Thornton’s December preview: Hoping for snow

Thus far the snow season has been far less than kind to Colorado.  Snow totals are running well below normal from the plains to the Rockies.

December may bring some hope as the month is our third snowiest. The month brings with it the official start to winter and the month usually brings with it our first real taste of Arctic temperatures.

Precipitation can be hit or miss with monster snowstorms possible but we have also seen starkly dry years.

Current long range forecasts indicate we may very well see continued dry and warm weather.

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.

November 2012 Thornton weather recap: Warmer, drier than normal

Thornton's November 2012 weather recapThe two key weather related words to describe the Denver area’s November 2012 of ‘dry’ and ‘warm’ hardly come as a surprise.  The month saw unseasonably mild temperatures and little in the way of precipitation despite it historically being our second snowiest month.

Above normal temperatures dominated the month from the start with eight out of the first nine days recording readings warmer than average.  Colder weather then arrived and brought Thornton and the Mile High City its first snowfall of the season.  The cooler temperatures did not last long and warmer weather returned for the majority of the balance of November.

Thornton saw an overall average temperature of 41.1 degrees.  Highs averaged 57.3 degrees down to an average low of 26.9 degrees.

Denver’s official average temperature of 43.5 degrees was slightly warmer than Thornton’s.  While mild, it was not warm enough to make it into the list of ‘top 10’ warmest Novembers on record.

Here in Thornton our warmest temperature of the month occurred on the 7th when the mercury climbed to 74.6 degrees.  The coldest morning occurred on Veterans Day (November 11) when temperatures dropped to a chilly 15.0 degrees.

Precipitation was lacking throughout the month as Thornton recorded a scant 0.37 inch in the bucket.  Denver officially recorded less at 0.27 inches.  Both measurements were below the average of 0.61 inch for November.

The season’s first snowfall occurred on the 10th of the month with 1.5 inches being recorded in Thornton.  Out at DIA they recorded slightly more at 1.7 inches.  On average Denver sees 8.7 inches of snow during November so we were well below average.

Saturday's sunset was stunning as seen in this photo from Thornton. (Steve Hill)

Colorado is home to some of the most beautiful sunsets and sunrises as more often than not, Mother Nature begins and ends the day with a light show of her own.  Yesterday a mountain wave cloud sat over the Front Range and when the day came to close, it was lit fiery red.

We posted a photo from one of our readers, Steve Hill, yesterday.  Today we came across a video posted to Facebook taken by Centennial resident Sean Crowley of the evening’s event that is simply too good not to share – check it out below.  The colors coupled with the rolling movement of the clouds are captivating.

Also, just a friendly reminder that we are raising money to upgrade our webcams to HD, something that would allow us to capture such stunning events and share them with the community.

Veterans Day: A message from ThorntonWeather.com about our nation’s heroes

Veterans Day 2012November 11th is one of two holidays in the United States that we have set aside to ensure that those that have served and sacrificed for this nation are never forgotten.  We are asked to take the time to say a simple ‘thank you’ to these men and women while not always fully comprehending their contributions.

For 237 years men and women have stepped forward and answered the nation’s call to arms.

From the bloody birth of our nation to a devastating war that would pit brother against brother and threaten to tear the country apart, veterans have served.

From a time when a cowardly attack at Pearl Harbor woke a sleeping giant to another, similar event 60 years later on our shores in New York, Pennsylvania and Washington DC, veterans have answered the call.

Not all have served in combat but they have served with distinction and honor.  These men and women are the real “1%” – the ones who have stood up for something greater than themselves.

They chose not to whine or cry about the hand life dealt them or their own failures and inability but instead saw an opportunity.  Our veterans did not point their fingers and blame others.  They instead donned the nation’s uniforms proudly and bettered themselves, served their fellow man and defended freedom across the globe.

The legacy of these men and women is seen not only in the peoples they liberate and protect but also close to home.

In my own family, my dad served in Guam in the Air Force.  My brother and I served in the Navy and I did a tour in the Persian Gulf.  At this very moment my nephew is ‘boots on the ground’ in Afghanistan.

My family is not unique however.  Many have seen grandfathers, fathers and sons serve our nation as the values they hold dear are passed on to subsequent generations.

The lessons of honor, courage, commitment and love of God and country are part of the very fiber that makes up our veterans and have formed the backbone of this great nation.  Whether they served at home or abroad, behind a desk or in a jungle or desert, veterans have made a difference and for that we are grateful.

Rudyard Kipling famously wrote:

God and the Soldier, we adore,
In time of danger, not before.
The danger passed and all things righted,
God is forgotten and the Soldier slighted.

Today we honor our soldiers, sailors, Marines, airmen and Coast Guardsmen and we thank them for their service.  It is our solemn promise to them that they will not be forgotten and they will not be slighted.  That is the least we can do.

Thank you to our veterans.

November 11 to November 17 - This Week in Denver Weather History

Two conditions seem to dominate Denver weather this time of year – snow and wind. Both of those make numerous appearances in our look back at this week in Denver weather history.

From the National Weather Service:

10-11

In 1911…a strong cold front produced snow and a cold wave. The temperature dropped 68 degrees from a high of 66 degrees at 12:40 pm on the 10th to a low of 2 degrees below zero at 7:15 am on the 11th. The low temperature of 23 degrees at midnight on the 10th was also the high temperature on the 11th. Northeast winds were sustained to 42 mph with gusts to 51 mph. Snowfall was only 2.5 inches.

In 1982…up to 4 inches of snow fell over the higher terrain between Denver and Colorado springs. Winds gusted to 50 mph along the foothills. Rainfall totaled 0.27 inch with only 0.1 inch of snow on the 11th at Stapleton International Airport where north winds gusted to 39 mph. Dense fog with visibilities as low as zero persisted all day on the 10th.

