As a cold front approaches western Mississippi early tomorrow, a line of thunderstorms will develop along the front. Additionally, there is the potential for discrete thunderstorms to develop independently ahead of the frontal boundary. Hail, high winds and locally heavy rainfall are all possible with these storms. Tornado development cannot be ruled out as these storms pass.
Storm development is expected to begin in the western portions of Mississippi around daybreak, from 6am through noon. Areas along the Natchez Trace corridor should see storms move through between 11am and 5pm, and finally areas of southeastern Mississippi will see the front pass through between 3pm and midnight. The greatest potential for severe weather development is expected to be south of a line from Grenada, Mississippi, to Morehouse Parish, Louisiana. While this indicates less risk for the western portion of the Mississippi Delta (Bolivar, Sunflower, Washington counties), readers in those area should remain alert to developing weather conditions.
