What happened
The episode as NWS MPX wrote it up.
During the morning of Friday, July 12th, a small complex of storms developed in South Dakota, and moved eastward into west central Minnesota before noon. The storms continued to march across southern Minnesota, almost in a straight line from near Redwood Falls, eastward into the southern part of the Twin Cities metro area. Several wind gusts of 50 to 55 mph occurred, and a wind gust of 59 mph was measured in Scott County. Sporadic trees were blown down also along the path, but the majority of the wind damage was minor. The Redwood Falls airport measured a wind gust of 55 mph at 1047 LST. There was also a measured wind gust of 52 mph at the Minneapolis/St. Paul airport at 1234 LST, and a measured wind gust of 50 mph near Elko/New Market at 1226 LST.

Area forecast discussion, Jul 12, 4:59 AM CST, 5 hours 36 minutes before
Area Forecast Discussion...UPDATED National Weather Service Twin Cities/Chanhassen MN 559 AM CDT Fri Jul 12 2019 .SHORT TERM...(Today through Saturday) Issued at 428 AM CDT Fri Jul 12 2019 A cold front is pushing across northern Minnesota early this morning. Isolated thunderstorms have been firing along it periodically overnight. This trend is expected to continue today and this evening as the front sags southeast. The best forcing for ascent will remain northeast of the area and displaced from the greater instability south of the front. Convergence along the front isn't expected to be impressive either; therefore, coverage will remain 15-30 percent, highest expected across WI nearest to the best deep layer forcing. Surface dew points in the upper 60s to near 70 will be pooling along the front and contribute to 1500-2000 J/kg of CAPE. In addition, mid level westerlies in the 40-50 kt range will bring bulk shear values of 35-40 kt in the warm sector. The instability/shear parameter space suggests supercells (and line segments given the largely unidirectional flow) will be possible and capable of producing large hail and damaging winds. The isolated diurnal activity should wane after sunset, however a modest low level jet will develop with the terminus over southwest MN. This will likely generate additional cells along the stalled front across far southern MN into northern Iowa overnight into early Saturday. By late morning Saturday, the storms will shift southeast and the rest of the day will be dry. Thermal ridging along and south of the front should bring highs into the upper 80s today, with a 90 possible here and there. A slightly cooler air mass will push in Saturday, but light or calm winds Saturday should allow for a superadiabatic profile and we should reach the mid or upper 80s again. .LONG TERM...(Saturday night through Thursday) Issued at 428 AM CDT Fri Jul 12 2019 Not too much has changed with respect to the longer term forecast. A broad upper ridge over the central US will work into the area over the weekend, then flatten slightly through midweek (although we'll be well entrenched in the heat and humidity). A decent upper trough is forecast to dig into the northwest US by most of the guidance Friday into next weekend, which would help to re-amplify the upper ridge across our area, and perhaps result in us seeing our warmest temperatures of the year at the end of the week. However, spread in the guidance (and ensemble systems) increases quite a bit once we get beyond Wednesday, so stuck fairly close to the consensus forecast at this point. That being said, above normal temperatures are expected through the week, with periodic chances for showers and thunderstorms. It's still a bit tough to have much confidence in the timing and location of precipitation chances since much will depend upon weak shortwaves moving around the upper ridge (and resultant MCS activity). Given the instability that will be in place, some severe weather is certainly still possible over the course of the week, with shear looking best around midweek when the upper jet gets a bit closer to the area once again. && .AVIATION...(For the 12Z TAFS through 12Z Saturday morning) Issued at 559 AM CDT Fri Jul 12 2019 VFR conditions expected through the period. Isolated thunderstorms may develop along a cold front today, mainly across eastern MN into western WI. Additional storms could fire near and south of MKT overnight tonight. Otherwise, south winds will veer westerly this afternoon and then northerly overnight, becoming light and variable into Saturday. KMSP...Left any mention of TSRA out of the TAF due to the low coverage expected. Best chance would be east of MSP. /OUTLOOK FOR KMSP/ Sun...VFR. Slight chance of -TSRA. Winds SSW 10 kts. Mon...VFR.
