Area Forecast Discussion National Weather Service San Francisco Bay Area 1004 AM PST Thu Nov 21 2019

SYNOPSIS. Gusty winds in the North and East Bay mountains will decrease this morning. Dry conditions, along with seasonable temperatures, are forecast today through the upcoming weekend. Rain chances will develop by late Tuesday of next week and possibly impact the Thanksgiving holiday.

DISCUSSION. as of 09:06 AM PST Thursday . Mainly clear sky conditions and light winds resulted in a chilly morning over much of the region. Temperatures are now warming into the upper 40s to middle 50s and will top out in the lower/middle 60s for much of the region this afternoon. Low level clouds are impacting much of Santa Cruz County this morning under moist southerly flow. Elsewhere, look for dry and mostly sunny conditions through the day. With this said, the ongoing forecast remains on track with no updates needed at this time. Please see the forecast discussion below for additional details.

PREV DISCUSSION. As of 3:19 AM PST Thursday . Latest automated observations indicate some gusty offshore winds are still occurring in the North and East Bay Hills with wind gusts generally in the 30-40 mph range. However, relative humidity values are over 30 percent in these breezier areas. After coordinating with neighboring offices, the Red Flag Warning has been canceled. Satellite imagery reveals mostly clear skies, except some low coastal stratus extending into Santa Cruz County, and some higher clouds over portions of the the southern half of the district.

Dry weather will continue through the rest of the work week and through early next week. Overnight low temperatures are forecast to cool into the 30s to mid 40s during the weekend, coolest in the inland valleys. High temps will be mild, generally in the 60s.

A pattern shift is still looking probable next week. Models remain in relatively good agreement in bringing a cool upper level trough in from the northwest on Tuesday, with widespread rain developing by late that day. Shower chances to persist through midweek with the trough moving east by Friday.

AVIATION. as of 10:04 AM PST Thursday . For 18z TAFs. VFR continues at the TAF sites this morning. Southerly flow is bringing low clouds to Santa Cruz County and off the coast of Monterey and San Mateo Counties. VFR will continue through the afternoon with winds 5-10 kt. Offshore winds this morning will transition to west or southwest this afternoon. MVFR cigs will expand along the coastline this evening. Some low clouds could make their way into the San Francisco Bay terminals overnight tonight into Friday morning.

Vicinity of KSFO . VFR. North to northeast winds around 5 kt becoming light SW after 00Z. Some low clouds could begin to move over the terminal and approach late tonight into Friday morning but confidence on extent is low.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . E-SE winds around 5 kt at MRY and 5-10 kt in the Salinas Valley. Northwest winds at KSNS around 20-21z and southwest at KMRY around 20z. MVFR cigs expected to return this evening.

FIRE WEATHER. As of 3:17 AM PST Thursday . Gusty offshore winds in the hills of the North and East Bay have subsided overnight, but some gusts remain in the 30 to 40 mph range. Relative humidity values remain over 30 percent, however, so the Red Flag Warning has been canceled.

Fire weather concerns will return early next week as medium range models suggest another round of offshore flow impacting the region and be potentially more widespread. Hot dry windy index shows values increasing to nearly 400 by Monday. Stay tuned - fire season is definitely not over until the region receives widespread wetting rainfall.

MARINE. as of 09:06 AM PST Thursday . Low pressure over southern California will move slowly east. This will bring light east to southeast winds through Friday. Winds will switch to north to northwest late on Friday. A long-period northwest swell will build on Friday and continue through 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.
