The hot LST and air temperature values combined with dry fuels due to ongoing drought conditions created a very favorable environment for wildfire activity \u00e2\u20ac\u201d and several fire smoke plumes were noted on GOES-13 0.63 \u00c2\u00b5m visible channel images (below; click image to play animation)<\/strong><\/em>. With the largest of the fires located east of Norman, Oklahoma (station identifier KOUN),<\/em> a number of brighter white pyrocumulus clouds could be seen popping up through the lighter gray smoke plume.<\/p>\n
