https://en.m.wikipedia.org/wiki/Thunderbird_(mythology)

The thunderbird is a legendary creature in certain North American indigenous peoples' history and culture. It is considered a supernatural being of power and strength. (power and strength)

The thunderbird is said to create thunder by flapping its wings (Algonquian[1]), and lightning by flashing its eyes (Algonquian, Iroquois[2]). (reads like a storm)

In Algonquian mythology, the thunderbird controls the upper world while the underworld is controlled by the underwater panther or Great Horned Serpent. The thunderbird creates not just thunder (with its wing-flapping), but lightning bolts, which it casts at the underworld creatures.[1] (sounds like an epic fight)

They were also used to punish humans who broke moral rules. The thunderbirds lived in the four directions and arrived with the other birds in the springtime. (and here we are, spring is around the corner)

Edit: u/7nick9 - if the end of that runway sign is a 6, and the thunderbird arrives in spring - then is it notable that the first day of spring is in 6 days?????
