    September usually brings good weather for football and that’s what we’ll see for most of Week 3’s games. However, there is a low chance of showers and thunderstorms at two games (Indy at Tennessee; Dallas at Chicago) while light rain is possible in Seattle.

    This weekly SportsEthos NFL weather report shows the weather forecast for each outdoor game. We will look for weather conditions that may help – or hinder – your fantasy players. We’ll also highlight games where weather forecasts may help us with Over/Under betting decisions.

    The forecasts for each game are immediately below. If you’re interested in how various types of weather impact scoring of skill position players, check out the list at the bottom of this article.

    NOTE: This report does not include games that are played in domes or retractable roof stadiums that are expected to have a closed roof.
