Severe...probably once a year honestly. There is at least one game a year where the winds make passing really difficult to the point you have to only throw downfield with the wind and FG kicking is impacted forcing teams to go for it because they can't kick into the wind. It might not meet the level of severe in terms of the Patriot game last year, but in terms of its impacts on the game, it's at least once a year, which I think qualifies as severe in terms of a football game.
