An immate is suppose too get out the 28 and that is his maxout date but he didn't go to court because of snow so does this mean the other county will pick him up on his release date and not get out?

If they are scheduled for release on the 28th, what is the court date about? If another county is picking him up, then he has a "detainer" on him. That is when another jurisdiction requests a hold on that person so they can bring them before the judge in their county that issued the warrant.
