Breezy to gusty northwest winds of 30 to 55 mph are forecast through Friday across gaps, passes, and some valleys. These winds and poor to moderate RH recovery will lead to dry conditions over the higher elevations, and in particular lead to elevated to near critical fire weather conditions for the East Bay and Santa Cruz mountains. Conditions begin to improve over the weekend, as the marine layer re-establishes and winds ease. 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 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. Sundowner winds of similar strength will form over Santa Barbara County by Friday Night. 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 and valleys (including coastal valleys). 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. $$ ECC028-041630- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 328 PM PDT Thu Jul 3 2025 ...EXTENDED HEAT WAVE WITH WIDESPREAD ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS NEXT TUESDAY THROUGH FRIDAY (JULY 8-11) ALONG WITH SMALL RISK OF MONSOONAL THUNDERSTORMS...
