Day 4-8 Convective Outlook 
NWS Storm Prediction Center Norman OK
0313 AM CDT Sat Aug 20 2022

Valid 231200Z - 281200Z

...DISCUSSION...
The upper pattern D4/Tuesday morning is forecast to feature eastern
CONUS troughing and subtropical ridging over the central/southern
Plains and Southwest. The upper pattern is then forecast to
gradually transition towards more central CONUS troughing by the
weekend. Mid-level flow will be relatively modest throughout the
period across the entire CONUS. Buoyancy will be limited as well.
Thunderstorms are still possible, particularly with the moist air
mass over the Southeast and the monsoon conditions over much of the
Southwest and central Rockies. However, the lack of buoyancy and
shear should keep the threat for organized severe thunderstorms low.
