Quiet weather returns, with a gradual cooling and drying trend forecast. This should lead to a deepening marine layer over the next few days, meaning stratus should infiltrate inland a bit more each night and there may be coastal drizzle at times. Clouds should retreat to the coast for the day and we may see onshore winds uptick during the afternoon and early evening hours, especially favoring valleys, gaps, and exposed ridges. Note : All winds are 20-foot Winds Unless otherwise specified. Thunderstorms imply strong, gusty and erratic winds. ...Discussion from Los Angeles/Oxnard... ...THUNDERSTORMS POSSIBLE IN THE AFTERNOONS THROUGH THURSDAY, FOCUSED ACROSS THE LA/VENTURA MOUNTAINS AND ANTELOPE VALLEY... This afternoon and again Thursday, there is a slight chance of monsoonal shower and thunderstorm activity across the mountains and deserts of LA and Ventura Counties. If a storm were to develop, hazards may include gusty downburst/outflow winds, lightning, and brief heavy rainfall. The highest threat for flash flooding and debris flows will be in the San Gabriel mountains and Antelope Valley where a flood watch is in effect, although chances of storms have trended down today, and the watch may be expired early. Warm to hot temperatures will persist today, with warmer temperatures occurring near the coast today due to weakening onshore flow. The Heat Advisory has been extended through this evening for the coasts and valleys of LA and Ventura Counties. Expect high temperatures of 80 to 90 at the beaches, 88 to 95 across the inland coasts, and 94 to 102 across the valleys, foothills, and deserts. Hot temperatures combined with instability will result in moderately deep mixing heights between 10,000 and 14,000 feet this afternoon. As a result, there is an elevated risk for large plume dominated fires across the interior. Humidities between 18 and 30 percent for the warmest valleys, lower mountains, and deserts today and tomorrow due to an influx of monsoonal moistures. $$ ECC028-041045- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 934 AM PDT Wed Sep 3 2025 ...THUNDERSTORMS POSSIBLE IN THE AFTERNOONS THROUGH THURSDAY, FOCUSED ACROSS THE LA/VENTURA MOUNTAINS AND ANTELOPE VALLEY...
