As was highlighted in news stories posted by the National Weather Service forecast offices at Chicago<\/strong><\/a> and Milwaukee<\/strong><\/a>, a large amount of sediment was seen in southern Lake Michigan following a strong wind event which produced very large waves. A comparison of 250-meter resolution MODIS true color<\/a><\/strong> Red\/Green\/Blue (RGB) images from the SSEC MODIS Today<\/a><\/strong> site (above)<\/em><\/strong> showed one particularly large sediment feature protruding northward from the southeastern part of Lake Michigan on 02 October<\/strong><\/a> and 03 October 2011<\/strong><\/a>.<\/p>\n

A comparison of AWIPS images of 1-km resolution MODIS 0.65 \u00c2\u00b5m visible channel data with the corresponding 1-km resolution MODIS Sea Surface Temperature (SST) product on 03 October (below)<\/em><\/strong> showed that while the prominent sediment feature was embedded within a larger scale area of warmer waters (SST values in the lower 60s F, darker red color enhancement)<\/em> in the far southern part of the lake, there was not necessarily a 1:1 correspondence between the sediment pattern and the sea surface temperature pattern.<\/p>\n

GOES-13 0.63 \u00c2\u00b5m visible channel imagery (below; click image to play animation)<\/em><\/strong> indicated that the prominent sediment feature was moving slowly northward early in the day on 03 October — however, once the northwesterly winds reported by the mid-lake buoy began to increase and gust to 16 knots later in the day, the northward motion of the sediment feature appeared to slow somewhat.<\/p>\n
