What happened: Hot conditions are part of the pregame backdrop for Kansas City. The Chiefs are still at 0-0 with the game not yet underway.

Why it matters: Weather is one of the few concrete variables before any on-field developments take over. With the score still 0-0, conditions remain part of the setup rather than the result.

What to watch: Watch for kickoff and whether the heat remains part of the game-day conversation once play begins.
