Widespread grass fires began to burn across parts of southwestern Kansas, northwestern Oklahoma and the Texas Panhandle on 06 March 2017. 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 in Oklahoma) behind a dryline (surface analyses); a cold front then moved southward across the region during the late afternoon and evening hours, bringing strong northerly/northwesterly winds. In a comparison shown above of Shortwave Infrared (3.9 µm) images — 1-minute interval (Mesoscale Sector) 2-km resolution GOES-16 vs. 5-7 minute interval (Rapid Scan Operations) 4-km resolution GOES-13 (also available as a 204 Mbyte animated GIF) — a large fire (the Starbuck Fire) can be seen making a fast northeastward run from Oklahoma into Kansas behind the dryline; then, after the passage of the cold front, the leading edge of that and another large fire turned southward and moved from Kansas back into Oklahoma. Another large fire in the Texas Panhandle (the Perryton Fire) moved rapidly eastward and crossed the border into Oklahoma. At least 7 deaths have resulted from these fires (CNN).
===== 07 March Update =====
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 VIRS (1857 UTC) and Aqua MODIS (1912 UTC) images viewed using RealEarth (below).The creation of true-color and false-color images such as these will be possible using the ABI spectral bands available on GOES-16 and the GOES-R series of satellites. A separate blog post highlighting other multi-spectral GOES-16 views of these fire burn scars on 07 March is available here.
