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 highly unlikely during the entire
period (e.g. less than a 30% probability for a regional severe
storm area across the CONUS through the entire Day 4-8 period). |
