Sunday brings another record day; March 2012 likely to go into record books
Another unseasonably mild day led to another high temperature record being tied on Sunday. As the unseasonably warm weather continues, March 2012 is almost certain to go into the record books on a number of marks.
The temperature at Denver International Airport reached 75 degrees at 4:05pm Sunday afternoon. This tied the record high temperature for the date last set in 1998. This is far and above the normal for the date of 57 degrees.
Here in Thornton we were a bit cooler and reached a high temperature of 72.3 degrees.
The record-tying mark is the fifth time so far this month that the record high temperature was tied or broken. Other days with record highs this month:
- 76 degrees on March 23, which tied the old record of 76 set in 1967
- 76 degrees on March 17, which broke the old record of 75 set in 1974
- 75 degrees on March 16, which broke the old record of 74 set just one year ago in 2011
- 74 degrees on March 13, which tied the old record of 74 set in 2007 and previous years
Officially Denver has recorded only a trace of snow this month and a scant 0.03 inch of precipitation. Given the forecast for the coming week, it is likely the month will end with those totals. If it does, March 2012 will go into the history books as the least snowiest and driest March on record.
In terms of temperatures, Denver’s overall average temperature for the month so far is at 47.0 degrees. That would put the month in a tie for the fourth warmest March on record. However with temperatures expected to remain unseasonably warm through the week, there is a good chance we will climb the ‘top 10’ list even further.

March 25 to March 31 – This Week in Denver Weather History
In stark contrast to the extremely dry and mild month we are experiencing now, March is normally known for its snow. In our look back at this week in Denver weather history we see many significant snow events that have occurred in the past and are much more representative of Denver’s March weather.
From the National Weather Service:
23-25
In 1891…rain changed to snow and totaled 8.8 inches in downtown Denver. Most of the snow fell on the 24th. Winds were light.
In 1964…heavy snowfall of 5.8 inches was measured at Stapleton International Airport. North-northeast winds gusted to 21 mph behind a cold front.
24-25
In 1904…west Bora winds sustained to 40 mph with gusts to 55 mph warmed the temperature to a high of 49 degrees on the 24th. Overnight…a cold front produced 4.5 inches of snow. The high temperature was only 34 degrees on the 25th.
In 1955…a vigorous cold front with winds sustained to 34 mph and gusts to 39 mph briefly reduced the visibility to 2 miles in blowing dust at Stapleton Airport. Post-frontal heavy snowfall totaled 9.5 inches at Stapleton Airport where the maximum snow depth on the ground was 7 inches.
24-26
In 1959…the second major spring storm in less than a week dumped 10 to 20 inches of wet snow across northeastern Colorado. Snowfall totaled 14.3 inches at Stapleton Airport where north winds gusted to 36 mph…causing near-blizzard conditions with visibilities frequently reduced to 1/2 mile in snow and blowing snow. Many travelers were marooned when trains…planes…and buses were unable to make their schedules. Utility lines were again damaged as a result of the storm.
25
In 1874…the wind blowing in gusts from the west-northwest filled the air with dust so dense that only the houses in the immediate neighborhood of the weather station could be recognized. The brisk winds continued through the afternoon.
In 1886…heavy snowfall of 6.5 inches occurred in the city.
In 1896…northwest winds sustained to 58 mph with gusts to 65 mph warmed the temperature to a high of 70 degrees.
In 1911…west winds were sustained to 43 mph. The Chinook winds warmed the temperature to a high of 65 degrees.
In 1925…northwest winds were sustained to 41 mph with gusts to 46 mph.
In 1950…strong Chinook winds gusted to 50 mph at Stapleton Airport.
In 1976…3.4 inches of snow fell at Stapleton International Airport where northeast winds gusted to 46 mph. The strong winds at 20 to 35 mph all day produced a rare “snirt” storm when blowing dust and dirt became mixed with snow and blowing snow reducing the visibility to as low as 1/4 mile at Stapleton International Airport.
In 1984…1 to 4 inches of new snow fell across metro Denver. Icy roads contributed to many accidents. The most hazardous conditions occurred in the foothills west of Denver. Both I-70 and U.S. 40 were closed at the height of the Sunday afternoon ski rush…causing delays of many hours. Snowfall totaled only 1.0 inch at Stapleton International Airport with only a trace on the ground due to melting.
