March 14 to March 20 - This week in Denver weather history
Think winter is over? Don’t count on it. A quick look back at this week in Denver weather history illustrates why. Many occurrences of winter-like weather can intrude as we see and we don’t even have to look very far back. It was this week that the March Blizzard of 2003 struck – one of the worst snowstorms in Denver history.
9-19
In 1906…an extended cold and blustery period occurred with light snow totaling 14.4 inches over 11 consecutive days. The greatest amount of snow on a single day was 4.0 inches on the 15th. Only a trace of snow fell on the 12th and 17th. High temperatures were below freezing for the entire period. The coldest were 14 degrees on the 16th and 18 degrees on the 17th. Both readings were record low maximums for the dates. Low temperatures were mostly in the single digits. The coldest were 2 degrees below zero on the 16th and 5 degrees below zero on the 19th. Northeast winds were sustained to 22 mph on the 9th. North winds were sustained to 36 mph on the 10th…32 mph on the 13th…and 22 mph on the 15th.
12-16
In 1880…a protracted cold spell resulted in 8 temperature records being set. Record low temperatures for the date were set when the temperature dipped to 10 degrees below zero on the 13th and 14th…8 degrees below zero on the 12th and 15th…and 4 degrees below zero on the 16th. Daily record low maximum temperatures were set with 11 degrees on the 12th…12 degrees on the 13th…and 19 degrees on the 15th.
13-14
In 1996…a storm system moving across northern Colorado dumped heavy snow in the mountains and foothills and across metro Denver where snowfall ranged from 5 to 10 inches. A foot of new snow was measured at Nederland with 11 inches at Conifer. Snowfall totaled 8.0 inches at the site of the former Stapleton International Airport. Northeast winds gusted to 30 mph at Denver International Airport on the 13th.
13-15
In 1906…snowfall totaled 8.0 inches over downtown Denver.
March 7 to March 13 - This week in Denver weather history
As we talked about in our March weather preview, Denver can see the entire gamut of weather conditions this time of year and our look back at this week in history shows that. There are of course plenty of the famous March snowstorms including big ones in 1992 and 1998. We also see the usual high winds such as was the case in 2000 and even extreme cold as we saw over an extended period in 1906.

At about 7:00 am the worst snow storm of the winter commenced and continued until 10:00 pm…snowing heavily nearly all the time. North winds averaged a sustained speed of 25 mph. About 8 inches of snow fell…but it drifted too much to obtain a direct measurement.
In 1901…northwest winds were sustained to 40 mph with gusts as high as 58 mph. The strong Chinook winds warmed the temperature to a high of 70 degrees.
In 1902…northwest winds were sustained to 45 mph with gusts to 53 mph.

In 1984…a wind gust to 63 mph was recorded at Golden Gate Canyon west of Denver. West winds gusted to 39 mph at Stapleton International Airport.
February 28 to March 6 - This week in Denver weather history
Wild weather is a fact of life in Denver and in Colorado in general. We see that consistently in the history books and this week demonstrates that. As usual we see high wind events and extreme cold. Also notable is that as we enter the month of March, we start to see occurrences of those heavy, wet spring snows that can wreak havoc.

NASA's Terra satellite captured amazing images of snow across the Rocky Mountain region. See below for a larger picture covering a much larger area. (NASA)
Winter weather arrived over the Rocky Mountain region this past weekend covered the entire area in a blanket of white. NASA’s Terra satellite captured amazing images of the snow cover across parts of 10 states.
From Yellowstone National Park in Wyoming across to Mt. Rushmore in South Dakota, Salt Lake City to Denver and the Grand Canyon through New Mexico to Oklahoma the images are amazing. Few areas across the thousands of square miles are spared snow in the images.
NASA’s Terra satellite and its Moderate Resolution Imaging Spectroradiometer (MODIS) routinely capture stunning images.
Snow cover stretched from South Dakota’s Mt. Rushmore to Arizona’s Grand Canyon in late February 2010, after snowstorms blanketed the Rocky Mountains. Mostly cloud-free skies allowed the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite this largely unobstructed view of the western continental United States on February 23, 2010.
From northern New Mexico, the Rocky Mountains stretch northward through Colorado and Wyoming. Along the eastern face of this mountain range, rugged terrain gives way to prairie, including the flat topography of eastern Wyoming and Colorado. Mountains extend far westward, however, with snow cover accentuating mountain peaks all the way to Salt Lake City. The snow-free Grand Canyon snakes a serpentine path in the southwest, but the land surrounding that park is snow covered, as is much of northern Arizona and New Mexico.

