Note on Medium Range Outlooks

You are looking at an outlook that is part of the medium range forecast (the outlook for days 4-8). The most important thing to note is that lack of a risk does not mean zero risk. Generally speaking, confidence has to be pretty high for the Storm Prediction Center to have an outlook area this far into the future.

When no specific risk areas are shown, you might see one of these phrases:

DISCUSSION

Initially dry conditions will keep the severe weather threat low on D4/Tuesday. As a mid-level trough traverses the Rockies on Monday, lee troughing will strengthen on D5/Wednesday. This will bring substantial moisture return across the Plains. Given the early stage moisture return, more than an isolated severe weather threat appears unlikely on D5.

A more substantial severe weather threat is anticipated on Day 6/Thursday. The evolution of the mid-level trough still remains unclear, but an overall pattern featuring broad troughing across the southern/central Plains, moderate to strong instability, and a sharp dryline, could support at least isolated supercells Thursday afternoon/evening. Have added a 15% area from western/central Oklahoma into southern/eastern Kansas where the severe weather threat seems likely regardless of how exactly the mid-level pattern evolves.

The uncertainties discussed for Day 6 become greater on Day 7 and beyond. Persistent troughing across the Plains and considerable instability suggest that severe weather is likely on Friday (and likely into the weekend). However, the progression of the mid-level trough and the associated surface features need to become more clear before a 15% area can be defined for these days.
