Denver’s February weather is usually relatively uneventful although that isn’t always the case as we can see from our look back at this week in Denver weather history. From extreme cold to major snowstorms and damaging winds, this period has seen some historically significant events.
From the National Weather Service:
30-7
In 1985…a cold front on the 29th produced a protracted cold spell as arctic air remained entrenched across metro Denver. While the only daily temperature record set was a low maximum reading of 2 degrees on February 3rd…minimum temperatures plunged well below zero on 9 consecutive days. The coldest readings were 15 degrees below zero on January 31st and 14 degrees below zero on February 5th.
31-8
In 1963…warm weather that began with the strong Chinook winds on the 31st and 1st continued through the 8th. Maximum temperatures through the period ranged from 52 degrees on the 2nd to 76 degrees on the 5th…which was a new record high for that date.
31-12
In 1899…a protracted cold spell lasted almost two weeks. Low temperatures plunged below zero on all days but February 9th with a reading of 6 degrees. The coldest low temperature of 22 degrees below zero on February 6th was a record low for the date. Low temperatures of 20 degrees below zero occurred on both February 11th and 12th… But only the 11th remains as the record minimum for the date. High temperature of only 5 degrees below zero on February 11th was a record low maximum for the date. High temperatures climbed to only zero degrees on both February 2nd and 3rd…but were not records. Intermittent light snow or flurries fell during the period. The most snowfall…2.0 inches…occurred on February 2nd.
1-3
In 1996…cold arctic air plunged temperatures below zero for more than 35 consecutive hours from late on the 1st until sunrise on the 3rd. The temperature warmed to only 1 degree below zero on the 2nd after a record low of 16 degrees below zero.

In 2011…a frigid arctic airmass settled into Front Range urban corridor. At Denver International Airport… Overnight low temperatures…from the 1st to the 3rd… Were 13 below zero…17 below zero and zero respectively. The icy temperatures caused pipes to crack and burst following the freeze. In Loveland…firefighters responded to more than a dozen water pipe breaks…most in fire sprinkler systems at businesses…apartments and assisted care facilities. At cu earth science library in Boulder…more than 1000 books and several costumes for an upcoming production were damaged. At the County courts administration building in Jefferson County…a steady stream of water from a crack on the 5th floor… Went unnoticed on the 3rd and flooded all the floors of the administration wing overnight. As a result…much of the office equipment…furniture and carpet sustained water damage. A burst sprinkler line caused minor damage at the Platte Valley Medical Center in Brighton. The icy temperatures forced to closure of several school districts as well.

In 1985…the most bitter cold spell of the winter season brought sub-zero temperatures to metro Denver. Daily low temperature records were broken at Denver. The usual cold weather problems struck including stalled vehicles…jammed traffic lights…and frozen water and sewer lines. At Stapleton International Airport…the high temperature was only 2 degrees above zero on the 1st…setting a record low maximum for the date. Low temperatures reached 13 below zero on the 1st…12 below on the third…and 14 below on the 5th.

In 1989…one of the century’s worst doses of winter weather ravaged the entire state. Bitterly frigid weather moved into metro Denver on the 1st as snow buried many sections of the state. In metro Denver where 3 to 6 inches of snow fell…blowing snow and resultant poor visibilities caused a 46-car pile-up on I-25 in the middle of the city on the 4th. During the period…2 to 3 hour delays were common at Stapleton International Airport where snowfall from the storm totaled 4.3 inches and northeast winds gusted to 30 mph on the 1st. Intense cold accompanied the storm. Temperatures in Denver stayed below zero continuously for the best part of 3 days (3rd…4th…5th)…for a total of 69 hours. This is the fourth longest sub-zero period on record. Wind chill temperatures reached 50 degrees below zero. The mercury dipped to 24 degrees below zero on the 5th…setting a record for the date. This was the city’s coldest temperature in over 26 years. Low temperatures dipped below zero on 8 consecutive days (2nd-9th). High temperature of 9 degrees below zero on the 4th was a record low maximum for the date…as was the high of 5 degrees on the 5th. Extensive damage occurred when pipes and water lines froze and broke. Thousands of cars failed to start. On the 3rd…a 57-year-old woman died of hypothermia in an Arvada park. Eighteen high school students were treated for hypothermia after a 2-hour ride through Jefferson County in an unheated bus. At least 2 cases of frostbite were reported; there were undoubtedly many more.

As we wrap up a January that was pretty much average in terms of temperature and precipitation, we look to February with hope for relief from the dry conditions we have seen thus far this winter. Unfortunately historically February is a relatively dry month but we do start working off winter as temperatures climb.