February 21 to February 27 - This week in Denver weather history
Snow and wind dominate our look back at this week in Denver weather history. Just last year, high winds on the Boulder Turnpike blew a trailer into oncoming traffic damaging two cars and injuring one driver. 40 years ago, a protracted cold spell resulted in seven consecutive days with low temperatures dropping to zero or below. Those are just two of the many events – see more below.
19-21
In 1971…heavy snowfall totaled 9.0 inches at Stapleton International Airport where north winds gusted to only 16 mph. Most of the snow occurred on the 19th and 20th. The 24 hour snowfall of 8.2 inches was the greatest in February since 1953.
20-21
In 1997…heavy snow fell in the foothills. Snowfall totals included: 16 inches at Eldora Ski Area; 15 inches at South Turkey Creek; 14 inches at Conifer and Morrison; and 11 inches at Blackhawk…Evergreen…and Intercanyon. Only 1.0 inch of snow fell at the site of the former Stapleton International Airport. Northeast winds gusted to 32 mph at Denver International Airport on the 20th.
21
In 1901…northwest winds sustained to 43 mph with gusts to 46 mph warmed the temperature to a high of 55 degrees.
In 1935…strong west to northwest winds sustained to 30 mph with gusts to 34 mph produced considerable blowing dust. The Chinook winds warmed the temperature to a high of 60 degrees.
In 1967…west winds gusting to 53 mph produced some blowing dust at Stapleton International Airport. Winds were strong and gusty all day.
In 1988…high winds were reported along the foothills with 90 mph in east Boulder where the winds knocked out a few street and traffic lights. The strong winds whipped a grass and timber fire in Boulder canyon. The fire threatened some homes for a time…but was extinguished before causing any significant property damage. West winds gusting to 35 mph at Stapleton International Airport warmed the temperature to a high of 63 degrees.
21-22
In 1909…a major storm dumped 12.9 inches of heavy snowfall over the city. North winds were sustained to 37 mph on the 22nd. Temperatures during the storm hovered in the 20’s.
22
In 1893…northwest winds were sustained to 36 mph with gusts to 50 mph.
In 1900…northwest winds sustained to 40 mph with gusts to 45 mph warmed the temperature to a high of 61 degrees.
In 1910…a cold front caused a remarkably sharp drop in temperature from 43 degrees at 3:00 am to only 3 degrees at 8:30 am. These were the high and low temperatures for the day. Early west winds switched to northeast behind the front.
In 1927…west winds were sustained to 42 mph with a measured maximum velocity to 60 mph.
In 1954…strong and gusty west winds persisted throughout the day. The highest wind gust recorded at Stapleton Airport was 58 mph.
In 1960…snowfall totaled 5.9 inches…producing near-blizzard conditions in snow and blowing snow at Stapleton Airport where northeast wind gusts to 40 mph reduced visibility to 1/2 mile.
In 1986…high winds occurred in the foothills. Wind gusts of 65 to 70 mph were reported at Golden Gate Canyon…and a peak gust of 83 mph was recorded at Echo Lake. Northwest winds gusted to only 29 mph at Stapleton International Airport.
