<\/a>GOES-16 Day Snow-Fog RGB images, from 1501-2301 UTC on 13 January [click to play animated GIF | MP4<\/strong><\/a>]<\/p><\/div>GOES-16 (GOES-East)<\/em> Day Snow-Fog RGB<\/strong><\/a> images (above)<\/strong><\/em> showed several well-defined “river effect” cloud plumes — resulting from cold arctic air flowing across unfrozen portions of the Lake Oahe<\/strong><\/a> reservoir along the Missouri River — in addition to widespread horizontal convective rolls (indicative of significant blowing snow and ground blizzard conditions) across parts of central and eastern South Dakota on 13 January 2024<\/strong><\/a>. At Pierre (KPIR) peak wind gusts during the time period shown reached 46 knots (53 mph), and the surface visibility was restricted to 1\/4 mile at times — and even ~50 miles downwind of Lake Oahe at Chamberlain (K9V9) the visibility was as low as 3\/4 mile at times within the cloud plume. Traffic along Interstate 90 near and east of Chamberlain was likely affected by precipitation falling from (and\/or blowing snow in the vicinity of) the Lake Oahe cloud plumes.<\/p>\n A 30-meter resolution Landsat-9 “Natural Color” RGB (or Day Land Cloud RGB<\/strong><\/a>) image at 1730 UTC viewed using RealEarth<\/strong><\/a> (below)<\/em><\/strong> provided a more detailed look at a few of the cloud plumes developing over Lake Oahe and flowing southeastward. Open water appeared as dark shades of blue, while snow cover and ice appeared as shades of cyan.<\/p>\n
