Storm total snowfall included 8 inches at Sisseton, 5 inches at Watertown and Wheaton, 4 inches at Aberdeen, and 2 inches at Mobridge.

Heavy snow of 7 to 12 inches was reported in north-central South Dakota on the 7th. Timber Lake and Eagle Butte each reported 12 inches of snow.

U.S.A and Global Events for December 7th:

December 7, 1740:

By all accounts, the Merrimack River in New Hampshire flooded on this day. The flood is likely the first recorded in New Hampshire. "The snow melted, and a freshet occurred in the Merrimack River, nothing like it having been experienced there for seventy years. At Haverhill, the stream rose fifteen feet, and many houses were floated off." (Perley, Sidney, 1891, Historic storms of New England p. 49-51).

 

December 7, 2006:

A rare tornado tore through Kensal Rise in London. This T4 on the TORRO scale, equivalent to an F2 on the Fujita scale, injured six people and damaged 150 homes. According to the BBC, the last tornado which caused significant damage in London was in December 1954, in West London.
