Blowing dust pushing Southeast; Code Red AQI across Texas Panhandle

Several area of powerful winds and blowing dust/sand were visible today across Texas, stretching from Muleshoe through Lamesa, Texas and across the Mississippi River Valley associated with the powerful low pressure system that spurred the severe weather in the Southeast (top left). The blowing dust likely contributed to Code Red AQI observed in Lubbock, TX and Code Yellow across the Southern Plains (top right). According to the HMS analysis team, a large area of smoke was also visible across eastern Texas, and may also be contributing to elevated conditions (bottom left). A huge swath of smoke was also reported in the Gulf of Mexico, and is likely related to the elevated aerosol optical depth (AOD) observed by this afternoon's MODIS Terra overpass (bottom right).
