Weekend Edition: Generally good air quality across the nation; Fires in south
The air quality continues to be generally good across the country except for some fire activity which is clearly visible in the otherwise clear skies. The NOAA HMS product identifies the fire counts from Saturday and shows a broad area of light smoke from Kansas down through Mississippi. Two fires in that mix are shown below (the left one from northeastern Georgia and the right one showing two fires from the panhandle of Florida).

We didn't have much evidence of the dust plume on Friday and Saturday reaching the mid-Atlantic but now we have the CALIPSO cross-section through the region and it does show elevated aerosol over the mid-Atlantic (at about 35-40N, -77-79W).

A very quiet air quality day in the US today. To quote our friends over at NOAA's Hazard Mapping Service "There are no significant areas of remnant smoke observed in visible satellite imagery this morning." There was a pretty cloud street pattern observed over western Nevada today in MODIS imagery.
