The month of March in Denver is usually one that is welcomed heartily by residents. We begin to shake off the cold of winter with warmer temperatures and calmer conditions. That does not mean we are done with snow and cold by any means.
March usually offers healthy snowfall giving us an opportunity to add to our seasonal totals. While there is good snow potential in March, the month also typically brings much warmer temperatures.
March is historically Denver’s snowiest month and brings about 20% of our annual snowfall. Heavy, wet spring snow storms can oftentimes bring the entire month’s snowfall total in one monstrous snow.
We also start the transition to spring and severe weather season and the month typically brings our first thunderstorms of the year. Temperatures climb throughout the month and by the end our average daytime highs are near 60 degrees.
Cold and snow. Those were certainly the operative words for the month of February 19. Thornton recorded its coldest February in the past 12 years and its snowiest month overall since March 2016.
Mild temperatures started things off for the first four days of the month and fooled us into thinking of an early spring. Those dreams were soon crushed though as the first extended period of below normal temperatures arrived on the 6th. Six straight days of below normal temperatures then arrived as did our first shot of snow for the month.
We rebounded briefly for a four day period from the 12th to the 15th with mild temperatures. Once again though, the mercury plunged delivering 13 straight days of below normal temperatures and five days of measurable snowfall.
Thornton recorded an average temperature for the month of 26.3 degrees. This was our coldest February since ThorntonWeather.com came online in 2007 – by more than two degrees. Out at Denver International Airport where the Mile High City’s official readings are taken it was slightly warmer with an average of 28.0 degrees. Both were well below Denver’s long term February average of 32.5 degrees for February.
While certainly cold, neither average reading for the month could crack Denver’s list of top 10 coldest Februarys.
Thornton saw its warmest mercury reading for the month of 62.3 degrees on the second. Its coldest reading of -7.7 degrees came on the 7th of the month. Denver saw a maximum of 65 degrees on the 3rd and its low of -11 degrees on the 7th.
February is usually a dry month with Denver averaging 0.37 inches of liquid precipitation. Thornton recorded 0.60 inches this year while Denver saw 0.72 inches.
Similarly, snow was a good bit above normal for February as well. Thornton saw 11.2 inches of the white stuff while out at the airport 13.4 inches was recorded.

February signifies the start of the climb toward warmer temperatures for the year. Cold and snow though do intrude but, coupled with milder conditions, there are lots of photo opportunities as can be seen in our monthly slideshow.
The month is one of our least snowiest of the year but it isn’t unusual to see the landscape blanketed in white. Warming temperatures through the month can bring the onset of spring fever and gives residents the opportunity to enjoy some prolonged time outdoors on the mild days.
Cold or mild, snowy or dry, our scenery is almost always gorgeous – and photo worthy.

February in Colorado typically brings to an end an extended period when average temperatures are at their lowest. Winter begins to loosen its grip and temperatures get warmer but precipitation is not a particularly common event during the month.
Thus far our snow season has been relatively dismal with the seasonal total in Thornton more than 10 inches below average. In the high country, the snowpack is not faring much better. February is only our sixth snowiest month so we may not see much snowfall for the balance of the month.
Temperatures however do usually see a nice rebound during the month. Average high temperatures climb from an average of 44 degrees at the start to 50 degrees by the end of February.
Finally! Our winter thus far had been quite dry so seeing some precipitation in January was a very welcome change. Temperatures were just a bit above normal.
Overall, the month was short on any sort of real weather drama with no major storms or particularly notable temperature extremes. However, a series of storm systems did give us a bit of a roller coaster of weather with five different snow events over the month.
January started out with a very cold New Year’s Day but soon saw warmer temperatures arrive. Our first snow came on the 11th and 12th. This was followed by some smaller events and finally our biggest snowfall of the month on the 28th.
Thornton’s average temperature for the month came in at 31.3 degrees. This was a bit warmer than Denver’s long term overage for January of 30.7 degrees. Out at DIA where Denver’s official readings are taken, it was a bit warmer with an average of 32.0 degrees.
Our mercury readings ranged from a low of 2.2 degrees on the 1st and the 2nd to a high of 61.1 degrees a few days later on the 4th. Denver’s lowest reading was 5 degrees below zero on the first and its warmest of 62 degrees came on the 4th.
In terms of precipitation, Denver averages 0.41 inches of liquid precipitation during January. Thornton easily bested that with an even 1 inch in our bucket. Denver was above average as well with 0.75 inches.
Snowfall in Thornton saw above normal levels with a total for the month of 10.9 inches. Denver, as usual, lagged with 6.2 inches of the white stuff. The 30 year average for Denver for January is 7.0 inches.

As one of our coldest months, January can be a good month to hibernate inside and avoid the outdoors. But, like any month in Colorado, photo opportunities abound as our monthly slideshow demonstrates.
Snow is not normally dominant in the month but when it does fall, it can create a beautiful blanket of white. Throw in the amazing sunrises and sunsets we receive in the middle of winter as well as wildlife and a host of other subjects and the imagery can be quite beautiful and stunning.

Well, that was fun, eh? Well, probably not for those stuck in traffic when the snowstorm hit this morning.
The storm over-performed big time, far exceeding forecasts. Upslope flow pushed the system against the mountains and kept it in place over the Front Range.
Our east webcam captures it all in a time lapse.
Snow begins at about 3:00am and continued through much of the morning. By the end of the day though, blue skies returned and the snow was melting. We recorded 4.2 inches here but know many spots, particularly to the west, got more.
Thornton’s December was lacking in terms of any sort of real weather drama. Temperatures were relatively mild for much of the month and precipitation was fleeting.
Above normal temperatures were the general rule for the first part of the month. It was only the last week of the month when Arctic air arrived and we saw temperatures drop considerably. We saw only two measurable snow events, neither of which amounted to much.
Overall, Thornton’s average temperature for the month was 30.8 degrees. This was nearly a full degree above Denver’s long term December average of 30.0 degrees. Out at DIA where the Mile High City’s official measurements are taken, it was a good bit warmer with an average of 32.5 degrees.
Temperatures in Thornton ranged from a high of 60.6 degrees on the 21st down to a low of 4.5 degrees on the morning of the 29th. Denver’s warmest reading of 63 degrees also came on the 21st and its coldest, 0 degrees, on the 31st.
Denver averages 0.35 inches of precipitation during December. Thornton fell well short with a mere 0.07 inches. Out at the airport, even less was realized with 0.03 being recorded. This puts December 2018 into the books as one of the driest Decembers ever recorded.
Thornton recorded a mere 0.9 inches of snow during the month, the majority of which fell on the last day of the month. Denver saw 0.5 inches, all on the 31st. Both fall well short of the long term Denver average for December snowfall of 8.5 inches and put December 2018 on the list of the ten least snowy Decembers recorded.
Ten least snowy December’s in Denver weather history:
TRACE – 1905, 1906, 2002
0.1 – 1928
0.4 – 1890
0.5 – 1935, 2018

As we begin the new year the winter chill begins to set in. While January can see its share of extremes, the month historically sees stable temperatures and is usually relatively dry.
January ranks as the second coldest month in Denver next to December with average temperatures remaining virtually the same from the start to the end of the month.
In terms of snowfall, the month only ranks as the fourth snowiest and it is not uncommon for it to be quite dry.
What does January 2019 hold for us? Follow the link to find out.
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.
