Below normal temperatures continue through Thursday before a warming trend, bringing back seasonal highs, begins Friday into the weekend. High pressure will build across the West Coast this weekend with the marine layer compressing to around 1000-1200 ft this weekend. Good overnight recoveries and fair daytime humidity retention continues for locations within the marine layer. Localized elevated fire weather concerns continue for the higher elevations above the marine layer where poor to fair overnight recoveries and poor daytime humidity retention continues. Further drying is expected across the higher elevations Saturday into next week with daytime humidity values dropping to between 15% to 25%. Note : All winds are 20-foot Winds Unless otherwise specified. Thunderstorms imply strong, gusty and erratic winds. ...Discussion from Los Angeles/Oxnard... ...ELEVATED FIRE WEATHER CONDITIONS ACROSS SOME INTERIOR VALLEYS, MOUNTAINS, AND DESERTS TODAY... ...SLIGHT CHANCE OF THUNDERSTORMS THURSDAY THROUGH SUNDAY FOCUSED OVER THE SAN GABRIEL MOUNTAINS AND ANTELOPE VALLEY... Elevated fire weather (breezy winds and low humidity) conditions will continue across some interior valleys, mountains, and deserts through this evening. There is an increased risk of large grass fires with rapid fire spread, especially for the Antelope Valley and Highway 14 Corridor. A deep marine layer through at least Thursday will maintain below normal risk for large fire for coasts, coastal valleys, extending into some interior valleys (mainly San Luis Obispo County). The marine layer will likely shrink especially north of Point Conception through the weekend, leading to warming and drying trends focused across interior valleys of San Luis Obispo and Santa Barbara Counties. There is a 15-25 percent chance of monsoonal showers and thunderstorms peaking Thursday through Friday including the overnight hours focused across the Los Angeles County, but potentially spreading west into at least Ventura County at times as well. The greatest threat is over the mountains, but there is a 5-15 percent chance of occuring in the coastal valleys to coast especially in the early morning hours Friday. The threat of thunderstorms may linger in the weekend, especially across eastern Los Angeles County. New fire starts from dry lighting, damaging winds, and localized flooding are possible with any monsoon thunderstorms. There is a 20 percent chance that the monsoon disrupts the marine layer, especially for LA County, leading to the significant warming trends near the coast. $$ ECC028-171700- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 346 PM PDT Wed Jul 16 2025 ...ELEVATED FIRE WEATHER CONDITIONS ACROSS SOME INTERIOR VALLEYS, MOUNTAINS, AND DESERTS TODAY... ...SLIGHT CHANCE OF THUNDERSTORMS THURSDAY THROUGH SUNDAY FOCUSED OVER THE SAN GABRIEL MOUNTAINS AND ANTELOPE VALLEY...
