Isolated large hail and strong wind gusts will be the main hazards with these storms through evening. A severe thunderstorm watch will likely be needed in the next 1-2 hours. DISCUSSION...Mostly clear skies have allowed for strong heating in the upper 80 to low 90s across western/central ND. Boundary layer moisture remains modest across the region, though a plume of 60s dewpoints has spread north and west across portions of the discussion area ahead of a surface cold front over the Canadian Prairies into northeast MT. Steepening midlevel lapse rates are supporting moderate destabilization, while increasing mid/upper southwesterly flow is resulting in 30-40 kt effective shear. Cumulus development is noted across western ND and thunderstorm initiation is expected in the next couple of hours. Supercell wind profiles are present across the region, and isolated large hail and strong wind gusts are expected with this activity. Trends are being monitored and a severe thunderstorm watch will likely be needed in the next couple hours. ..Leitman/Hart.. 07/05/2026 ...Please see www.spc.noaa.gov for graphic product...
