Day 4-8 Convective Outlook 
NWS Storm Prediction Center Norman OK
0154 AM CDT Mon Aug 29 2022

Valid 011200Z - 061200Z

...DISCUSSION...
An upper ridge will persist over the western U.S. for much of the
Day 4-8 period. East of the Rockies, an upper trough over New
England will quickly lift northeast and move offshore on Day 4/Thu.
Beyond Day 4, mid/upper flow will remain very weak and somewhat
nondescript over the eastern two-thirds of the CONUS through at last
Day 6/Sat. By the later part of the period into Day 7-8/Sun-Mon,
forecast guidance varies considerably and predictability is low.
However, overall severe potential appears limited during the Day 4-8
period given the large-scale pattern with a lack of ascent to focus
any thunderstorm activity and persistent weak vertical shear.