In 1988…high winds in the mountains spread over metro Denver. A wind gust to 75 mph was noted in Boulder where a traffic light was downed. Power outages were reported in Boulder County. Northwest winds to 46 mph were recorded at Stapleton International Airport.

March 18 to March 24 – This Week in Denver Weather History
As our snowiest month, heavy, wet snows are not at all unusual in March. Certainly we see many of those types of events in our look back at this week in Denver weather history. Also notable are the high wind events including one in 1995 that brought down two houses under construction in Thornton.
From the National Weather Service:
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.
17-18
In 1923…4.2 inches of snow fell over downtown Denver. Northwest winds were sustained to 45 mph with gusts to 49 on the 17th. Low temperature of zero degrees on the 18th was the lowest of the month that year.
In 1944…heavy snow fell across metro Denver. The storm started as rain on the 17th…but soon turned to snow. Snowfall amounts totaled 8.5 inches in downtown Denver and 11.0 inches at Stapleton Airport. The highest wind recorded during the storm was 23 mph on the 17th.
In 1961…a major winter storm dumped 10.7 inches of snow at Stapleton Airport. Most of the snow…9.7 inches…fell on the 18th. Winds were light.
In 1994…strong winds buffeted metro Denver. West winds gusted to 51 mph at Stapleton International Airport on the 17th. Other significant wind gusts included 85 mph atop squaw mountain south of Idaho Springs…and 82 mph at Rollinsville southwest of Boulder…both on the 18th.
In 1996…a second storm in less than 3 days dumped heavy snow in the mountains and foothills again…but snowfall amounts across metro Denver ranged from only 2 to 4 inches. The heavy snowfall resulted in several traffic accidents along I-25 and I-70…south and west of Denver respectively. The major accidents involved at least 30 cars and resulted in several minor injuries. The accidents closed both highways for a time. Snowfall totals included 13 inches at Evergreen and 10 inches at conifer. Snowfall totaled only 0.7 inch at the site of the former Stapleton International Airport. At Denver International Airport… North winds gusted to 28 mph on the 17th and 39 mph on the 18th.
17-19
In 1933…rain changed to snow on the evening of the 17th and continued through mid-day of the 19th. Snowfall totaled 5.6 inches with 0.83 inch of precipitation in in the city. North winds were sustained to 38 mph with gusts to 46 mph on the 18th and to 30 mph with gusts to 43 mph on the 19th.
In 2003…one of the worst blizzards since historic records began in 1872 struck metro Denver with a vengeance. Heavy wet snow accumulating to around 3 feet in the city and to more than 7 feet in the foothills brought transportation to a near standstill. North winds sustained to 30 mph with gusts as high as 41 mph produced drifts to 6 feet in the city. The estimated cost of property damage alone…not including large commercial buildings…was 93 million dollars… Making it the costliest snowstorm ever. Mayor Wellington Webb of Denver said…”this is the storm of the century…a backbreaker…a record breaker…a roof breaker.” two people died in Aurora from heart attacks after shoveling the heavy wet snow. The national guard sent 40 soldiers and 20 heavy duty vehicles to rescue stranded travelers along I-70 east of gun club road. The heavy wet snow caused roofs of homes and businesses to collapse. The snow also downed trees…branches…and power lines. Two people were injured when the roofs of their homes collapsed. In Denver alone…at least 258 structures were damaged. In Arvada…a roof collapse at west gate stables killed a horse. Up to 135 thousand people lost power during the storm…and it took several days for power to be restored in some areas. Denver International Airport was closed…stranding about 4000 travelers. The weight of the heavy snow caused a 40-foot gash in a portion of the tent roof…forcing the evacuation of that section of the main terminal building. Avalanches in the mountains and foothills closed many roads…including I-70…stranding hundreds of skiers and travelers. Along I-70…an avalanche released by the Colorado Department of Transportation…blocked the interstate in both directions for several hours. Several residences between Bakerville and Silver Plume were evacuated because of the high avalanche danger. At Eldora Ski Area…270 skiers were stranded