It has been an incredibly foggy autumn here in Davis (and throughout much of the CA Central Valley).  I made a histogram of daily rainfall totals from the past 50 days of my Cocorahs gauge.  I’ve grouped totals into 0″ (clear, cloudy, or light fog), 0.01″-0.02″ (heavy fog), and >=0.03″ (rain).  So far this autumn, over half of our days have seen measurable precipitation but 60% of those days have been from fog-fall rather from rainfall.
