A deep low pressure system tracked across the Northern Plains in the days following Thanksgiving, and produced widespread heavy snow across most of central and northeast South Dakota. Areas of freezing drizzle occurred on Thanksgiving Day and on Friday the 29th, bringing some spotty icy conditions. Heavy, wet snow then tracked from south to north across the area from the late afternoon of the 29th persisting into the Saturday the 30th. The snow then ended during the morning hours of December 1st. See November 2019 storm data.
Northwest winds gusting to 30 to 50 mph caused areas of blowing snow reducing visibilities, affecting holiday travel. Road conditions deteriorated quickly through the event, with many No Travel Advised statements as well as the closure of Interstate-90 from Chamberlain to the Wyoming border Friday night through Sunday morning, December 1st. Several accidents occurred across the region.  By the time the storm let up in the morning hours of December 1st, anywhere from 6 to 17 inches of snow occurred.
Some snowfall amounts include, 7 inches at Clear Lake, Milbank and Mobridge; 8 inches at Pierre and Sisseton; 9 inches at Miller; 10 inches at Roy Lake; 11 inches at Murdo, Faulkton, and Highmore; and 12 inches at Bowdle and Summit.  Locations with more than a foot include, 13 inches at Presho; 14 inches at Kennebec and Gettysburg; 15 inches at Roscoe and Ipswich; 16 inches at McLaughlin and Eureka; and 17 inches at Aberdeen. Aberdeen's 17 inches was 4 inches off the all-time three-day record of 21 inches from November 23rd to the 25th, 1993.
