A comparison of AWIPS 0.64 \u00c2\u00b5m visible channel and false-color Red\/Green\/Blue (RGB) images at 18:49 UTC (below)<\/strong><\/em> confirmed that most of Lake Michigan was cloud-free — snow and ice appear as varying shades of red on the RGB image, which supercooled water droplet clouds appear as shades of white.<\/p>\n

As winds changed to southerly and southwesterly in the wake of a retreating surface high pressure on 06 March<\/strong><\/a>, a corresponding change in Great Lakes ice motion was seen on GOES-13 0.63 \u00c2\u00b5m visible channel images (below; click image to play animation)<\/strong><\/em>.<\/p>\n
