<\/a>GOES-13 Visible (0.63 \u00b5m)<\/em> images [click to play animation]<\/p><\/div>A southward to southeastward surge of arctic air across the Great Lakes in the wake of a strong cold frontal passage (18 UTC surface analysis<\/strong><\/a>) on 27 February 2014<\/strong><\/a> produced widespread lake-effect snow bands and also contributed to a renewed growth of ice. GOES-13 Visible (0.63 \u00b5m) images (above)<\/strong><\/em> showed (1)<\/strong> a variety of lake-effect cloud bands streaming across Lake Superior, Lake Michigan, Lake Huron, and western Lake Erie, (2)<\/strong> the motion of lake ice, due to strong northerly, northwesterly, and westerly winds across the region, and (3)<\/strong> the rapid formation of new lake ice in the previously ice-free nearshore waters in the far northwestern portion of Lake Superior.<\/p>\n A comparison of Suomi NPP VIIRS Visible (0.64 \u00b5m) and False Color “snow\/ice vs cloud discrimination” Red\/Green\/Blue (RGB) images at 19:02 UTC (below)<\/strong><\/em> demonstrated how the RGB product could be used to highlight the various cloud features — snow and ice appeared as darker shades of red, while supercooled water droplet clouds were depicted as varying shades of white (glaciated cloud features exhibited a pink to lighter red appearance).<\/p>\n
