What happened
The episode as NWS FGF wrote it up.
Showers and weak thunderstorms continued across most of eastern North Dakota and the northwest quarter of Minnesota on the 9th of August. With an upper level low pressure system over the area, the showers and storms moved in a counter-clockwise manner. By the early afternoon, a small cluster of storms between Devils Lake and Jamestown began to strengthen. This cluster of storms moved into Barnes and Cass counties of North Dakota and Clay County of Minnesota, producing large hail and at least one funnel cloud.

Area forecast discussion, Aug 9, 1:50 PM CST, 5 minutes before
Area Forecast Discussion National Weather Service Grand Forks ND 250 PM CDT Wed Aug 9 2017 .SHORT TERM...(This evening through Thursday) Issued at 245 PM CDT Wed Aug 9 2017 Main challenge in the short term will be Thunder potential/coverage and severity. Upper low will continue to propagate east along the international border region. Impulses rotating around the low will provide upper support for convection to continue into the evening hours. Best organization at this time and supported by CAMs and high resolution model guidance will be along trailing cold front roughly bisecting the forecast area from ne- sw and more spotty vcnty sfc low over the northern fa. Shear and mid level lapse rates not impressive however sufficient instability and cape for a few storms to approach severe limits. Probably more likely will be funnel clouds associated with upper low. No reports yet but SPS may be warranted if calls start coming in. Guidance indicating that convection should weaken with loss of heating however with upper low in the vicinity showers may linger overnight and have pops going accordingly. Drier air still aways back into Sask so lows should not be too far off from last night. Lingering pops warranted across most of the fa tomorrow until upper low exits the region. Any additional rain amounts will be light and mainly east of the valley. With cooler column in place temperatures will hold mainly in the upper 60s to mid 70s depending on degree of solar. .LONG TERM...(Thursday night through Wednesday) Issued at 245 PM CDT Wed Aug 9 2017 By Thursday night, clouds will be clearing from northwest to southeast as high pressure moves in from Manitoba. For Friday, high pressure takes hold across Minnesota and the eastern Dakotas, bringing more dry weather most areas for the weekend and into early next week. There are some small chances for scattered showers and storms as a few weak disturbances pass through the southern half of the Red River Valley and lakes country in west central Minnesota Saturday through early Sunday, but no signal for widespread or heavy rain events indicated. As the Northern Plains region remains in northwest flow aloft through early next week due to a blocking ridge in the West, temperatures will be below to near normal values, remaining in the upper 70s to lower 80s. Models are in decent agreement regarding a chance of more widespread rain as a system moves in for the middle of next week, but this is still pretty far out. && .AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon) Issued at 1254 PM CDT Wed Aug 9 2017 Main challenge was mention of tsra across the Fa this afternoon into the evening. At this time it looks like eventually favored location for storms will be along and south of highway 2 and mentioned tempo groups for T later this afternoon. Once convection moves through this evening could see some wrap around MVFR cigs tonight. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...None.
