An extreme, late-season winter storm struck Minnesota from April 13-16, 2018, producing everything from thunderstorm wind damage to prolonged blizzard and whiteout conditions.The storm came in three distinct rounds, each separated by anywhere between four and eight hours.

The first round began on the morning of Friday April 13th, as severe thunderstorms tore into far southwestern Minnesota from South Dakota, knocking over power poles, damaging farm equipment, and producing a wind gust of 78 mph near Rushmore in Nobles County. Precipitation accompanied by 45 mph wind gusts then spread across the southern half of the state, with a mix of rain, sleet, freezing rain, and eventually snow, resulting in 1-4 inches of accumulation from the Twin Cities northward, and up to 8 inches near the Minnesota River in western Minnesota, before ending just after midnight.

The next round began with a vengeance Saturday morning as a wave of even heavier precipitation and strong winds worked into southern Minnesota from Iowa. This round was the “main event” of the storm for all but northeastern Minnesota, with lightning, thunder, multiple consecutive hours of heavy snow, and winds gusting again above 40 mph, creating whiteout conditions throughout southern Minnesota, including in urban areas. The severity of the storm prompted the National Weather Service to expand Blizzard Warnings through the entire Twin Cities Metropolitan Area for the first time since the infamous Halloween Blizzard of 1991. After producing 8-14 inches of snow on top of what had already fallen on Friday, the snow from this round began to wind down from south to north on Saturday evening.

The final round on Sunday produced an additional 2-6 inches of snow across southern and eastern Minnesota, but was much more ferocious in the Duluth area, where over a foot of snow accumulated as winds gusted to near 50 mph in the harbor, and to 40 mph on the hills around town.

When all was said and done, an unusually large area of Minnesota, covering about 20 percent of the state, had over a foot of snow. Roughly half of the state had six inches or more, and numerous NWS cooperative observers reported three-day totals in excess of 15 inches. The largest “official” reports included 26.5 inches at Canby in Yellow Medicine County, 21.4 inches at Madison, 19.6 inches at Lake Wilson, and 19.5 inches at Milan. Numerous observers with the CoCoRaHS network similarly recorded amounts between 19 and 21 inches.

The blizzard made travel nearly impossible. It grounded flights at Minneapolis-St. Paul International Airport for over seven hours and caused over 600 accidents, nearly 1200 spin-outs, and approximately 20 jackknifed semi trailers. The storm also collapsed the 77-foot-high dome of the Vadnais Sports Center, and forced three consecutive Minnesota Twins home games to be postponed for the first time since Target Field opened.

In the Twin Cities, the snowfall total of 15.8 inches was the largest to occur so late in the season, broke the storm-total accumulation record for April, and made April of 2018 the snowiest April on record. Additionally, by holding temperatures to the 20s or very low 30s during Saturday and Sunday, the storm enabled St. Cloud, Duluth, Rochester, and the Twin Cities to break records for the lowest high temperature of the day.
