Shallow and compressed marine layer remain along the coast and locally inland. Onshore flow will remain today leading to cool temperatures, moderate humidity, and breezy to gusty conditions. Winds will be strong for the higher terrain and interior gaps/passes. Gusts 40-50 mph will be possible for the windiest locations, especially the East Bay. Cool onshore flow remains for the weekend as well. 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 WITH THREAT OF LARGE PLUME DOMINATED FIRES NEXT TUESDAY THROUGH FRIDAY (JULY 8-11) ALONG WITH SMALL RISK OF MONSOONAL THUNDERSTORMS... Minor warming and drying expected each day through Monday. Over the interior areas, highs between 88 and 98 will be common, with minimum humidities between 10 and 20 percent. Pockets of humidities down to 5 to 10 percent are likely in the deserts and higher peaks, especially over the weekend. Southwest to northwest winds 15 to 25 mph with gusts to 35 mph will be common over the interior valleys and mountains, with isolated gusts up to 40 mph in the Antelope Valley foothills. Sundowner winds of similar strength will form over southwest Santa Barbara County by tonight. This will result in a seasonably elevated risk for grass fires in the windy locations. Over the coastal areas, the marine layer will moderate conditions. A significant heat wave will impact the area next week Tuesday through at least Friday. While there remains a range of outcomes in terms of the magnitude of this heat wave, the peak continues to be centered on Wednesday Thursday (July 9-10), at which time high temperatures between 98 and 108 are looking like the most likely outcome for most lower mountains, valleys (including coastal valleys), and deserts. Deep mixing heights will increase the risk for plume dominated fires. Minimum humidities will likely be under 15 percent for most areas away from the coast. There is also a small chance monsoonal thunderstorms over the mountains and deserts, especially towards the end of next week. Southwest to northwest winds of 15 to 25 mph with gusts to 35 mph will likely continue over the typically wind prone areas. All of this likely adds up to an elevated to locally brief critical fire weather scenario. While the chance of reaching classic Red Flag Warning criteria remains low, considering recent fire behavior and the high risk for plume dominated fires, if the hotter outcomes play out a Red Flag Warning might be considered. Heat Advisories look certain, with chance for Heat Warnings. $$ ECC028-051045- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 935 AM PDT Fri Jul 4 2025 ...EXTENDED HEAT WAVE WITH WIDESPREAD ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS WITH THREAT OF LARGE PLUME DOMINATED FIRES NEXT TUESDAY THROUGH FRIDAY (JULY 8-11) ALONG WITH SMALL RISK OF MONSOONAL THUNDERSTORMS...
