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).
        
000 ACUS48 KWNS 190835 SWOD48 SPC AC 190833 Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0333 AM CDT Mon Aug 19 2019 Valid 221200Z - 271200Z ...DISCUSSION... On Thursday/D4, a vertically stacked low will develop over southern Quebec with strong southwest winds aloft overspreading the northeastern states. A cold front will rapidly move across New England and will trail southward toward the Delmarva, though models differ in timing. MUCAPE on the order of 1000 J/kg is expected over northern areas ahead of the front, with greater values approaching 2000 J/kg into NJ and eastern VA where dewpoints will be in the 70s F. Shear will be less over southern areas, but still sufficient to support at least a marginal wind and hail threat. Long hodographs will favor cells or fast-moving line segments over northern areas, but there is more model discrepancy regarding speed of the cold front. If the more progressive model solutions are correct, there may be little opportunity for severe storms north of Long Island. As such, will defer possible upgrades to later outlooks. To the west, a lesser shortwave trough will move across the northern Rockies and Plains during the Thursday/D4 to Friday/D5 period, though models vary greatly with the strength of this feature. Regardless, southeast surface winds may result in enough moisture advection into the northern Plains for at least a marginal severe risk along an attendant cold front. For the Saturday/D6 to Monday/D8 period, a relatively strong upper jet is forecast to nose into the northern Rockies and Plains, then eventually into the upper MS Valley. Increasing shear and lift will likely interact with increasing low-level moisture and instability over the Dakotas, MN, NE and IA. Predictability is low for this time frame, but probabilities could be added in future outlooks. ..Jewell.. 08/19/2019
