A warm front extended from a developing and strengthening surface low pressure area over west-central Louisiana across southern Mississippi late Sunday morning.
Rich gulf moisture was flowing north across areas along and south of the boundary. With increasing instability and shear Sunday afternoon and evening, some storms will be capable of rotating and producing isolated tornadoes and damaging winds.
The severe storm risk is confined to areas south of Interstate 20.
The threat for severe weather and heavy rain is expected to wind down Sunday night with the passage of the surface low. Although, light rain is forecast to continue across portions of the state on Monday before drier air filters in on Tuesday.