11

In 1901…a trace of rain fell in the morning…and a trace of snow fell in the afternoon. This was the only snowfall and precipitation for the month…ranking it the driest November on record…along with November of 1899 and 1949. The month also ranks as the second least snowiest November…along with Novembers in other years.

In 1903…northwest winds sustained to 45 mph with gusts to 56 mph warmed the temperature to a high of 56 degrees.

In 1912…rain changed to snow…which became heavy…and totaled 6.5 inches over downtown Denver. Precipitation was 1.02 inches…the greatest calendar day precipitation ever recorded in November. Northeast winds were sustained to 27 mph with gusts to 29 mph.

In 1919…light snow fell from an apparent clear sky during the early afternoon. The first snow was observed at about 12:40 pm and continued at least 30 minutes before clouds could be seen forming…followed by the sky becoming totally cloudy. During this time the temperature fell from 50 degrees at noon to only 18 degrees at 100 pm and plunged to 6 degrees at 5:45 pm. A low temperature of 2 degrees was recorded overnight. Northeast winds were sustained to 33 mph with gusts to 36 mph between noon and 1:00 pm behind an apparent arctic cold front. Snowfall was only 0.1 inch.

In 1949…north winds gusted to 50 mph at Stapleton Airport. A trace of rain fell. Another trace of rain on the 15th was the only precipitation of the month…making the month one of the driest Novembers on record and the least snowiest with no snow. This was the first November since 1882 without snow.

In 1959…strong northwest winds struck Boulder and the foothills causing some damage. West winds gusted to 37 mph at Stapleton Airport.

In 1995…strong downslope winds gusting to 84 mph blew out a few car windows in Boulder County. Winds gusted to 69 mph at Golden…Lakewood…and Table Mesa in Boulder. West-northwest winds gusted to 43 mph at Denver International Airport.

In 2000…heavy snow occurred in the foothills southwest of Denver and over Monument Ridge south of Denver. Snowfall totals included: 6.5 inches near Parker… 6 inches near Bergen Park…5 inches at Genesee and near Sedalia…and 4 inches at Coal Creek Canyon and St. Mary’s glacier. Snowfall totaled 1.6 inches at the site of the former Stapleton International Airport.

In 2003…strong downslope winds developed along the Front Range. Peak wind reports included 91 mph atop Blue Mountain near Wondervu and 75 mph in Boulder. Damaging winds downed power lines in Boulder County. North of Golden…a semi-truck was blown over by the winds near the intersection of State Highways 72 and 93 atop Rocky Flats. At the same location…blowing rocks shattered several car windows at an RTD Park and Ride. West winds gusted to 40 mph at Denver International Airport.

Will the weather determine the next president?

Weather – The true determining factor of who will be president?
Weather – The true determining factor of who will be president?

We oftentimes hear about how weather can affect voter turnout but is there truly a link?  If there is, who does it benefit – Republicans or Democrats?  Studies seem to indicate that what might be thought of as an urban myth is indeed true.

In 2005, political science researchers Brad Gomez, Thomas Hansford and George Krause completed the first comprehensive study on the correlation between weather and voter turnout.  Their paper, “The Republicans Should Pray for Rain:  Weather, Turnout, and Voting in U.S. Presidential Elections” confirmed the conventional wisdom that weather does affect voter turnout, bad weather benefits Republicans and most interestingly, two presidential elections in the last 60 years may have had different results had the weather been different.

Looking back at presidential elections from 1948 to 2008, the study takes into account the weather in 3,000 U.S. counties.  They in turn looked at key areas of the nation and how weather, good and bad, affected voter turnout.  In the end, the study determined that precipitation is the key weather condition to affect voter turnout.

November 4 to November 10 - This Week in Denver Weather History

Our look back at this week in Denver weather history is shorter than what we often see which shows the normally quiet weather we see in November. However there are still significant weather events in the past, most of which involved heavy snow and powerful winds.

From the National Weather Service:

2-5

In 1946…a major snow storm dumped 30.4 inches of heavy snowfall downtown and 31.0 inches at Stapleton Airport. 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.

3-4

In Denver…winds averaged 40 mph with gusts to 70 mph. Some damage was reported to utility lines…signs…and vehicles. Northeast winds were sustained to 30 mph at Stapleton Airport.

4-5

October 2012 Thornton weather recap: A relatively calm month

ThorntonWeather.com October 2012 Weather Recap
A late month snow in October 2012 covered the nearby Flatirons in a blanket of white. (ThorntonWeather.com)

The Colorado Front Range saw a relatively calm month in October 2012 but also a change in the hot and dry pattern we had been stuck in.  Temperatures were below normal for the first time in months and above average precipitation was recorded.

October 2012 started out with an average day on the first but the 2nd and 3rd of the month brought temperatures above 80 degrees.

That warm weather didn’t last long however as a cold front moved in on the 4th and brought much cooler temperatures.  Denver officially recorded its first snow of the season on the 5th (0.4 inch at DIA) however Thornton missed out and did not record any with that system.

Temperatures remained cooler than normal for most of the first half of the month.  On the 13th we received a light dose of rain (0.13 inch in Thornton) while Denver recorded a more generous 0.55 inch.

A calm period followed through the third week of the month.  Temperatures were generally mild though and above normal.

Big changes arrived on the 24th as a large upper level trough and cold front moved in.  Thornton recorded a combined total of 5.7 inches of snow on the 25th and 26th.  Denver recorded 5.1 inches at the airport during the period.
