February 5 to February 11 - This Week in Denver Weather History

February is generally a relatively calm weather month however just like any other month in Denver, it can and does see its extremes. In looking back at the Denver weather history calendar for the week, there are many entries for damaging wind, some heavy snowfall and extreme cold.

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.

1-5

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.

1-6

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.

1-9

In 1883…a protracted cold period occurred when low temperatures dipped below zero for 9 consecutive days. Low temperatures ranged from 22 degrees below zero on the 4th to 2 degrees below zero on the 1st and 6th. High temperatures ranged from 10 below zero on the 3rd to 23 on the 9th. Several temperature records were set that still stand today. Record lows of 18 below and 22 below zero occurred on the 3rd and 4th. Record low maximum readings of 2 below and 10 below zero occurred on the 2nd and 3rd. The high of only 10 below zero on the 3rd is the coldest maximum temperature ever recorded in Denver.

3-5

In 1982…a cold surge of arctic air brought light snow and sub-zero temperatures to metro Denver. Temperatures plunged to 6 below zero at midnight on the 3rd and never warmed above zero on the 4th as snow flurries continued. High temperature on the 4th of 1 below zero was a record low maximum. The temperature dipped to a record low of 15 below zero on the 5th.

4-5

In 1932…wind gusts estimated at 70 mph occurred in Boulder. A 60 mph wind gust was recorded to the east of Boulder in Valmont. Damage was minor.

Interactive map of snowfall totals across northeastern Colorado, February 2-4, 2012

Thornton residents have begun digging out from the major winter storm that deposited an extraordinary amount of snow on the city.  In the end, the storm will go into the record books as the biggest February snowstorm in Denver history.

Here is Thornton we recorded 13.8″ of snowfall and that was actually one of the lower totals across northeastern Colorado. It was however our biggest snowstorm since October 2009.

As officially recorded at Denver International Airport, Denver recorded 15.9 inches of snow from the storm system.  This handily broke the old single storm February record of 14.1 inches set in 1912.

Further, February 2012 now enters the history books as the 10th snowiest February ever recorded in Denver. With more than three weeks to go, it is possible we will climb the top 10 list even further.

The 12.5″ DIA saw yesterday set a new single day record for February 3rd beating the old record for the date of 9.5″ set in 1932. This also is the biggest single day snowfall total ever recorded in Denver during February.

Time lapse video of Thornton’s February 2012 snowstorm

The snow has moved out and the sun will be shining soon as residents begin digging out from a record-setting snowstorm.  Here is Thornton we recorded 13.8″ of snowfall and that was actually one of the lower totals across northeastern Colorado. It was however Thornton’s biggest snowstorm since October 2009 when we recorded 14.1″ from a late month event.

Snow began falling Thursday evening and continued through the night, all through the day Friday and into Saturday morning.  By this morning most of the metro area was only seeing a few flakes falling and by the end of the day the sun will return.

Below is a time lapse video from our east facing webcam.  It covers from 4:00pm on Thursday, February 2 to 6:00am on Saturday, February 4 compressing that period into a little more than one minute.
