Forecast Discussion: Saturday, November 22: Surface high pressure over the southeastern U.S. will generate moderate southerly winds in the Mahoning Valley. These winds will transport regional pollutants and moisture into the area, increasing particle production and leading to low-Moderate AQI levels. Sunday, November 23: As a fast-moving low-pressure system approaches from the west, winds will shift to southeasterly, bringing additional pollutants into Youngstown-Warren. Furthermore, moisture associated with rain showers will aid particle formation. As a result, AQI levels remain Moderate. Monday, a cold front will move through northeastern Ohio in the afternoon, enhancing atmospheric mixing and shifting winds to southwesterly. These weather conditions will disperse pollutants, lowering AQI levels to Good. Tuesday, moderate southwesterly winds behind the departing cold front will disperse pollutants and bring clean, cool air into the Youngstown-Warren region, yielding Good AQI levels. Wednesday, wind speeds will decrease, reducing pollutant dispersion. However, low-pollutant carryover from previous days will keep AQI levels Good. Thanksgiving, a weak low-pressure system moving through Ohio will increase mixing in the atmosphere, keeping pollutants well dispersed. As a result, AQI levels will remain Good.
