This Week In Denver Weather History

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.

25-26

In 1899…a major storm dumped 13.1 inches of heavy snow over downtown Denver. Rain changed to snow around mid- morning on the 25th. Snowfall became heavy and continued until late evening on the 26th. North to northeast winds gusted to 30 mph on both days. The cold air mass plunged temperatures from a high of 55 degrees on the 25th to a low of 8 degrees on the 26th.

In 1995…a potent early spring storm produced heavy snow in the mountains…but skipped over metro Denver…before producing blizzard conditions and 6-foot drifts over eastern Colorado…causing the closure of I-70 and other highways. Only 0.7 inch of snow fell at the site of the former Stapleton International Airport. North winds gusted to 40 mph at Denver International Airport on the 25th.

In 2001…a persistent band of moderate to heavy snow showers with a few embedded thunderstorms formed in the foothills around Estes Park and spread to the southeast across Boulder and Denver and on the plains to the east of Denver. Thunder and snow was reported at Jefferson County…Centennial…and Denver International Airports during the evening of the 25th.

26

In 1910…west winds were sustained to 42 mph. A snow shower produced a trace of snow.

In 1935…a severe dust storm swept across the city. The dense dust blew in on a gale from the east-northeast. The dust “bank” was first visible on the northeastern horizon at about 2:00 pm. It advanced toward the city as a rolling…swirling…yellowish-to smoke-black cloud. At 2:06 pm…the cloud of dust enveloped the station. Before the storm the visibility was unlimited. At 2:08 pm…the visibility was reduced to 1/8th mile. By 2:25 pm…the visibility was increasing and was above 1000 feet at 3:10 pm. Thereafter…the sun appeared as a dim “ball of fire” at times. The dust was partially gone at 8:30 pm. During the storm…northeast winds were sustained to 32 mph with gusts as high as 35 mph.

In 1971…the highest recorded temperature in March…84 degrees…occurred. This was the highest temperature recorded so early in the season. Previously…84 degrees had not been reached until April 21st. The temperature also exceeded the previous daily record of 75 degrees set in 1960. Strong northwest Chinook winds gusting to 37 mph at Stapleton International Airport were partially responsible for causing the extremely warm weather so early in the season.

In 1985…strong winds occurred along the foothills. A wind gust to 76 mph was recorded in Boulder. A dust storm produced by the strong winds caused a 35-car pileup on I-25 north of Denver. In Denver…the high winds blew out windows in a few downtown buildings. West winds gusted to 52 mph at Stapleton International Airport.

In 1993…strong winds from high based thunderstorms blew a roof off an Englewood business onto several parked cars.

At Stapleton International Airport… Where no thunder was heard…a microburst wind gust to 55 mph briefly reduced the visibility to zero in blowing dust.

In 1994…heavy snow fell in the foothills west of Denver and over the palmer divide to the south of metro Denver. Snowfall totaled 11 inches at both the Eldora Ski Area and at Idaho Springs. Only 1.3 inches of snowfall were measured at Stapleton International Airport where north winds gusted to 28 mph.

High temperature of only 15 degrees on the 27th was a record low maximum for the date. Low temperature of 2 degrees below zero on the 27th was not a record.

In 1975…a major pre-Easter blizzard…the worst since the vicious storm of 1949…battered northeastern Colorado and left livestock losses in millions of dollars…but metro Denver escaped the main brunt of the storm and received only 5.0 inches of snowfall.
