Another factor to consider is the 20-30% chance of thunderstorms during the game.
Storms will be widely scattered, but any sudden downpours could make the field and the ball slippery, slowing down the pace of the game and increasing the likelihood of turnovers.
Historically, heavy rain has decreased total points scored in NFL games by 6 points, while also reducing the point spread by 1.5 points.
Lighter rain decreases scoring by 2 points and the point spread by 0.5 points.
