A localized dust storm is kicked up by low-level outflow that races ahead of a cold front in southern New Mexico.
This is an animation loop from visible light weather satellite images, overlayed with composite radar, 500mb isobars and wind barbs, and county boundaries and highways.
The screengrab is annotated to show the direction of motion and the low-level outflow boundary that kicks up lots of desert dust. (This screengrab is taken from one of the later frames in the animation loop.)
You probably have to watch the loop more than once to see the subtle initial appearance of the low-level outflow boundary and dust...that becomes all too obvious by the end of the animation loop.
[Edit/add: METAR history (final screengrab) for Alamogordo showing how visibility went to hell as the outflow and dust storm moved into the area.
