Greatest 24-hour Snowfall on Record for the U.S.?

This past week some exceptional snowfall amounts were reported in northern Wisconsin (50.1” at Gile) and the Upper Peninsula of Michigan (42.5” at Ishpeming 7 NNW) largely the result of some intense lake-effect snow squalls coming off Lake Superior. The accumulations occurred over approximately a 96-hour period from November 11-14. Amazing as these totals were they couldn’t compare to the official U.S. record of 75.8” at Silver Lake, Colorado in 24 hours on April 14-15, 1921, or another contender for such: the 78” at Mile 47 Camp in Alaska on February 7, 1963.The purported record snowfall from Alaska is somewhat controversial as I blogged about back on April 1, 2011. In that blog I dismissed the record as an ‘obvious’ error, either on the part of the observer or the NCDC. However, earlier this year, an informal committee of knowledgeable Alaskan-based meteorologists took another look at the record and determined it was, in fact, valid or, at least, possibly valid.
