Expect tonight to be the last night widespread cool temperatures and good humidity recoveries before a much hotter and drier pattern settles into the region for the first half of the work week. Well above average high temperatures with a mostly eroded marine layer are expected and will make for widespread warm and dry conditions. High temperatures and light offshore winds in the far interior areas will bring the minimum RH into the low teens. Overnight cooling will be limited in the interior areas as well as RH recoveries. Winds will remain light to moderate, and may flip to onshore in the afternoons. As such, we are not expecting to hit Red Flag criteria. Onshore wind will return in the second half of the week, gradually decreasing fire weather concerns. Note : All winds are 20-foot Winds Unless otherwise specified. Thunderstorms imply strong, gusty and erratic winds. ...Discussion from Los Angeles/Oxnard... ...ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS MAINLY OVER THE MOUNTAINS TODAY EXPANDING TO VALLEYS AND COASTAL FOOTHILLS MONDAY THROUGH WEDNESDAY WITH THREAT OF LARGE VERTICAL PLUME GROWTH... Warm and dry conditions are expected to continue away from the coast through Wednesday. High temperatures between 90 and 100 will be common through Monday, then increasing to 93 to 106 on Tuesday and Wednesday. The warmer temperatures are expected to spread into many of the valleys and coastal foothills Monday through Wednesday as a weak offshore wind influence develops. Humidity levels will fall to between 5 and 20 percent over the interior valleys, mountains, and deserts today, with the drier air expanding into the coastal valleys and foothills Monday through Wednesday. South to east wind gusts of 20 to 30 mph will be common across the interior today, strongest in the mountains. By Monday and Tuesday, the winds will become more northeast to southeast over the interior, likely expanding into other areas such as the Santa Lucias, Santa Susana mountains, and portions of the LA/Ventura county valleys. On Monday, southeast winds gusting 20 to 30 mph will be common across the San Gabriels and Ventura county mountains, with isolated gusts as high as 35 mph across ridgetops. Mixing heights are expected to peak between 8,000 and 13,000 feet this afternoon across the interior, then increase to between 10,000 and 17,000 feet Monday through Wednesday due to increasing temperatures and instability. As a result, there will be an increased risk of large vertical plume growth of new fires across the interior Monday through Wednesday. mainly in the mountains and foothills. The combination of hot temperatures, very low humidities, locally gusty winds and potential for large vertical plume growth will result in elevated to brief critical fire weather conditions today in the mountains, expanding into the Santa Lucias, Santa Susana mountains, and portions of the valleys Monday into Wednesday. A slight cooling trend could develop Thursday into Friday, then a possible offshore wind influence may reinforce very warm and dry conditions next weekend. $$ ECC028-301630- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 327 PM PDT Sun Sep 29 2024 ...ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS MAINLY OVER THE MOUNTAINS TODAY EXPANDING TO VALLEYS AND COASTAL FOOTHILLS MONDAY THROUGH WEDNESDAY WITH THREAT OF LARGE VERTICAL PLUME GROWTH...
