Many notable weather events have occurred in Denver this week in the past, some recently.  It was just last year that a windstorm knocked down trees and powerlines in Boulder.  Three years ago, we saw an end to 61 days straight with snow cover – the second longest streak in Denver history.

13-14

Snow and wind are the two dominant weather conditions seen on our look back at this week in Denver weather history.  Three years ago, the second of two major winter storms buried Denver and closed highways.  Two years ago, damaging winds that downed trees and caused power outages occurred.

The week leading up to Christmas is hectic enough but when you through in severe weather, it can be overwhelming.  This week marks a number of notable weather events in Denver weather history but two stand out.  Most recently was the storm three years ago that became the seventh biggest snowstorm in Denver weather history.  Of course probably the most memorable for longtime Denver residents is the Christmas Eve storm of 1982 that buried the city for the holiday and for days afterwards.

In 2004…strong downslope winds developed over the eastern mountain slopes and spread over metro Denver.  Peak wind gusts approached 100 mph along the foothills of Boulder County.  In superior…a 1200-square-foot section of roof was peeled off the gymnasium at monarch high school. Two semi-trailers were toppled on Colorado Highway 58 at McIntyre Street and another at c-470 and West Bowles Avenue.  Two airplanes were damaged by wind-blown debris at Jefferson County airport.  The high winds forced the closure of State Highway 93 between Golden and Boulder for approximately two hours.  Insurance agents estimated 650 to 850 homes suffered wind damage in the Boulder and Louisville areas.  In addition…downed trees and power lines left about 1000 residents…mainly in the Boulder area…without electricity.  At least three people suffered minor injuries in the storm.  Peak wind reports included:  95 mph in superior…92 mph at Jefferson County airport…85 mph in Golden…81 mph in Boulder…80 mph in Broomfield and Evergreen…and 79 mph in Louisville.  West northwest winds gusted to 59 mph at Denver International Airport.

December can of course be cold and that is why Chinook winds are sometimes welcomed as they bring warm air to the Front Range.  However, those winds can also cause a great deal of damage if they blow too hard and we see that in our look back at this week in Denver weather history.  Particularly notable were winds on December 14th & 15th which caused accidents, toppled power poles and fences, ripped off roofs and more.

As we enter Denver’s second snowiest month, we of course see plenty of events involving that dominant weather condition.  Sadly we also see two occassions when the winter-like weather turned deadly.

In 2004…heavy snow fell in and near the foothills of Jefferson and Douglas counties.  Storm total snowfall included:  14.5 inches in Aspen Park…10 inches at Roxborough State Park and near Sedalia…8 inches near Bergen Park…and 7 inches in Highlands Ranch.  Snowfall totaled only 3.2 inches in the Denver Stapleton area.  Post-frontal northeast winds gusted to 41 mph at Denver International Airport.

On the 1st:

In 1896…northwest Chinook winds sustained to 40 mph with gusts to 46 mph warmed the temperature to a high of 60 degrees in the city.
 
In 1973…wind gusts to 92 mph were recorded in Boulder. West winds gusted to 41 mph at Stapleton International Airport where the Chinook winds warmed the temperature to a high of 70 degrees.
 
In 1989…a 39-year-old Lakewood man in a motorized wheelchair was found dead of exposure early in the morning after an overnight snowfall dumped 3 to 6 inches of snow across metro Denver.

From the 1st to the 2nd:

In 1892…snowfall totaled 5.0 inches in downtown Denver. This was the only snow of the month.
 
In 1956…heavy snowfall totaled 7.0 inches at Stapleton Airport.  The storm was accompanied by much blowing and drifting snow.  North winds gusted to 47 mph.
 
In 1991…the storm system which hit the Front Range at the end of October finished the job during the start of November.  Six inches of new snow were recorded at both Rollinsville and Morrison…while 2.9 inches of snow fell at Stapleton International Airport where northeast winds gusted to 17 mph.  The temperature climbed to a high of only 19 degrees on the 2nd…setting a record low maximum for the date.
 
In 1995…a winter storm dropped 5 to 8 inches of snow in the Front Range foothills.  The exception was at Golden gate canyon where a foot of new snow was measured.  Icy roads…fog…and blowing snow along I-70 in the foothills west of Denver caused dozens of accidents.  One man was killed when he lost control of his vehicle and was ejected when his truck hit a median and rolled over.  At least 20 other accidents involved minor injuries.  Only 1.0 inch of snow fell at the site of the former Stapleton International Airport where some freezing rain also fell.
