay Area 908 PM PDT Sun Mar 29 2020

SYNOPSIS. Fog is possible in the valleys overnight, especially in the North Bay. A weak weather system may bring light rain to the North Bay on Monday while areas to the south remain dry. Dry conditions, along with seasonable temperatures, are forecast for most of the remainder of the week, although there are some signs of rain returning by late Friday or Friday night.

DISCUSSION. As of 9:05 PM PDT Sunday . Shower activity quickly dissipated after sunset this evening. Now that the upper trough responsible for today's showers has moved well to our east, any additional shower activity overnight is highly unlikely. However, a few sprinkles overnight can't be ruled out given that the latest NAM and HRRR both show isolated light precip persisting. Primary concern overnight is for late night fog development where clouds clear. Fog late tonight and Monday morning is most likely in the North Bay Valleys.

Evening IR satellite imagery shows the next system moving inland to our north across the Pacific Northwest. Latest short-term models indicate that northern Sonoma County and northern Napa County could see some light rain from this system on Monday. Elsewhere, Monday is expected to be a dry day under partly cloudy skies with seasonable temperatures.

Dry weather should continue region-wide for most of the remainder of the work week. The warming trend that was expected for much of the week ahead now looks as though it may not materialize. Previous model runs had forecast a building upper ridge near the West Coast through much of the week. Latest models now maintain a cyclonic flow aloft over California as a longwave trough persists just to our east. Thus, only slightly warmer temperatures are anticipated from Tuesday through Friday, with high temperatures mostly remaining in the 60s. In addition, forecast confidence in dry weather through the week has diminished as the latest deterministic model runs of the GFS and ECMWF indicate rain potential across at least the northern portion of our area late Friday or Friday night.

Longer range models indicate mostly dry conditions next weekend, but then the potential for development of a wet pattern during the following week.

AVIATION. as of 4:30 PM PDT Sunday . Showers decreasing this afternoon as upper level low moves south of the district. However abundant low-level moisture will allow MVFR cigs to reform tonight. In addition models still show a few stray showers mainly over the coastal hills and MRY through 06Z. Patchy fog possible in the North Bay late tonight. The next system will bring rain to the North Bay Monday afternoon.

Vicinity of KSFO . VFR/MVFR with cigs 4000-5000 ft lowering to 3000-4000 ft after 06Z. West to northwest winds 10-15 kt decreasing after 04Z.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . Cigs above 5000 ft lowering to near MVFR range tonight.

MARINE. As of 9:05 PM PDT Sunday . Low pressure off the Pacific Northwest and high pressure off the central and southern California coast will result in stronger winds over the southern waters off Big Sur. As the high builds northward by midweek northwest winds will increase. Mixed swell will persist with a moderate northwest swell and a light southwesterly swell.

MTR WATCHES/WARNINGS/ADVISORIES. Tngt. NONE.

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