High pressure aloft will linger while slowly weakening over southwest California into this evening then start to build back in from the east on Saturday. A gradual cooling trend will continue this afternoon with highs near or slightly below normal for many areas, then warm several degrees over the weekend into early next week. Minimum humidities will generally range between 10 and 25 percent across interior sections each afternoon through Saturday, except locally in the upper single digits in some mountain and desert areas. Minimum humidities in these areas will turn slightly higher Sunday and Monday into the 15-25 percent range overall. Gusty southwest winds of 25 to 40 mph will prevail across the Antelope Valley each afternoon and evening through Monday, except for isolated gusts up to 45 mph at times in the nearby foothills. The combination of low humidity with gusty onshore winds will continue to produce elevated fire weather conditions across the Antelope Valley each afternoon and evening through Monday. The upper level flow will turn southeast to south over the weekend and continue into early next week, helping to import mid- level monsoon moisture and increased instability into the forecast area. In addition, an upper level disturbance is forecast to move mainly into San Luis Obispo and Santa Barbara Counties from the south by Sunday and linger Sunday night into early Monday. A slight chance afternoon thunderstorms is forecast for the Los Angeles County Mountains and Antelope Valley Sunday and Monday, with the focus in the mountains over the San Gabriels. However, the upper level disturbance will bring a slight chance of showers or thunderstorms to San Luis Obispo and Santa Barbara Counties Sunday through early Monday. Any thunderstorms that develop between Sunday and Monday would be capable of producing isolated dry lightning outside of rain shafts, as well as gusty downdraft winds. ...Discussion from Monterey... ...FIRE WEATHER WATCH FOR DRY LIGHTNING SUNDAY INTO MONDAY... A high pressure system centered over the Four Corners region will backbuild towards California over the weekend and into early next week. This will result in a gradual warming and drying trend that will peak on Tuesday especially for the interior. The marine layer will become compressed down to 1000 to 1500 feet but continue to hug the coast and promote fair overnight humidity recoveries though dry air will be present atop the marine deck. Elevated monsoonal moisture and instability rotating around this system will result in a risk of elevated thunderstorms between Sunday and Monday from south to north. A combination of dry and wet thunderstorms are possible, however, dry fuels and lightning strikes displaced from rain shafts could lead to new ignitions even with the wet thunderstorms. $$ ECC028-171700- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 354 PM PDT Fri Jul 16 2021 ...ELEVATED FIRE WEATHER CONDITIONS THROUGH MONDAY FOR THE ANTELOPE VALLEY AND NEARBY FOOTHILLS DUE TO LOW HUMIDITIES AND GUSTY WINDS... ...ISOLATED DRY LIGHTNING POSSIBLE SUNDAY THROUGH MONDAY FOR SLO AND SANTA BARBARA COUNTIES...THE LOS ANGELES COUNTY MOUNTAINS AND ANTELOPE VALLEY...
