Day 4-8 Convective Outlook 
NWS Storm Prediction Center Norman OK
0300 AM CDT Wed Aug 31 2022

Valid 031200Z - 081200Z

...DISCUSSION...
Forecast guidance is in fairly good agreement that an weak upper
trough will persist over the Northeast for much of the Day 4-8
period. Meanwhile, an upper ridge will persist across much of the
western U.S. The upper ridge will extend northeastward into portions
of the northern Plains early next week, while a weak upper low
traverses the southern Plains around the same time. Deep-layer flow
will remain weak through period with little large-scale forcing for
ascent. As a result, severe potential appears low during the Day 4-8
period.
