Note: A severe weather area depicted in the Day 4-8 period indicates a 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 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).

   VALID 101200Z - 151200Z

   ...DISCUSSION...
   SEVERAL FAST MOVING SHORT-WAVE TROUGHS WILL PROGRESS SEWD ACROSS THE
   GREAT BASIN TOWARD THE LOWER MS VALLEY EARLY NEXT WEEK.  ONE FEATURE
   IN PARTICULAR IS EXPECTED TO INDUCE MORE FAVORABLE TRAJECTORIES FOR
   MOISTURE TO ADVANCE INTO SRN LA/MS MONDAY BEFORE IT IS SHUNTED INTO
   THE NRN GULF BASIN.  WEAK BUOYANCY MAY DEVELOP AND SPREAD INLAND
   AHEAD OF POLAR FRONT BUT THE PROSPECT FOR ROBUST CONVECTION CAPABLE
   OF PRODUCING ORGANIZED SEVERE THUNDERSTORMS WILL REMAIN LOW THROUGH
   THE PERIOD.
