St. Paul’s big St. Patrick’s Day will take a slightly different route Saturday and it will be warmer than usual, but Mayor Chris Coleman once again will lead his green-clad clan through downtown.

Light rail construction means the noon parade will move a block north and run along Fifth Street, from Wall Street to Rice Park.

“There are few things more authentically St. Paul than the St. Patrick’s Day parade,” Coleman said this week.

This is billed as the city’s 46th annual parade by the organizers, the St. Patrick’s Association.

It’s going to be a particularly busy Saturday in downtown St. Paul, with a Wild hockey game at 1 p.m. and the WCHA’s Final Five tournament championship game at 7 p.m., both at the Xcel Energy Center.

In Minneapolis, the evening St. Patrick’s Day parade starts at 6:30 p.m. on the Nicollet Mall at 13th Street and goes up the mall to Fifth Street.
