After sitting out the last big storm as snow and winds slammed northern areas, this time it was southern Minnesota's turn.

Heavy snows, accumulating up to 21 inches, clobbered areas from the southwest corner of the state, up into the central and southern Twin Cities area. The snow, coming on a Friday evening, shut down traffic for times on I-35, caused over 300 accidents, over 300 spin-outs, and over 20 jackknifed semi trailers. 

Bands of light, then moderate, and eventually heavy snow set up over southern Minnesota on Friday December 10, 2021, lasting right through the evening and into the early morning of Saturday December 11th. The snow reached peak intensity between 3 and 9 PM, with snowfall rates approaching two inches per hour at times. The winds picked up late in the evening, with some gusts over 30 mph just  after the heaviest snow had moved into Wisconsin, but while accumulating snow still was falling. From Redwood Falls and the Twin Cities area on south to the Iowa border, the afternoon and evening hours were marked by reduced visibilities--often under 1/4 mile--along with snow-packed roads and lightly sculpted snow drifts forming in open areas.

The snow formed initially north of a warm front, several hundred miles in advance of a strong low-pressure system in southwestern Kansas. As the low moved east-northeastward towards Milwaukee, the snow intensified and formed into a pivoting arc, stretching from Nebraska, into southern and eastern South Dakota, and through the southern 1/4 to 1/3 of Minnesota. A particularly intense band of snow formed near the Minnesota River in the southern Twin Cities area. This snow band remained nearly stationary, and after it weakened, was replaced a larger, even more intense band that lasted for much of the evening. 

The repeated and prolonged concentration of heavy snowfall led to narrow stripe of especially large snowfall totals. The highest accumulations, generally in the range of 12 to 18 inches, stretched from Sibley and Le Sueur Counties, into the southeastern half of the Twin Cities. Some individual totals included 21 inches on the east side of St. Paul near Battle Creek, 20 inches at Woodbury, 19 inches at Lakeville and Prior Lake, 18.9 inches in Inver Grove Heights, and 18.5 inches in western Bloomington. These were the highest storm totals in the Twin Cities area since the great Thunder Blizzard of April 2018, and the highest 24-hour totals since the infamous "Final Domebuster" storm, 11 years earlier, almost to the date.

Too many cities and towns to name reported only slightly lower accumulations, but the focus of the heaviest snow along a narrow axis of strong lift produced a sharp gradient in the amounts received. The MSP airport received a healthy 11.8 inches from the storm, but was only a few miles north and west of the highest totals in the state. On the north side of town, amounts struggled to reach six inches. Snowfall totals of six inches or more covered roughly the southeastern 1/3 of the state. 

The same low pressure system that produced the heavy snow here in Minnesota also produced deadly tornadoes and severe thunderstorms in Arkansas, Illinois, Kentucky, Missouri, and Tennessee. Although it is not unusual for Upper Midwest winter storms to be associated with severe weather outbreaks well to the south, the tornadoes in Illinois in particular were unusually far north for this late in the season.

 

Below are county-by-county snowfall reports, gathered by the National Weather Service forecast office in Chanhassen.
