No, the lightning trophy belongs to Florida, where its cities average about 90 thunderstorms a year -- or one every fourth day. They have a unique situation from being a peninsula. The inland areas will radiate their heat upward.
Cool sea breezes will rush in to replace the air, but they get a sea breeze from both their western and eastern shores. Those sea breezes collide over the inland areas and create convection, which leads to thunderstorms.
