With about 45 days left in the calendar year, Reno has broken a record for precipitation.
This does include snowfall too. When it snows we calculate the liquid-equivalent so we can keep track of the total precipitation, both rain and snow. For instance, ten inches of snow generally melts down to about one inch of liquid precipitation equivalent.
Weather data for the Reno area goes back to the late 1800’s, though rainfall records for the calendar year are a little sparse during that time. The yearly rainfall records get a lot more detailed in the early 1900’s.
The previous wettest calendar year was 1983 when 13.2 inches of precipitation fell. An average year for Reno yields between 7 and 8 inches.
Much of this precipitation fell early in 2017 via ‘atmospheric rivers’ of moisture. California had record-setting rainfall in the winter of ’16-17 as moisture kept coming onshore. The latest pattern, which we wrote about a few days ago, bumped Reno into the top spot for precipitation record.
What about the rest of this winter? It appears northern California and the northern U.S. will continue to be wetter and cooler than average.
