Smoke seen in Plains States

There were Code Yellow (Moderate) levels of PM 2.5 seen in the the Pacific Southwest, the Rocky Mountain States, and the southern Plains States (AirNow, top left). There were also Code Orange (Unsafe for Sensitive Groups) and Code Red (Unsafe) levels seen in Texas and Louisiana, along with some Code Orange in Oklahoma. These elevated levels of PM 2.5 were most likely due to smoke from ongoing fires in Florida and South Carolina. There is a good amount of smoke seen in the Plains States and the Mississippi Valley, as seen in NOAA's HMS map, top right. However, this smoke does not seem to have affected the mid Plains States or the northern Mississippi Valley very much. This smoke was seen in NASA's MODIS Terra images, bottom left. The smoke was very thin, and much of it was not seen due to cloud coverage.
