Area Forecast Discussion National Weather Service San Francisco Bay Area 445 AM PDT Tue Jul 14 2020

SYNOPSIS. A few additional degrees of inland cooling is expected on Tuesday as onshore flow increases. Temperatures will then likely remain near seasonal averages for the remainder of the week and into the upcoming weekend along with the ebb and flow of overnight and morning low clouds.

DISCUSSION. as of 03:24 AM PDT Tuesday . As high pressure over the Desert Southwest continues to weaken, onshore flow continues to push marine air well inland with current temperatures across the interior a few to as much as 10 deg F cooler compared to this time yesterday. Additionally, widespread stratus has penetrated inland in response to a the marine layer now more than 2,000 feet in depth per the Fort Ord Profiler. Meanwhile, locations such as the Sonoma Valley, much of the South Bay and interior East Bay Valleys remain clear at this time.

Surface winds along the coast are forecast to turn southerly throughout the day which should result in a cooling trend in locations such as Santa Rosa, Santa Cruz and Big Sur. Meanwhile interior locations will see temperatures today to be similar to or slightly cooler compared to yesterday. Similar conditions are likely to persist into Wednesday with temperatures near to slightly below seasonal averages along with the ebb and flow of coastal stratus into the valleys during the overnight/morning hours.

Another upper level trough is forecast to develop near the West Coast by late week resulting in only minor day to day fluctuations in temperatures, especially near the coast. Meanwhile, some slight warming will be possible across the interior as onshore flow weakens slightly. While the forecast models indicate a slight increase in mid/upper level monsoon moisture advecting across the Sierra by Thursday, it appears the deepest moisture and most instability will remain to the east of the Bay Area. Thus, cannot rule out a few higher level clouds drifting westward across the region late in the week. Overall, weather conditions through the upcoming weekend will be typical of mid/late July.

AVIATION. as of 4:45 AM PDT Tuesday . Marine layer has deepened to over 2000 ft. Stratus moved into the East Bay early last night but a weak circulation off the San Mateo coast has produced a southerly flow that is keeping stratus out of SFO. Southerly winds are stronger than normal at SJC this morning. Conditions are expected to remain VFR at SFO but some stratus from the East Bay may move over the parts of the approach. Clouds in the Bay Area clearing after 17Z.

Vicinity of KSFO . VFR with cigs at OAK and parts of the approach. Southwest winds 5-10 kt this morning becoming west to northwest 10-15 kt after 20Z.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . Cigs at or just below 1000 ft this morning. A deep marine layer may keep clouds in for most of the day at MRY. Clearing after 20-21Z at SNS returning early in the evening.

MARINE. as of 04:32 AM PDT Tuesday . A weak low pressure circulation off the San Mateo coast is bringing a light southerly flow to the inner waters and stronger northwest winds to the outer waters. Winds will increase over the northern San Francisco Bay during the afternoon and evening hours. This pattern is expected to continue through Thursday.

MTR WATCHES/WARNINGS/ADVISORIES. Tday. SCA . Pt Arena to Pigeon Pt 10-60 nm SCA . Pt Arena to Pt Reyes 0-10 nm until 6 AM SCA . SF Bay from 11 AM

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.
