Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0205 AM CST Wed Dec 03 2025 Valid 061200Z - 111200Z ...DISCUSSION... Multiple mid-level troughs will traverse the CONUS while translating within a broader west-northwest to east-southeasterly upper level flow regime through the Days 4-8 period. Periodic bouts of surface high pressure will reinforce a statically stable, cool and dry airmass across most of the CONUS, limiting thunderstorm development. One exception will be with the Gulf Coast states early next week, when a surface low preceding one of the embedded mid-level troughs will encourage onshore flow from the Gulf. Should this occur, enough buoyancy will be in place (along with deep-layer ascent) to support thunderstorms. However, buoyancy may be too weak to support a severe threat.
