Back to back: Denver sets a record high temperature for second day in a row

Friday, October 28th, 2016 4:21pm MST

Record High TemperaturesFollowing on yesterday’s record-setting performance, the mercury once again rose to levels never before seen on this date.

At 12:53pm the station at Denver International Airport reported 82 degrees.  This easily bested the previous record for October 28 of 80 degrees last set in 1994.

Here in Thornton we were actually a bit warmer reaching 83 degrees at 3:34pm.

This is the third record high temperature recorded this month.  The first came on October 15 and the second just yesterday.

At this time it is certain that October 2016 will go into the record books as one of the 10 warmest Octobers in Denver history.  Where it ends up on the list is yet to be determined but it is likely to be around the fourth or fifth warmest.

Thornton’s weekend to see continued warm, dry weather conditions

Friday, October 28th, 2016 4:59am MST

The waning days of October are set to bring more of the same unseasonably warm and dry weather we have seen for the past few weeks. Friday once again has the potential to see record highs before we cool down just a bit Saturday and Sunday.

For today we will have a good bit of cloud cover due to upper level moisture coming from the southwest. That however will not translate into precipitation and we will be dry. Temperatures today will be greatly dependent on the cloud cover’s influence. We may top out at or just a bit above 80 degrees but if the clouds provide enough coverage, we may stay in the 70s. The record high for today’s date is 80 degrees, last set in 1994.

Saturday is going to see a bit more sun and slightly cooler temperatures. Look for mostly sunny skies above as we head for a high in the mid-70s.

We’ll close out the weekend on Sunday with a day much like Saturday. Calm, dry and mild conditions will continue.

Have a great weekend!

Denver sets new record high temperature for October 27

Thursday, October 27th, 2016 5:39pm MST

Record setting high temperatures in Thornton.For the second time this month, the Mile High City broke a record high temperature.  The new mark beats a reading that had stood for 50 years.

At 3:23pm today the mercury at Denver International Airport topped out at 83 degrees.  This easily bests the previous record for this date of 80 degrees last hit in 1966.

Here in Thornton we were just a notch cooler with a high of 82 degrees.

This is the second time this month Denver set a record high. The first came on October 15 with a reading of 85 degrees that beat the previous mark of 83 degrees.

We may not be done setting records either.  The record high for tomorrow is 80 degrees as well, set in 1994 and years prior.  Right now the forecast calls for us to reach that same temperature although cloud cover may prevent that from happening.

WikiLeaks email details bullying, silencing of CU professor on climate change

The latest batch of emails released by WikiLeaks from John Podesta, Hillary Clinton’s campaign manager, contain a local connection.  A message received by Podesta details how climate change alarmists launched a concerted effort to keep a University of Colorado professor from publishing his views on manmade climate change.

Holding degrees in mathematics, public policy and political science, Roger Pielke, Jr. is a well-respected professor at CU.  Using statistical analysis, he has authored many papers and books debunking some of the more outrageous claims purveyors of the manmade climate change theory use to scare the populace.

Pielke apparently was seen as a threat to alarmists after publishing a story to fivethirtyeight.com in March 2014 disputing the claim that disasters are becoming more expensive due to climate change.

The professor used imperial data to determine, “When you read that the cost of disasters is increasing, it’s tempting to think that it must be because more storms are happening. They’re not. All the apocalyptic “climate porn” in your Facebook feed is solely a function of perception. In reality, the numbers reflect more damage from catastrophes because the world is getting wealthier. We’re seeing ever-larger losses simply because we have more to lose — when an earthquake or flood occurs, more stuff gets damaged.”

This did not fit the narrative of those that believe manmade climate change is the greatest threat to the Earth of the century.

Judd Legum, editor of ThinkProgress, sent an email to Podesta as well as billionaire Tom Steyer detailing Legum’s organization’s efforts to silence Pielke.  He brags that ThinkProgress was successful in ensuring, “Pielke never wrote another piece on climate change for 538.”

Steyer is a name that should be familiar with Coloradans.  The San Francisco-based billionaire and environmental activist has spent millions of dollars in Colorado elections, trying to influence their outcomes.

The Earth (NASA)Ironically, Pielke has been a voice of reason and moderation in the sometimes-raucous debate about manmade climate change.  He actually favors a carbon tax and has advocated for removing any incentives for fossil fuels and replacing them with a push for renewable energy sources.

