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.
Thanks to some late January snows, Denver’s seasonal snowfall has started to rebound but still remains below normal. February is only our sixth snowiest month so it may not provide much help on the precipitation 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.

While typically a cold month, January is oftentimes lacking in terms of weather drama. Living in Colorado however provides plenty of opportunity to capture a wide variety of weather-related imagery as we see in our January 2014 slideshow.
Slideshow updated January 31, 2014
In this, our first monthly photo slideshow, we feature photos that not only we have taken but also those taken by ThorntonWeather.com fans.
Throughout the month we will gather the images sent to us via email or shared with us via our various social media outlets and post them in the slideshow below.
With us only being one week into the month, great photos of sunsets, wildlife, pets and wintry conditions have emerged. We love them all!
Thanks to a snowy start and a similarly snowy finish, the month of January 2014 climbed onto the list of top 10 January snow measurements in the Mile High City.
Officially the month ended with 14.3 inches of snowfall as measured at Denver International Airport. It was just enough to bump January 1991 from the number 10 spot (14.1 inches).
Here in Thornton we received just a bit less as we saw 13.4 inches of the white stuff.
January is only our fourth snowiest month with an average of 7.0 inches (based on 1981 to 2010 normals). The snowiest January on record occurred in 1992 when 24.3 inches of snow fell.
Looking at the 2013 / 2014 snow season, January helped make up some lost ground from the previous dry months.
The seasonal total now stands at 22.4 inches, 5.4 inches below the long term average of 27.8 inches we normally receive by the end of January. Thornton’s seasonal total is a bit better but still below normal at 24.2 inches.
The stage is set for Thornton to receive its most significant snowfall of the season thus far. Up in the high country snowfall will be measured in feet.
Here at lower elevations current forecasts are calling for 5 to 10 inches between Thursday and Friday afternoon. Many variables are in play that could affect the total that is eventually realized but this is certainly our best shot at a heavy snow thus far in the snow season.
We will be monitoring monitoring the storm very closely and posting regularly to our Facebook page and Twitter feed. You can follow along in real time below. We are also on Google+ here.
In a very brief period of time the forecast for the next 48 hours has changed considerably. The latest data indicates Thornton and the Colorado Front Range may be receiving a healthy dose of snow starting Thursday afternoon and lasting into Friday.
Abundant moisture streaming in from the Pacific coupled with a series of cold fronts stands to bring a wintry blast to the area. While the arrival is still a good ways out and much could change between now and when it gets here, the potential for a significant snow event exists.
The National Weather Service has issued a Winter Storm Watch for the Denver metro area and western plains. In effect from 3:00 p.m. Thursday through 3:00 p.m. Friday, the watch cautions that heavy snow will be possible.
Total forecast amounts are in the 3 to 6 inch range for the Denver area and 5 to 10 inches in the foothills. Bands of heavier snowfall are possible and could serve to drive those totals up. The Weather Prediction Center is giving at least a 40% chance of snowfall greater than or equal to 4 inches in our area.
The arrival later in the day Thursday should help to mitigate impacts to tomorrow’s commute home. However if this pans out as forecast, Friday morning’s drive to work may be a rough one.
With those forecast snowfall amounts comes the caveat that there is the possibility for less snowfall than mentioned above. A strong jet is overhead and while we expect upslope winds to help create a sustained snow event, should downslope flow prevail amounts will decrease.

Another year is in the books and as we look back at 2013’s weather, we see Thornton – and indeed much of the state – saw cooler and wetter than normal conditions.
In terms of temperatures, Thornton saw an average overall annual temperature of 49.3 degrees. Out at Denver International Airport where the Mile High City’s official records are kept, the average was warmer at 50.1 degrees. By comparison, Denver’s 1981 to 2010 annual average temperature is 50.4 degrees.
Thornton recorded 47 days with temperatures at or above the 90 degree mark. At DIA 54 such days were recorded. Both were above the average of 40 90 degree days per year.
The hottest temperature recorded during the year in Thornton came on June 11th when the mercury climbed to 99.2 degrees. Denver’s hottest temperature of 100 degrees came on June 11th and July 11th.
At the opposite end of the thermometer, Thornton saw 175 days with low temperatures below freezing. Denver was very similar with 169 days with temperatures below 32 degrees. On average we expect to see 157 days below freezing.
Our coldest temperature in Thornton came last month on December 5th when the mercury dropped to -9.3 degrees. Denver’s occurred on the same date as the mercury at the airport dropped to -15 degrees.
Precipitation for 2013 came in well above normal thanks largely in part to the extraordinary amount of rain received in September.
In all, Thornton saw 21.67 inches of liquid precipitation in our bucket. Denver, as always drier due to the station being at DIA, saw 17.60 inches. Both were above the annual average of 14.92 inches.
Above and by far the wettest month of the year was September and was responsible for the above average precipitation numbers. Thornton saw 10.15 inches in the rain bucket that month alone, Denver 5.61 inches.
Snowfall during the calendar year ended up relatively strong thanks to healthy totals from February through April. Overall the rest of the months of the year saw below normal snowfall.
Thornton’s annual snow total came in at an even 70.0 inches. Denver bested us with 74.1 inches during 2013.
Denver’s 2013 / 2014 season however has started out dismally with only 8.1 inches so far in the Mile High City. Thornton ended December a bit better with 10.8 inches. Both are well below the long term average that would have us see 21.2 inches by the end of the year.

