Mesoscale Discussion 1055 NWS Storm Prediction Center Norman OK 1232 PM CDT Sat May 31 2025 Areas affected...Parts of the central Appalachians and Piedmont Concerning...Severe potential...Watch unlikely Valid 311732Z - 311930Z Probability of Watch Issuance...5 percent SUMMARY...A couple strong to locally damaging gusts and small hail are possible through the afternoon. DISCUSSION...Widely scattered thunderstorms are evolving southeastward across parts of the central Appalachians -- focused within the left exit region of a robust midlevel jet streak. Limited boundary-layer moisture (upper 40s to lower 50s dewpoints) are yielding weak buoyancy, however, steep midlevel lapse rates and straight/elongated hodographs (40-50 kt of effective shear) could still support transient storm intensification/organization. Given 30-40-kt winds in the lowest 2 km AGL (per VWP data), convective momentum transport may favor a couple strong to locally damaging gusts through the afternoon, and small hail will also be possible. ..Weinman/Hart.. 05/31/2025 ...Please see www.spc.noaa.gov for graphic product...
