Widespread large grass fires began to burn across parts of northwestern Oklahoma, southwestern Kansas, and the Texas Panhandle on 06 March 2017<\/strong><\/a>. The fires grew very quickly during the late morning and early afternoon hours, due to strong southwesterly winds (with gusts as high as 67 mph<\/strong> in Oklahoma)<\/em> behind a dryline (surface analyses<\/strong><\/a>); a cold front then moved southward across the region during the late afternoon and evening hours, bringing strong northerly\/northwesterly winds.<\/p>\n

Another large fire in the Texas Panhandle (the Perryton Fire<\/strong><\/a>) moved rapidly eastward and crossed the border into Oklahoma (moving a distance of about 45 miles), before also turning abruptly southward in the wake of the aforementioned cold frontal passage. A total of 7 deaths resulted from these fires (CNN<\/strong><\/a>).<\/p>\n

===== 07 March Update =====<\/strong><\/p>\n

On the following day, the large size of the grass fire burn scars could be seen in comparisons of true-color and false-color Red\/Green\/Blue (RGB) images from Terra MODIS (1732 UTC), Suomi NPP VIIRS (1857 UTC) and Aqua MODIS (1912 UTC) images viewed using RealEarth<\/strong><\/a> (below)<\/strong><\/em>. The burn scars appeared as dark areas in the true-color images, and shades of tan to darker brown in the false-color images.<\/p>\n
