A watch is currently not expected. DISCUSSION...Ahead of a vigorous vorticity maximum centered over the Champlain Valley, visible satellite imagery indicates deepening cumulus across the discussion area amidst a warming and destabilizing air mass with around 500 J/kg of MLCAPE. Eventual thunderstorm development is expected later this afternoon as height falls/cooling aloft overspread the warming boundary layer, contributing to further air mass destabilization. The kinematic environment features strong mid/upper-level winds, resulting in long, straight hodographs supportive of splitting supercells with an associated hail risk. Isolated damaging wind gusts also appear possible owing to the steepening low-level lapse rates across the region, which will enhance evaporative cooling in the sub-cloud layer. ..Mead/Smith.. 08/24/2026 ...Please see www.spc.noaa.gov for graphic product...
