Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0325 AM CST Mon Dec 22 2025 Valid 251200Z - 301200Z ...DISCUSSION... An upper-air pattern featuring a ridge over the central states will quickly transition to a more progressive flow regime towards early this weekend. Model guidance implies a split-flow regime potentially evolving with troughing over the Great Lakes towards the Sunday-Monday timeframe (D7-D8). Overall limited potential for organized severe seemingly exists for much of the extended period. Some indication for a moist sector evolving ahead of the amplifying Great Lakes' trough could yield some severe risk, but predictability is low and highly uncertain given model spread at this point in time.
