Today’s weather forecast will be favorable for continued clearing of accumulated smoke. Increased ventilation and stronger afternoon winds will support clearing air for most of the forecast area. Our heaviest smoke impacts will be in the midday hours as the inversion breaks and smoke mixes to the surface.
