Note: A severe weather area depicted in the Day 4-8 period indicates 15%, 30% or higher probability for severe thunderstorms within 25 miles of any point.
PREDICTABILITY TOO LOW is used to indicate severe storms may be possible based on some model scenarios. However, the location or occurrence of severe storms are in doubt due to: 1) large differences in the deterministic model solutions, 2) large spread in the ensemble guidance, and/or 3) minimal run-to-run continuity.
POTENTIAL TOO LOW means the threat for a regional area of organized severe storms appears unlikely (i.e., less than 15%) for the forecast day.

   Day 4-8 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   0308 AM CDT Fri Oct 29 2021

   Valid 011200Z - 061200Z

   ...DISCUSSION...
   A progressive upper-air pattern will characterize the extended
   period and a low-potential highlight of severe weather for each day.
   Surface high pressure will generally be located over the central
   U.S. with little in the way of return flow into the northern Gulf
   Coast during the latter part of the period.
