Forecast Discussion: Today, as a low-pressure system passes to the south of Rochester and departs to the east, moderate northwesterly winds will keep pollutants well dispersed, yielding Good AQI levels. Tomorrow, light to moderate southwesterly winds will gradually transport pollutants and moisture into Rochester during the morning hours, enhancing particle production. However, winds will shift to northerly in the afternoon, dispersing pollutants and bringing cleaner air into the region. As a result, AQI levels will be Good. Monday and Tuesday, moderate northwesterly winds will disperse pollutants and transport clean, dry air into Rochester. These conditions will keep AQI level Good on both days. Wednesday and Thursday, a low-pressure system over the Hudson Bay will generate moderate westerly winds in Rochester, keeping the lower levels of the atmosphere well mixed and leading to Good AQI levels on both days.
