NFL Week 18 Weather Report and Forecast - Showers in SEA

geno-smith-800x480

As usual in my NFL weather forecasts, the main focus is to identify games with high winds or heavy rain. Of all possible weather variables, wind is the biggest detriment to offenses, with a 15+mph wind being impactful and anything over 20mph sustained becoming a major problem for passing and kicking. Rain is another important factor in scoring, in particular heavy rain, which makes it harder to both throw and catch a pass, as well as turnovers increasing across the board. Temperature rarely impacts scoring, so it will only be noted here in extreme cases, like late-season games with temps below freezing. You can use this to your advantage making your picks on DFS sites and sportsbooks.

It’s also worth noting that while winds are fairly predictable a few days out, trying to pinpoint rain over a stadium is difficult even a few hours ahead of a game.

NFL Week 18 Weather Report & Forecast

Sunday Main Slate – January 8th

Arizona Cardinals at San Francisco 49ers – 10mph sustained wind with a chance for a stray shower. Looks mostly dry and unimpactful.

Los Angeles Rams at Seattle Seahawks – Best chance for rain of the week, and while I expect we’ll see some rain, I don’t think we’ll see anything too heavy or long-lasting, and only expect minor impacts.

Overall Week 18 Weather Forecast

When looking for an edge, I’m always trying to find high winds first, and rain/snow second. It looks like we’ll avoid any wind issues this week, and just have a few games with a chance for a rain (Seattle game being the most likely). As I mentioned earlier, it’s best to follow forecasts right up until kickoff, so stay tuned to @KevinRothWx for the latest.
