This Week in Denver Weather History

This time period in November has been exceedingly eventful throughout Denver weather history.  Notable as usual are big wind events that have caused damage and injuries.  Snow of course is also quite present, including the Thanksgiving blizzard of 1983 which dumped an astounding 21.5 inches of snow on the Mile High City.

From the National Weather Service:

Thornton’s November weather preview: Transition to winter weather begins in earnest

Thornton's November weather previewThe weather during the month of November in Denver metro area can offer just about anything.  While it is normally a quiet month, it can be prone to extremes.

November has historically been one of Denver’s snowiest months and major snowstorms are not entirely uncommon.  However conditions can also be quite dry.

Temperatures during the month continue to cool as we get closer to winter and by the end of the month the low temperatures routinely dip to 20 degrees or below.  At times it can in fact bring conditions more like what we see in January.

Get all the details on November’s weather and what we can expect in our complete preview here.

Denver sets record high temperature for November 4

Record High Temperature

Our mild weather continued today and set another record, the third in the past two days.

Officially, as measured at Denver International Airport, the high temperature today topped out at 77 degrees. This just beat out the previous record high for November 4th of 76 degrees set over 100 years ago in 1915.

Thornton was similarly warm but just a touch cooler, recording a high of 75 degrees for the second day in a row.

Denver ties one warm weather record for November 3, breaks another

Record High Temperature

This mild weather has been quite nice but it certainly is not normal for this time of year with mercury readings well above average. The Mile High City saw two weather records tied or broken on Tuesday.

As measured at DIA, Denver saw a high temperature of 79 degrees. This tied the record high for November 3rd last set in 1915.

Additionally, a record high minimum was set as the low temperature only dropped to 48 degrees. This bested the old record of 46 degrees set in 1940.

Here in Thornton, we were cooler across the board with a high of 75 degrees and a low of 37 degrees.

November 1 to November 7: This week in Denver weather history

This Week in Denver Weather History

As we enter Denver’s second snowiest month, we of course see plenty of events involving that dominant weather condition.  Sadly we also see two occasions when the winter-like weather turned deadly.

On the 2nd:

In 1939…a trace of snow fell over downtown Denver.  This snow…along with a trace of snow on the 9th…was the only snow of the month…ranking it…along with other months…the second least snowiest November on record.

The winter storm closed schools and disrupted all forms of transportation in the city.  The greatest depth of snow on the ground was 28 inches at the airport.  The duration of the snowfall…from 4:22 am on the 2nd to 3:08 am on the 5th… A total of 70 hours and 46 minutes…is the second longest period of continuous precipitation on record and the second heaviest snowfall of record at the time in Denver.  The 17.7 inches of snowfall on the 2nd and 3rd was the greatest 24- hour snowfall ever recorded during the month of November. Buses and street cars had a difficult time…and many cars were abandoned along roadsides and streets for several days. Secondary roads in rural areas were blocked for 2 to 3 weeks.  Several buildings in the city collapsed or were damaged from the weight of the heavy snow.  Football games were canceled.  Livestock losses were high over eastern Colorado.  The precipitation from this storm alone exceeded the greatest amount ever recorded in Denver during the entire month of November previously.  The precipitation recorded downtown was 2.03 inches…and the previous record for the entire month of November was 1.95 inches in 1922. North winds were sustained to 26 mph on the 2nd.

November 2019 weather recap: Another cold, snowy month for Thornton

For the second month in a row, Mother Nature kept us cold and delivered a healthy dose of snow. Thornton experienced its second coldest November of the past 13 years and the snowiest of the past 13 years.

The month started out chilly but soon saw things stabilize and turn seasonal. Then, the 8th and 9th offered up our two warmest days of the month with readings of 71 and 79 degrees respectively. We quickly chilled out and saw our first snowfall of the month on the 9th although it was minimal.

From the 12th to the 19th, weather was relatively calm and temperatures for the most part warmer than normal.

After that, things went downhill with most of the balance of the month seeing temperatures well below normal. Light snow on the 20th, 21st and 22nd was followed by our most significant storm of the season on the 26th.

Thornton saw an overall overage temperature for November of 35.6 degrees. This was a good ways below the long term Denver average for the month of 38.3 degrees. Out at Denver International Airport where Denver’s official measurements are taken, the average temperature for the month was 36.2 degrees.

Temperatures in Thornton ranged from a high of 79 degrees on the 9th down to a low of 2 degrees on the 27th. Out at the airport, Denver saw its warmest reading of 77 degrees on the 9th also and its coldest temperature of -2 degrees on the 27th. The high temperature on the 9th was a record high for the date.

A generous amount of precipitation was received with Thornton recording 1.46 inches of rain and snowmelt. Denver lagged a bit with 1.31 inches. Both readings were well above the long term Denver average of 0.61 inches for November.

In terms of snowfall, the Mile High City averages 8.7 inches in November. Thornton’s reading of 16.7 inches and Denver’s of 13.7 inches easily bested the average.

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.

Thornton’s November weather preview: A month that can be prone to extremes

Thornton's November weather previewThe weather during the month of November in Denver metro area can offer just about anything.  While it is normally a quiet month, it can be prone to extremes.

November has historically been one of Denver’s snowiest months and major snowstorms are not entirely uncommon.  However conditions can also be quite dry.

Temperatures during the month continue to cool as we get closer to winter and by the end of the month the low temperatures routinely dip to 20 degrees or below.  At times it can in fact bring conditions more like what we see in January.
