896 FXUS66 KSTO 062110 AFDSTO Area Forecast Discussion National Weather Service Sacramento CA 110 PM PST Sat Dec 6 2025 .KEY MESSAGES... - Periods of low clouds, mist, or fog continue in the Central Valley for the next few mornings - Seasonable temperatures and light winds are forecast over the next several days && .DISCUSSION... ...Today - Sunday... Stratus/Low clouds were more of the story this morning vs. fog dominating the forecast yesterday but still impacting much of the Central Valley and adjacent lower foothills. Out forecast remains on repeat with another round of low clouds/fog tonight into tomorrow morning with best chances Sacramento northward although fog is possible throughout all of the Valley. Dry weather and seasonable temperatures are forecasted for the region, with upper 40s to 50s in the Valley and foothills, and 40s to 60s in the mountains for the daytime highs. Highs are trending several degrees cooler than initially forecasted due to the persistence of the fog/low clouds, keeping max temperatures from being fully actualized. ...Next Week... High pressure builds across the region next week, allowing for a gradual warming trend with high temperatures warming to the 50s to near 70 (mainly for areas outside of stratus/fog development). Dry conditions will continue through next week. Some ensembles are indicating a weak pattern change in mid December but there is a large amount of uncertainty as it is too far out in time. && .AVIATION... Lingering low cigs and mist across the Central Valley continues into this evening, although some sites may very briefly return to VFR conditions around 22-24Z. Another round of BF/FG and low stratus returns tonight after 03Z and continues through Sunday, with areas of MVFR/IFR conditions.
