A large outbreak of blowing dust developed in the wake of a cold frontal passage across parts of New Mexico, Texas, and Oklahoma on 22 January 2012<\/strong>. At Lubbock, Texas winds gusted to 60 mph, and surface visibility was reduced to 0.5 mile. The strongest wind gust was 77 mph, farther to the north in the Texas panhandle region (NWS Lubbock summary<\/a><\/strong>). Early in the day, the consolidation of numerous smaller blowing dust plumes into a single large blowing dust “cloud” could be seen on 1-km resolution GOES-15 (GOES-West) 0.63 \u00c2\u00b5m visible channel images (above; click image to play animation)<\/em><\/strong>.<\/p>\n

Later in the day, due to a more favorable forward scattering angle, the areal extent of the airborne blowing dust could be better seen on 1-km resolution 0.63 \u00c2\u00b5m visible channel images from the GOES-13 (GOES-East) satellite (below; click image to play animation)<\/em><\/strong>. The leading edge of the primary large dust plume began to move northeastward over Oklahoma, while a number of smaller dust plumes could be seen moving southeastward across the Oklahoma and Texas panhandle regions behind a secondary cold front. Note that the GOES-13 satellite had been placed into Rapid Scan Operations (RSO) mode, providing images as frequently as every 5-10 minutes.<\/p>\n

There was also a bit of smoke mixed in with the blowing dust, due to a few small wildfires that were burning across the region. Three small wildfire “hot spots” (dark black to yellow pixels)<\/em> could be seen on an AWIPS image of 1-km resolution MODIS 3.7 \u00c2\u00b5m shortwave IR data at 20:00 UTC (below)<\/em><\/strong>.<\/p>\n
