A strong cold front was moving southward across the High Plains during the day (surface analyses<\/strong><\/a>) — and arrived at the grass fire’s location just after 2000 UTC (causing a brief flare-up of the fire thermal signatures, and a final pyrocumulus pulse). The surge of colder air behind the cold front showed up as darker shades of green in the 3.9 \u00b5m<\/span> images. Th initial east-southeastward expansion of the hot thermal 3.9 \u00b5m<\/span> signature quickly transitioned to a south-southwestward expansion in the wake of the frontal passage.<\/p>\n 1-minute GOES-16 True Color RGB images created using Geo2Grid<\/strong><\/a>\u00a0(below)<\/strong><\/em> showed the initial eastward spread of the smoke plume prior to the arrival of the cold front — followed by a pronounced south-southwestward transport of smoke from the fire source region after the cold front moved across the area.<\/p>\n GOES-16 True Color RGB images [click to play animated GIF | MP4<\/strong><\/a>]<\/p><\/div>The polar-orbiting Suomi-NPP<\/strong><\/a> satellite passed over that region around 1923 UTC<\/strong><\/a> — a toggle between True Color and False Color RGB images is shown below.
