It’s about to get real: What you need to know about the Iowa caucuses

USA Today reports:

The caucuses begin at 7 p.m. Central time as voters gather at locations scattered around the state. But that is not the start of the voting. Caucuses generally begin with speeches in support of candidates before the actual voting gets underway.

There's more:

There is no "poll closing" time like a regular election; caucuses take as long as caucuses take. But the bulk of the results are likely to be reported to state party headquarters and then reported to the media sometime after 9 p.m. Central time.

Stay tuned.
