snowball's chance in hell

Noun

 * 1)  Little (if any) likelihood of occurrence or success.
 * That small boat has a snowball's chance in hell of surviving the hurricane.

Usage notes
Often, the expression is used in the negative for even more emphasis (implying that the referent has even less chance of success than a snowball in hell because the heat would melt it near-immediately).
 * That small boat doesn't have a snowball's chance in hell of surviving the hurricane.
