Charlotte received nearly 5" of snow on March 2, 1978. There were several small snow events during the last ten days of February 1978.
2/1978, which is included in my analysis, was the coldest of the 9 very strong phase 7 MJO events. So, it was a bit of an exception as it was the only one of the 9 very strong phase 7 events that was cold in the SE.
