The Week 17 NFL weather forecast looks like it will be a rainy one, but before we get in to the individual games that could be impacted by weather, I want to briefly discuss the difference between a rain forecast and a wind forecast and how you should manage your expectations (and your fantasy football team) for both.When I make a wind forecast a few days before the event, I feel very confident that the forecast will verify. This is because wind impacts an area relatively uniformly. That is, the stadium will see the same general wind as the rest of the city. Because winds are such a reliable weather variable, I think it’s actionable to see a high wind game a few days out and tinker lineups accordingly (i.e. sit QBs/WRs/Ks in high wind games). Saints @ Panthers | Jets @ Bills | Eagles @ Giants | Steelers @ Ravens. This is where the opening paragraph really comes in to play. All four of these games have a good chance of rain, but the honest truth is that I won’t know the extent of the rain until Sunday morning when I can pull up radar and analyze each situation. My current feeling would be to not make any roster moves on these games yet, but make sure you check back on Twitter for the latest updates on Sunday morning. If it just looks like passing showers, play ball! But if it looks like one or more of these games may be a true downpour, then consider making pivots.WEEK 17 DFS:DK Cash | DK GPP | Y!

The issue isn’t so much being 100-percent wrong (though that can happen); it’s that rain is not at all a uniformly distributed weather variable. You can see a game that plays dry while it pours for three hours right across the street, or you could a dry game that had an 80-percent chance of rain It’s very hard to pinpoint rain at a specific location and time until it’s nearly happening. For that reason I recommend always waiting until Sunday morning to make lineup decisions based on rain (I post updates on Twitter @KevinRothWx). The “looks like a rain game” on Friday can very easily become “The rain will be after the game” by Sunday. Before we break down the Week 17 forecast, here’s a reminder that if you have any questions about sports weather or how weather could impact play (and, potentially, your fantasy, DFS, and gambling decisions), don’t hesitate to reach out on Twitter @KevinRothWx or check our hourly NFL weather forecasts on RotoGrinders.

This is the one game that I feel most confident in seeing rain — high rain coverage and some impressive rain intensity at times (more than just a passing light shower). I think it’s fair to consider leaning a little more toward a run-heavy game script here, so I’d give a bump up to running backs and defenses.
