A strong jet dug into the southwestern U.S. on November 25 and ejected into the plains by early November 26, where a surface low pressure area began to organize in the southern High Plains.  The mid-level trough and surface cyclone intensified rapidly lifting toward the western Great Lakes by the morning of November 27. With sharp baroclinicity in place, a band of moderate to heavy snowfall from 4 to 9 inches blanketed far southeast South Dakota, northeast Nebraska, northwest Iowa, and much of southwest Minnesota. The snow was accompanied by northwest winds with gusts as high as 35 to 50 mph near and east of Interstate 29, which resulted in periodic visibility from one-quarter to one-half mile. Some heavier snowfall amounts across southeast South Dakota included 6.5 inches 6 miles southeast of Centerville, 6 inches at Yankton, 5.6 inches 2 miles north of Chester, 5.5 inches 6 miles northwest of Montrose and Menno, 5.3 inches 4 miles northwest of Renner, and 5.0 inches at Hurley.
