The Bay Area and north Central Coast remains under the western side of a strong upper level high pressure ridge located over the western states. Large scale sinking air, compressional warming and drying aloft, a strong low level temperature inversion coupled to diurnal late August solar warming is resulting in hot and dry conditions over the interior today. It`s cooler along the immediate coast due to a shallow marine layer and generally light to locally moderate afternoon sea breezes. Above the shallow marine layer very low daytime humidities and poor overnight recoveries are expected to continue just away from the immediate coast. Winds remain onshore, but breezy afternoon winds will elevate the fire weather threat in the interior mountains, especially through favored gaps and passes. ...Discussion from SFOFWFEKA...
