Multiple winter storms brought rain and high-elevation snow to the West Coast in December, a welcome change in weather pattern that the region started to see in November and continued through the end of the year.
More Rain for the West Coast!
As reported by my AcuRite Atlas™ home weather station, the December rainfall total was 1.42 inches, double the November rainfall total. However, when compared to the weather data from the nearest National Weather Service location, the normal rainfall total for December is 2.68 inches. While this did feel like a rainy month, unfortunately it is well below the region’s normal December precipitation total, which are based on 30-year averaged data – called “Normal Value” in the official NWS chart below.

Cooling Trend Continues for Northern California
The temperature trend reported by my Atlas shows a general cooling trend continued from November and through the end of the year. But what is interesting to point out from the official NWS data, the average maximum and mean temperatures were still 5 and 2 degrees Fahrenheit
above normal, respectively. Additionally, the December 2020 temperatures were higher than last year. It is neat to see how your data reported in My AcuRite™ helps you identify local trends and extremes in your area and analyze how it compares to historical weather data observed by official NWS weather stations!
Short Days, Long Nights
I just want to quickly note that the light measurements on the Atlas are always interesting to watch this time of year. From the chart below, you can see how the measured light and light intensity are affected by cloud cover, and that the general trend dipped slightly around the Winter Solstice on December 21 and recovered to 9 hours and 30 minutes of daylight by the end of the year.
