Forecast Discussion: Threshold Moderate conditions are expected Saturday as winds swing to the southwest. Inverted conditions on Sunday lead to Moderate fine particle concentrations in the urban corridor but upper Good AQI elsewhere. Despite a cold front moving through on Monday, fine particle AQI will remain at the Good/Moderate threshold for the daily average. Recirculation begins on Tuesday, with threshold Good/Moderate conditions eventually giving way to Moderate conditions Wednesday. - MDE
