Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0339 AM CDT Sat Oct 04 2025 Valid 071200Z - 121200Z ...DISCUSSION... A cold front will move offshore the Northeast coast and develop southward in the Mid-South/TN Valley area early the forecast period (around days 4-5/Tue-Wed). Severe thunderstorm potential is expected to be low as the front progresses given limited destabilization across the warm sector. The second half of the forecast period (days 6-8/Thu-Sat) becomes more uncertain as spread among forecast guidance increases considerably. Most guidance shows upper ridging building over the Plains through much of the period. Toward the weekend, an upper trough may develop southeast across the eastern half of the CONUS, but details regarding timing and spatial evolution of this feature vary considerably, resulting in low forecast confidence.
