In the diagram below you can see what will happen through a series of freeze and thaw cycles (courtesy of Garteway Farms).

Frost heave shown due to improper use of concrete in and around post!

Not only is lateral pressure applied to the post and its concrete base, but the vertical ground expansion under the lid of concrete amplifies the upward motion of the post. As the concrete moves upwards, its rough edges dislodge surrounding dirt, which falls to the bottom of the hole.

Over time, the fence post is literally lifted right out of the ground! Decks and porches will be ruined, bridges and roads crack and deteriorate... and home repairs skyrocket. Cold and freezing weather wreaks havoc on post, pillars, sonotubes, decks, bridges and other structures with support columns. When repair work is needed, Powerblanket Keyhole Thawing Blankets will get the job done quickly. Thaw frozen ground in and around post and pillars quickly with these outdoor heated constructions blankets designed specifically for post hole repair.

If opportunity allows, a better technique for initial groundwork preparation is to dig a bell-shaped hole - larger at the bottom than the top. Also, the concrete should not extend above ground level. Doing this ensures that lateral expansion tends to force the post downwards, and also ensures that there is no lip for the expanding ground to get a hold of to lift the post upwards.
