So I leave work around 7:15 this evening, and it has clearly rained very recently, and fairly hard. There's some lightning off to the east, but it's not raining at the moment. I head to my car, hop on 280 South heading for my home in Daly City. Just past the interchange with 101, traffic grinds to a halt. That happens during rush hour, but not this bad and not this late. It's stop and go traffic the whole way with no evidence of a wreck or lane closure. After about 20 minutes, I get up to the Ocean Avenue exit, and what do I see? Snow. Slushy snow, but a fair amount of it, and a lot of water. The ground was above freezing and the cars driving by were quickly melting the snow, but there was still a good amount between car tracks. I get up to the Mission Street exit and the snow is gone...just wet. Wow...it's very rare for snow to fall in the city of San Francisco. And when it does, it's at the top of Twin Peaks...that happens every few years. I've been out here six years, and all I'd ever seen was a couple of flurries out at Ocean Beach that never made it to the ground.
