These features represent forecast thunderstorms and lightning. Thunderstorm and Lightning values range from zero (0) to 4 where 0 = None/Limited; 1 = Isolated or Slight Chance; 2 = Scattered or Chance T; 3 = Likely, and 4 = Dry Thunderstorms. For display purposes, values above zero are reclassified to 1.
