Hail and damaging winds are likely initially but the tornado threat is expected to increase into the evening. A WW will be issued by 23z DISCUSSION...As of 22 UTC, visible and radar imagery showed convection intensifying over the western NE Panhandle. The environment downstream has recovered quickly in the wake of earlier clouds while maintaining robust surface moisture with dewpoints in the upper 60s, increasing to the low 70s F farther east. A very unstable environment (MLCAPE 3000-4000 J/kg) is in place with deep-layer shear supportive of organized supercells. The ongoing storms should continue to mature with a mixed/cluster supercell mode expected to spread eastward. Hail and damaging winds are likely with supercells initially where higher cloud bases are expected. However, as storms move into the richer moisture, backed low-level flow will support a tornado risk. This may increase further this evening as a forecast 40+ kt low-level jet expands low-level hodographs. ..Lyons/Smith.. 06/09/2026 ...Please see www.spc.noaa.gov for graphic product...
