The southerly flow of warm, moist air over the still-cold waters of Lake Superior on 21 July 2014<\/strong><\/a> led to the formation of some interesting lake fog patterns, as seen in McIDAS images of GOES-13 0.63 \u00b5m visible channel data (above; click image to play animation; also available as an MP4 movie file<\/a>)<\/strong><\/em>. The images above are shown in their native GOES-13 satellite projection.<\/p>\n

A similar animation of AWIPS images of re-mapped GOES-13 visible channel data with overlays of METAR surface reports and buoy reports (below; click image to play animation)<\/strong><\/em> showed that three of the northern Lake Superior buoys were reporting a water temperature of 38 to 39\u00ba F. As far north as Thunder Bay, Ontario (CYQT), air temperatures exceeded 90\u00ba F and the dew point exceeded 70\u00ba F.<\/p>\n
