SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0720 AM CDT Fri Oct 31 2025 Valid 311300Z - 011200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm potential is low today and tonight. ...Discussion... Highlighted by an amplifying longwave trough east of the Rockies and the prevalence of continental trajectories, the large-scale pattern will generally not be conducive for convection capable of generating lightning today. A couple of lightning flashes could occur early today across northern New England with focused ascent near the surface low/northward-shifting front, but this potential will remain limited and diminish over time. Weak elevated convection may develop late tonight across west-central Texas in vicinity of the Low Rolling Plains as warm advection increases, but forecast thermodynamic profiles suggest that charge separation is unlikely prior to 12z Saturday. ..Guyer/Kerr.. 10/31/2025
