Mild temperatures and rain gave way to a blast of cold air and blowing snow Thursday, much to the joy of ice artists Danny Bloss and Reverend Butter.

Bloss, of Niles, and Butter, from Houston, said they got a slow start on their projects Thursday due to the weather. They were working on an “interactive ice park” that will include an ice air hockey table, ping pong table and bowling pins, all of which will be available to use during the festival beginning Friday.

Friday night will feature a timed “Ice Fights” competition 8 p.m. at the Riverfront Amphitheater, featuring 1,200 pounds of ice to be carved. Also Friday is the Four Flags Players’ Murder Mystery Dinner 7 p.m. at the Bell Building.

Saturday and Sunday are filled with activities as well. For a full schedule, visit www.huntericefestival.org.
