Strong southwesterly deep-layer flow will overspread the region ahead of an upper trough pivoting east across the Plains toward the Mid-MS Valley. At the surface, a cold front will be oriented from the OH Valley to southern AR and central TX. Ahead of the front, rich Gulf moisture will be in place across southern and eastern TX into the Lower MS Valley eastward toward AL. Moderate to strong destabilization is expected across the warm sector ahead of the southward-sagging cold front. Supercell wind profiles are evident in forecast soundings. However, given linear forcing along the front and deep-layer flow largely parallel to the boundary, it is uncertain if discrete storms will be possible. Nevertheless, severe potential is still expected with clusters and linear segments given the favorable thermodynamic environment and strong vertical shear. ...Day 5/Thu - South TX and parts of the Southeast... Some severe potential could persist into Thursday across south TX as the cold front continues to develop southward across a very moist and unstable airmass. However, large-scale ascent may be limited as forcing associated with the eastern U.S. upper trough focuses well northeast of the region. Shortwave upper ridging also may overspread region ahead of an upper low/trough over northwest Mexico. Additional strong or severe storms will be possible across parts of the Southeast toward the Carolinas and Mid-Atlantic as the cold front shifts east across that region. However, widespread showers/thunderstorms and cloud cover may limit destabilization, and convection could become anafrontal by this time. ...Days 6-8/Fri-Sun... Spread beings to increase across model guidance by the weekend, though mean upper troughing across the East seems likely to persist. This typically would not be ideal for severe potential. However, an upper shortwave trough is forecast to move across the southern Rockies into the southern Plains. Forecast guidance varies widely with the timing and evolution of these features however, and predictability is low. ..Leitman.. 05/03/2026 = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
