Our recent blast of Arctic air sent the mercury tumbling and in the process broke two daily records for December 30th.
The official “high” temperature in Denver, as measured at DIA, reached only 1 degree at 1:23pm. This easily bested the record low high for the date of 8 degrees set in 1915. Thornton was slightly warmer than the airport with a high temperature of 2.4 degrees.
Additionally, at 9:23pm, the mercury plummeted to -19 degrees at DIA. This crushes the old record low temperature for December 30 of -11 degrees set in 1898. Here in Thornton we did not get quite as cold with a low temperature reading of -12.1 degrees occurring at 10:50pm.
