A quick return to high pressure for Thursday will result in inverted conditions and light winds Thursday morning. Some residual fine particle pollution will also be present. Together, these will allow a rebound in fine particle concentrations Thursday morning, only modestly mixing out during the afternoon, resulting in Moderate AQI from fine particles as a result. Windier southerly flow on Friday should provide some reprieve and more areas of Good air quality. Then copious rain on Saturday should scour the atmosphere, resulting in a return to Good air quality for all areas. For the latest air quality information, please visit our website here. -MDE
