A winter storm moved over the Texas Panhandle and western Oklahoma on February 25-26, dumping one and a half feet of snow in some areas. Amarillo received the highest amounts, with official totals from the National Weather Service at 19 inches. On February 26, 2013 the Suomi NPP satellite flew over the area, capturing this high resolution visible image of the snow cover. Of course, the lack of color contrast between cloud and snow make differentiating the two difficult. However, if the thermal imagery from the Suomi NPP's VIIRS sensor is used in place of some of the visible imagery, the distinction becomes clearer. In this second image, red areas are snow whereas the lighter pink and white areas are cloud. |
