Thursday, May 28: Moderate northerly winds will transport cleaner, cooler air into the Mahoning Valley behind a departing cold front. Thus, AQI levels will improve to Good. Friday, May 29: Calm to light westerly winds through much of the day will lead to pollutant build-up in Youngstown-Warren. In addition, mostly sunny skies will enhance ozone formation. However, low pollutant carryover from Thursday will lead to high-Good AQI levels. Saturday, moderate to gusty north-northeasterly winds will disperse pollutants as surface high pressure strengthens to the north. In addition, cooler temperatures will keep ozone development in check. Therefore, AQI levels will be Good. Sunday, as surface high pressure stretches across the Mahoning Valley, light and variable winds will limit mixing and dispersion. Furthermore, mostly sunny skies will enhance ozone development, leading to low-Moderate AQI levels. Monday and Tuesday, as the next high-pressure system builds over the Great Lakes, northerly winds will strengthen over northeastern Ohio, dispersing pollutants. Furthermore, pollutant carryover from day to day will be low. Therefore, despite mostly sunny skies supporting ozone production, AQI levels will be high-Good on both days.
