Area Forecast Discussion National Weather Service San Francisco Bay Area 246 PM PST Thu Feb 20 2020

SYNOPSIS. Warming temperatures continue through the end of the week as the next system passes to the south. A chance of rain is possible for the Central Coast late Friday into Saturday morning, though accumulations are forecast to be minimal. The Bay Area will see dry conditions and mild temperatures are forecast to continue through next week.

DISCUSSION. as of 03:00 PM PST Thursday . Another dry and mild February day is now well underway with increasing high clouds from the west and slightly warmer temperatures versus this time yesterday. Current observations are generally running with temperatures in the mid 60s near the shorelines up to the low 70s inland, which are about 3-7 degrees above normal.

For tomorrow, 850mb temperatures are forecast to rise by another 1-2C which will directly result in further warming at the surface by an additional 3-7 degrees (F). Consequently, tomorrow will run approximately 6-14 degrees above normal, with shoreline temperatures forecast in the mid to low 70s and up to the mid 70s farther inland. High clouds will lower and thicken later in the day and the farther southward a location is.

The primary weather system in the region is a 553dm 500mb low pressure system approximately 500 miles WSW of San Francisco. Moist southwesterly flow on the southeastern flank of the low is responsible for todays increasing high clouds. This system has trekked roughly 120 miles southward since this morning which is in line with the varying forecast model trajectories that guide it into Southern California late Friday into early this weekend. Wrap around moisture on the north/eastern periphery of the upper low may bring the first measurable rain of the month for some portions of Santa Cruz, southern Santa Clara, Monterey, and San Benito counties as it slides well to our south of our location and into Southern California. Moderate amount of uncertainty remains on which areas will pick up any area, with the highest certainty for the coastal ranges of Monterey (Big Sur) for picking up at least a hundredth. Elsewhere, areas such as Monterey, Salinas, Hollister, and the Santa Cruz mountains will be looking in the range of 0.01-0.10", while the peaks of Big Sur could see 0.05-0.50" per latest ensemble member output. That said, dry ensemble members remain for all locations, meaning there is still a possibility of the system coming in slightly farther southward, or weaker/drier than anticipated, resulting in less or no precipitation for some/all areas mentioned. Any rain that does fall with this system would be the first for the area this month, aside from any trace amounts accumulated during the morning fog events. Winds should remain light to occasionally breezy with this system.

In the wake of this low passing to our south, a short lived, low amplitude (weak) high pressure will develop over the area later Saturday. This will be the driving factor for the increase in 850mb temperatures previously discussed and will also tighten the pressure gradient, causing locally moderate winds along the coast and through coastal gaps, such as near KSFO from later Saturday and throughout Sunday. A low pressure trough will sweep across the Pacific Northwest late this weekend but will not bring a tangible impact to the local weather. A broader, higher amplitude high pressure system will then develop early next week, pushing 850mb temperatures up to 10-13C from Tuesday through Thursday -- resulting in further dry, mild weather for the region.

AVIATION. as of 9:34 AM PST Thursday . For 18Z TAFs. VFR conditions are forecast to prevail through the period with passing high clouds. Winds are forecast to remain rather light today.

Vicinity of KSFO . VFR conditions expected with passing high clouds. Light winds this morning will eventually become west/northwest this afternoon around 10 kt.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . VFR with increasing high clouds. Light offshore winds this morning will become onshore later today.

MARINE. as of 02:00 PM PST Thursday . Light northwesterly winds are forecast to prevail over the coastal waters today. A low pressure system will arrive on the Central Coast on Friday, bringing with it a chance of light rain to the waters south of Point Pinos. Dry weather returns Sunday and Monday. A moderate northwest swell persists through the week along with a light southerly swell.

MTR WATCHES/WARNINGS/ADVISORIES. Tngt. None.

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.
