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
   0343 AM CST Sun Jan 23 2022

   Valid 261200Z - 311200Z

   Medium-range guidance is in relatively good agreement that broadly
   cyclonic upper flow will cover much of the CONUS early D4/Wednesday.
   A series of shortwave troughs are forecast to progress through this
   upper troughing throughout the period, as upper ridging gradually
   builds eastward over the western CONUS. As a result, an amplified
   western CONUS ridge/eastern CONUS trough pattern is anticipated on
   D5/Thursday and D6/Friday.  

   Even with the development of this amplified character during the end
   of the week, the overall upper pattern is expected to remain
   relatively progressive with a less amplified pattern developing this

   Continual reinforcement of the dry and stable conditions will keep
   severe thunderstorm potential very low from D4/Wednesday through
