Weather Update: Hot and Stormy Days Ahead in DC Area.

Air quality in the D.C. region is straddling the yellow and orange levels on the U.S. Air Quality Index on Sunday afternoon, which means that air quality is generally acceptable but that people who are sensitive to air pollution could be at risk. A cold front Monday should bring continued air quality improvement, more humidity and beneficial rain in the form of thunderstorms. With a half-inch to an inch of rain possible Monday, we may halt the increasingly dry (and drought) conditions in our region.
