Good AQI; High NO2 in Northeast region
Good air quality was registered today throughout the nation. Only moderate levels were detected in the Mid - Atlantic and Northwest regions as well as in California (top left). Ozone levels were also good over the whole country. It seems that fires are over for now. Although some scattered fires could be detected no significant smoke from them seen from them (top right). However, an area of moderately dense blowing dust extends across parts of central Nebraska, Kansas and far northeastern Colorado. The dust is heading toward the southeast. Unfortunately there is no image for this particular dust. Finally, High NO2 concentrations were retrieved by OMI in the Northeast region. The NO2 levels were high yesterday but today the show bog e even higher (bottom).

You may be interested to see a link that has some video and other info on this event: http://www.accuweather.com/en/weather-news/photos-winds-damage/419184 Winds were quite stout with lots of reports of sustained winds of 40 kt and gusts over 50 kt in the area.
By the way, not surprisingly, there were also some fires that were caused by the strong winds in the area. So there was also some smoke mixed in with all the dust. Looking at today's GOES visible imagery, the NWS dust forecast (http://airquality.weather.gov/) still looks to be in fairly good shape as there is a broad area over the Tennessee Valley back into northeast Texas.
The forecast indicates the dust should be moving over the DC metro area and UMBC this evening and overnight.
