Is the conclusion a surprise, or does the story offer the reader hints of some manner of impending doom?

On reading "The Lottery," the reader might be struck by the story's violent conclusion in which Tessie Hutchinson is stoned to death. However, looking deeper, it is possible to find hints of this ending earlier in the story.
In the second paragraph, for example, when Jackson is describing the children, she talks about how they are gathering stones. Some children also stuff stones into their pockets.
In addition, in the next paragraph, Jackson describes the coming together of each family. This foreshadows the drawing of the lottery itself.
By highlighting these details, Jackson subtly drops hints to the reader that this lottery is no ordinary lottery. The reference to the gathering of the stones, in particular, foreshadows the story's violent ending. The reader, however, must be able to decode these subtle clues in order to predict the conclusion.
