Localized, elevated fire weather conditions continue across the elevated terrain above the marine layer (above 2000-2500 feet). Minimal fire weather concerns continue within the marine layer with good overnight recoveries and poor to fair daytime humidity retention between 30% to 45% continuing within the interior. Poor to fair overnight recoveries are expected above 2000 ft with poor daytime humidity retention between 15% to 25%. Locally breezy onshore winds to around 25 mph continue within mountain gaps/passes, along the coast, and within the Salinas Valley. Temperatures warm to seasonal to slightly above normal temperatures starting Wednesday through the extended forecast. Note : All winds are 20-foot Winds Unless otherwise specified. Thunderstorms imply strong, gusty and erratic winds. ...Discussion from Los Angeles/Oxnard... ...EXTENDED HEAT WAVE WITH WIDESPREAD ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS ACROSS INTERIOR TODAY INTO EARLY NEXT WEEK, WITH SMALL RISK OF MONSOONAL THUNDERSTORMS ACROSS MOUNTAINS AND DESERTS... High confidence in a heat wave impacting the area starting today and lasting through Friday across the valleys, mountains, and deserts. This heat wave will likely extend into early next week across the interior areas, especially the Antelope Valley. Temperatures will peak across most areas Wednesday and Thursday, and possibly again early next week. During the peak, high temperatures between 95 and 105 are looking like the most likely outcome for most lower mountains, valleys (including coastal valleys), and deserts. Deeper mixing heights of 10,000 to 15,000 feet will increase the risk for large plume dominated fires Wednesday into early next week, especially in the mountains. Minimum humidities of 6 to 20 percent are expected in the interior valleys, mountains, and deserts during the heat wave, with poor humidity recoveries in the mountains. There is also a 5% chance of monsoonal thunderstorms over the mountains and deserts on Tuesday and Wednesday, increasing to 10% chance by next Tuesday and Wednesday (July 15-16). Southwest to northwest winds of 15 to 25 mph with gusts to 35 mph (except isolated gusts to 40 mph western Antelope Valley foothills) will continue each afternoon/evening over the typical wind prone interior areas, increasing to gusts of 30 to 45 mph from Friday through Monday when there will likely be stronger and more widespread onshore flow. The strongest onshore winds will likely be focused across the interior, especially Antelope Valley and adjacent foothills, along with the Highway 14 corridor, and San Luis Obispo Interior Valleys (especially Friday through Monday). In addition, there will likely be gusty warm and dry sundowner winds causing elevated fire weather conditions in southwest Santa Barbara county each evening today through Thursday, mainly from Gaviota to San Marcos Pass. These areas could see wind gusts of 25 to 40 mph with isolated gusts to around 45 mph near Gaviota. Humidities are expected to lower to between 20 and 40 percent with the gusty sundowner winds. All of this adds up to widespread elevated to brief critical fire weather scenario today through early next week across the interior as well as southwest Santa Barbara county. While the chance of reaching classic Red Flag Warning criteria remains low this upcoming week, considering recent fire behavior and the increased risk for plume dominated fires and gusty sundowner winds, there is a 20 percent chance of Red Flag Warning issuance this week into early next week. There is still a 20-40 percent chance of Heat Advisories being issued for interior areas at some point this week, with a 10-20 percent chance of Heat Warning for the Antelope Valley. $$ ECC028-091630- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 324 PM PDT Tue Jul 8 2025 ...EXTENDED HEAT WAVE WITH WIDESPREAD ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS ACROSS INTERIOR TODAY INTO EARLY NEXT WEEK, WITH SMALL RISK OF MONSOONAL THUNDERSTORMS ACROSS MOUNTAINS AND DESERTS...
