The first round of NFL playoff action with the Houston Texans defending against the Cincinnati Bengals. The game will take place at 4:30 p.m. EST (3:30 p.m. local time) at Houston's Reliant Stadium today.
Reliant Stadium is protected from the weather by its mostly glass roof, but tailgaters can look forward to warm temperatures.
"A cold front will be coming through there at night, but it will be warmer ahead of that," said AccuWeather.com Senior Expert Meteorologist Dan Kottlowski. "Temperatures around game time should be in the mid-70s with just an outside chance of a shower. They probably won't see much precipitation in Houston and certainly not anything significant."
Kottlowski also said to expect variably cloudy skies with partial sunshine and west winds of about 8 mph around kickoff. Watch live coverage on NBC beginning at 4 p.m. EST.
Saturday night, playoff action moves to The Big Easy where the Detroit Lions will take on the New Orleans Saints at the Mercedes-Benz Superdome in New Orleans at 8 p.m. EST.
Like Houston's Reliant Stadium, the Superdome has a roof to protect fans and players from possible inclement weather conditions.
"That could help keep people dry Saturday night," said AccuWeather.com Meteorologist Meghan Evans. "They'll see temperatures in the mid-60s with partly cloudy skies, but a shower could move in before kickoff. Things should dry out during the game, though."
