Weather gets treated as a single blanket downgrade for outdoor passing games. In practice, the type of weather changes which specific markets are affected and by how much.
Wind: the biggest real threat to passing volume
Sustained wind, especially above roughly 15-20 mph, is consistently the most disruptive weather factor for passing games — it affects deep-ball accuracy and field goal range more than short, high-percentage throws. Teams facing strong wind often lean harder on the run and short passing game, which suppresses passing-yardage and passing-touchdown props while sometimes boosting rushing attempts.
Cold weather: overrated for passing, underrated for ball security
Extreme cold alone has a smaller effect on passing efficiency than its reputation suggests — modern passing offenses function reasonably well in cold, dry conditions. Cold combined with wind or precipitation is where the compounding effect shows up.
Rain and snow: volume shifts more than accuracy collapses
Precipitation tends to reduce explosive-play rate and can increase fumbles on catches and handoffs, which matters more for touchdown-driven props than for raw yardage. Play-calling often shifts toward a more conservative, run-leaning approach specifically to protect the ball.

Dome and retractable-roof games
Games played indoors, or under a closed retractable roof, remove weather as a factor entirely — which is itself useful context when comparing a player's home performance to his road performance if his home stadium is a dome.
How this fits into the pipeline
Weather is one of several contextual factors alongside schedule, line movement and injury data that feed into nightly scoring before picks are frozen pre-kickoff. See how SharpSlap works for the full sequence from data collection to publication.
