cold front. Deep mixing and strong transport winds will create
excellent smoke dispersal, with low relative humidities this
afternoon. Rain showers are expected tonight, with the best
chances shortly after midnight. However, rainfall amounts will be
a tenth of an inch or less. Dry weather and slightly cooler
temperatures return on Wednesday with winds from the NW.
