December 11 to December 17: This Week in Denver Weather History
This time of year snow is a common occurrence but in our look back at this week in Denver weather history we are struck by the lack of significant snow events in the history books for the period. What we do see instead are a number of high wind events, many of which caused widespread damage.
From the National Weather Service:
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.
8-12
In 1932…the second longest sub-zero period on record in Denver occurred. The temperature fell below zero shortly after 1:00 pm on the 8th and remained below zero for 92 hours until 9:00 am on the 12th. The lowest temperature recorded during this period was 13 degrees below zero on both the 9th and 11th. That temperature on the 11th was a record low for the date. High temperatures of 4 on the 8th…5 below zero on the 9th…1 below zero on the 10th… And 6 below zero on the 11th were record low maximum temperatures for those dates. Light north winds at 5 to 10 mph were accompanied by occasional light snow…which totaled only 2.2 inches.
9-13

The month of November 2016 was certainly an unusual one for Thornton. Despite a turn toward colder weather at the end, the extraordinary warmth at the start was the dominating feature. We did finally receive our first snow of the season although we are far behind normal for the season.
Dominating high pressure was a recurring theme for the first half of the month. This kept storm systems and colder temperatures at bay bringing unseasonably warm mercury readings. Every one of the first 16 days of the month saw temperatures in excess of 60 degrees, five saw readings warmer than 70 degrees and one even hit over 80 degrees.
A series of troughs and cold fronts finally brought an end to the record-setting warmth. After recording 81.5 degrees of the 16th, we followed with a 40.9 degree high on the 17th. The 17th also brought our first, and thus far only, snowfall of the season. The balance of the month saw things return to a more typical November weather pattern.
Thornton’s average monthly temperature for November 2016 came in at 43.9 degrees. This was far above Denver’s historical average for the month of 38.3 degrees. Out at the airport where the Mile High City’s official measurements are kept, the average came in warmer still at 45.1 degrees. That put November 2016 into the books at the 10th warmest November in Denver weather history.
Temperatures in Thornton ranged from the aforementioned high of 81.5 degrees on the 16th down to a low of 13 degrees on the morning of the 30th. DIA’s high was 80 degrees and its low 10 degrees, each on the same day as Thornton’s maximum and minimum. The 80 degree reading on the 16th was not only a record for the date but also the latest 80 degree temperature ever recorded in Denver.
In terms of precipitation, Denver averages 0.61 inches during the month of November. Thornton fell far short of that with a mere 0.24 inches of precip in the bucket. Out at the airport, Denver fared better with 0.52 inches.
Thornton recorded 2.2 inches of snow for the month while Denver ended with 1.7 inches. Both were far below the November average of 8.7 inches and comprise the only snowfall we have seen this season. The snow on the 17th was the third latest first seasonal snowfall on record in Denver.

The month of December brings with it the official start of winter and oftentimes, colder and snowier weather conditions. It however can also offer unseasonably warm temperatures and bone dry conditions. Given our recent mild and dry weather, we are certainly hoping for a change in the coming month.
Overall December’s monthly mean temperature of 30.0 degrees (1981 – 2010 averages) makes it our coldest month. Snow is always on everyone’s mind this time of year but December is only our 3rd snowiest month behind March and November with an average of 8.5 inches of the white stuff.
We closed out November quite wet and chilly and that is expected to continue into the first part of December. Long term models then point to a continuation of above normal precipitation but near normal temperatures.
December 4 to December 10: This week in Denver weather history
As we have seen in recent days, Old Man Winter oftentimes makes his appearance in earnest during the month of Denver. Looking back at this week in Denver weather history we can see that is not at all unusual.

Typically November is a quiet weather month with plenty of nice, fall days but it can also turn wet with healthy doses of snow and moisture. The wide variety of conditions can create picturesque scenes ranging from blue skies and snow-capped mountains to a wintry wonderland in the metro area.
November is the second snowiest month of the year so winter conditions are not unusual. Typically though, these bouts of cold are short-lived and normal daytime conditions are pleasant.
Outdoor activities continue to be quite popular during the month. The cooling temperatures do oftentimes lead to an increase in wildlife activity.
All of the above help lead to a month in which a wide variety of scenes, flora and fauna can be captured.

November 27 to December 3: This Week in Denver Weather History
Cold, snow and wind are the dominant conditions we see in our look back at this week in Denver weather history. All three are common this time of year and extremes with those conditions seem to be unusually common as well.
Among the highlights are numerous high wind events that not only caused damage but also injury to unprepared residents. Significant snowfall also appears many times including a storm in 1983 that shut down the city for the Thanksgiving weekend and left snow on the ground for 63 days.

We thought the daily high temperature record for November 16 would fall today and indeed it did. However the Mile High City also managed to tie the record for the warmest temperature ever recorded during the month of November.
At 1:24pm the station at Denver International Airport reported a mercury reading of 80 degrees.
This easily bested the previous record high temperature for November 16 of 77 degrees set in 1941.
Perhaps more notably, the reading also ties the all-time record high temperature for the month of November. The old mark was 80 degrees set on November 8, 2006. This is in turn the latest in the year an 80 degree reading has been tallied.
Here in Thornton, we were a bit warmer than DIA. Our temperature topped out at 81.5 degrees at 1:02pm.
Showcasing the wide swings of weather we experience here in Colorado is the fact that after these records today, high temperatures tomorrow won’t go very far into the 40s. Check out forecast for the latest.
