The evening of the 9th saw a powerful storm system and cold front move across northeastern Colorado. Temperatures plummeted and we saw our first snowfall of the season. Denver officially saw a 70 degree temperature change from the 9th to the 10th, tying the period for the second largest two-day temperature swing in Denver history.<\/p>\n
High pressure returned on the 12th and we warmed up and dried out again. Cool but non-dramatic conditions arrived for the 18th through the 23rd. We then saw our second snowfall on the 24th of the month.<\/p>\n
A brief rebound saw us warm up and enjoy a day of warmer than normal temperatures on the 26th. Once again, Mother Nature dropped the hammer with cold and snow returning on the 27th. The final five days of the month saw us receive two shots of snow and temperatures more akin to what we would expect to see in January.<\/p>\n
Overall, Thornton\u2019s average temperature for the month was 42.8 degrees. This was far below the long term Denver average for October of 50.9 degrees and was Thornton\u2019s second coldest October since ThorntonWeather.com came online in the fall of 2006.<\/p>\n
Out at Denver International Airport where the Mile High City\u2019s official measurements are taken, it was slightly warmer with an average of 43.7 degrees. That made the month the fourth coldest October in Denver weather history.<\/p>\n
Denver saw six cold weather daily temperature records fall. Among them were a record low of 13 degrees on the 10th, a record low on the 11th, record low maximums on the 28th and the 29th, and then two more record low temperatures on the 30th and 31st.<\/p>\n
