MODIS False Color Imagery of Southern Plains Blizzard

The 3-day sequence of the SPoRT MODIS false color imagery (28–30 March 2009) nicely depicts the snow cover and subsequent melting over the Southern Plains following the blizzard of 27–28 March. On the 28th (first image), widespread snow is found across the Plains of Colorado, the Texas and Oklahoma Panhandles, and much of southern Kansas, denoted by the red shading in the MODIS false color image. By early afternoon on Sunday the 29th (second image), nearly all the snowpack melted in the Texas Panhandle as temperatures soared into the mid 70s with the onset of lee troughing and downslope warming. Finally, by 1705 UTC 30 March (3rd image), only a narrow band of snow pack remains across far northwestern Oklahoma, and southwestern/south-central Kansas, corresponding to the deepest accumulation of snowfall from the storm (final two images; available on the NWS Dodge City, KS and Wichita, KS web sites).
