Hazardous heat will continue across the Southern Plains, Gulf Coast and Desert Southwest through the weekend. Additional heat will build into the Great Basin and Northern Plains this weekend. A stalled front is expected to bring periods of heavy to excessive rainfall and flooding from the Tennessee Valley to the Southeast U.S on Friday. Read More >

797 FXUS66 KMTR 240524 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 1024 PM PDT Thu Jul 23 2026 ...New AVIATION, MARINE... .KEY MESSAGES... Updated at 114 PM PDT Thu Jul 23 2026 - Breezy onshore winds expected each afternoon and evening through the weekend - Temperatures near seasonal averages throughout early next week && .SHORT TERM... Issued at 114 PM PDT Thu Jul 23 2026 (This evening through Friday night) Stratus continues to retreat to the coast this afternoon with sunny sky conditions returning to the interior. Thus, temperatures are forecast to reach the low 60s to middle 70s near the coast, 70s to lower 80s bayside, and 80s to lower 90s across the interior valleys. The southern portion of the Central Coast has the greatest potential to exceed 100 deg F in places such as Lockwood, Bradley and Parkfield. For tonight, stratus looks to return back to the coast late this evening and fill locally inland into the coastal adjacent valleys. However, the pattern aloft looks to be the same as this morning, so expect some disruptions in the cloud deck at times. Patch fog is also likely along the coast and in the Russian River Valley. Friday is looking like a repeat of today`s afternoon temperatures. The noteworthy thing to mention is the high level clouds forecast by late Friday afternoon/evening. This is a result of monsoon moisture advecting northward around the mid/upper level high pressure over the Four Corners Region. However, the moisture will be high enough aloft to just produce high level clouds. && .LONG TERM... Issued at 114 PM PDT Thu Jul 23 2026 (Saturday through next Wednesday) The ridge over the Southwest is continuing to shift towards to Four Corners and will build in strengthen over the weekend. Meanwhile, the mid/upper level trough off of the Pacific Northwest coast will also strengthen. This will keep a shallow marine layer in place while also allowing for a slight warming trend across the interior into early next week. Additionally, this will work the keep the high pressure over the Four Corners/Southwest region. Still expecting typical ebb and flow of stratus returning to the coast late in the evening and into the valleys overnight. Stratus will retreat to the coast by mid-to-late morning each day. Looking at the 8-14 day Temperature Outlook from the Climate Prediction Center, we are likely to see above average temperatures across the region with the high pressure shifting further westward across southern California. && .AVIATION... (06Z TAFS) Issued at 1013 PM PDT Thu Jul 23 2026 Stratus coverage is limited attm and mostly confined to the coast line. Short term guidance indicates an expectation that all terminals will drop to at least MVFR with Monterey Bay terminals and KSTS dropping to IFR by sunrise. Given current satellite trends decided to keep South Bay terminals VFR through the forecast period. Vicinity of SFO...Currently VFR with low confidence in timing of MVFR ceilings spreading over the terminals. Once at MVFR, clearing times should be by late morning with KOAK first followed by KSFO an hour later as stratus retreats back to the coast under a compressed marine layer. SFO Bridge Approach...Similar to SFO. Monterey Bay Terminals...VFR, with limited coverage of stratus attm despite a ceiling earlier in the evening at KMRY. Stratus is forming on the lee side of the peninsula as wind blows from north to south without much back building into the Bay. Short term guidance is confident that MVFR then IFR ceilings will develop, will have to continue to monitor satellite trends. Clearing is expected by early afternoon at the latest with VFR through the remainder of the afternoon and early evening. && .MARINE... (Tonight through next Wednesday) Issued at 1013 PM PDT Thu Jul 23 2026 Moderate to fresh northwest breezes with strong gusts will continue into the weekend, with moderate wind driven seas. Hurricane Fausto will produce long period south to southwest swell that persist into the beginning of next week. && .BEACHES... Issued at 114 PM PDT Thu Jul 23 2026 Hurricane Fausto in the tropical Eastern Pacific will generate a long period southwesterly swell which is forecast to reach the coastline of the San Francisco Bay Area and Central Coast this upcoming weekend. As such, sneaker waves and strong rip currents are the primary concerns. However, breaking waves can reach up to 10 feet along some south and southwest facing beaches and break points (like Santa Cruz, Pacifica, and parts of Stinson or Ocean Beach). Sneaker waves can have 20+ minutes in between the larger sets (breaking waves) with significant "flat/calm looking" times between them. This can potentially catching beachgoers by surprise and resulting in people being swept into the cold water; hence the name "sneaker". Rip currents are strong enough to pull the strongest swimmers away from shore. Swim near a lifeguard if possible. Stay back from the beach, and away from jetties, piers, beachside rocks, and other infrastructure near the water. Never turn your back to the ocean! A Beach Hazards Statement is in effect from Saturday morning through Tuesday afternoon for all beaches along the Pacific Coast. RGass && .MTR WATCHES/WARNINGS/ADVISORIES... CA...Beach Hazards Statement from Saturday morning through Tuesday afternoon for CAZ006-505-509-529-530. PZ...Small Craft Advisory until 9 PM PDT Friday for Mry Bay.
