...DISCUSSION...
A rather stagnant upper-air pattern will be in place across the
CONUS into early next week, with an upper ridge continuing over the
central U.S. as a mid-level cut-off low meanders along the Atlantic
coastline and an upper trough gradually amplifies along the West
Coast. By the middle to end of next week, the West Coast upper
trough will advance eastward toward the Rockies, encouraging surface
lee troughing and subsequent low-level moisture return (albeit
modest) across the Great Plains states. Thunderstorm development is
possible, especially across portions of the southern High Plains
Days 6-7 (next Wednesday-Thursday). However, deterministic guidance
suggests that little overlap of meaningful buoyancy and vertical
wind shear will take place over the southern High Plains next
Wednesday-Thursday, with calibrated ML/AI guidance only hinting at a
severe threat that will be isolated at best. Therefore, severe
probabilities have been withheld this outlook.
