Severe thunderstorm potential appears low on Thursday. ...Discussion... An upper trough will migrate across the Northeast on Thursday, while a second upper trough digs southward across the northwestern U.S. Stronger flow associated with these features will remain confined to the northern Rockies vicinity and over New England. High pressure will build over the Midwest and Mid-Atlantic region in the wake of a prior cold frontal passage. A seasonally moist boundary layer will be in place from the central/southern High Plains through the southern/southeastern U.S. Pockets of stronger heating and modest destabilization across the warm sector will support scattered thunderstorm development. However, generally weak vertical shear will limit organized severe potential, especially given a lack of focus for severe storm development. The exception may be with a strong storm or two across the central/southern High Plains in a post-frontal upslope flow regime. A stalled front will become diffuse across the area on Thursday, but vertically veering wind profiles could result in some modestly enhanced vertical shear. Some guidance shows early day convection and cloud cover across this area, resulting in uncertainty in storm coverage during the afternoon and evening. Furthermore, lapse rates will remain modest and low-level flow will be weak, precluding severe probabilities at this time. ..Leitman.. 09/08/2026 $$
