Area Forecast Discussion National Weather Service San Francisco Bay Area 417 AM PST Thu Feb 27 2020

SYNOPSIS. Unseasonably mild and dry conditions will persist over the region through the remainder of February. A weather system will approach from the northwest this weekend, bringing cooler temperatures and the potential for light precipitation by Sunday.

DISCUSSION. as of 02:52 AM PST Thursday . Another quiet night across the Bay Area with mild and dry conditions. Satellite imagery shows mainly clear skies with only high clouds streaming in from the SW. The high clouds are associated with an upper level low sandwiched between Hawaii and Baja. Only other item of note on the satellite is a patchy low clouds off the North Bay Coast. Not expecting any impacts, but they may creep toward the coastline by sunrise.

If you liked the weather on Wednesday you'll like the forecast for Thursday and Friday. Temperatures will remain above normal and mainly in the 60s near the coast and 70s inland. A few spots may eclipse 80 across the far interior. Temperatures will cool a few degrees on Friday, but it will be only a few degrees.

The ridge of high pressure that is currently bringing the nice weather will weaken Friday into Saturday as a trough of low pressure approaches from the north. The temp drop from Friday to Saturday will be on the order of 10-15 degrees. Despite the big cool down temperatures will actually be returning to more seasonable levels - highs in the 60s. Winds will increase a tad on Saturday as well with increasing onshore flow.

Now to the main event - the approaching trough is still on track to deepen and become a cutoff low Sunday into Monday. For a while it looked like this trough/low would bring the first rain to the Bay Area since late January. The trend the last few days hasn't been favorable for a rainy scenario. The latest 00-06Z is keeping the drier scenario - including the higher resolution NAM that is now capturing Sunday. The ECMWF had split precip over the Sierra and off the coast keeping San Francisco dry. The other models are now coming into to agreement with the ECMWF solution. there are still a few ensembles keep some rain place for Sunday, but not much. One item that is more certain is this trough/low will usher in a much colder airmass. The cold air will lower snow levels and make the airmass more unstable. The instability probably won't be enough for thunderstorms, but could result in a more convective showery regime. Therefore, won't completely remove precip chances, but definitely trending drier. Most likely areas for any precip would be south of San Jose. If showers do develop higher elevation snow is possible given the low snow levels. It will also feel blustery on Sunday given the colder temperatures and increasing winds.

Quick rebound on Monday as high pressure rebuilds with mild and dry conditions next week. Looking down the road much farther models hint at some additional precip chances around the 7/8th of March, but it doesn't look promising.

At this rate, it looks like San Francisco will be dry for February, which will tie the zero precip record from 1864. If one projects precip farther out San Francisco may not tip a bucket until after March 7. If that holds true it could put San Francisco near the longest dry streak during the wet season, which currently stands at 43 days.

AVIATION. as of 4:00 AM PST Thursday . For 12Z TAFs. Mainly clear skies will prevail through the period with a few scattered high clouds anticipated to stream across the region. Light winds will prevail through the morning with moderate onshore flow through the afternoon.

Vicinity of KSFO . VFR conditions will prevail through the forecast period. Light and variable winds will persist through the morning with moderate onshore flow expected this afternoon.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . VFR conditions will prevail through the forecast period. Light and variable winds will persist through the morning with moderate onshore flow expected this afternoon.

MARINE. as of 2:55 AM PST Thursday . Relatively light northerly winds will prevail across the coastal waters today and Friday. Northerly winds will begin to strengthen over the northern outer waters Friday afternoon as a low pressure system slides south across the region. Strong northerly winds will spread south through the weekend and into next week. A moderate longer period northwest swell will move across the coastal waters through the end of the week. Another long period northwesterly swell is anticipated to move across the region over the weekend.

MTR WATCHES/WARNINGS/ADVISORIES. Tday. NONE.

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.
