801 FXUS66 KHNX 280814 AFDHNX Area Forecast Discussion National Weather Service Hanford CA 1214 AM PST Fri Nov 28 2025 && .KEY MESSAGES... 1. Dense Fog Advisory in effect through 10 AM Friday. Fog expected again late Friday into Saturday morning. 2. A trough slides to the east on late Saturday through Tuesday. It will be dry but wind gusts will pick up. 3. The next best chance of rain is late Tuesday into Thursday with a second trough. && .DISCUSSION... Thanksgiving was a day to give thanks as the stratus finally broke in parts of the Valley. However, fog has begun or started to show up on imagery in the southern Valley as of midnight. A Dense Fog Advisory has been issued through 10 AM due to high confidence of visibilities less than 1/4 mile. However, with the ridge of high pressure weakening today as a shortwave rides through the Pacific Northwest, the fog should be easier to clear allowing temperatures to climb. There is a 60 to 95 percent chance in the NBM of highs of at least 60 degrees in the Valley today. Model ensembles have a better agreement of this weekend as a cutoff low slides under the ridge through Saturday before making a right turn and hanging over the Pacific. At the same time, another trough begins sliding from the Pacific Northwest late Saturday to the Great Basin by Monday. However, the ensembles diverge as to how far east in the Basin the trough will be. No precipitation is expected from either troughs. Tuesday through Thursday brings a third trough which the ensembles agree takes an inside slider approach over the Sierra Nevada. However, there is a 25 percent chance or less of any precipitation on Wednesday and Thursday for the Valley with this system. Snow probabilities are also low at 25 to 40 percent chance of any accumulation above 7,000 feet. && .AVIATION... IFR to MVFR ceilings and visibilities will persist in most Valley locations through 18Z Friday. After 18Z, conditions will improve especially after 20Z. However, MVFR to IFR conditions return between 6Z and 9Z Saturday for the overnight hours. && .AIR QUALITY ISSUES...
