Forecast Discussion: Memorial Day, a low-pressure system will gradually move through Minnesota, enhancing atmospheric mixing and generating moderate southwesterly winds. These weather conditions will effectively disperse pollutants in the Rochester area, resulting in Good AQI levels. Tomorrow, light to moderate northerly winds behind the departing low-pressure system will disperse pollutants in the Rochester area, yielding Good AQI levels. Wednesday, lighter winds will reduce pollutant dispersion in the Rochester area. However, low pollutant carryover from previous days will keep AQI levels Good. Thursday, as a low-pressure system approaches from the west, light to moderate southeasterly winds ahead of it will bring additional pollutants into the Rochester area. As a result, AQI levels will be low-Moderate. Friday, as the low-pressure system moves east and surface high pressure builds over the northern Plains, moderate northerly winds will effectively disperse pollutants in the Rochester area, yielding Good AQI levels. Saturday, surface high pressure over the northern Great Lakes will produce moderate northeasterly winds in the Rochester area, dispersing pollutants and keeping AQI levels Good.
