Scattered damaging winds, a tornado or two, and isolated severe hail are the likely hazards. DISCUSSION...Deepening convection has been building across southeast IL ahead of a weak cold front in southeast MO. VWP data from PAH has begun to become veered in the low-levels, but adequate 0-1 km SRH exists for low-level rotation amid a very moist and unstable air mass. Convection should continue to increase in a southwest/northeast orientation across the Lower OH Valley through the rest of the afternoon. This should result in more parallel alignment to the deep-layer shear vector. Sporadic damaging winds will probably be the overarching threat, but a tornado or two will be possible, especially with northward extent in southern IN. ...Grams/Hart.. 06/18/2025 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!5s46EpaELNi1zhchw1oIE2FG6eKTmhRsPFF6IhI1C02REMPyk4dny5rQ2vDvRHT8vjwcKLg0n= qZQoVb1zSWyn6hFipI$ for graphic product...
