North winds gusting to 43 mph whipped nearly 10 inches of snow in Denver into 3-foot drifts and snarled traffic on the morning of the 4th. Snowfall totaled 9.8 inches at Stapleton International Airport.
In 1989…a storm dumped 2 to 6 inches of snow across metro Denver. The snow caused 2-hour air traffic delays at Stapleton International Airport where 3.0 inches of snow fell and north winds gusted to 23 mph on the 3rd. There were many traffic accidents across metro Denver. I-70 was closed east of Denver for a time on the 3rd.
In 1991…high winds raked the eastern foothills. Wind gusts of 60 to 90 mph were common with 119 mph recorded at Wondervu southwest of Boulder…106 mph on Shanahan Ridge and 92 mph at Table Mesa…both in southwest Boulder. Several trees were uprooted and traffic signs and lights blown over. Flying debris caused damage to homes… Buildings…and cars. In Boulder…a stop sign was blown onto a car. There were no reports of injuries. Southwest winds gusting as high as 48 mph briefly reduced the prevailing visibility to as low as 1/16th mile in blowing dust at Stapleton International Airport on the 4th.
Icy roads Saturday morning led to a massive 104 car pileup on Interstate 25 through central Denver killing one person and injuring 30.
The chain reaction accident began just before 11:00 a.m. near University and Downing on the northbound side of the interstate. Cars, unable to stop on the ice and snow covered highway, began piling up.
One woman was killed in the accident. Her name is currently being withheld. The woman’s vehicle struck the back of a semitrailer, peeling the roof back as it lodged under the trailer.
Thirty people were injured and transported to area hospitals including Denver Health, St. Anthony’s and Swedish Medical Center. Among the injured were adults and children.
The past two months have brought periods of extreme cold but not a lot of snow to Denver. March however is our snowiest month and may bring a turnaround in those numbers. It also typically brings much warmer temperatures.
March is historically Denver’s snowiest month and brings about 20% of our annual snowfall. Heavy, wet spring snow storms can oftentimes bring the entire month’s snowfall total in one monstrous snow.
We also start the transition to spring and severe weather season and the month typically brings our first thunderstorms of the year. Temperatures climb throughout the month and by the end our average daytime highs are near 60 degrees.
February 23 to March 1: This Week in Denver Weather History
Hurricane force winds, heavy snowfall, sub-zero temperatures and even a dust storm highlight some of the events from this week in Denver weather history.
From the National Weather Service:
22-23
In 1985…a snowstorm struck the eastern foothills with 8 to 15 inches of new snow. Three to 7 inches of new snow fell across metro Denver and parts of I-70 were closed at times. Snowfall totaled only 3.3 inches at Stapleton International Airport where northeast wind gusts to 29 mph were recorded.
In 1992…a snow storm dumped heavy snow in the Front Range foothills. Conifer received 12 inches of new snow with 7.5 inches at Aspen Springs. Snow only dusted the plains and metro Denver…but winds were strong with a gust to 43 mph from the north at Stapleton International Airport where snowfall totaled only 0.3 inch. This was the only measurable snowfall of the month…equaling the record for the least snowiest February first set in 1970. Rare thunder for February accompanied the snow during the early morning hours of the 23rd.
In 1999…strong Chinook winds developed on a very localized scale overnight in and near the foothills of northern Jefferson and southern Boulder counties. Peak wind reports included: 82 mph at the Rocky Flats Environmental Test Facility…80 mph at the National Center for Atmospheric Research mesa lab in Boulder…77 mph near Nederland…and 75 mph atop the Gamow Tower on the University of Colorado campus in Boulder.
In 2012…a strong upper level jet stream produced high winds along the Front Range. In Boulder…the strong winds snapped power poles and toppled trees. As a result…about 7 thousand Xcel Energy customers were without power for several hours. The high winds overturned a tractor-trailer on foothills highway overpass…north of Valmont road. The driver suffered minor injuries. A parked car was totaled when it was crushed by a fallen tree near the University of Boulder. The strong winds were also responsible for two Boulder County wildfires which consumed a total of 65 acres. Colorado department of transportation officials closed U.S. 36 at McCaslin Boulevard in both directions after the wind caused damage to the pedestrian overpass. Metal siding from the overpass fell into highway; fortunately there were no injuries. In total…electrical outages affected 46 thousand customers along the Front Range. Damage to roofs…siding… Garage doors and fences was also reported. Peak wind gusts included: 93 mph near Lyons; 88 mph at NCAR Mesa Lab; 85 mph…2 miles southwest of Rocky Flats; 82 mph…5 miles northwest of Boulder; 81 mph…2 miles north of Longmont…4 miles east-northeast of Nederland…the National Wind Technology Center and near Wondervu; 80 mph at the junction of highways 72 and 93; 79 mph at the Boulder Municipal Airport; 78 mph…6 miles northwest of Boulder; 77 mph at Rocky Mountain Municipal Airport; 76 mph atop Berthoud Pass; 75 mph near Aspen Springs; 70 mph at Longmont Municipal Airport; 64 mph at Erie Municipal Airport. At Denver International Airport…peak wind gusts of 53 mph on the 22nd and 55 mph on the 23rd were observed.
