DISCUSSION...Isolated thunderstorm development is underway over southwest ND into northwest SD -- generally focused along a weak east/west-oriented stationary boundary. This activity is developing along the northern edge of a plume of weak surface-based instability, and this weak instability is the main mitigating factor for a more robust severe-storm risk. However, proximity forecast soundings indicate strong deep-layer shear (around 60 kt of effective shear) -- characterized by a long/straight hodograph. This wind profile may support brief updraft organization (with transient midlevel rotation) -- capable of producing marginally severe hail (up to 1 inch) and locally strong/damaging winds (45-60 mph) for the next couple hours. Overall, the weak instability should limit the severe threat. ..Weinman/Majchrowski/Bunting.. 06/07/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...ABR...BIS...UNR...
