Second tier storm spells provide the double weather effect. This does not stack with current weather.
Thundery weather has a chance (33% to 50%) to give lightning spells a 25% power boost and a corresponding penalty to water spells. If Rairin Obi or Hachirin-no-Obi is equipped, the weather bonus will always be applied.
Ionohelix will always gain the full effect of this weather.
