The Storm Prediction Center says there is a slight risk of severe weather in parts of Arkansas, Kansas, Missouri and Oklahoma on Thursday. The greatest risk will be in western Arkansas, southwestern Missouri and eastern Oklahoma.
Forecasters said heating within a 100-mile-wide corridor should make the atmosphere unstable ahead of an approaching cold front. Storms could develop from an area roughly from Kansas City to the Arklatex.
The forecasters said data suggest supercells could form and that some could produce large hail and possibly tornadoes, especially between southwestern Missouri and the Red River.
The threat will decrease overnight Thursday, but there's also a slight risk of severe weather Friday for an area from the Arklatex to the southern Appalachians and north into the Missouri bootheel and southern Kentucky.
