This pattern reminds me an awful lot of January 77. There's a misconception that we had a lot of snow that month but the cold was the real story. It is still the coldest month on record at GSP. The highest temperature recorded at GSP for the month was 50 degrees. 77/78, 78/79, and 79/80 were the trifecta for SE winter storms.
01/3/77 - 1"-2" of snow in the upstate
1/10/77 - Superbowl Sunday, 3"-4" in the upstate, brutal cold the following week
1/15/77 - ice storm
1/17/77 - famous (or infamous) cold wave. Temps in the low to mid teen in the upstate during the day.
1/24/77 - 5" of snow
February and March turned warm with above normal temps, so it was really a 4 week stretch that changed the record books.
Side note, February 80 is still the coldest February on record in the upstate.
