FNUS86 KLOX 232236 FWLLOX ECCDA Discussions National Weather Service Los Angeles/Oxnard CA 336 PM PDT Sun Aug 23 2026 ECC029-241645- Los Padres National Forest- Discussion for Vandenberg ECC Dispatch 336 PM PDT Sun Aug 23 2026 ...Discussion from Monterey... The marine layer remains compressed to around 1000 feet with fluctuations between 1000 to 1200 feet expected this week. There is a low (5%) chance of storms developing across northern Napa County early Monday morning due to the arrival of a weak shortwave trough. Confidence that storms will develop is low and any convective potential decreases by Monday afternoon. Coastal drizzle and patchy fog are likely directly along the coastline through the week. Slightly above normal temperatures and very dry conditions continue above the marine layer with poor daytime humidity values between 10-20%. Little to no humidity recovery is expected at the higher elevations with overnight RH values peaking between 20-30%. Diurnally breezy winds continue across favored locations through 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 TO LOCALLY BRIEF CRITICAL FIRE WEATHER CONDITIONS AWAY FROM THE IMMEDIATE COAST THROUGH NEXT WEEKEND WITH SIGNIFICANT RISK OF LARGE PLUME DOMINATED FIRES, PEAKING TUESDAY THROUGH SATURDAY DUE TO HOTTEST 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 97 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 in 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 to locally brief critical 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. This will maintain the threat for large plume dominated fires and rapid fire spread through next weekend. Gusty sundowner winds will likely affect southwest Santa Barbara County the next couple evenings, potentially becoming slightly stronger/widespread with hotter/drier conditions on Tuesday evening and Saturday evening. This will likely bring brief critical fire weather conditions at times from Tuesday evening to Saturday night across Southern Santa Barbara county as well as the I-5 corridor in the LA county mountains, and Highway 33 corridor in Ventura county mountains. There is 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. $$ ECC028-241645- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 336 PM PDT Sun Aug 23 2026 ...WIDESPREAD ELEVATED TO LOCALLY BRIEF CRITICAL FIRE WEATHER CONDITIONS AWAY FROM THE IMMEDIATE COAST THROUGH NEXT WEEKEND WITH SIGNIFICANT RISK OF LARGE PLUME DOMINATED FIRES, PEAKING TUESDAY THROUGH SATURDAY DUE TO HOTTEST 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...
