Multiple, long-lasting, large hail-producing thunderstorms bombarded the Twin Cities Metropolitan Area and neighboring counties during the evening and overnight hours, with hail, gusty winds, intense rainfall, and non-stop lightning and thunder.

The activity came in two waves. The first developed right around sunset on Sunday August 9, as compact but intense thunderstorms formed repeatedly across the southern Twin Cities, especially near Chaska, Chanhassen, Bloomington, and Burnsville. These storms lasted 2-3 hours and moved little, producing pockets of large hail and heavy rainfall. Reports of half-dollar to golf ball-sized hail were common, with hail the size of tennis balls photographed in Victoria.

The second, larger, and longer-lasting wave of severe thunderstorms formed around 11 PM in Wright County, and spread southeastward very slowly over the next several hours. These intense supercell thunderstorms grew to the size of 2-3 counties, and produced multiple distinct cores of ping pong ball to tennis ball-sized hail, affecting areas from near Montrose and Buffalo in Wright County, to Loretto, Maple Plain, and Edina in Hennepin County.

The second wave of storms eventually moved into areas affected by the first wave, producing more large hail, along with winds of 50-60 mph. The Twin Cities International Airport recorded a wind gust of 61 mph; Flying Cloud recorded a gust to 59 mph. Even areas not hit directly by the strongest storms experienced vivid, often continuous lightning. Many observers noted a "roaring" sound caused by the unending thunder.

The storms formed in a very unstable environment, likely along corridors that had been disturbed by rain and thunderstorms earlier in the day. These corridors allowed strong thunderstorms to regenerate and affect many of the same areas multiple times. Buffalo in Wright County received golf ball-sized hail three separate times. Chanhassen had nearly non-stop activity from 7:45 to 10 PM, and again between 1 and 330 AM. The repeat activity resulted in rainfall of 2-3 inches in Wright, Hennepin, and Carver Counties, with observers near Chaska, Chanhassen, and Eden Prairie reporting 4-5 inches of rain. The National Weather Service forecast office in Chanhassen led the pack with an official total of 5.53 inches.

Outside of this activity, it had been a stormy weekend in Minnesota. Strong thunderstorms produced large hail and small tornadoes on Friday evening near Park Rapids, Walker, Leech Lake, and Hackensack, before spreading heavy rains eastward towards the Arrowhead region overnight. Similar and nearby areas were affected again on Saturday with large hail and damaging winds, while additional severe thunderstorms in western Minnesota produced a 72 mph wind gust at Canby, with other damage to large trees reported near Granite Falls. Trees and power lines were damaged from other storms in Cannon Falls. Scattered strong to severe thunderstorms continued Saturday night into Sunday across parts of the state, and even prior to the severe thunderstorms in the Twin Cities area Sunday evening and overnight, northwestern Minnesota had been hit hard, with a 77 mph wind gust recorded in Thief River Falls Sunday afternoon, and damages reported in Kittson and Beltrami Counties.

Following is a round-up of rainfall reports from the National Weather Service office in Chanhassen.