22-29
In 1960…heavy snowfall of 6.1 inches at Stapleton Airport on the 22nd and 23rd marked the beginning of a protracted cold spell which lasted until the end of the month. The cloudy… Cold weather was accompanied by occasional light snow or flurries and fog. New record low temperatures for the dates were set on the 24th thru the 29th with the lowest temperature of 11 degrees below zero on the 28th. The seven consecutive days of low temperatures of zero or below had been exceeded in duration only 4 times previously. New low maximum temperatures for the dates were set on the 23rd… 24th…and the 26th thru the 29th with the lowest maximum temperature of 8 degrees recorded on the 26th.
23
In 1904…west winds sustained to 42 mph with gusts as high as 60 mph warmed the temperature to a high of 63 degrees.
In 1907…a thunderstorm…relatively rare in February…was observed over the city. The chance of occurrence is around once every ten years.
In 1977…while 60 to 100 mph winds produced a huge dust storm over much of eastern Colorado…only an experimental windmill at the Rocky Flats nuclear plant was destroyed in the Denver area. Winds at Rocky Flats were clocked to 90 mph. Northwest winds gusted to 46 mph at Stapleton International Airport.
In 1986…wind gusts to 79 mph were clocked at Echo Lake in the foothills west of Denver.
In 1992…a rare February thunderstorm occurred. This was only the 5th time since 1891 that thunder has been heard in February.
In 1994…periodic high winds occurred over the higher elevations of the Front Range eastern foothills. The strongest wind gusts reached 87 mph atop Squaw Mountain near Idaho Springs. Southwest winds gusted to only 25 mph at Stapleton International Airport.
In 1996…high winds gusting as high as 76 mph were reported along the Front Range foothills and adjacent urban corridor. Wind gusts to 70 mph were reported atop Table Mesa near Boulder and to 63 mph in Broomfield. West winds gusted to 38 mph at Denver International Airport.
In 2012…bands of moderate to heavy snow…associated with a strong upper level jet…formed over the southern Front Range foothills…Palmer Divide and southern Denver suburbs. Storm totals included: 10 inches…2 miles west-northwest of Highlands Ranch and Kiowa; 9.5 inches near Castle Rock and Littleton; 8 inches at Aspen Springs and Marston Reservoir; 7.5 inches at Evergreen and Louviers; 7 inches…5 miles south-southwest of Arapahoe Park; with 4 to 6 inches elsewhere. Officially…Denver International Airport observed 1.9 inches of snowfall.
23-24
In 1935…northwest winds sustained to 37 mph with gusts as high as 47 mph produced considerable blowing dust behind a cold front on the 23rd. The dust was dampened by 7.0 inches of snowfall over downtown Denver from the late evening of the 23rd through the evening of the 24th.
In 1997…heavy snow fell in the foothills. Snowfall totals included 8 inches at sunshine canyon northwest of Boulder… And 6 inches at Morrison. Snowfall totaled only 2.4 inches at the site of the former Stapleton International Airport. East winds gusted to only 22 mph at Denver International Airport on the 23rd.
23-25
In 1912…a severe winter storm dumped 14.2 inches of snowfall over downtown Denver. Snow fell continuously from 9:40 am on the 23rd until 9:15 pm on the 25th with most of the snow… 9.2 inches…on the 24th. Temperatures were mostly in the 20’s. Northeast winds were sustained to 20 mph on the 24th.
With snowpack lagging and spring set to arrive, hopes were high that March could bring some relief to Colorado’s parched landscape and Mother Nature did oblige. March 2013 brought above average snowfall and cooler than normal temperatures.
The month started out with near normal temperatures but the first in a series of disturbances throughout the month arrived on the 4th. A couple of inches was delivered to the area on the date which was followed by a few days of mild weather.
The warmth did not last as another storm system which began a repeating pattern across the month with mild temperatures followed by periods of cold and snow.
Thornton’s overall average temperature for the month came in at 38.3 degrees. At Denver’s official weather station at Denver International Airport the month averaged 37.7 degrees. Both locations’ average temperatures were below the March historical average (1981 to 2010) of 40.4 degrees.
We recorded 25 days with low temperatures dropping below the freezing mark. Three days saw high temperatures fail to climb above 32 degrees.
Our warmest temperature during March 2013 was a reading of 78.6 degrees on the 15th. The coldest reading was on the 24th when the mercury dropped to a bone-chilling 2 degrees. Out at DIA, the warmest reading was 76 degrees on the 15th and the coldest was 2 degrees on the 25th.
In terms of precipitation, Thornton saw 1.45 inches in the rain bucket, almost all from snow. Denver’s numbers were near identical at 1.47 inches. Both were well above the March average of 0.92 inch.
Snowfall was the big story for the month as Thornton recorded 20.2 inches of the white stuff. Out at DIA the Mile High City saw even more as it measured 23.5 inches. March historically averages 10.7 inches so we were well above normal while the month’s reputation as our snowiest month of the year held true.
The month did come very close to making the list of ‘top 10 snowiest Marches.’ The number 10 spot on that list came in 1981 when 24.0 inches was recorded.
Despite the cold and snow, only one weather record was set during the month. The 11.6 inches of snow recorded at DIA from the 22nd to the 23rd set a two-day snowfall total record for the date, besting the previous mark of 8.0 inches set in 2010.
