Canadian high pressure will move overhead for the weekend, helping to keep temperatures cool and dew points low. This along with a clean residual air mass will ensure Good air quality across the state. High pressure shifts off the East Coast, persisting for several days. Temperatures and dew points will be on the rise as winds shift southerly. This southerly flow will also help to tap into diffuse smoke linked to agricultural burning common across the Southeast states this time of year. As a result, expect an uptick in fine particulates to the low Moderate range for Monday and Tuesday. A frontal system will work its way south through the state Wednesday afternoon. Clean air will begin to filter in behind the front. However, given the timing of frontal progression, expect threshold Good to low Moderate PM2.5 levels across the state for a 24-hour average.
