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...
   A prominent upper ridge is forecast to encompass much of the central
   CONUS into the Southeast through the extended forecast period. The
   potential for organized severe thunderstorms each day should be tied
   to low-amplitude shortwave troughs moving around the upper ridge
   from the northern Rockies/Plains into the Midwest and OH Valley
   vicinity. If any of these small-scale perturbations cresting the
   ridge can encourage a convective cluster to grow upscale into an
   MCS, then damaging winds would be possible as convection spreads
   east-southeastward across parts of the Midwest into the OH Valley
   and Great Lakes. The northern extent of any appreciable severe
   threat will be tied to the presence of rich low-level moisture
   along/south of a weak front. At this point, predictability remains
   low regarding the evolution/timing of these subtle mid-level
   perturbations, and related potential for one or more bowing clusters
   to develop and pose an organized severe risk.
