Southern California Weather Force has issued a Santa Ana Wind Advisory effective Wednesday into Thursday for the nominal prone zones.
Discussion: As a storm today passes to the north, drier air will be in place, especially on Thursday. This will generate offshore gradients for moderate Santa Ana Winds. The mountains and deserts will be first on Wednesday with northwest winds, including the Santa Clarita Valley. These will switch north and the northeast on Thursday for primarily below passes and canyons. In essence, this is a split pattern depending on location and day.
