DISCUSSION...Surface analysis and satellite imagery show the warm front continues to rapidly move north across MO, with extreme instability developing. Incipient storms are noted on radar just ahead of the cold front over southwest MO and northwest AR, and these will likely become supercells with time. Additional storms are likely through the afternoon overspreading the rest of MO, northern AR and western IL. Very large and damaging hail appears likely, with a few tornadoes as well. ...Jewell/Mosier.. 05/16/2025 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!--K5IBpADXMfXuYWkWgaV67KcplYJ9wgtfjllRQkcgbbO93H2rpTGaK08EJaqnXZ0P7qiC7iX= bdu5T4i8197z0zam3M$ for graphic product...
