Minneapolis and Green Bay were two of the many communities significantly impacted by the heavy snow and blizzard conditions that blasted the north-central United States Friday into Sunday night.

The worst of the snowstorm is winding down in the upper Great Lakes as the traditional workweek begins.

Thundersnow and sleet were reported on Friday evening near Minneapolis as the storm ramped up in the area.

Heavier snow ensued on Saturday afternoon and evening with visibility reduced to a quarter mile or less for six-consecutive hours. Thundersnow also occurred during the height of the storm.

Mother nature continues to troll us.

Saturday became the second-snowiest April day on record for Minneapolis. A total of 11.1 inches was measured, second only to the 13.6 inches that fell on April 14, 1983.

The snow from this storm makes this month the city's snowiest April on record. April 1983 previously held the record with 21.8 inches.

The snowstorm forced the Minnesota Twins to postpone the entire three-day series against the Chicago White Sox that was originally scheduled from Friday to Sunday.

As of 1 a.m. CDT Monday, a storm total of 23.7 inches of snow was recorded in Green Bay, making this the second largest snowstorm in April history. The largest April snowstorm dumped 29 inches of snow on the city in 1888.

Flight operations resumed Sunday morning at the Minneapolis-St.Paul International Airport following Saturday's blizzard. However, airline passengers faced additional lengthy delays on Sunday.

The blizzard also entered history books in Green Bay as the second largest snowstorm. A total of 23.2 inches had fallen as of Sunday afternoon. The city's airport reported visibility down to zero miles frequently from the midday to the early afternoon hours.

Very poor road conditions! If you must travel, make sure to slow down, allow for extra travel time, and take an emergency car kit! #wiwx pic.twitter.com/6Mtx0t2rNu — NWS Green Bay (@NWSGreenBay) April 15, 2018

Amid the heavy snow, the roof over a pool area at an Econo Lodge in Ashwaubenon, located southwest of Green Bay, collapsed on Sunday morning. No injuries were reported, according to WBAY.

The No Travel Advisory that was in effect for Sioux Falls, South Dakota, was lifted on Sunday morning, according to the city's police department.

The visibility was down to a few hundred feet in blizzard conditions, with winds gusting between 40 and 50 mph with thunder and lightning around Sioux Falls during Saturday morning. The wind-swept snow persisted into Saturday night.

The 13.7 inches that fell on Saturday makes April 14 the snowiest April day in Sioux Falls, surpassing the previous April snow record of 10.5 inches from April 28, 1994.

The snowstorm first blasted Nebraska late Friday night and into early Saturday morning.

Thousands lost power on Saturday as Nebraska Public Power District restoration crews worked through intense conditions.

Officials warned against traveling in western Nebraska on Friday night as snow closed several roads in the area, including parts of Interstate 80.
