High humidity and an approaching cold front could combine to generate severe weather in parts of Arkansas on Wednesday.

The Storm Prediction Center says there is a 30% chance for severe storms in the area between Little Rock and Memphis, Tenn., as a cold front slices through humid air. Severe storms are also possible to a lesser degree into the lower Ohio Valley and the Missouri Bootheel.

Forecasters say wind shear within the atmosphere, where winds move in different directions at different heights, could interact with the moist air and lead to the development of supercells from parts of the Ozark Plateau to the mid-Mississippi Valley. Later Wednesday, a squall line could generate high winds and hail.
