The episode as NWS BIS wrote it up.
Two areas of thunderstorms developed during the afternoon and early evening hours. The first area was over south central North Dakota into the James River Valley along a slow moving frontal boundary. The second area was over southwest North Dakota ahead of a progressing surface trough. The largest reported hailstone was two inches in diameter, and fell in Dickey County. The strongest reported winds were estimated at 70 mph, which caused tree damage in LaMoure County. In addition, over the Dickinson area copious amounts of small hail fell, along with heavy rain. Although the largest hailstones were the size of a nickel, the hail piled up closing some streets and stranding some cars. The hail also combined with gusty winds to create hail drifts, some a few feet high.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Bismarck, ND wrote its last area forecast discussion before the first event at Jun 20, 1:19 PM CST, 1 hour 46 minutes earlier.
Area Forecast Discussion National Weather Service Bismarck ND 219 PM CDT Mon Jun 20 2022 .SHORT TERM...(This evening through Tuesday) Issued at 219 PM CDT Mon Jun 20 2022 The main story for the short term is additional chances for widespread severe weather from this afternoon into the overnight hours. Presently, showers and occasional thunderstorms are occurring along and west of a nearly stationary frontal boundary that is essentially draped from northeastern ND down through Stutsman, Logan, and McIntosh counties. The atmosphere is very moist and unstable this afternoon along on the warm side of the frontal boundary. Boundary layer dewpoints sit in the upper 60s over the James River Valley, along with MUCAPE values of over 2000 J/kg, while 0 to 6 km Bulk Shear values are in excess of 60 kts. This is a primed environment for very large hail that could be up to two inches in size during the afternoon. That said, there is some question as to whether or not convection will blow up over the James River Valley, or if it will slide east of the forecast area before rapid intensification begins this afternoon. The aforementioned nearly stationary frontal boundary will finally be kicked eastward late this afternoon and evening, thus becoming a more progressive cold frontal boundary, as a trough west of the forecast area lifts up through the northern Plains. As alluded to earlier, this will push ongoing convection eastward. The consequence is that this trough itself is already forcing thunderstorms southwest of the forecast area. As it lifts up through the Dakotas, lines of thunderstorms moving into southwestern ND later this afternoon will track northeastward through the evening and into the overnight hours. While the environment won't be as favorable in western and central ND this evening compared to parts of central ND this afternoon, there is still enough instability, shear, and moisture to where severe thunderstorms are expected. By Tuesday, the pressure gradient will tighten as surface low pressure moves off to the northeast. As a result, cooler temperatures, of which are actually near average for this time of the year, and gusty winds out of the northwest are expected for Tuesday. Winds may approach Advisory criteria during the afternoon. Otherwise, a few showers and thunderstorms may linger in northern parts of the state during the day, but by then, the severe threat will have subsided. Conditions will be mostly dry across the forecast area Tuesday night. .LONG TERM...(Tuesday night through Monday) Issued at 219 PM CDT Mon Jun 20 2022 The period starts out with a lowly amplified ridge moving over the region, while high pressure resides at the surface over eastern South Dakota/Nebraska and gradually meanders eastward. As a result, mostly dry conditions and a warm day on Wednesday, followed by a hot day on Friday, are expected. By Thursday night, models are coming into better agreement that a trough off a south Canadian low will cross through the region. This could bring a return of shower and thunderstorm activity, as well as a return to cooler temperatures (highs in the 70s) for the weekend. && .AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon) Issued at 105 PM CDT Mon Jun 20 2022 Showers and thunderstorms, some potentially severe with large hail and very strong winds, are possible at all TAF sites this afternoon and evening. However, exact timing remains uncertain at most sites and therefore have generally gone with rain showers and vicinity thunder. Higher confidence exists at KJMS where thunderstorms already exist to the west and northwest and will likely pass over by mid-afternoon. Winds will remain relatively light until Tuesday morning when they become gusty out of the northwest. However, erratic winds with reduced ceilings and visibilities are expected with any showers and thunderstorms that pass over a terminal. && .BIS WATCHES/WARNINGS/ADVISORIES...
