Several severe thunderstorms developed in northeast South Dakota during the late afternoon of Friday, July 17th. These storms moved slowly initially across northeast South Dakota where severe wind gusts, very large hail and a tornado occurred. ||After 730 PM CST, these severe storms began to bow out across west central Minnesota from Morris, southwest to Ortonville. Severe wind gusts were reported in Madison to Appleton City as the bow echo began to accelerate eastward across southern Minnesota.||Numerous reports of downed trees, power lines and occasional hail occurred from the South Dakota, Minnesota border eastward to the Twin Cities, and into west central Wisconsin. ||Damage was more sporadic in western Minnesota, but became more widespread in eastern Minnesota as a more intense bow echo developed. A widespread area of trees and power lines were blown down across the Twin Cities metro area, with some areas measuring wind gusts up to 61 knots. ||One of the bow echo segments produced a brief tornado west of Watertown, where a storm survey indicated an EF1 occurred.||Another significant wind damaged area was in Goodhue County where winds up to 85 mph were estimated based on a local survey. ||At one point during the storm, 225,000 people in Minnesota were without power according to Xcel Energy.

The evening of Sunday, July 5th, a line of thunderstorms developed along a frontal boundary from west central Minnesota, northeast to the arrowhead region. These storms slowly moved southeast across west central and central Minnesota by midnight. By 2 to 3 am CST, numerous thunderstorms began to develop in east central Minnesota, ahead of the main line. ||As additional thunderstorms congealed with the main line, deep moisture continued to surge into southern Minnesota, with the effect of high precipitable water values, rainfall rates increased to 2-3 inches per hour. These storms trained and redeveloped in the southern and southeastern Twin Cities metro area, and moved eastward into west central Wisconsin. Several hours of moderate to heavy rainfall occurred from northern Dakota and southern Washington Counties, eastward into Wisconsin during the early morning hours of Monday, July 6th.||Storm totals ranged from 4-5 inches in northern Dakota County and southern Washington County. Heavy rains overflowed a pond, and caused flash flooding at Highlands Park in Cottage Grove. ||The following are some of the higher rainfall totals from Monday morning, July 6th.||Burnsville 4.73 inches. |Farmington 4.60 inches.|Cottage Grove 4.40 inches. |West St. Paul 4.25 inches.

A line of thunderstorms developed early Thursday morning, September 17th in eastern Minnesota, near the Twin Cities. These storms produced very heavy rainfall, gusty winds and some hail. The largest hail stone was quarter size near Crystal. Several thunderstorms moved across northern Dakota, southern Ramsey, and parts of western Washington Counties, and produced up to 2-3 inches of rainfall in less than 2 hours. These rainfall amounts and high rainfall rates, led to flash flooding along several highways during the morning commute in the southeast Twin Cities metro area. Several cars stalled in flood waters as they moved into areas of 2-3 feet of water along I-35E near St. Paul.

Overnight thunderstorms and an associated lightning strike caused the cross atop St. Helena???s Catholic Church to crash to the ground. The cross was made of limestone, which had been on the church for 75 years. Damage also occurred on the marble steps at the entrance to the church. Nobody was hurt, though the impact of the falling rubble could be heard as far as two blocks away.

Waves of severe thunderstorms moved southward across east central Minnesota, and west central Wisconsin during the afternoon and evening hours of Monday, June 29th. There were also several hail swaths that affected portions of the northwest, and western suburbs of the Twin Cities metro area based on the SHAVE project, trained spotters and the general public. ||Specifically, one complex of severe storms developed during the early-mid afternoon hours near the Elk River, and drifted southward producing large hail from Elk River, to Rogers, Maple Grove, Plymouth and Eden Prairie. ||The second wave of severe thunderstorms moved across far east central Minnesota and again produced large area from near Rush City, North Branch, south across the heart of the Twin Cities metro area before dissipating around sunset.

Several thunderstorms developed across the western Twin Cities metro, into east central Minnesota, between 300 and 330 PM LST. One storm developed over the National Weather Service Office in Chanhassen, MN and produced large hail. There was also siding damage to homes just south of the National Weather Service Office in Chanhassen, which reported up to two inches in diameter for hail size. As this storm moved off across the southern part of the Twin Cities area, most of the hail was measured up to the size of nickels.||Another severe thunderstorm developed in the northwest part of the Twin Cities, near Brooklyn Park, where windows were blown out, and then began to move rapidly eastward across the northern and eastern Twin Cities area. Numerous reports of large hail (up to 1.25) and damaging winds were reported along the storm path from near Crystal, Robbinsdale, and Golden Valley, eastward to North Minneapolis, Columbia Heights, Saint Anthony and Arden Hills. Another swath of large hail (up to golf ball size) occurred from near White Bear Lake, eastward to Stillwater. Some of the hail was measured up to a foot deep in some areas. These storms moved quickly eastward into west central Wisconsin and produced more severe hail and damaging winds. ||A secondary line of thunderstorms developed along the Minnesota, Iowa border and produced damaging winds near Albert Lea where power lines were blown down.
