Driest January?

Across much of Northern and Central California there has been little if any rain this month and monthly totals will wind up at or near long term records.  Below are the 15 lowest January totals for each station's period of record.

Looking at San Francisco, note that three of the five driest years are in the top five.  This has brought the average for the past ten years down to 3.03, dramatically lower than the 30-year normal of 4.55 inches.
