NFL week 3: Rain to threaten games in Kansas City, Seattle

While most NFL fans will need sunglasses for Sunday's games, rain gear will be a must have for those in Seattle and Kansas City, Missouri.

Here is a breakdown of the forecast for both games:

Soaking rain and thunderstorms that reached Kansas City during Saturday night are expected to linger for part of Sunday as the undefeated Ravens and Chiefs square off at Arrowhead Stadium.

Fans should use caution when heading to the game as there can be ponding of water on some roads.

The heaviest rain is expected to occur during the morning hours for pregame tailgates before tapering off for the game itself.

Still, a leftover stray shower or thunderstorm cannot be ruled out for the game. Any lightning in the area could prompt a brief delay.

Temperatures will be in the lower 70s F throughout the game with similar AccuWeather RealFeel® Temperatures.

A breeze up to 14 mph from the west will generally be a crosswind at Arrowhead Stadium, and may impact higher passes and kicks.

It will be a rather dreary day in Seattle as a storm system moves into the area and brings periods of rain.

The rainfall will necessitate fans bringing along ponchos and waterproof gear, and it can make the field and ball slick for the players.

It will be cool with cloudy, rainy weather as temperatures are forecast to be in the lower to middle 60s during the game.

A south wind of 7-14 mph will blow toward the northern end zone.