In 1988…a wind gust to 83 mph was recorded in Boulder with 80 mph clocked at Rollinsville. Northwest winds gusted to 45 mph at Stapleton International Airport.
In 1996…wind gusts to 63 mph were reported in western Elbert County. Southwest winds gusted to 45 mph at Denver International Airport.
In 1999…strong post-frontal…Bora winds developed over the foothills and spread over the northeast plains. Peak wind gusts included: 87 mph at Golden Gate Canyon; 84 mph at Wondervu; 80 mph at the National Center for Atmospheric Research mesa lab; 75 mph at the Rocky Flats Environmental Test Facility; 74 mph at Jefferson County Airport near Broomfield; 72 mph at the Gamow Tower on the University of Colorado campus in Boulder; and 60 mph at Bennett. West to northwest winds gusted to 44 mph at Denver International Airport.
In 2000…thunder was heard across much of metro Denver. Thunderstorms over southwest metro Denver produced 1/4 to 1/2 inch diameter hail at Pinehurst Country Club. A thunderstorm at Denver International Airport produced wind gusts to 34 mph. This was only the 6th time since 1891 that thunder had been reported in February.
After receiving a shot of snow last night, Thornton can expect continued chances of snow throughout the weekend. Temperatures will continue to be well below seasonal normals throughout.
Most areas of Denver received a couple inches of snow last night blanketing the Mile High City in white. Here in Thornton, as we forecast yesterday, we received 2.2 inches. With this latest round, it is likely that Denver will exceed the average amount of snow we receive in February – 6.3 inches. We will know for sure when the National Weather Service releases their official measurement from DIA later this morning.
For Friday, overcast and cold will be the keywords. High temperatures today will only reach 34 degrees and there is a slight chance of an isolated snow flurry here and there. No daytime accumulation of snow is expected. Overnight tonight after 11:00pm look for the chance of snow to increase with a half inch or so being possible.
Saturday the cold continues and the snow chances increase. Temperatures will be right around the freezing mark ensuring that if you venture outside, you will be bundled up. There may be a morning snow flurry or two with the chances increasing after 11:00am or so at which point we could see a couple inches between then and the evening.
A chance for snow continues throughout Saturday night and early Sunday morning. Total accumulations will be much like what we received last night. Look for between 2 and 4 inches in the metro area. The mountains and foothills will receive between 5 and 10 inches and areas closer to the Wyoming border between 3 and 6 inches.
Sunday brings even colder temperatures with forecast highs for Thornton only around 29 degrees. Snow will slowly be coming to an end with a lingering flurry or two possible throughout the day.
The weather forecast for Monday going forward is still a bit muddled. A slight chance of snow continues on Monday before things should warm up and clear out on Tuesday. Wednesday and Thursday however the chance for snow returns.

