Upper troughing is expected to extend from the High Plains into central Mexico early D4/Sunday morning. A series of shortwave troughs are expected to progress through this trough as it gradually shifts eastward. The lead shortwave in this series is expected to move across the Southeast on D5/Monday. Modest moisture will be in place and some isolated thunderstorms are possible over the Southeast as this shortwave moves through. Most of the stronger mid-level flow will lag to the west of this wave, but some overlap between the modest buoyancy and shear could support a low-coverage severe potential. By D6/Tuesday, the evolution of these shortwaves will likely have resulted in the development of a mature mid-latitude cyclone centered over the Lower MO Valley/Mid MS Valley vicinity. As this system matures, an attendant cold front is expected to push eastward across the TN Valley and Southeast on D5/Monday and D6/Tuesday. Buoyancy will likely be limited ahead of this front, but some isolated thunderstorms are still possible, particularly across the Southeast.
