Oct 18-22, 2019 Cool and windy conditions are in store for Friday and throughout the weekend as a small cold front moves through our area. Inland areas can expect lighter breezes and slightly warmer daytime temps than the coastal areas. Not expecting much, if any, in the way of precipitation south of Santa Cruz mountains. High pressure rebuilds next week bringing warmer daytime temperatures and nighttime thermal inversion. Inversions are when warmer air aloft traps colder air below causing any smoke generated from fireplace and wood stove use to be trapped at ground level until the following day begins to warm allowing most smoke to lift. Smoke can linger in canyon and valley communities where wind does not readily flow to flush it out. Windy daytime conditions should mean favorable mixing which will help remove built up overnight smoke. Overall air quality is expected to be GOOD throughout the district for the weekend.