when an avalanche closed the main access road. After the storm ended…a military helicopter had to ferry food to the resort until the road could be cleared. The heavy snow trapped thousands of residents in their foothills homes in Jefferson County for several days. Two homes burned to the ground when fire crews could not reach the residences. Some schools remained closed well into the following week. The storm officially dumped 31.8 inches of snow at the site of the former Stapleton International Airport…the most snowfall from a single storm since the all-time record snowfall of 37.5 inches on December 4-5…1913. The storm made March 2003 the snowiest March on record…the 4th snowiest month on record… And the 5th wettest March on record. The 22.9 inches of snow on the 18th into the 19th was the greatest 24 hour snowfall ever recorded in the city during the month of March. The storm was also a drought-buster…breaking 19 consecutive months of below normal precipitation in the city. Snowfall across metro Denver ranged from 2 feet to more than 3 feet. The highest amounts included: 40 inches in Aurora…38 inches in centennial and 6 miles east of Parker…37 inches at Buckley AFB…35 inches in southwest Denver…34 inches in Louisville… 32 inches in Arvada…31 inches in Broomfield and Westminster… And 22.5 inches in Boulder. In the foothills…snowfall ranged from 3 feet to more than 7 feet. Some of the most impressive storm totals included: 87.5 inches atop Fritz Peak and in Rollinsville…83 inches at Cabin Creek…74 inches near Bergen Park…73 inches northwest of Evergreen…72 inches in Coal Creek Canyon…70 inches at Georgetown…63 inches near Jamestown…60 inches near Blackhawk…55 inches at Eldora Ski Area…54 inches 8 miles west of Sedalia…and 46.6 inches at Ken Caryl Ranch. The storm was the result of a very moist…intense slow moving pacific system which tracked across the four corners and into southeastern Colorado…which allowed deep easterly upslope flow to form along the Front Range.
18
In 1883…0.3 inch of snow fell in downtown Denver. This was the only measurable snowfall of the month.
In 1903…rain changed to sleet and then to snow…which became heavy. Post-frontal snowfall totaled 7.0 inches over the city. North winds were sustained to 51 mph with gusts as high as 60 mph.
In 1905…northwest winds were sustained to 42 mph.
In 1914…northeast winds were sustained to 46 mph with gusts to 56 mph behind a strong cold front. Snowfall was 3.4 inches over the city…but most of the snow melted as it fell. The estimated amount of melted snow was 8.1 inches.
In 1920…a terrific windstorm occurred along the eastern foothills. Two deaths were attributed to the storm and some damage occurred. Both Denver and Boulder were affected by the strong winds. West winds were sustained to 51 mph with gusts as high as 66 mph in downtown Denver. The strong winds did considerable damage to property… Wires…plate glass windows…and indirectly loss by fire. The wind caused the death of one young girl by toppling the side of a brick building on her as she was standing on a corner waiting for a car. The wind was also responsible for several severe auto accidents due to blowing debris into the streets and blowing dust and dirt into the eyes of drivers.
In 1954…west winds at sustained speeds of 40 mph and gusts as high as 56 mph produced some blowing dust at Stapleton Airport.
In 1979…heavy snow totaled 4 to 12 inches along the Front Range from Denver north. I-25 was closed for a brief time between Denver and Cheyenne. New snowfall totaled 4.3 inches at Stapleton International Airport where north winds gusted to 29 mph.
In 1998…a major winter storm dumped heavy snow over areas west from I-25 to the continental divide as strong upslope conditions developed. Two to 3 1/2 feet of snow fell in the foothills with 1 to 2 feet reported in west metro Denver. Snowfall totals included: 38 inches at Silver Spruce Ranch…2 miles south of Ward; 35 inches at Aspen Springs; 33 inches near Blackhawk; 30 inches at Eldora; 29 inches in Coal Creek Canyon; 27 inches at Conifer… Chief Hosa…and Nederland; 25 inches at Rollinsville and Gross Reservoir; 21 inches at Evergreen; and 15 to 19 inches at Broomfield…Lakewood…and Table Mesa in Boulder. Elsewhere across metro Denver…snowfall ranged from 8 to 14 inches. Snowfall totaled only 7.9 inches at the site of the former Stapleton International Airport. East winds gusted to 31 mph at Denver International Airport.
