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.

   ...DISCUSSION...
   Through the upcoming week, a deep/amplified trough will organize
   across the eastern half of the US. At the surface, a cold front will
   push towards the Southeast on D4/Tuesday, with a cold, continental
   air mass building behind it. This air mass should generally remain
   in place east of the Rockies through the remainder of the week. In
   turn, stable conditions will minimize the potential for severe
   weather in the extended.
