A cold front will push through Arkansas from the Plains on Thursday. Ahead of the front, very warm conditions/well above normal temperatures will exist, creating a very unstable environment.
A broken line of scattered strong to severe thunderstorms are expected to develop across the northwest counties Thursday afternoon. The line is then expected to move towards central and northeastern locations Thursday evening and night. There are indications the line will gradually weaken after the sun sets, and daytime heating is lost.
Large hail and damaging winds are the primary concerns, especially across northern and extreme western parts of the state. A low, but non-zero tornado chances exists across the northeastern half of the state.