Pielke told the Boulder Daily Camera, “They were ultimately successful in removing an academic from working on a topic,” as he has moved on to other areas of study.  There’s, “nothing like a political witch hunt to help you focus on career priorities,” he said.

“It spells out in black and white … that there was an organized, politically motivated campaign to damage my career and reputation, based on a perception that my academic research was thought to be inconvenient.”

The fact that a member of academia could be silenced is troubling but it also fits the new way that climate change alarmists have chosen to battle those that disagree with them: Don’t debate the topic on its merits, instead simply shut down the opposition.

Thursday to bring lots of sun, potentially record-setting temperatures

Thursday, October 27th, 2016 5:03am MST

Writing the weather forecasts this month has been quite repetitive with minor differences day to day. That trend continues today as we will see dry, calm conditions and temperatures pushing toward the record high.

We start out with sunny skies and other than a few clouds late today, the sun will shine unabated. Winds will be calm, conditions dry. Look for highs today to top out around 81 degrees. The record for today’s date is 80 degrees last set in 1966 so it will be in jeopardy of falling.

Keep an eye on the rising mercury here.

Lots of sun and very mild temperatures for Wednesday

Wednesday, October 26th, 2016 5:08am MST

High pressure has re-built over the region and that is going to continue to be the driving factor in our weather not only today but through the end of the week. Dry conditions and unseasonably warm temperatures will be the end result.

We start out the day with clear skies and you can look forward to a healthy dose of sun above throughout. Conditions will be calm and dry as we head for a high temperature in the mid-70s. Average for the date is 61 degrees.

Looking ahead, we will return to pushing the 80 degree mark tomorrow and Friday then cool slightly to the mid-70s for the rest of the weekend.

ThorntonWeather.com celebrates its 10th birthday

Tuesday, October 25th, 2016 10:00am MST
Keeping an eye on the sky since October 2006. ThorntonWeather.com is now beginning its 10th year of operation.

Keeping an eye on the sky since October 2006. ThorntonWeather.com went live on the Internet 10 years ago.

It is hard to believe but it was 10 years ago today on October 25, 2006 that the digital switch was thrown and the first bits of live weather data from our weather station were fed to the Internet.  ThorntonWeather.com was born!

Since that date, we are extremely proud of what the site has become – an indispensable community resource for north Denver metro area residents, businesses and governmental agencies.

On the one year anniversary of the site’s launch, we were receiving on average 750 unique visitors a month.  On the second anniversary that had grown to around 5,000 visitors a month.  For 2016 we are on pace to average well over 25,000 per month!

The response has been absolutely overwhelming to say the least.

We launched the site simply because we wanted to know what was going on with the weather in Thornton and the north Denver metro area.  We don’t live downtown, we don’t live at DIA and the differences in weather between Thornton and those other locations can be considerable.  Apparently many of you agree!

Our site has not only grown in terms of visitors, but perhaps more importantly in terms of the amount of information available.  Certainly we provide the basics of live weather conditions, radar and forecasts.

  • Did you know ThorntonWeather.com is a completely non-profit venture run by a Thornton resident?  We are self-funded but do occasionally receive help from members of the community, something which allows us to keep things up and running. Learn more about how you can help here.

Far more than that, we now have educational information about various weather dangers, historical climate information, satellite imagery, webcams and so much more.  Our news and blog section is continually updated with the latest news and information including items important to the community.

Put simply, there is no other media outlet in the state that provides as much weather news, information and content as we do!

Since our launch we have became very ‘social’ with a growing Facebook page, a Twitter feed and a presence on Google +.  Interacting with our visitors is an integral part of our site and something we enjoy greatly.

  • Stay up to date with Thornton’s weather: Be sure to ‘like’ us on Facebook, follow us on Twitter and add us to your Google+ circles.

We’re just ‘weather geeks’ that love the weather and love our community.  Running ThorntonWeather.com can be a bit expensive and it is time consuming to maintain and operate it but it is worth it.

We’d like to thank all of our visitors for your support in the past and we look forward to continuing to be the best, truly local source for Thornton weather.

Tuesday cools a bit, brings just a slight chance for a sprinkle

Tuesday, October 25th, 2016 5:18am MST

Tuesday cools a bit, brings just a slight chance for a sprinkle. A weak system is moving through today and that is going to mix things up with our weather but only slightly.

Look for cooler temps and maybe a sprinkle or two. We start out the day with mostly cloudy skies then will see that cloud cover ease as the day progresses leading to mostly sunny skies by mid to late afternoon. Temperatures today will be topping out in the low to mid-70s, cooler than yesterday but still well above normal.

