Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0237 AM CST Mon Dec 01 2025 Valid 041200Z - 091200Z ...DISCUSSION... A series of progressive mid-level troughs, embedded in broader west-northwest to east-southeast flow aloft, will aid in reinforcing multiple rounds of surface high pressure across most of the CONUS, with static stability limiting thunderstorm development over most locales. There is the chance that ahead of some of the high pressure surges that some low-level moisture could advect inland from the Gulf. Should this occur, at least isolated to scattered thunderstorms will be possible. Compared to earlier medium-range guidance, some of the most recent guidance has diverged in agreement of a more robustly buoyant airmass advecting inland through this weekend into early next week. As such, it currently does not appear that an organized severe threat will materialize in the Days 4-8 period.