Just some of the artists performing ‘We Are the World: 25 for Haiti’. Watch the video below.
One month after a devastating magnitude earthquake struck Haiti claiming the lives of more than 230,000 a band of musicians released a new song and video to aid relief efforts. Premiering at the 2010 Winter Olympics in Vancouver, ‘We Are the World 25 for Haiti’ is a remake of the song originally recorded 25 years ago to aid famine relief in Ethiopia.
The song was originally written by Michael Jackson and Lionel Richie and performed by music artists of the time. According to USA for Africa, more than $63 million was raised as the song went on to become the biggest selling single of all time.
Bringing together more than 80 contemporary artists from across the music industry and all genres, the new version seeks to repeat that success on the 25th anniversary of the original. A new non-profit organization named the We Are the World Foundation will collect and distribute funds collected via cash donations and the purchase of the song and the video.
The video and song are reminiscent of the original showing the various artists singing in unison with many performing brief solos.
Introduced by Jamie Foxx, the video intersperses footage of the devastation on the ground in Haiti with that of the artists performing in a studio. A veritable who’s who in the music industry takes part – see the complete list below the video.

Last year's "Summer of Storms" should serve as a reminder of the severe weather threat in Denver.
Remember last year’s “Summer of Storms” that saw a seemingly endless parade of hail, funnel clouds and tornadoes visit the Front Range? The severe weather threat in Colorado is real and it can turn deadly in an instant.
Education is key to knowing how to protect you and your family. Whether you want to be an official storm spotter or maybe just want to learn more about severe weather, storm spotter training can provide you an incredible opportunity to learn.
The storm spotter program is a nationwide program with more than 280,000 trained spotters. These volunteers report weather hazards to their local National Weather Service office providing vital information when severe strikes. Data from spotters include severe wind, rain, snow measurements, thunderstorms and hail and of course tornadoes.
Storm spotters are part of the ranks of citizens who form the Nation’s first line of defense against severe weather. There can be no finer reward than to know that their efforts have given communities the precious gift of time–seconds and minutes that can help save lives.
By completing one of these training classes you can become an official storm spotter. When severe weather strikes, you can report it by calling a special toll free number or submit your report via the National Weather Service’s website.
These are great sessions for anyone wanting to learn more about the severe weather we experience in Colorado, whether you want to be an official spotter or not. All training is free. Topics include:
Below are the dates, times and locations announced thus far. There is one this coming weekend in north Denver, two in Westminster in March and one in Commerce City in April – all are great opportunities for Thornton residents. Click here to go to the NWS site for the latest.

February 7 to February 13 - This week in Denver weather history
You can tell how eventful a week in Denver weather history is by the length of these articles and this one is a long one for sure. In history we have seen Arctic cold, spring-like warmth, major snowstorms and blizzards and hurricane force winds. There is even a rare thunderstorm that dropped a bit of hail.
30-7
In 1985…a cold front on the 29th produced a protracted cold spell as arctic air remained entrenched across metro Denver. While the only daily temperature record set was a low maximum reading of 2 degrees on February 3rd…minimum temperatures plunged well below zero on 9 consecutive days. The coldest readings were 15 degrees below zero on January 31st and 14 degrees below zero on February 5th.
31-8
In 1963…warm weather that began with the strong Chinook winds on the 31st and 1st continued through the 8th. Maximum temperatures through the period ranged from 52 degrees on the 2nd to 76 degrees on the 5th…which was a new record high for that date.
31-12
In 1899…a protracted cold spell lasted almost two weeks. Low temperatures plunged below zero on all days but February 9th with a reading of 6 degrees. The coldest low temperature of 22 degrees below zero on February 6th was a record low for the date. Low temperatures of 20 degrees below zero occurred on both February 11th and 12th… But only the 11th remains as the record minimum for the date. High temperature of only 5 degrees below zero on February 11th was a record low maximum for the date. High temperatures climbed to only zero degrees on both February 2nd and 3rd…but were not records. Intermittent light snow or flurries fell during the period. The most snowfall…2.0 inches…occurred on February 2nd.
1-9
In 1883…a protracted cold period occurred when low temperatures dipped below zero for 9 consecutive days. Low temperatures ranged from 22 degrees below zero on the 4th to 2 degrees below zero on the 1st and 6th. High temperatures ranged from 10 below zero on the 3rd to 23 on the 9th. Several temperature records were set that still stand today. Record lows of 18 below and 22 below zero occurred on the 3rd and 4th. Record low maximum readings of 2 below and 10 below zero occurred on the 2nd and 3rd. The high of only 10 below zero on the 3rd is the coldest maximum temperature ever recorded in Denver.
5-11
In 1978…the 5th marked the start of a record 7 consecutive days of dense fog at Stapleton International Airport. The heavy fog reduced the visibility to 1/4 mile or less for a period of time on each of these days. Light snow and/or freezing drizzle occurred on most days. Fog reducing visibility to less than 7 miles was recorded at Stapleton International Airport on 11 consecutive days through the 15th. During the period 5-14…the cold thick fog deposited heavy rime ice up to 5 inches thick on power lines and poles over a wide area of eastern Colorado…causing a major electrical power outage disaster.
After receiving a shot of snow last night, Thornton can expect continued chances of snow throughout the weekend. Temperatures will continue to be well below seasonal normals throughout.
