Forecast Discussion: Today, moderate and occasionally gusty southeasterly winds ahead of an approaching low-pressure system will keep pollutants well dispersed in Rochester. Therefore, AQI levels will be Good. Tomorrow, as the low-pressure system moves through Rochester, moderate southeasterly winds will shift to westerly, effectively dispersing pollutants and resulting in Good AQI levels. Friday, moderate west-northwesterly winds behind the departing low-pressure system will disperse pollutants and transport clean air into Rochester, keeping AQI levels Good. Saturday through Monday, as surface high pressure builds over the northern Great Lakes and a low-pressure system gradually moves across the Plains, moderate to strong easterly winds will develop in Rochester. These winds will keep pollutants well dispersed, leading to Good AQI levels on all three days.
