489 FXUS66 KHNX 010030 AFDHNX Area Forecast Discussion National Weather Service Hanford CA 430 PM PST Sun Nov 30 2025 .UPDATE... Updates Aviation and Air Quality Issues Sections. && .KEY MESSAGES... 1. Stratus will continue to hang around through most of Sunday. 2. Trough slides to the east through Tuesday. Winds increase but will bring no precipitation to the area. 3. A second trough slides down Tuesday through Thursday. Precipitation chances increase for this trough. && .DISCUSSION... Stratus has continued to hang around which kept temperatures cold again yesterday. However, ensembles show the ridge crumbling and breaking as two troughs are in play. One of them becomes a cutoff low later today but will spin offshore and move away towards Hawaii. However, the other trough we have been keeping an eye on will also begin sliding in later today through the weekend. This trough will help increase wind gusts by a few miles per hour but not to Advisory level or cause Mono winds for our area. This trough moves east quickly and will not bring any rain or snow to our area. The next chance of rain and snow is another trough which slides down late Tuesday through Thursday. However, models diverge around Thursday as to whether this trough will become a cutoff low or move east. Latest probabilities have a 5 percent chance or less of an inch of snow in the Sierra Nevada with this storm and a 20 to 25 percent chance of any rain accumulating in the Valley Thursday into Friday. && .AVIATION... IFR to MVFR ceilings and visibilities will persist in most Valley locations through 18Z Monday.
