Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0400 AM CST Fri Dec 19 2025 Valid 221200Z - 271200Z ...DISCUSSION... The large-scale mid-level flow pattern during the upcoming week will feature ridging/anomalously high 500-mb heights over much of the central U.S., and southwesterly flow with embedded disturbances across the western states. Although low-level moisture will expand north/northeast from the southern Plains and Southeast into the Midwest/OH Valley region during the week, instability will remain generally limited due to warm mid-level temperatures. Overall, the potential for organized severe storms is expected to remain low each day.
