940 FXUS66 KHNX 021046 AFDHNX Area Forecast Discussion National Weather Service Hanford CA 246 AM PST Tue Dec 2 2025 .KEY MESSAGES... 1. Afternoon clearing has lead to fog development overnight into this morning across the San Joaquin Valley. 2. A dry disturbance will introduce increasing winds across the deserts and mountain peaks from Wednesday into Thursday. && .DISCUSSION... Tule Fog may make its return tonight into tomorrow morning due to the clearing of the stratus this afternoon and the lingering moisture in the atmosphere near the surface of the Valley. A Dense Fog Advisory has been issued for the majority of the Valley from 11 PM tonight through 11 AM tomorrow morning. Take caution while driving and slow down, especially on the highways and state routes as vehicles may be difficult to see in the fog. This fog potential is expected to return by Friday if the stratus that formed last week makes an appearance again. A system is then expected to move through the Great Basin Wednesday into Thursday, which may bring strong winds to the desert and mountain peaks during that time. This system is not expected to cause any precipitation, due to the fact that it will be moving out of western Canada and not offshore where it would otherwise pick up some marine air. The dry pattern is expected to continue through the weekend as a ridge builds in from the Pacific. && .AVIATION... IFR/LIFR visibilities are expected at all TAF sites until 20Z Tuesday. Between 12Z and 19Z Tuesday, VLIFR conditions have a 50% to 70% chance of occurring in dense fog.
