High winds and arctic cold, the two primary weather conditions we expect to see this time of year, dominate our look back at this week in Denver weather history.

31-6 

IN 1973…THE 31ST MARKED THE START OF A PROTRACTED COLD SPELL THAT EXTENDED INTO JANUARY OF 1974 WHEN TEMPERATURES DIPPED BELOW ZERO ON 7 CONSECUTIVE DAYS.  RECORD DAILY MINIMUM READINGS OCCURRED ON THE 3RD AND 5TH WHEN THE TEMPERATURE PLUNGED TO 17 DEGREES BELOW ZERO ON BOTH DAYS. A RECORD LOW DAILY MAXIMUM TEMPERATURE OF ONLY 4 DEGREES OCCURRED ON THE 5TH.

31-7 

IN 1941…A PROTRACTED COLD SPELL THROUGH JANUARY 7…1942… PRODUCED BELOW ZERO LOW TEMPERATURES ON 7 OF THE 8 DAYS.

December 28 to January 3 - This week in Denver weather history.

This week in Denver weather history is very interesting for a couple of reasons.  First is the two year anniversary of the holiday snow storms of 2006 as it was from December 27th to the 28th that the second major storm in a week buried the city even further in a blanket of snow.  Second, we see many occurrences of high winds, some damaging, which reminds us that the winds we have been experiencing and will continued to experience this week aren’t all that unusual. 

25-31

IN 1980…TEMPERATURES WERE UNUSUALLY WARM DURING THE WEEK BETWEEN CHRISTMAS AND NEW YEAR`S.  HIGH TEMPERATURES FOR THE WEEK RANGED FROM THE MID-50`S TO THE MID-70`S.  FOUR TEMPERATURE RECORDS WERE SET.  RECORD HIGHS OCCURRED ON THE 26TH WITH 68 DEGREES…THE 27TH WITH 75 DEGREES…AND THE 30TH WITH 71 DEGREES.  A RECORD HIGH MINIMUM TEMPERATURE OF 41 DEGREES OCCURRED ON THE 27TH.

27-28

IN 1997…HIGH WINDS COMBINED WITH FRESH SNOW FROM A PREVIOUS STORM CAUSED HIGHWAYS TO BECOME SLICK FROM DRIFTING SNOW AND NEAR WHITEOUT CONDITIONS IN LOCALIZED GROUND BLIZZARDS. STRONG WINDS BLEW SNOW ACROSS THE RUNWAYS AT CENTENNIAL AIRPORT…WHICH GLAZED OVER AND FORMED AREAS OF ICE.  TWO PLANES WERE DAMAGED WHEN THEY SLID OFF THE RUNWAY WHILE LANDING.  NO INJURIES WERE REPORTED.  NUMEROUS ACCIDENTS ALSO OCCURRED ON I-25 AND I-70 AS ICE FORMED UNDER THE SAME CONDITIONS.  A ROLLOVER ACCIDENT WHICH INJURED 4 PEOPLE ON STATE HIGHWAY 93 NEAR THE ROCKY FLATS ENVIRONMENTAL TEST FACILITY WAS ALSO ATTRIBUTED TO THE HIGH WINDS.  THE HIGH WINDS CAUSED AN OFFICE BUILDING AND SHOWROOM UNDER CONSTRUCTION IN GOLDEN TO COLLAPSE. THE LARGEST WALL WAS 180 FEET LONG AND 28 FEET HIGH. SOME HIGH WIND REPORTS INCLUDED:  86 MPH AT GOLDEN GATE CANYON…72 MPH NEAR CONIFER…AND 70 MPH AT JEFFERSON COUNTY AIRPORT AND THE NATIONAL CENTER FOR ATMOSPHERIC RESEARCH ON THE MESA NEAR BOULDER.  WEST-NORTHWEST WINDS GUSTED TO 53 MPH AT DENVER INTERNATIONAL AIRPORT ON THE 27TH.
