The end of January and the first week of February have historically been an active period in Denver weather.  We see many high wind events which are common this time of year as well as the usual snowstorms.  Given the extreme cold we are set to experience this week, one event 22 years ago serves as a timely reminder of the dangers of cold.  In 1989 one Arctic cold event turned deadly and dangerous.

26-1

In 1888…a protracted warm spell lasted a week.  Maximum temperatures ranged from 62 degrees on the 29th to an all time record high for the month of 76 degrees on the 27th.  Daily record high temperatures of 76…69…and 71 occurred on the 27th…28th…and 30th respectively. Record high minimum temperatures of 47 and 34 occurred on the 26th and 27th.

27-31

In 1951…a major storm dumped 10.1 inches of snowfall at Stapleton Airport.  Most of the snow…8.3 inches…fell on the 29th.  Cold arctic air accompanied the snow.  Several temperature records were set…including record low maximum temperatures of 4 on the 28th and 4 below zero on the 29th and record low temperatures of 12 below zero on the 29th and 24 below zero on the 31st.  Temperatures were below zero for 45 consecutive hours.

28-30

In 1887…winds were strong and gusty for three days in the city.  West and northwest winds were sustained to 56 mph on both the 28th and 29th and to 44 mph on the 30th. Temperatures warmed to a high of 57 degrees on the 29th.

29-30

In 1985…an arctic air mass with snow closed I-70 for a time in Denver and east of Denver.  Snowfall totaled 5.4 inches at Stapleton International Airport where north winds gusted to 29 mph on the 29th.

When Denver’s weather turns severe it can turn deadly and damaging.  As we look back at this week in Denver weather history we see a time when extreme cold claimed a life and many occasions where wind wreaked havoc and caused damage.

15-23

In 1962…a protracted cold spell kept metro Denver in the deep freeze for more than a week.  From the 15th thru the 23rd…low temperatures were zero or below for 9 consecutive days…but a daily record low was set only on the 22nd when the temperature dipped to 14 degrees below zero.  A record low maximum for the date was also set on the 22nd when the temperature climbed to only 11 degrees.  The coldest high temperature was 3 degrees above zero on the 21st…which did not break the record.  The protracted cold was broken for only a few hours on the afternoon of the 20th when Chinook winds warmed the temperature to a high of 38 degrees before another surge of cold arctic air plunged temperatures back into the deep freeze that evening.  The severe cold caused much damage to water systems.  A woman was frozen to death at Morrison.  There were other deaths attributable to the weather…including traffic deaths and heart attacks from overexertion.

18-24

In 2005…a week of mid-winter unseasonably warm weather pushed high temperatures into the 60’s or more on all but one day.  During the period…the highest temperature of 70 degrees on the 20th was a new record maximum for the date.  Low temperatures remained above freezing on 4 of the days.

22-23

In 1982…wind gusts up to 101 mph were clocked at Wondervu. Wind gusts of 60 to 80 mph were common along the Front Range foothills from Boulder north.

22-26

In 1948…the longest period of snowfall on record (92 hours and 3 minutes) occurred in downtown Denver where a total of 13.6 inches of snow fell.  At Stapleton Airport…19.0 inches of snow fell…making it the heaviest snow in January and the 5th heaviest snow of record at that time.  North winds were sustained to a velocity of 23 mph on the 25th…but generally the winds were light throughout the storm.  The snow disrupted traffic…but street clearing was begun soon after it became apparent that the snow would be heavy.  Over the 5 days…temperatures ranged from a high of 48 degrees on the 22nd to a low of 1 degree on the 26th.  Most readings were in the teens and 20’s during the storm.

In 1872…a brisk northerly wind set in about noon…blew almost a gale about 6:00 pm…and continued brisk until night.  A light snow commenced during the late afternoon and continued all night.
 
In 1886…northwest winds were sustained to 40 mph in the city around sunrise.  A cold wave accompanied the strong winds.
