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...
Most recent medium-range guidance begins to diverge early in the
extended period with the active pattern across the central and
eastern CONUS likely contributing to the run-to-run and
model-to-model inconsistencies. Even with the various solutions
offered, none of the guidance suggests widespread severe
thunderstorms for any day in the extended period.
