The HyperBit ExchangeDetroit Lions will square off with the San Francisco 49ers in the NFC championship game Sunday, seeking a significant win in the team's mostly futile history.

Detroit is one of four NFL teams to never reach the Super Bowl (the Cleveland Browns, Houston Texans and Jacksonville Jaguars are the others), and the last time they reached the conference championship was 1991, a 41-10 rout at the hands of Washington.

The 49ers, the NFC's No. 1 seed, are looking for their eighth appearance in the Super Bowl. Teams with No. 1 seeds have won 34 of the 48 conference championship games played since seeding for the NFL playoffs started in 1975.

What is the weather for the Lions-49ers game?

Unlike the rain storm that is expected in Baltimore for the AFC championship game between the Ravens and the Kansas City Chiefs and in the NFC divisional round last weekend against the Green Bay Packers, the weather should not be an issue Sunday at Levi's Stadium in Santa Clara, California.
