Valid 092042Z - 092215Z The severe weather threat for Severe Thunderstorm Watch 665 continues. SUMMARY...A few damaging gusts may accompany the stronger storms over the next few hours. A brief tornado cannot be ruled out. DISCUSSION...Multicells, transient supercells, and short line segments have become established along/ahead of a surface trough. These storms are overspreading a boundary layer characterized by 80s/70s F surface temperatures/dewpoints, where 1000-1500 J/kg MLCAPE is in place, along with 30-40 kts of effective bulk shear. The current thinking is that these storms will maintain their intensity and continue to pose a risk for a few damaging gusts. A brief tornado also cannot be ruled out, especially for any storms that anchor on the baroclinic boundary, roughly established along the OH/PA/NY border area. ..Squitieri.. 09/09/2026 ...Please see www.spc.noaa.gov for graphic product...
