I-70 had to be closed in both directions until the accidents could be cleaned up. Strong winds forced the closure of State Highway 93 between Golden and Boulder…when the road became icy and snowpacked from localized ground blizzards. Another semi- truck was blown over near the intersection of State Highways 72 and 93 atop Rocky Flats. Scattered power outages were reported across northern and western sections of metro Denver…affecting around 2000 residents. In Boulder…several pine trees were uprooted by the high winds.

Winds estimated at 60 to 75 mph picked up rocks and shattered the windows of a car in Louisville.  The strong winds blew down and partially destroyed two houses under construction just north of Thornton.  West winds gusted to 53 mph at Denver International Airport where the visibility was briefly reduced to 1/2 mile in blowing dust.

In 2016…two brief but powerful gustnadoes developed along a convergence line that formed in the suburbs just north and west of Denver. Three power poles were knocked down. In addition…a small storage shed was destroyed.

22-23

In 1936…heavy snowfall of 7.7 inches was measured in downtown Denver.  The heavy wet snowfall formed a thick coating of snow on trees and shrubs…but caused little damage.  North winds were sustained to 15 mph.

In 1984…around a half foot of new snow fell across metro Denver…causing flight delays at Stapleton International Airport where snowfall totaled 6.0 inches and north winds gusted to 31 mph.  Up to a foot of snow fell in the foothills.  Icy roads produced numerous traffic accidents.

In 2011…strong bora winds developed along the Front Range following the passage of a storm system. Peak wind gusts included: 87 mph at the National Wind Technology Center; 82 mph…6 miles northwest of Boulder; 72 mph at Front Range airport in Broomfield; 71 mph at Longmont; and 64 mph…4 miles west of Lakewood. At Denver International Airport…a peak wind gust of 48 mph from the west was observed on the 22nd.

In 2013…a wet early spring snowstorm brought heavy snow to parts of the Front Range foothills and urban corridor. The heaviest snowfall occurred near the Front Range foothills and palmer divide. Near blizzard conditions forced the closure of interstate 70 east of Denver. In the foothills… Storm totals included: 14.5 inches near Conifer; 14 inches just southwest of Eldorado Springs and Intercanyon; 13 inches near Indian Hills; 12.5 inches near Pinecliffe; 11.5 inches near Golden; 11 inches near Jamestown and Roxborough; 10.5 inches near Brookvale and 10 inches at Genesee. Across the urban corridor and Palmer Divide… Storm totals included: 12.5 inches…8 miles southeast of Watkins; 10.5 inches in Boulder…Centennial and Northglenn; 9.5 inches…just south of Aurora; 9 inches in Westminster; 8 inches at Lafayette; 7.5 inches near Morrison; 7 inches in Arvada…Bennett…Brighton; 6 inches in Highlands Ranch… Longmont…Louisville and Thornton. Officially…11.6 inches of snow fell at DIA from the evening of the 22nd to the afternoon of the 23rd…which set a new two-day snowfall record in Denver for the date. In addition…a peak wind gust to 33 mph was observed from the east on the 22nd with a gust to 30 mph from the north on the 23rd.

In 2016…a powerful blizzard developed across the Front Range of Colorado late on the 22nd and continued through much of the 23rd. The storm tracked east-southeast across Utah on the 22nd…and then into southeast Colorado by the morning of the 23rd. The storm rapidly intensified as it reached eastern Colorado…producing extremely heavy and intense snowfall with snowfall rates exceeding 3 inches per hour at times. In addition to heavy snow…strong winds gusting in excess of 50 mph east of I-25 produced widespread blizzard conditions and zero visibilities. The storm initially began with rain on the plains…but quickly changed over to snow during the early morning hours of the 23rd. Snowfall rates of 1 to 2 inches per hour were common…with several inches of snow already accumulating for the morning commute. Many roads became impassable due to the depth of fallen snow…drifting snow…and near zero visibilities during the day. During the peak of the storm… snowfall rates reached or exceeded 3 inches per hour. Widespread road closures occurred…including I-76 from northeast of Denver to the Nebraska state line…I-70 east of Denver to the Kansas state line…and much of I-25… from near Castle Rock to Colorado Springs. The Colorado Department of Transportation estimated over two thousand vehicles became trapped on I-25 near Monument Hill alone… with hundreds of stuck or abandoned cars elsewhere. Numerous power outages occurred as heavy wet snow accumulated on trees…despite the strong winds. At the peak…several hundred thousand residents along the Front Range were without power. Denver International Airport was closed for 7 hours during and just after the peak of the blizzard…with around 1300 cancelled flights. The power outages shut down the fuel farm pumps…the deicing facility…as well as train service to the concourses at the airport. Pea Boulevard…the main road to the airport…was impassable for much of the day. It was the first time since December 21…2006 that Denver International Airport had been shut down due to extreme winter weather conditions. One to 2 feet of snow fell across much of the Front Range Foothills and Urban Corridor. In the foothills of northern Jefferson County…31.5 inches of snowfall measured at Pinecliffe. Most of the snow fell within a 12-hr period from the early morning into the afternoon. A peak wind gust of 59 mph recorded at Denver International Airport. South of Denver…over the Palmer Ridge…12 to 18 inches of snow was reported…with 6 to 10 inches across the adjacent plains. The official snowfall measurement at Denver International Airport was 13.1 inches. In addition…the snow was very heavy and wet…with many areas receiving 1 to 2 inches precipitation. In the foothills…some locations received nearly 3 inches of water from this storm.
