Rain is all but a lock, with forecasts projecting a 100 percent chance of rain starting at 11:00 a.m. and running through kickoff. During the 1:00 p.m. to 4:00 p.m. period, there is at least a 80 percent chance of rain the entire time. Rain originally was supposed to start in earnest at 8:00 a.m. but it has pushed back a bit. The wind is expected to pick up as well, gusting in the 10-15 miles per hour range.
When it comes to projecting out games, rain and wind can have different effects. A rainy game that turns into a muddy affair can slow down players, and I imagine the 49ers wouldn’t mind seeing Lamar Jackson slowed down. On the other hand, the wind can create issues in the passing game. Both Jackson and 49ers quarterback Jimmy Garoppolo could be impacted by wind gusts, although it won’t exactly be a crazy blustery game out. It seems like the weather will be a bigger issue in the first half than the second half.