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 2013 hold for us? Indications are that we may very well continue the recent pattern of below normal temperatures and relatively dry conditions.
The best photos of 2013 as seen through ThorntonWeather.com’s lenses. View the slideshow below.
Colorado’s weather and scenery can certainly be dramatic and the past year has been no different. Armed with our camera, we captured hundreds of images and shared them with our readers.
While we are entirely amateur photographers, sometimes Colorado makes it hard to take a bad picture. Over the course of 2013 we took hundreds of photos, many of which were shared with you on Facebook, Google+ and Twitter.
Picking which of the images we liked the best was not easy. The subject matter ranged from weather to wildlife to expansive landscapes and even heavenly bodies.
As we sorted through we couldn’t help but notice the lack of real weather drama in the photos we took. While there were wildfires to our south and floods to the north, Thornton managed to escape the year relatively unscathed from Mother Nature’s wrath.
We also were unable to do any real storm chasing so severe weather imagery was lacking. Hopefully that can be rectified in 2014. 😉
When all was said and done we came up with 25 images that we thought were our best photos of the year. You can view them in the slideshow below. Leave a comment here or on our social media pages and let us know what you think.
Remember too that we love seeing your photos so be sure to share them with us!
Thornton and the Denver area closed out 2013 with a display of typically highly variable weather. We recorded some record low temperatures followed by unseasonably warm conditions. One thing that was lacking was snow.
The first three days of the month started out quite mild with highs well above normal. That changed quickly midday on the third as low pressure moved in bringing an extended Arctic blast.
For six straight days high temperatures remained stubbornly below freezing and lows dipped into the single digits. The cold snap was notable but not record-setting in terms of length. Two daily low temperature records were tied or broken however.
Warmer weather returned on the 10th as the mercury finally started to climb. Unseasonably warm temperatures became the rule for the next nine days that included a record high temperature on the 18th.
The last third of the month was a bit more variable with its ups and downs but overall warmer than normal conditions.
Overall Thornton’s monthly average temperature came in at 29.2 degrees. Out at Denver International Airport where the Mile High City’s official stats are recorded, it was a bit cooler with an average of 28.4 degrees. Both were below Denver’s December average of 30.0 degrees.
Thornton recorded nine days with high temperatures that failed to reach 32 degrees. On five days, low temperatures dropped below zero. Denver saw eight days with highs below freezing, six with lows below zero.
The warmest temperature of the month in Thornton came on the 18th when we recorded 66.8 degrees. Our coldest was -9.3 degrees on the 5th. Denver’s warmest day was on the 18th as well with a high of 68 degrees. Its lowest temperature was -15 degrees on the 5th.
Four temperature records were tied or broken in Denver.
The low temperature of -13 degrees on December 4th shattered the old record low for the date of -5 degrees last set in 2008. The following day, on December 5th, the low temperature of -15 degrees tied the record low last set in 1972.
The mild weather December 18 saw two records. The high of 68 degrees broke the previous high temperature record for the date of 66 degrees last set in 1979. Also, the day tied the record high minimum for the 18th of 40 degrees set in 1917.
Precipitation for the month of December 2013 was not as noteworthy as the temperatures. Thornton recorded only 0.24 inches in our bucket while Denver received 0.25 inches. Both were a good bit below the December average of 0.35 inches.
Snow was similarly less than extraordinary. Thornton measured 5.7 inches of the white stuff while Denver lagged that with 4.7 inches. Both totals were below the normal for December of 8.5 inches. Seasonal snowfall totals at this point are about half of what they normally are.
