We've had two decent storms this Fall so far and I've missed both of them due to travel. I know from my airline pilot's report last night that it rained pretty hard last night and I heard that put a damper on the Holiday Parade. Here is last year's post on the tree lighting. The National Weather Service gives us the specifics:
December 6th SFO Airport received 0.29 inches of rain which is about half of our normal accumulation for November. Since July 1st we have received 1.43 inches which is about one-third of normal. For the year we are at 20% of normal. You can see the details here.
I hope we don't have another dry year.
