A mid-level trough will persist across the central CONUS through early next week, before gradually weakening in favor of more amplified, progressive upper troughs. Through the beginning of next week, a few impulses ejecting into the northern Plains may be accompanied by enough buoyancy and vertical wind shear to support an isolated severe threat. However, confidence is too low to delineate a more focused severe threat at this time. Likewise, there is a lack of consensus among medium-range deterministic and ML/AI guidance regarding the track and timing of any particular shortwave upper trough later next week, precluding the introduction of any severe probabilities this outlook. ..Squitieri.. 09/03/2026
