SF/NYG weather The local weather is a specialty of mine. What this information means, that's where your help is needed:
We're getting three storms after six weeks of almost no rain at all. The second one hits tonight. The third one hits around 5 p.m. Sunday, which should be halftime. This is also when the sun goes down.
The first half should be cloudy and breezy, and the field should be in good shape, because it won't have rained significantly for about 30 hours.
The second half will only be lit by stadium lighting, it will be windier (20 mph) and the rain will slowly increase over time. It will be heaviest at the end of the fourth quarter, although at that time it should only be a moderate rain. If the game goes into overtime, the rain could turn heavy. For what it's worth, I don't think the 49ers have played in the rain all year.
