On This Date (3/11) In Weather History

This date in 1977 started a cool and wet period across all but far western South Dakota.  Highs were mainly in the 40s, and a chilling rain fell which continued into the 12th. Some of the rain was quite heavy, bringing average amounts from an inch and a half to 3 inches rainfall.  Less than a week prior, a blanket of 6 to 18 inches snowcover resided across the area, and this snow was virtually gone by the start of this rainy period.  The result of the preceding snowmelt and heavy rainfall was minor to moderate flooding along the middle portions of the James and Big Sioux Rivers in the following few days.
