DISCUSSION...An expansive area of storms has developed across North Dakota and northwest Minnesota within a broad region of isentropic ascent. 1500 to 2000 J/kg MUCAPE and effective shear of 30 to 35 knots (per SPC mesoanalysis) will support some organization, including the potential for some supercell structures. Overall, expect mostly sub-severe high-based storms, but a few of the stronger storms may be capable of large hail. No watch is expected. ..Bentley/Smith.. 08/03/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FGF...ABR...BIS...
