Winds are reducing across the region but will remain breezy through much of Saturday. Gusts will be strongest directly along the coast, mountain gaps/passes, and across the higher terrain. Prefrontal moisture will lead to an increase in RH overnight as well as coastal drizzle and slight chances for light rain along the coast and in the bays. Additional slight chances for rain arrive along a passing cold front for the northernmost portions of the North Bay counties Saturday evening. Temperatures cool after the front passes leading to some improvement in humidities into Sunday. The pattern shifts into a ridge for the next work week, leading to a compressing marine layer and a steady warming trend. The increased warming and drying will lead to increasing fire concerns into the end of the work week. Note : All winds are 20-foot Winds Unless otherwise specified. Thunderstorms imply strong, gusty and erratic winds. ...Discussion from Los Angeles/Oxnard... ...LONG DURATION HEATWAVE WITH WIDESPREAD ELEVATED FIRE WEATHER CONDITIONS INCLUDING POTENTIAL FOR LARGE PLUME DOMINATED FIRES AWAY FROM THE COAST FROM NEXT TUESDAY THROUGH SUNDAY... An upper level trough over the region combined with strong onshore flow near the surface has deepened the marine layer to around 3000 feet this morning, bringing low clouds and fog into the lower coastal slopes. This has brought a cooling trend with improving fire weather conditions to much of the region through Sunday. However, there will still be some locally elevated fire weather conditions across the Antelope Valleys as onshore winds are expected to gust between 25 and 35 mph today, while humidities lower to between 10 and 20 percent. A long duration heat wave is becoming more likely next week from next Tuesday through Sunday. With onshore flow expected to be weaker with this event, heat impacts could potentially spread to inland portions of the coastal plain. The combination of hot temperatures and low humidities away from the coast will likely bring widespread elevated fire weather conditions across the valleys, mountains, and deserts, with an increased risk of large plume dominated fires, especially in the mountains and foothills. During the peak of the heatwave, which will likely be Thursday and Friday, temperatures could soar to between 98 and 108 degrees, minimum humidities could range between 8 and 20 percent, and mixing heights could rise to between 10,000 and 16,000 feet across the interior. The main wind concerns next week will be locally gusty and very warm sundowner winds across southwest Santa Barbara county, as well as northwest to north winds across the interior mountains, especially near the I-5 corridor. The main focus for these winds will likely be Monday through Thursday night. $$ ECC028-170900- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 754 AM PDT Sat Aug 16 2025 ...LONG DURATION HEATWAVE WITH WIDESPREAD ELEVATED FIRE WEATHER CONDITIONS INCLUDING POTENTIAL FOR LARGE PLUME DOMINATED FIRES AWAY FROM THE COAST FROM NEXT TUESDAY THROUGH SUNDAY...
