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 means severe storms are possible. However, no severe weather areas are included as the severe threat is less than 30% due to expected limited coverage or uncertainty on the timing and location of such an event.
POTENTIAL TOO LOW is used when the threat for organized areas of severe storms appears highly unlikely during the entire period.

   ...DISCUSSION...
   
   MEDIUM RANGE MODELS CONTINUE TO SUGGEST THAT LARGE SCALE PATTERN
   WILL REMAIN TOO CHAOTIC AND GENERALLY A BIT TOO WEAK REGARDING
   SHEAR/INSTABILITY FOR ORGANIZED SEVERE THUNDERSTORMS.  ALTHOUGH
   THUNDERSTORMS WILL LIKELY DEVELOP ACROSS A GOOD PORTION OF THE
   COUNTRY...AT LEAST ON AN ISOLATED BASIS...SEVERE PREDICTABILITY IS
   TOO LOW TO WARRANT AN OUTLOOK.
