Area Forecast Discussion National Weather Service San Francisco CA 1208 AM PDT Wed May 15 2024

New SHORT TERM, LONG TERM

SYNOPSIS
Issued at 115 PM PDT Tue May 14 2024

Relatively calm and quiet weather pattern persists through the forecast period bringing a repeat of morning marine stratus along the coast and valleys and clear skies elsewhere. Inland temperatures warm into the 70s and 80s each afternoon with a persistent marine layer keeping coastal highs in the 60s.

SHORT TERM
(Today and tonight)
Issued at 1206 AM PDT Wed May 15 2024

High pressure over the northeast Pacific will nudge a bit closer to the Bay Area and Central Coast as low pressure aloft weakens over northern Baja. The marine layer remains rather consistent early this morning in the 1.5-2 kft range, which is similar to yesterday. With slightly greater influence from the ridge expect the top of the marine temperature inversion to either hold steady or compress a bit over the next 24 hours. Regardless, there are no real meaningful changes to the forecast. Expect morning clouds to gradually retreat back towards the coast by early afternoon with sun returning for most areas. This will allow high temperatures to reach the 70s and 80s inland, with 60s for the immediate coast and bays. Low stratus clouds will spread back inland this evening with mostly cloudy conditions returning overnight. Lows will be mostly in the lower to mid 50s.

LONG TERM
(Thursday through Tuesday)
Issued at 1206 AM PDT Wed May 15 2024

The upper level ridge will gain slight prominence through Thursday, however we will remain along its periphery with a minimal increase in temperatures inland. Readings will range from the 60s along the coast to the upper 80s for the warmest inland valleys. A few hot spots may crack the 90 degree mark. Lows will be mostly in the 50s. The daily ebb and flow of coastal clouds will continue, with coverage spreading inland each night with a gradual retreat towards the coast by afternoon. The upper level pattern may transition more towards troughing by early next week but dry weather still looks to be the most probable forecast outcome.

AVIATION
(06Z TAFS)
Issued at 1046 PM PDT Tue May 14 2024

Currently seeing a mix of LIFR-VFR at the terminals. With the exception of LVK, LIFR-MVFR stratus will impact all terminals overnight. Widespread VFR and breezy onshore flow will prevail by tomorrow afternoon. LIFR-MVFR stratus looks to make a return to MRY, OAK, SFO, and SNS towards the end of the respective TAF periods.

Vicinity of SFO...Currently VFR with breezy northwesterly flow. An IFR ceiling will impact the terminal overnight before VFR prevails by the afternoon. Winds will remain onshore and breezy through the TAF period. A low-end MVFR-high-end IFR ceiling is likely to return towards the end of the TAF period.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently IFR with westerly flow at MRY and IFR with northwesterly flow at SNS. Ceilings are expected to further deteriorate to LIFR. VFR will prevail by tomorrow afternoon with MRY deteriorating to LIFR and SNS deteriorating to IFR by tomorrow evening. Winds will remain onshore through the TAF period.

MARINE
(Tonight through next Monday)
Issued at 1046 PM PDT Tue May 14 2024

Rough seas continue to diminish through Wednesday as the pressure gradient slackens and winds decrease. A moderate NW swell will continue to keep significant wave heights elevated, bordering on hazardous for small craft, in the far NW coastal zone. Otherwise, favorable conditions will continue into the weekend, with stronger NW winds expected next week.

MTR WATCHES/WARNINGS/ADVISORIES
CA...None.
PZ...None.
