Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Moderate northwesterly winds will prevail across the coastal waters with occasional gale force gusts are possible through tonight and into Friday. These winds will produce fresh and steep wind generated waves, creating hazardous conditions for smaller vessels. Winds will begin to subside late Friday and into the weekend. A moderate, predominately winds driven, northwesterly swell will prevail through much of the forecast period.

Area Forecast Discussion National Weather Service San Francisco Bay Area 448 PM PDT Thu Apr 2 2020

SYNOPSIS. Dry weather conditions with slightly below normal temperatures today and tomorrow. A pair of storm systems arrive this weekend. The first system on Saturday will be mainly focused over the North Bay/Shoreline with breezy winds. The second stronger system arrives Sunday and will bring widespread rain, gusty southerly winds, isolated thunderstorms, cooler temperatures, and lingering showers through potentially much of next week.

DISCUSSION. as of 03:00 PM PDT Thursday . Satellite imagery shows clear skies from the North Bay through Big Sur early this afternoon with only a few clouds lingering around 75 miles offshore. High pressure is present offshore today and will gradually build ashore and begin to weaken through the next 36 hours. Afternoon highs are generally ranging in the low to mid 60s, which is near to slightly below normal for this time of the year. This comes after a chilly start to the day with widespread 30s to 40s and isolated patches of frost in the inland valleys. For tonight, expect similar but marginally warmer overnight lows by a degree or two. That said, patchy frost will be possible into the predawn and sunrise hours once again tomorrow morning, due particularly to a decrease in mixing winds forecast near the surface tonight. Tomorrow will be similar to today except with slightly cooler temperatures and increasing high level cloud cover arriving from the northwest ahead of the next storm system.

For the weekend, a pair of storm systems will arrive and bring unsettled weather throughout the weekend and into early next week. The first of these systems will be the weaker of the two, featuring a more tightly bound 542dm 500mb upper low skirting across extreme NW California. The frontal boundary ahead of the parent upper low will first bring rain (0.25-0.50") to the North Bay throughout the morning, before shifting focus to the SF Bay Area around midday Saturday (0.10-0.30"), and eventually weakening before shifting farther southward towards the Central Coast by the evening (0.05-0.20"). Moderate southerly winds will precede and accompany the surface cold front on the order of 10-20mph sustained with gusts 15-25mph.

Then, lingering isolated showers will persist overnight before the arrival of the next storm system early Sunday, a broader, more organized 530-535dm 500mb upper low. This second storm system is anticipated to bring approximately 2 to 3 times as much precipitation as the first storm system (0.50-1.00" regionwide for urban areas, 1.50-2.50" for coastal ranges), with gusty southerly winds (15-25mph sustained, gusts up 25-40mph), and a cooler, more unstable air mass arriving with it. The post frontal instability will allow for the deeper development of convection and with that, the possibility of hail and even thunderstorms. Snow levels will also drop down to as low as 3000-3500 ft in the post frontal environment into Sunday night, allowing for a dusting of snow amongst the highest peaks across the forecast region (and much more over the Sierra -- check out NWS Sacramento or NWS Reno for the Tahoe forecast). Latest model runs suggest the upper low will slow down as shifts southward into Southern California, extending the possibilities of linger/wrap around showers throughout much of next week.

AVIATION. as of 4:46 PM PDT Thursday . For 00Z TAFs. VFR as clear skies surround the region. Winds remain onshore and breezy, with isolated occasional stronger gusts. Winds will ease slightly overnight. Skies are expected to remain mostly clear with a few clouds above 1,500 feet. VFR forecast Friday as winds strengthen in the late afternoon/evening.

Vicinity of KSFO . Clear skies and VFR. Winds remain onshore and 15-18 knots with occasional stronger gusts. Winds will ease over night slightly, but remain breezy. Skies should also remain mostly clear and VFR, but cannot rule out a few midlevel clouds. Thursday will be VFR once again, with onshore winds ramping up in the afternoon ahead of the next system approaching.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . VFR with breezy onshore winds. Winds will ease overnight. A few clouds may develop over the peninsula, but are not currently forecasting lower than 1,500. VFR once again on Friday with stronger winds in the early evening.

MARINE. as of 02:14 PM PDT Thursday . Moderate northwesterly winds will prevail across the coastal waters with occasional gale force gusts are possible through tonight and into Friday. These winds will produce fresh and steep wind generated waves, creating hazardous conditions for smaller vessels. Winds will begin to subside late Friday and into the weekend. A moderate, predominately winds driven, northwesterly swell will prevail through much of the forecast period.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
