For the second month in a row, Mother Nature kept us cold and delivered a healthy dose of snow. Thornton experienced its second coldest November of the past 13 years and the snowiest of the past 13 years.
The month started out chilly but soon saw things stabilize and turn seasonal. Then, the 8th and 9th offered up our two warmest days of the month with readings of 71 and 79 degrees respectively. We quickly chilled out and saw our first snowfall of the month on the 9th although it was minimal.
From the 12th to the 19th, weather was relatively calm and temperatures for the most part warmer than normal.
After that, things went downhill with most of the balance of the month seeing temperatures well below normal. Light snow on the 20th, 21st and 22nd was followed by our most significant storm of the season on the 26th.
Thornton saw an overall overage temperature for November of 35.6 degrees. This was a good ways below the long term Denver average for the month of 38.3 degrees. Out at Denver International Airport where Denver’s official measurements are taken, the average temperature for the month was 36.2 degrees.
Temperatures in Thornton ranged from a high of 79 degrees on the 9th down to a low of 2 degrees on the 27th. Out at the airport, Denver saw its warmest reading of 77 degrees on the 9th also and its coldest temperature of -2 degrees on the 27th. The high temperature on the 9th was a record high for the date.
A generous amount of precipitation was received with Thornton recording 1.46 inches of rain and snowmelt. Denver lagged a bit with 1.31 inches. Both readings were well above the long term Denver average of 0.61 inches for November.
In terms of snowfall, the Mile High City averages 8.7 inches in November. Thornton’s reading of 16.7 inches and Denver’s of 13.7 inches easily bested the average.
