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.

   0130 AM CST Sun Dec 03 2017

   Valid 061200Z - 111200Z

   ...DISCUSSION...
   The extended period will feature a persistent, amplified regime
   characterized by a deep trough in the eastern US and a ridge near
   the Pacific Coast. As a result, a continental air mass will be
   maintained east of the Rockies, precluding any notable return of
   boundary-layer moisture across the country. Therefore, the potential
   for severe weather appears low through next weekend.
