Upper level high pressure over the Four Corners area will bring monsoonal moisture into the area the first half of this week. This monsoonal moisture will bring the threat of afternoon thunderstorms to the mountains and deserts. For this afternoon, the thunderstorm threat will be confined to the mountains of Ventura and Los Angeles counties as well as the Antelope Valley. On Tuesday, the moisture will increase with the threat of afternoon thunderstorms spreading into the eastern half of the Santa Barbara county mountains. On Wednesday and Thursday, the thunderstorm threat will gradually diminish over the mountains of Ventura and Los Angeles county mountains and the Antelope Valley. Any thunderstorms that develop will be capable of producing heavy rain and flash flooding, especially on Tuesday. Despite the potential for heavy rain, there may be lightning strikes on the periphery of any storms which could trigger fire ignitions. Gusty and erratic downdraft winds could result in the quick spread of any fire ignitions. Otherwise, hot conditions will persist across interior sections today through Friday with widespread temperatures in the 90s to low 100s across the warmest valley, mountain and desert locations. Relative humidity will remain between 15 and 30 percent each afternoon with poor to moderate overnight recovery. With the typical onshore winds each afternoon, elevated fire weather conditions will persist across interior sections through Friday. The hot and dry conditions will bring the potential for plume-dominated fires with projected mixing heights between 10,000 and 17,000 feet. ...Discussion from Monterey... A gradual cooling trend is forecast through much of the week, although inland areas and the hills will remain warm and dry through midweek. Monsoon moisture will move across the district from south to north late Tuesday night and Wednesday. Thunderstorm potential associated with this moisture is remote, with thunderstorm chances considered too low to add to the forecast. Winds will be generally light through the week except locally moderate and gusty west to northwest winds at times, mainly near the coast. Note : All winds are 20-foot Winds Unless otherwise specified. Thunderstorms imply strong, gusty and erratic winds. $$ ECC028-031645- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 333 PM PDT Mon Sep 2 2019 ...SLIGHT CHANCE OF AFTERNOON THUNDERSTORMS OVER THE MOUNTAIN AND DESERTS TODAY THROUGH THURSDAY WITH THREAT OF FLASH FLOODING... ...ELEVATED FIRE WEATHER CONDITIONS ACROSS INTERIOR SECTIONS THROUGH FRIDAY DUE TO EXTENDED PERIOD OF HOT TEMPERATURES AND GUSTY ONSHORE WINDS...
