The snow fell on a weekend…so closures and other disruptions were minimal. The public reported thunder in Arvada…Wheat Ridge…and Boulder on the evening of the 27th. A thunderstorm produced snow pellets at Stapleton International Airport during the early morning hours of the 28th. This was the first thunderstorm in the city during January since 1932.

In 2011…a frigid arctic airmass settled into Front Range urban corridor. At Denver International Airport… Overnight low temperatures…from the 1st to the 3rd… Were 13 below zero…17 below zero and zero respectively. The icy temperatures caused pipes to crack and burst following the freeze. In Loveland…firefighters responded to more than a dozen water pipe breaks…most in fire sprinkler systems at businesses…apartments and assisted care facilities. At cu earth science library in Boulder…more than 1000 books and several costumes for an upcoming production were damaged.

The icy temperatures forced to closure of several school districts as well.


In 1985…the most bitter cold spell of the winter season brought sub-zero temperatures to metro Denver. Daily low temperature records were broken at Denver.

Low temperatures reached 13 below zero on the 1st…12 below on the third…and 14 below on the 5th.


In 1989…one of the century’s worst doses of winter weather ravaged the entire state. Bitterly frigid weather moved into metro Denver on the 1st as snow buried many sections of the state. In metro Denver where 3 to 6 inches of snow fell…blowing snow and resultant poor visibilities caused a 46-car pile-up on I-25 in the middle of the city on the 4th. During the period…2 to 3 hour delays were common at Stapleton International Airport where snowfall from the storm totaled 4.3 inches and northeast winds gusted to 30 mph on the 1st.

A southwest Denver man was injured when a wind gust blew him and the front door he was holding off a porch. West winds gusted to 45 mph at Stapleton International Airport. The strongest winds occurred in Georgetown where a gust to 100 mph overturned a pick-up truck camper on I-70. The driver sustained only minor injuries.

In 2001…high winds developed briefly in the Front Range foothills. A spotter at Georgetown lake measured a peak wind gust to 90 mph.

In 2008…lightning struck a home in Englewood during an electrically charged snowstorm. A gas meter at the home was hit by lightning and burst into flames. The unusual thunderstorm produced a combination of snow and graupel. The graupel was up to one half inch in diameter. Total snow accumulations ranged from 1 to 4 inches across the southern Denver suburbs. Snowfall was only 0.6 inch at the former Stapleton International Airport.


In 1894…6.2 inches of heavy snowfall were measured over downtown Denver. East winds gusted to 25 mph on the 2nd.

The damage associated with the windstorm was extensive. Thirty 70-foot-tall power poles were damaged… Including several that supported high voltage lines transmitting electricity directly from generating plants. The combination of downed power poles…power lines…and trees resulted in outages for about 10 thousand residents. In Lafayette…power poles were sheared off for a mile and a quarter. The power outages primarily affected residents in Boulder…Broomfield…Lafayette…Louisville… And Fort Lupton. In addition to the outages…high winds ripped apart several roofs in Boulder…including the roof of the Boulder County jail. At Jefferson County Airport… Several planes were overturned and some hangars damaged or destroyed. Damage to the airport alone was estimated at 100 thousand dollars. In southern Jefferson County… Localized ground blizzards reduced visibilities in blowing snow to less than 20 feet along U.S. Highway 285…resulting in several accidents. In Pine Junction a downed tree damaged a nearby residence…when it crashed onto the roof. In Bailey…a downed tree crushed a vehicle parked in the resident’s driveway. Total damage estimates for the windstorm reached 3 million dollars…making it the fourth costliest on record at the time in Colorado. Other peak wind gusts include: 97 mph at Boulder…93 mph at the National Center for Atmospheric Research mesa lab in Boulder… 88 mph at Nederland…86 mph at Aspen Springs…and 83 mph at Blue Mountain near Coal Creek Canyon.

Denver International Airport canceled more than six hundred flights. In addition…snow and blowing snow produced near zero visibilities…forcing officials to close the westbound lanes of Interstate 70…between the Kansas state line and Denver… as well as the eastbound lanes from Denver to Limon. Other road closures included State Highway 86…between Kiowa and I-70. Across the Urban Corridor storm totals included: 22 inches in Broomfield; 21 inches at Lafayette…Louisville and Westminster; 20 inches at Northglenn; 19 inches at the National Weather Service in Boulder…Castle Rock… Centennial and Parker; 18 inches in Arvada…16.5 inches in Erie… 13.5 inches near Longmont; 11 inches in Lyons and 10 inches in Frederick.