In terms of precipitation, we have just a slight chance to see some showers from now into the early afternoon. Unfortunately, activity isn’t likely nor is any that develops expected to amount to much.

After today, we continue the mild weather and expect dry conditions through the end of the week.

Thornton’s mild, dry weather continues Monday

Monday, October 24th, 2016 5:07am MST

Very little change in store for our overall weather pattern today. In fact, we will be seeing more of the same through the week.

Today we start out with mostly sunny skies. We’ll see some cirrus clouds above of varying thicknesses as the day progresses. Temperatures will be climbing to a high in the mid-70s, well above the average for the date of 62 degrees.

For the balance of the week, mercury readings in the 70s will be the rule and conditions dry other than just a slight chance for showers tomorrow and tomorrow night.

October 23 to October 29: This Week in Denver Weather History

Sunday, October 23rd, 2016 7:00am MST
This Week In Denver Weather History

October 23 to October 29: This Week in Denver Weather History

It’s not quite Halloween but leading up to the holiday we see plenty of  ‘scary’ weather in our look back at this week in Denver weather history. High winds are relatively commonplace and so too are major snowstorms. One recent event in 1997 dumped 14 to 31 inches of the white stuff on the metro area.

From the National Weather Service:


In 2003…an extended warm spell resulted in 5 new temperature records. The high temperature of 84 degrees on the 18th equaled the record high for the date. High temperatures of 86 degrees on the 19th…83 degrees on the 21st…and 84 degrees on the 22nd were record highs for the dates. Low temperature of 49 degrees on the 23rd was a record high minimum for the date. Low temperatures during the period were in the 40’s and lower 50’s.


In 1906…heavy snowfall totaled 22.7 inches in the city over the 5 days. Rain changed to snow on the evening of the 19th…and snow continued through the late afternoon of the 23rd. The heaviest amount of snowfall…16.0 inches…fell from 8:00 pm on the 20th to 8:00 pm on the 22nd. The most snow on the ground was 13.3 inches on the evening of the 23rd. This was the first snow of the season and the only snow of the month. Winds during the storm were from the north at sustained speeds of 20 to 30 mph each day. Temperatures during the storm were generally in the 20’s.


In 1914…post-frontal rain changed to snow. Precipitation totaled 2.72 inches…most of which was in the form of moist snow which melted as it fell in the business section of the city. About 3 inches of snow was measured on lawns in the residential areas on the morning of the 24th. Official snowfall totaled only 0.4 inch downtown… But an estimated 8.0 inches of snow melted as it fell. North to northeast winds were sustained to 29 mph with gusts to 30 mph on both days.

In 1975…a vigorous cold front moving across metro Denver followed by strong northeast winds gusting to 52 mph produced billows of blowing dust and plunged the temperature 21 degrees in an hour. The surface visibility was reduced to 1/4 mile in blowing dust at Stapleton International Airport. The temperature cooled from a daily record high of 81 degrees to a low of 38 degrees by day’s end. The first snowfall of the season totaled 2.7 inches on the 23rd. This was the only measurable snow of the month at Stapleton International Airport.

In 1995…heavy snow fell on the Palmer Ridge south of Denver and in the foothills west of Denver where snow amounts ranged from 4 to 8 inches. Sedalia…south of Denver… Received 8 inches of snow. Winds strengthened on the plains and produced blizzard conditions…reducing surface visibilities to less than 1/4 mile. I-70 was closed from just east of Denver at Gun Club Road to the Kansas border. Ten inches of snow fell at Strasburg east of Denver where north winds at sustained speeds of 35 to 45 mph with gusts as high as 60 mph produced 2 to 4 foot drifts. Snowfall totaled only 2.2 inches at the site of the former Stapleton International Airport. North winds gusted to 51 mph at Denver International Airport.


In 1876…skies were fair…but winds were sustained to 48 mph.

In 1942…a major storm dumped 10.2 inches of snow over downtown Denver. Post-frontal northeast winds were sustained to only 13 mph.

In 1955…the first snowfall of the season and the only measurable snow of the month dumped 4.1 inches of snow on Stapleton Airport. This was the single heaviest October snowfall in 13 years since 1942. The storm also brought the first sub-freezing temperatures of the season when the temperature dipped to a low of 25 degrees.

In 1956…southwest winds gusted to 53 mph and produced some blowing dust at Stapleton Airport.

