Denver and Colorado are certainly known for their varied weather conditions and as always, looking back at the weather history books highlights that. On these dates we have seen Arctic cold and balmy temperatures in the 70’s. We have seen hurricane force winds and even a rare December thunderstorm. And as one would expect, there has been plenty of snow.
2-17
In 1939…more than 2 weeks of unseasonably warm weather made the month the 3rd warmest on record. Seven daily temperature records were set…including the all time record high temperature for the month of 79 degrees on the 5th. Daytime highs were balmy with 14 days in the 60’s and 70’s. Low temperatures dipped to freezing or below on only 5 days. The period was dry with only a trace of snow on the 12th.
3-15
In 1972…a protracted cold spell held an icy grip on metro Denver when maximum temperatures never reached above freezing for 10 consecutive days from the 3rd through the 12th and minimum temperatures dipped below zero on eleven consecutive days from the 5th through the 15th. Daily low temperature records were set with 15 degrees below zero on the 5th…17 degrees below zero on the 6th… And 18 degrees below zero on the 10th. Daily record low maximum readings were set with 3 degrees on the 6th and 6 degrees on the 9th. The very cold temperatures were caused by 3 to 5 inches of snow cover and a Canadian air mass.

In 1960…heavy snowfall totaled 12.0 inches over the 3 days with 5.1 inches on the 4th…5.2 inches on the 5th…and 1.7 inches on the 6th. Rain changed to snow early on the 4th and ended by early afternoon. Snow started again early on the 5th and continued through midday on the 6th. West northwest winds gusted to 30 mph on the 4th. Post cold frontal temperatures cooled from a high of 38 degrees on the 4th to a low of 7 degrees below zero on the 6th.

In 1883…a major snow storm hit the city. Heavy snow fell from 10:00 am on the 5th to 7:30 am on the 6th. The amount of snowfall was not recorded…but precipitation from melted snow totaled 1.75 inches…which would give an estimated snowfall of nearly 18 inches. Temperatures during the storm were in the 30’s…so some of the snow May have melted as it fell. However…railroads were blocked and telegraph lines were downed in all directions. Telephone wires and poles were nearly all broken down. The company manager estimated the damage at 30 thousand dollars. Northeast winds were sustained to 24 mph in the city.
In 1892…heavy snow totaled 6.2 inches in downtown Denver. Most of the snow…6.0 inches…fell on the 6th.
In 2001…high winds developed in the foothills northwest of Denver. Winds gusted to 74 mph at aspen springs. West- northwest winds gusted to 35 mph at Denver International Airport…where the temperature warmed to a high of 55 degrees on the 6th.

In 1978…a major storm dumped heavy snow across metro Denver. At Stapleton International Airport…snowfall totaled 8.5 inches…northeast winds gusted to 46 mph…and temperatures plunged from a high of 49 degrees on the 5th to a low of only 6 degrees on the 6th. Maximum temperature of 6 degrees on the 7th was a new daily record low maximum reading. Most of the snow…6.7 inches…fell on the 5th.
5-8
In 1983…high winds occurred in and near the foothills each day. Wind gusts to 63 mph were registered in Golden Gate Canyon on the evening of the 5th. On the evening of the 6th…winds knocked down trees…snapped power lines…and blew out windows across metro Denver. Gusts were clocked to 102 mph in southwest metro Denver…while wind gusts to 38 mph were recorded at Stapleton International Airport. On the 7th…winds overturned a tractor trailer near Castle Rock. After midnight on the 8th…gusts to 97 mph were reported in southeast Boulder. Wind speeds of 60 to 70 mph were reported in other parts of metro Denver.
