Concerning...Severe Thunderstorm Watch 397... Valid 262016Z - 262215Z The severe weather threat for Severe Thunderstorm Watch 397 continues. SUMMARY...The threat for large hail up to 1.5" and locally severe wind gusts of 60-65 kt continues across the watch area. DISCUSSION...An earlier cluster of thunderstorms with embedded supercell structures that produced wind damage and some small hail in central Rutland County, VT has recently weakened. However, the lingering convection is in the vicinity of a diffuse warm front that extends southeast through southeastern NH. That boundary along with orographic ascent along favored terrain in the Green and White Mountains may aid in additional storm formation late this afternoon into early evening. Given the presence of 1000 J/kg MLCAPE and 35-45 kt of effective bulk shear, the environment is expected to remain supportive of additional severe storms capable of hail up to 1.5" and damaging wind gusts for the next few hours. ..Mead.. 06/26/2026 ...Please see www.spc.noaa.gov for graphic product...
