Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1118 PM CST Wed Nov 20 2024 Valid 211200Z - 221200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... A few thunderstorms are possible across southern New England Thursday morning. ...Southern New England... Strong upper low will shift southeast from the Great Lakes into the upper Ohio Valley by late afternoon. This evolution will encourage low-level warm advection across southern New England as a surface low repositions itself off the middle Atlantic coast, south of Long Island. Forecast soundings suggest weak elevated buoyancy will develop north of this boundary as mid-level lapse rates will steepen as 500mb temperatures cool in advance of the approaching trough. Strongest elevated updrafts may exceed levels necessary for lightning discharge, but this should mainly be prior to 18z. Thereafter, deepest convection will focus offshore. ..Darrow/Wendt.. 11/21/2024
