Forecast Discussion: A fairly unsettled weather pattern is expected to persist over the next several days. Waves of high and low pressure systems will move through our area, giving us periods of heavy precipitation as well as gusty winds. Both of these conditions are favorable for low fine particle concentrations. Expect Good AQI values to persist for the foreseeable future. -MDE
