In this video notice how the North Pacific High is being distorted into a dumb ball shape by the storm dropping towards California from the Gulf of Alaska . Today that storm is pressing the North Pacific High’s surface NW winds towards the California coast. But tomorrow the storm will push the North Pacific High to the SW causing the NW wind to fade in Southern California and to give way to southerly storm winds in the Bay Area.
