Plume from Canada extending down to Baltimore

Looking at the NOAA HMS Smoke and Fire Product (top left), the clumps of small red dots indicate masses of currently burning fires, with smoke plumes being indicated by the grey patches. The largest plumes continue to be a result from wildfires in Canada, while the smaller plume in the Pacific Northwest results from the currently burning fires in that region. The MODIS Terra image (top right) illustrates how the Canadian plume is affecting AOD in the northeast United States as well, even reaching down into Maryland.

The EPA AIRNow combined AQI loop (bottom left), however, shows only moderate AQIs for the East. The highest AQIs result around the Pacific Northwest fires, with the current high AQI occurring in Burns, OR (166). The image to the bottom right is from the MODIS AOD trajectory at 300 UTC on August 9, predicting winds to take the troublesome Canadian plume into the Mid-Atlantic, directly in the path of Maryland. Based on this model, it is very possible that smoke will be affecting air quality in the Baltimore area for the weekend.