In 1967…a northwest wind gust to 51 mph was recorded at Stapleton International Airport. In downtown Boulder… Winds were sustained at 20 mph with gusts in excess of 40 mph.

In 1981…strong winds occurred in the foothills. Wind gusts to 70 mph were reported at Wondervu.


In 1887…the first measurable snowfall of the season totaled 3.1 inches. North winds to 20 mph were recorded on the 23rd. This was the only measurable snow of the month.

In 1932…post-frontal snowfall from the late evening of the 23rd continued through the late afternoon of the 24th and totaled 6.2 inches. Southeast winds were sustained to 25 mph with gusts to 26 mph on the 23rd. Temperatures cooled from a high of 68 degrees on the 23rd to a low of 25 degrees on the 24th…the coldest reading of the month that year. Many trees that had not shed their leaves became heavily laden by the wet snow. Many branches were broken… And a few trees toppled under the weight of the snow. The landscape became one of rare beauty.


In 1956…southwest winds gusted to 56 mph and produced some blowing dust at Stapleton Airport. A cold front produced a thunderstorm with 1/8 inch hail. Rain later changed to snow. Precipitation totaled only 0.11 inch and snowfall only 0.3 inch.

In 1973…strong winds raked the eastern foothills…causing damage in Boulder and Jefferson counties. The heaviest damage occurred in the Boulder area where 20 to 25 mobile homes were hit…some power and telephone lines were blown down…and a store was damaged. A wind gust to 76 mph was recorded in Boulder at the National Bureau of Standards. Northwest winds gusted to 46 mph at Stapleton International Airport.


In 1921…rainfall totaled 0.35 inch overnight behind an apparent cold front. North winds were sustained to 40 mph with gusts to 46 mph on the 25th. Temperatures plunged from a high of 73 degrees on the 24th to a low of 39 degrees on the 25th.

In 1923…rain overnight changed to snow during the morning. The heavy snowfall accumulated to 12.0 inches before ending on the morning of the 25th. Post-frontal north winds were sustained to 22 mph with gusts to 23 mph on the 24th.

In 1997…one of the worst and deadliest blizzards of the decade developed over eastern Colorado as deep east to northeast flow associated with a vigorous upper level low pressure system over the Four Corners…combined with a strong arctic air mass over the central great plains. Snowfall totals across metro Denver ranged from 14 to 31 inches. The heaviest snowfall occurred in the foothills west and southwest of Denver where 2 to 4 feet of snow were measured. Sustained winds to 40 mph with gusts as high as 60 mph produced zero visibilities and extremely cold wind chill temperatures from 25 below to 40 below zero. Winds whipped the snow into drifts 4 to 10 feet deep. Several major and interstate highways were closed as travel became impossible. Red Cross shelters were set up for hundreds of travelers who became stranded when they had to abandon their vehicles. Four people died in northeastern Colorado as a result of the blizzard. None of the deaths were in metro Denver. At Denver International Airport…4 thousand travelers were stranded when the airport was forced to shut down. At least 120 cars were abandoned along Pena Blvd….the only arterial leading into and out of dia. The blizzard cost air carriers at least 20 million dollars. Thousands of cattle died in the storm over northeastern Colorado…resulting in losses totaling 1.5 million dollars. Some of the more impressive snowfall totals included: 51 inches at Coal Creek Canyon; 48 inches at Silver Spruce Ranch…near Ward; 42 inches at Intercanyon…in the foothills southwest of Denver; 37 inches at Sedalia; 35 inches at Aspen Springs and Conifer in the foothills west of Denver; 31 inches at Eldorado Springs… Southeast Aurora…and Englewood; and 30 inches on Table Mesa in Boulder. Snowfall totaled 21.9 inches at the site of the former Stapleton International Airport…setting a new 24-hour snowfall record of 19.1 inches for the month. Snowfall totaled only 14 inches at Denver International Airport where north winds gusted to 39 mph on the 24th. High temperature of only 21 degrees on the 25th equaled the record low maximum for the date first set in 1873. Low temperature of only 3 degrees on the 26th set a new record minimum for the date.


In 1925…a vigorous cold front produced north winds sustained to 42 mph with gusts to 52 mph. Post-frontal snowfall was only 0.4 inch during the late afternoon and early evening.

In 1959…northwest winds gusted to 55 mph at Stapleton Airport.

In 1997…the high temperature warmed to only 21 degrees…the record low maximum for the month. The same temperature also occurred on October 30…1991.
