Does It Actually Work?
the validationReading the Index
Negligible
Dome, retractable roof closed, or calm & mild. Weather is a non-factor.
Minor
Breezy or cool. Slight edge to the run game; kickers unaffected.
Notable
Real wind, rain, cold or heat. Deep passing and long field goals at risk.
High
Conditions that historically depress scoring and flip game scripts.
Extreme
Blizzard, gale, downpour or dangerous heat. Total game-changer.

Warm teams in the cold ❄️
