778 FXUS66 KSTO 241846 AFDSTO Area Forecast Discussion National Weather Service Sacramento CA 1146 AM PDT Sat Oct 24 2026 .KEY MESSAGES... - Dry weather continues through most of next week, chance for light showers over the Shasta County mountains on Monday - Breezy to gusty onshore winds on Monday, strongest in the mountains - Potential for unsettled weather Halloween Weekend, but details remain uncertain .DISCUSSION... ...Today through Monday... Mostly clear skies today, following the rain and cloudy weather we experienced the last couple of days. Winds will steadily decrease today, with downsloping northeast to east winds lingering in the mountains through this evening, up to 15 to 25 mph at times. Given the timing of the winds, cooler temperatures, and the recent rainfall, no widespread fire weather concerns are anticipated at this time. However, as northerly winds decrease, there is a 5 to 20% chance of fog development in the Valley overnight tonight; highest chances in the northern San Joaquin Valley. Ridging will keep the high temperatures in the high 60s to low 70s through Monday, with a slight downward trend beginning Monday as a weather system passes through the area. This system will also bring low chances for light precipitation in Shasta County, particularly over the Coast Range and southern Cascades, as well as breezy onshore southerly winds. Strongest winds expected over the Sierra and southern Cascades, generally 20 to 30 mph, but up to 40 mph over peaks. Otherwise dry weather is expected across the remainder of interior NorCal. ...Tuesday and Beyond... Dry weather continues through the majority of the work week, but potential remains for unsettled weather at the end of October and into early November. Ensemble guidance seems clear now that a low pressure system will approach the area, but details about precipitation amounts and impacts remain fairly uncertain this far out. Regardless, this week will be an ideal time to clear gutters and secure loose outdoor decorations and items in preparation for any additional precipitation and gusty winds. && .AVIATION... Predominantly VFR conditions are expected over the next 24 hours. North to east winds decrease today, becoming less than 12 kts by 00Z Sunday. Potential for isolated FG/BR in the Valley from 11Z-16Z Sunday. Increasing mid to high level clouds ahead of a weak system tonight into Sunday. && .STO WATCHES/WARNINGS/ADVISORIES... None. && $$
