The Almanac's Take

Forecasts aren't posted yet for any game on this slate, so there's nothing to work with on temperatures, wind, or lines. What we do know: SF-LAC, DAL-LA, DEN-LV, and DET-MIN are all indoors, so a quarter of the slate is weather-neutral by design. The outdoor games worth watching as conditions develop are CHI-BUF at Highmark, MIA-GB at Lambeau, and BAL-PIT at Acrisure — mid-to-late December venues where cold and wind tend to show up. Check back once forecasts and lines populate; that's when this grid earns its keep.

Methodology

Conditions and venue come from the nflverse schedules feed. Temperature and wind are shown only when forecast — they are blank (never zero) for dome/closed-roof games and for outdoor games whose forecast hasn't posted yet. The spread is shown in favorite form; a positive home line in the source feed means the home team is favored. Lines are the market's, for context — not a betting recommendation.
