Storms will be ongoing at daybreak across the eastern portion of Texas before shifting into a warm and moist airmass over southern Arkansas, Louisiana and Mississippi during the daytime hours.
The threat for severe storms will move into Houston, Shreveport, New Orleans, Jackson and even Mobile by Sunday afternoon.
