Summer’s finale came with a squall line bringing high winds, flooding rains and tornadoes.
On September 20, 2018 a warm front over northern Iowa lifted north and was associated with a deepening low-pressure system. A large area of rain shifted north over southern and central Minnesota during the morning. Warm air surged into southeast Minnesota by late afternoon. Clusters of strong thunderstorms developed and moved to the northeast across the Twin Cities, causing street flooding. The finale was a squall line of thunderstorms in the evening, bringing a “car wash” style downpour and damaging winds south of the Twin Cities.
Damaging winds ranging from 40 MPH in Eden Prairie up to 70 MPH in Mankato in the squall line were reported. The long line of storms produced tornado-like damage in the cities of Granada, Winnebago, Goodhue, Waseca, Faribault, and Northfield. Many trees were reported down in these areas and structural damage to homes and businesses. The Faribault Municipal Airport was hit hard with flipped planes and flattened structures. The National Weather Service determined that seventeen tornadoes touched down in Minnesota. The strongest being an EF2 tornado that was hundreds of yards wide and tracked for nearly 26 miles near Morristown and Faribault in Rice County. Winds of 120 to 130 mph hit southern Morristown and destroyed several homes. This tornado continued through northern Faribault and destroyed several buildings at the airport.
Schools were canceled due to storm damage in Waterville-Elysian-Morristown areas as well as Faribault, Northfield and Cannon Falls. Sakata Lake State Park was also closed for the weekend of September 21-23 to clean up storm damage. There was even a snow plow brought out in Elysian to clear storm damage.
The heaviest rainfall found for the 24 hour period ending the morning of September 21 was 4.52 inches at a CoCoRaHS volunteer site in Mendota Heights and 4.42 inches at a MNgage volunteer location in south Minneapolis. The Twin Cities International Airport saw 3.28 inches of rain, the 18th largest calendar rainfall in the Twin Cities back to 1871. This is also the 5th largest daily rainfall total to occur after September 1. The 5-day total at MSP of 5.02” is the fourth highest distinct total on record to have occurred after Sep 1. The events ahead of it were in 1900, 1903, and 1934. So this wetness certainly was not without precedent, but it was significant.

Public Information Statement...CORRECTED GRANADA TORNADO National Weather Service Twin Cities/Chanhassen MN 413 PM CDT Fri Sep 28 2018 ...NWS DAMAGE SURVEY FOR 09/20/2018 TORNADO EVENT - UPDATE 2... ...TORNADO COUNT STANDS AT 16... .Update...Following several ground surveys; utilizing high resolution satellite and radar imagery; speaking with local officials, trained spotters, and the general public; and drone and aerial footage it appears there were 16 tornadoes from southern to eastern Minnesota and west central Wisconsin on September 20 2018. This information may be updated as new data becomes available. The difficulty with surveying this event was due in part to many potential tornado tracks amongst widespread wind damage. Since the storms were racing east northeastward around 65 mph, many of the typical indicators for differentiating tornado versus straight line wind damage were not available (e.g. debris deposited westward), particularly across Rice County. Instead, there were areas of enhanced damage on the southern end of the tornado track, with little damage to the north. Most of the damage was to trees, although there were pockets of significant structural damage. Survey teams received numerous accounts of survivors seeking shelter immediately after receiving the Tornado Warning via a Wireless Emergency Alert notification. Some of these people later had their house or other structure significantly damaged or destroyed. It is of the opinion of the surveyors that this was one big factor for the lack of fatalities or injuries. The NWS would like to thank all the spotters, local officials, broadcast television, local media, volunteer and media drone operators, and citizens that contributed to the sharing of information before, during, and after the event. Overall, there were six EF0s, nine EF1s, and one EF2. .Granada, MN Tornado...
