An Excessive Heat Warning is in place for most of our interior locations, with a Heat Advisory for some locations closer to the shoreline that may still see minimal influence of the Marine Boundary Layer. Minimum RH values inland for the upcoming week and beyond will mostly be in the teens, with some single digit values in areas of higher elevation. Overnight RH recover will be poor to non-existent as the heat wave persists through the week, and potentially into next weekend. The hot and dry conditions continue to move ERCs into the 70-80 percent range. With the long holiday weekend, and the many outdoor activities expected, people need to be careful with any campfires, and fireworks should not be used. Any wildfire that ignites will have the potential for rapid spread. Lightning is the only natural ignition for wildfires and there are no thunderstorms in the forecast. 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 INTERIOR VALLEYS, MOUNTAINS, AND DESERTS TODAY THROUGH MONDAY DUE TO HOT AND DRY CONDITIONS WITH LOCALLY GUSTY ONSHORE WINDS... ...LONG DURATION OF ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS INTO NEXT WEEKEND FOR AREAS AWAY FROM THE COAST DUE TO HOT TEMPERATURES, LOW HUMIDITIES, LOCALLY GUSTY WINDS, AND DRYING FUELS... ...POTENTIAL FOR GUSTY AND HOT SUNDOWNER WINDS TO BRING ELEVATED TO CRITICAL FIRE WEATHER CONDITIONS FOR SOUTHERN SANTA BARBARA COUNTY LATE THURSDAY INTO FRIDAY NIGHT... A broad upper level trough over the West Coast will gradually weaken through Monday. This will bring a gradual warming and drying trend to all areas through Monday with the best warming away from the coast. The marine inversion will remain quite shallow with night and morning low clouds and fog confined to the coastal plain. For the interior valleys, mountains, and deserts, humidity values are expected to lower to between 8 and 20 percent today and Monday. The hotter temperatures, low humidities, and locally gusty onshore winds will bring elevated fire weather conditions across the interior valleys, mountains, and deserts today through Monday. Beginning on Tuesday, and continuing into next weekend, high pressure will build into the region from the Eastern Pacific. This will likely bring a significant and long duration heat wave away from the coast from Tuesday through next weekend. High temperatures between 100 and 110 degrees will be common across the interior during this period, with temperatures potentially rising to between 110 and 115 degrees across the Antelope Valley and San Luis Obispo County interior valleys during the peak of the heat Thursday through Saturday. Overnight lows will also remain quite warm, adding to the potential for dangerous heat mid to late week. Widespread humidity values between 7 and 15 percent will likely occur across the interior during this period, along with poor humidity recoveries, especially in the mountains, foothills, and Antelope Valley. Typical gusty onshore winds are expected across interior sections in the afternoon and evening hours, with gusts of 20 to 35 mph common. There is also the potential for gusty sundowner/I5 corridor winds late Thursday into Friday night which could bring hot and dry conditions into portions of southern Santa Barbara county. Given the very hot temperatures, low relative humidity, and locally gusty winds, an extended period of elevated to brief critical fire weather conditions are likely from Tuesday through Sunday for valley, foothill, mountain, and desert locations. Elevated to critical fire weather conditions may expand into southern Santa Barbara county if the sundowner winds develop late Thursday into Friday night. The hot and unstable conditions will also increase the threat of large vertical plume growth for any fires that develop across the interior. The very hot and dry conditions will also cause a significant drop in both live and dead fuel moisture levels this week. These drying fuels combined with the expected fire weather conditions and increased outdoor activities due to 4th of July will cause the large fire threat to become high for areas away from the coast Tuesday through next weekend. $$ ECC028-012045- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 735 PM PDT Sun Jun 30 2024 ...ELEVATED FIRE WEATHER CONDITIONS ACROSS INTERIOR VALLEYS, MOUNTAINS, AND DESERTS TODAY THROUGH MONDAY DUE TO HOT AND DRY CONDITIONS WITH LOCALLY GUSTY ONSHORE WINDS... ...LONG DURATION OF ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS INTO NEXT WEEKEND FOR AREAS AWAY FROM THE COAST DUE TO HOT TEMPERATURES, LOW HUMIDITIES, LOCALLY GUSTY WINDS, AND DRYING FUELS... ...POTENTIAL FOR GUSTY AND HOT SUNDOWNER WINDS TO BRING ELEVATED TO CRITICAL FIRE WEATHER CONDITIONS FOR SOUTHERN SANTA BARBARA COUNTY LATE THURSDAY INTO FRIDAY NIGHT...
