Even though very cold arctic air had invaded much of the north-central US\u00c2\u00a0 (minimum temperatures on the morning of 15 December were -33\u00c2\u00ba F at Havre, Montana and -28\u00c2\u00ba F at Bottineau, North Dakota),<\/em> the deeper man-made lakes (created by dams) along the Missouri River remained unfrozen on 16 December 2008<\/strong>.

GOES-12 10.7 \u00c2\u00b5m IR images (below)<\/em><\/strong> showed the evolution of these “lake-effect cloud plumes” during the night-time and early morning hours on 16 December. While winds at the surface were fairly light, the winds higher aloft (at the 925 hPa or 3000 ft level<\/strong><\/a>) were advecting the cloud material eastward.<\/p>\n
