Forecast Discussion: Good air quality is expected to continue for the next several days. A weak low pressure system is forecast to develop off our coast overnight Monday into Tuesday. Some light to moderate precipitation along with great vertical mixing will keep fine particle concentrations low. As the low pressure system pushes off to our north and east on Wednesday, brisk northwest winds will keep AQI values Low. -MDE
