The month of December can offer everything from bone dry conditions to bone chilling cold and monstrous snowstorms.  The weather and wildlife all afford an abundance of photo opportunities as our December photo slideshow shows.

Leaves have fallen from trees now and the landscape can sometimes look quite stark.  However it only takes a quick shot of snow to change that picture greatly.  Throw in gorgeous sunrises and sunsets, plenty of wildlife big and small, kids playing and much more and the month can be quite colorful and eventful.

Looking back at an unforgettable holiday – Denver’s Christmas Eve Blizzard of 1982

As Christmas approaches everyone reflects on the past and for longtime Denver residents that oftentimes means remembering one of the most significant winter storms in the Mile High City’s history – the Christmas Eve Blizzard of 1982.  This major winter storm has become the one by which all others are compared not only due to its record-setting impact but also due to its timing being near Christmas.

As Christmas 1982 approached, forecasters were predicting a white Christmas several days beforehand but most were expecting a moderate snowfall of 6 inches.  Two days before Christmas Eve though, the picture began to change.  On the 22nd a Pacific cold front came ashore in California bringing severe rain, high surf and even hurricane force winds.  As it moved east over higher terrain, it dumped 2 feet of snow in the Wasatch Mountains near Salt Lake City.

At about that same time, jet stream winds were forming a trough of low pressure over the southeastern plains of Colorado.  The counterclockwise motion of the trough began to pull moist air into the state.  Further east Kansas and Oklahoma experienced severe thunderstorms and even tornadoes.  The winds set the stage for strong upslope conditions along the Front Range.

Rain changed to snow on the plains and shortly before midnight on the 23rd, a full blown blizzard had developed.  Denver woke to snow on the ground the morning of Christmas Eve but the storm was just getting started.  Snowfall rates of 2 – 3 inches per hour were the norm during the day and winds screamed at 50mph causing wind chill temperatures to plummet to as low as -35 degrees.  As conditions continued to deteriorate throughout the day, the gravity of the situation began to be realized.

Astronomical winter arrives Thursday, offers up the shortest day of the year

The Winter Solstice
Winter officially begins at 8:27pm MST on Thursday, December 21, 2023.

Astronomical winter arrives in Thornton Thursday evening and with the solstice also comes the shortest day of the year.

Winter officially begins at 8:27pm MST on Thursday, December 21, 2023.

The Winter Solstice occurs when the North Pole is tilted at its furthest from the sun – 23.5 degrees away. This results in the shortest day of the year in the Northern Hemisphere.

Here in Denver, with sunrise at 7:17am and sunset at 4:38pm, our day Saturday will be 9 hours, 21 minutes and 14 seconds long.

The following day, Friday, it will be about a second longer and each day from now through to the Summer Solstice in June will get gradually longer as well.

While we have a short day on the solstice, it is nothing like what will be experienced in the Arctic Circle.  Areas north of there to the North Pole will have no direct sunlight at all.  Conversely, areas south of the Antarctic Circle toward the South Pole will have 24 hours of daylight and have a midnight sun.

Did you know that there is a difference between the astronomical seasons that we are discussing here and meteorological seasons?

Meteorological seasons differ slightly and are geared toward matching the calendar with the annual temperature cycle. This is done primarily for meteorological observing and forecasting and in many ways it is more logical than the astronomical seasons.

For the Northern Hemisphere, the meteorological spring covers the months of March, April and May. Summer brings the hottest months of the year and so meteorological summer is June, July and August. Meteorological fall then is September, October and November followed by the coldest months of December, January and February as meteorological winter.

Denver ties record high temperature for December 19

Record High Temperature

We knew going into today this was a possibility and indeed, it happened.

As measured at Denver International Airport, the official high temperature for the Mile High City reached 67 degrees. This ties the record high for the date last set more than 100 years ago in 1917.

Here in Thornton, we were just a touch warmer with a high of 68 degrees. This was the warmest December 19th since ThorntonWeather.com came online in 2006.

November 2023 weather recap: Thornton gets another mild, dry month

For the second month in the row, Thornton saw a period of temperatures above normal and precipitation below normal. Were it not for a cold snap and snow to end the month, it would have been much worse.

Most of November saw a continuation of the mild, dry weather we saw in October. For the first three weeks, temperatures were largely above normal and precipitation was virtually non-existent. In fact, 19 out of the first 22 days of the month saw mercury readings above normal and a mere 0.02 inches had been recorded in the rain bucket and we had no snow.

Mother Nature finally changed course and chilled us out and brought our first snow of the month during the last week. We saw a few days with well below normal temperatures and 4.3 inches of snowfall were recorded over a two-day period.

Thornton’s average temperature for November 2023 came in at 42.2 degrees. This was well above our 17-year running average for November of 39.7 degrees. Temperatures ranged from a high of 79.8 degrees on the 5th down to a low of 11.7 degrees on the 26th.

Out at DIA where the Mile High City’s official measurements are taken, it was similarly warm. Denver had an overage temperature for the month of 43.2 degrees, again, well above their average of 39.4 degrees.

In terms of precipitation, Thornton saw a mere 0.20 inches of liquid precipitation during the month. This was less than half of the 0.47 inches running November average and tied for the third driest November of the past 17 years.

Denver recorded 0.18 inches out at the airport. Far below their long term November average of 0.64 inches.

Snow was below normal both here in Thornton and at DIA. Thornton recorded 4.3 inches, a good bit below the 5.7 inch November average of the past 17 years. Denver saw less than us with 2.9 inches, far below their long term November average of 7.3 inches.

Thornton’s December 2023 preview: Winter arrives, typically with cold and snow

Thornton, Colorado's December Weather Preview

Recent months have, overall, been warmer and drier than normal.  Last month initially brought more of the same but then took a turn toward colder temps and offered up some much-needed snow.  What will December hold for us?

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 31.2 degrees (1991 – 2020 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 8.0 inches of the white stuff.

Get all the details on Thornton’s December weather including a look back at historical events and a look at the long range forecast in our December weather preview here.

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.
