A compressed marine layer will bring below normal temperatures, morning and evening clouds, and a chance for drizzle to coastal locations. Inland and above the marine layer, slightly above normal temperatures and dry conditions persist. Poor minimum daytime relative humidity in the afternoons with little to no recovery at night will continue in the higher elevations. Diurnal winds are expected. Similar conditions are expected into the upcoming week. Note : All winds are 20-foot Winds Unless otherwise specified. Thunderstorms imply strong, gusty and erratic winds. ...Discussion from Los Angeles/Oxnard... ...WIDESPREAD ELEVATED FIRE WEATHER CONDITIONS AWAY FROM THE IMMEDIATE COAST THROUGH NEXT WEEKEND WITH INCREASED RISK OF LARGE PLUME DOMINATED FIRES, PEAKING TUESDAY THROUGH FRIDAY DUE TO HOTTER TEMPERATURES AND DEEPER MIXING HEIGHTS... ...ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS ACROSS SOUTHERN SANTA BARBARA COUNTY DURING LATE AFTERNOON AND EVENING HOURS FROM TODAY THROUGH SATURDAY NIGHT DUE TO GUSTY SUNDOWNER WINDS WITH HOT AND DRY CONDITIONS... Hot and dry conditions will continue through Monday with temperatures between 95 and 107 degrees common over most valleys, mountains, and deserts. These temperatures will likely bump up slightly from Tuesday through at least Friday, especially across the valleys and interior coastal plain as weak offshore pressure trends are likely to develop. During the peak of the heat during this time frame, we can expected widespread temperatures of 100 to 110 degrees across the valleys, lower mountains and deserts. This will likely translate into expansion of widespread elevated fire weather conditions over these areas. Minimum humidities will lower to between 10 and 25 percent each day away from the coast. Meanwhile, mixing heights will likely range between 10,000 and 17,000 feet across the interior each afternoon, potentially climbing as high as 18,000 feet during the peak of the heat Tuesday through Friday. This will maintain the threat for large plume dominated fires and rapid fire spread through the week. Gusty sundowner winds will likely affect southwest Santa Barbara County the next couple evenings, potentially becoming slightly stronger/widespread with hotter/drier conditions by Tuesday and Wednesday evenings. This will likely bring brief critical fire weather conditions at times to Southern Santa Barbara county and possibly the I-5 corridor between Tuesday evening and Saturday night, with a 20-30 percent chance of Red Flag durations during this time. Also, there will likely be a slight influx of mid level moisture on Monday which could bring a 5-10 percent chance of thunderstorms across eastern San Gabriel mountains and eastern Antelope Valley, with isolated dry lightning strikes the main threat. $$ ECC028-241045- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 942 AM PDT Sun Aug 23 2026 ...WIDESPREAD ELEVATED FIRE WEATHER CONDITIONS AWAY FROM THE IMMEDIATE COAST THROUGH NEXT WEEKEND WITH INCREASED RISK OF LARGE PLUME DOMINATED FIRES, PEAKING TUESDAY THROUGH FRIDAY DUE TO HOTTER TEMPERATURES AND DEEPER MIXING HEIGHTS... ...ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS ACROSS SOUTHERN SANTA BARBARA COUNTY DURING LATE AFTERNOON AND EVENING HOURS FROM TODAY THROUGH SATURDAY NIGHT DUE TO GUSTY SUNDOWNER WINDS WITH HOT AND DRY CONDITIONS...
