Here’s a MODIS satellite picture of Lake Michigan from Saturday.  Note the cumulus clouds that form over land (Door Co. Wisconsin, Mission Peninsula  and around Traverse Bay (but not over the water).  You can see some of the fields have turned yellow, esp. west of Chicago.  You can also see my famous tornado scar WNW of Green Bay from the tornado that occurred in June 2007.  Here’s MODIS pictures of Lake Huron, Lake Erie (you can see the Cedar Point Amusement Park), Lake Ontario and Lake Superior.  Now check out this picture taken Sept. 4 of fresh snow on the mountains of central Siberia/Russia.  And check out this picture of dust plumes blowing to the north (toward the top of the picture) in Argentina.  The MODIS site says:  “Laguna Mar Chiquita is a shallow lake that expands and shrinks, depending on available water. At its peak, the lake covers roughly 5,770 square kilometers (2,230 square miles), but it can shrink to about 1,960 square kilometers (760 square miles) during periods of extended drought. When the water level drops, winds can pick up the fine sediments around the lake perimeter and create dust storms. The dust plumes in this storm extended for hundreds of kilometers (visible in the image).”  NASA image courtesy Jeff Schmaltz, LANCE MODIS Rapid Response Team at NASA GSFC.   Caption by Michon Scott.
