The next blast of Arctic air surges south down the Plains, across the Great Lakes and through the Southeast and East Friday through Saturday. This could be longest duration of cold in several decades. Forecast models are being closely monitored for potential of another significant winter storm to impact the eastern United States this coming weekend. Confidence in coastal impacts has increased.

741 FXUS66 KMTR 282140 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 140 PM PST Wed Jan 28 2026 ...New SHORT TERM, LONG TERM... .KEY MESSAGES... Updated at 136 PM PST Wed Jan 28 2026 - Beach Hazards Statement for increased risk of sneaker waves Wednesday night through Friday morning - Minor King Tide coastal flooding Friday through Sunday - Warm, dry weather and weak offshore flow continues into the weekend && .SHORT TERM... Issued at 136 PM PST Wed Jan 28 2026 (This evening through Thursday) Dry weather has returned to the region with ridging rebuilding over the West Coast. Patchy fog returns tonight across the North Bay and East Bay Valleys with locally dense fog possible along the bay shoreline. Morning low temperatures will remain chilly, particularly across the North Bay Valleys and interior Central Coast. Low temperatures will be in the 40s for most locations with the chilliest spots in the mid to upper 30s. High temperatures on Thursday will warm slightly compared to today. Most interior locations will be in the mid to upper 60s with portions of the Salinas Valley reaching the upper 60s to low 70s. The exception will be the North Bay and East Bay Valleys where fog will keep temperatures cooler and see high temperatures in the upper 50s to mid 60s. Light offshore flow continues through the short term and into the long term forecast with no major changes. && .LONG TERM... Issued at 136 PM PST Wed Jan 28 2026 (Thursday night through next Tuesday) Warmer and drier weather continues through at least Saturday with the potential for some light rain/drizzle across the North Bay Sunday night into Monday. Upper level ridging persists through Saturday when a shortwave trough reaches the West Coast and forces the ridge to exit eastward. Shortwave troughing will be short lived given its progressive nature and it will exit our area by early Monday morning. Ridging rebuilds by late Monday and remains entrenched over our area through the rest (and arguably past the end) of the long term forecast. Temperatures will be running between 5 to 15 degrees above normal this week with the warmest temperatures in the interior Central Coast. Friday and Saturday will be the two warmest days with highs in the low to mid 70s across the interior Central Coast, portions of the Santa Clara Valley, and the Santa Cruz Mountains. Everywhere else will stay in the 60s. Temperatures cool, becoming more seasonal, Sunday and Monday as shortwave troughing moves through. High temperatures will drop down into the upper 50s to mid 60s across the Bay Area and Central Coast. The cool down will be short lived with above normal temperatures in the mid 60s to low 70s returning Tuesday and Wednesday. Light rain/drizzle is possible across the North Bay Sunday night into Monday as the shortwave trough moves through. Unfortunately for rain lovers, only a few hundredths of an inch is expected and it looks to be limited to the North Bay Coastal Mountains. Models are trying to show deep upper level troughing returning to the West Coast around mid- February but confidence is low at this time. Minor coastal flooding is possible along the SF Bay Shoreline Friday, Saturday, and Sunday. This will primarily effect low lying areas directly along the bay shoreline and is not expected to be as widespread as it was earlier this month. If your commute takes you directly along the bay shoreline, be prepared for potential impacts to your drive and local road/parking lot closures. A Beach Hazards Statement goes into effect at 9PM tonight and remains in effect through 9AM Friday morning. For more information see the Beaches section below. && .AVIATION... (18Z TAFS) Issued at 937 AM PST Wed Jan 28 2026 VFR conditions expected to persist through much of the forecast period. Light offshore flow this morning is forecast to return to onshore by this afternoon and persist through the evening. High clouds will continue to pass over the region. Overnight, winds will become light and variable at times with the greatest potential for fog development over the North Bay valleys early Thursday morning. Where fog and/or low ceilings develop, expect clearing by around 18Z Thursday. Vicinity of SFO...VFR. Light offshore winds this morning will become onshore by this afternoon. High confidence of VFR conditions to persist through the TAF period. SFO Bridge Approach...Similar to SFO. Monterey Bay Terminals...VFR. Light southerly winds this morning will become onshore by this afternoon. High confidence of VFR conditions to persist through the TAF period. && .MARINE... (Today through Monday) Issued at 900 AM PST Wed Jan 28 2026 Gentle to moderate northerly/offshore breezes will prevail through Friday before winds veer to become southerly over the weekend. Moderate seas will build to become rough for the inner waters and outer waters today with very rough seas expected Thursday for the northern waters. && .BEACHES... Issued at 347 AM PST Wed Jan 28 2026 Hazardous beach conditions return to all Pacific Coast beaches tonight and persist through Friday morning. Long period westerly swell will bring an increased risk for sneaker waves and strong rip currents with breaking waves of 14 to 19 feet. Remember: stay off of jetties, piers, rocks, and other waterside infrastructure, remain out of the water to avoid hazardous surf, and never turn your back on the ocean! && .MTR WATCHES/WARNINGS/ADVISORIES... CA...Beach Hazards Statement from 9 PM PST this evening through Friday morning for CAZ006-505-509-529-530. PZ...Small Craft Advisory from 9 AM Thursday to 3 AM PST Friday for Pigeon Pt to Pt Pinos 10-60 NM-Pt Arena to Pt Reyes 0-10 nm.
