SPC AC 211725 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1125 AM CST Sat Feb 21 2026 Valid 221200Z - 231200Z
Across the Carolinas, mid Atlantic and southern New England coasts, intense surface cyclogenesis will support very strong low-level warm advection. The strong ascent may result in enough elevated instability (100-200 J/kg) and intense precipitation rates to support a few lightning strikes within the warm conveyor belt of the Nor'easter as the low lifts northward along the coast Sunday night into early Monday.
