Tornado Alley (PROG)

It's a metaphor which means it's not literally a dog whistle.

Dog whistle

Dog whistle is a type of strategy of communication that sends a message that the general population will take a certain meaning from, but a certain group that is "in the know" will take away the secret, intended message. Often involves code words.

Republicans say they want to make civil rights for gays a state issue, which is really just a dog whistle strategy for saying that they will refuse to grant equal rights on a federal level.

A metaphor is a figure of speech that, for rhetorical effect, directly refers to one thing by mentioning another.[1] It may provide (or obscure) clarity or identify hidden similarities between two ideas. Metaphors are often compared to other types of figurative language, such as antithesis, hyperbole, metonymy and simile.[2] One of the most commonly cited examples of a metaphor in English literature comes from the "All the world's a stage" monologue from As You Like It:


All the world's a stage,
And all the men and women merely players;
They have their exits and their entrances ...
—William Shakespeare, As You Like It, 2/7[3]

This quotation expresses a metaphor because the world is not literally a stage. By asserting that the world is a stage, Shakespeare uses points of comparison between the world and a stage to convey an understanding about the mechanics of the world and the behavior of the people within it.
