On This Day in Iowa Weather History

November 27

1994: Significant snowfall occurred roughly northwest of a line from Onawa to Algona where thunder accompanied the snow at times. Snowfall amounts ranged up to as high as 12.5 inches at Rock Valley and 14.0 inches at Rock Rapids. At the Sioux City airport 8.3 inches of snow was recorded along with wind gusts to near 40 mph making travel hazardous with blowing snow and low visibilities.

1990: A storm system produced a mix of sleet, snow, freezing rain, and heavy rain across Iowa bringing an abrupt end to several days of record warmth. Rainfall accumulations were highest in southeastern Iowa where Fort Madison recorded 3.10 inches. Across the northwestern two thirds of the state freezing precipitation left an icy coating on many bridges and contributed to scores of traffic accidents.

1983: A major winter storm struck Iowa on November 26-28 producing heavy snow accumulations across western, northwestern, and north central portions of the state. Strong winds blew the snow into large drifts and created blizzard conditions which immobilized the region. The highest storm total snowfall amounts included 12.0 inches at Sibley, 12.5 inches at Castana, 13.0 inches at Hawarden, 13.3 inches at Storm lake, 13.6 inches at Sioux City, and 17.2 inches at Le Mars. A warehouse in Sioux City collapsed due to the high winds and weight of snow on the roof.

1960: Severe thunderstorms produced damaging winds across portions of Iowa and a small tornado near Clarinda. Only three tornadoes have ever been recorded in Iowa on a later date of the year.
