NFL Nation: Weather
The latest from weather.com projects a 50 percent chance of rain with winds out of the southeast at 14 mph when the San Francisco 49ers and New York Giants kick off at 3:30 p.m. local time.
NFL rules require teams to cover natural grass fields if rain is expected during the week preceding each game.
Earlier: Which team benefits more from rain Sunday?
Weather forecasts are calling for a 70 percent chance of rain Sunday afternoon, a factor for the 4 p.m. ET kickoff featuring the Arizona Cardinals and San Francisco 49ers.
The forecast calls for only light winds, however, a plus for both teams' quarterbacks and kickers. The temperature in San Francisco is presently 50 degrees. The forecast calls for a high of 52.
The forecast is calling for temperatures in the low 60s with winds under 10 mph and no chance of rain. Field conditions at Candlestick Park can be slippery even without rain, particularly around the perimeter.
Elsewhere in the NFC West, the forecast calls for temperatures in the low 50s with a 30 percent chance of rain in Seattle. The St. Louis Rams could encounter tougher conditions in Cleveland, where the forecast calls for 25 mph winds and a 20 percent chance of rain. In Philadelphia, meanwhile, the Arizona Cardinals are expected to encounter temperatures in the low 60s with relatively light winds and no rain.
Four outdoor games in November could certainly offer worse conditions. Weather shouldn't be a huge factor for most of the division unless the Rams find themselves needing a field goal to win amid those strong winds in Cleveland. They could always go for it.
The Northwest weather was spectacular Saturday.
The second link features an image pulled Sunday morning from a webcam atop the Space Needle. The Sunday forecast calls for a 100 percent chance of precipitation when the San Diego Chargers and Seattle Seahawks kick off at Qwest Field.
It's going to be a wet one.
Temperatures should remain mild -- the expected high is 68 -- and only light winds are expected.
Wet footballs can facilitate turnovers, however.
The forecast calls for clear skies through kickoff.
That should help both quarterbacks.
