February 2019 weather recap: Thornton experiences a very cold, somewhat snowy month

Friday, March 1st, 2019 3:41pm MDT

Cold and snow. Those were certainly the operative words for the month of February 19. Thornton recorded its coldest February in the past 12 years and its snowiest month overall since March 2016.

Mild temperatures started things off for the first four days of the month and fooled us into thinking of an early spring. Those dreams were soon crushed though as the first extended period of below normal temperatures arrived on the 6th. Six straight days of below normal temperatures then arrived as did our first shot of snow for the month.

We rebounded briefly for a four day period from the 12th to the 15th with mild temperatures. Once again though, the mercury plunged delivering 13 straight days of below normal temperatures and five days of measurable snowfall.

Thornton recorded an average temperature for the month of 26.3 degrees. This was our coldest February since ThorntonWeather.com came online in 2007 – by more than two degrees. Out at Denver International Airport where the Mile High City’s official readings are taken it was slightly warmer with an average of 28.0 degrees.  Both were well below Denver’s long term February average of 32.5 degrees for February.

While certainly cold, neither average reading for the month could crack Denver’s list of top 10 coldest Februarys.

Thornton saw its warmest mercury reading for the month of 62.3 degrees on the second. Its coldest reading of -7.7 degrees came on the 7th of the month. Denver saw a maximum of 65 degrees on the 3rd and its low of -11 degrees on the 7th.

February is usually a dry month with Denver averaging 0.37 inches of liquid precipitation. Thornton recorded 0.60 inches this year while Denver saw 0.72 inches.

Similarly, snow was a good bit above normal for February as well. Thornton saw 11.2 inches of the white stuff while out at the airport 13.4 inches was recorded.
