Dust Plume Evident in MODIS 1km Color Composite

A fast-moving upper level trough and associated cold front blasted across New Mexico and into Texas on January 22, 2012.  High wind warnings were posted by WFO Albuquerque, Amarillo, Lubbock and Midland. Strong winds were expected to develop across the east plains of New Mexico between 06Z and 12Z and across west Texas soon after. By mid morning, Lubbock also issued a dust storm warning. The Cannon Air Force Base and Clovis observations (in eastern New Mexico) reported blowing dust and visibility restrictions by 16Z. The MODIS 1km imagery below for 1819Z on January 22nd depicts the well-developed dust plume.  Lubbock (KLBB) was reporting one-half mile visibility with blowing dust and a peak wind of 50 knots.

The second and more complete image shows the plume still active 2 hours later at 20Z. The eastern New Mexico observations are not reporting blowing dust, though some areas of dust are evident in the image.  The dust plume is extensive in Texas and has moved into southern Oklahoma. At this time, Lubbock is still reporting one-half mile visibility in blowing dust with a peak with of 46 knots and several other Texas observations are reporting visibility restrictions with blowing dust or “haze.”
