January 18 to January 24 - This week in Denver weather history.

Our look back in Denver weather history for this week is dominated by the seemingly ever present high winds.  There are numerous incidents of those causing damage and injury.  Also notable though was a snowstorm in 1948 that dumped snow for more than 92 hours straight, a protracted cold spell in 1962 that lasted nearly a week and claimed lives and more recently the snowstorms in January 2007 that dumped snow on the region.

14-21

IN 1930…A PROTRACTED COLD SPELL OCCURRED WHEN LOW TEMPERATURES PLUNGED BELOW ZERO ON 8 CONSECUTIVE DAYS.  THE COLDEST LOW TEMPERATURES OF 20 DEGREES BELOW ZERO ON THE 17TH AND 19 DEGREES BELOW ZERO ON THE 16TH WERE RECORD MINIMUMS FOR THE DATES.  HIGH TEMPERATURES DURING THE PERIOD RANGED FROM 18 ON THE 18TH TO ZERO ON THE 20TH.  TWO DEGREES ON THE 15TH WAS A RECORD LOW MAXIMUM TEMPERATURE FOR THE DATE.

15-23

IN 1962…A PROTRACTED COLD SPELL KEPT METRO DENVER IN THE DEEP FREEZE FOR MORE THAN A WEEK.  FROM THE 15TH THRU THE 23RD…LOW TEMPERATURES WERE ZERO OR BELOW FOR 9 CONSECUTIVE DAYS…BUT A DAILY RECORD LOW WAS SET ONLY ON THE 22ND WHEN THE TEMPERATURE DIPPED TO 14 DEGREES BELOW ZERO.  A RECORD LOW MAXIMUM FOR THE DATE WAS ALSO SET ON THE 22ND WHEN THE TEMPERATURE CLIMBED TO ONLY 11 DEGREES.  THE COLDEST HIGH TEMPERATURE WAS 3 DEGREES ABOVE ZERO ON THE 21ST…WHICH DID NOT BREAK THE RECORD.  THE PROTRACTED COLD WAS BROKEN FOR ONLY A FEW HOURS ON THE AFTERNOON OF THE 20TH WHEN CHINOOK WINDS WARMED THE TEMPERATURE TO A HIGH OF 38 DEGREES BEFORE ANOTHER SURGE OF COLD ARCTIC AIR PLUNGED TEMPERATURES BACK INTO THE DEEP FREEZE THAT EVENING.  THE SEVERE COLD CAUSED MUCH DAMAGE TO WATER SYSTEMS.  A WOMAN WAS FROZEN TO DEATH AT MORRISON.  THERE WERE OTHER DEATHS ATTRIBUTABLE TO THE WEATHER…INCLUDING TRAFFIC DEATHS AND HEART ATTACKS FROM OVEREXERTION.

16-18

IN 1943…LIGHT SNOWFALL TOTALED 3.2 INCHES OVER THE 3 DAYS. THIS WAS THE ONLY MEASURABLE SNOW OF THE MONTH.  NORTH WINDS WERE SUSTAINED TO 20 MPH ON THE 16TH.

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.

26-28

IN 1979 A HEAVY SNOW STORM DUMPED 6 TO 10 INCHES OF SNOW OVER THE METRO AREA AND 15 TO 20 INCHES AT BOULDER WITH UP TO 2 FEET IN THE FOOTHILLS WEST OF BOULDER.  HEAVY SNOWFALL TOTALED 6.0 INCHES AT STAPLETON INTERNATIONAL AIRPORT WHERE NORTH WINDS GUSTED TO 21 MPH.  MOST OF THE SNOW… 4.8 INCHES…FELL 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.

Our look back in Denver weather history for this week is punctuated by hurricane force winds – numerous times.  Some of these storms reached 120 mph, overturned semis, ripped roofs off and more.  Also notable is the blizzard we suffered through two years ago this week.

From the National Weather Service:

…THIS WEEK IN METRO DENVER WEATHER HISTORY…

2-17 

In 1939…more than 2 weeks of unseasonably warm weather made the month the 3rd warmest on record.  Seven daily temperature records were set…including the all time record high temperature for the month of 79 degrees on the 5th.  Daytime highs were balmy with 14 days in the 60’s and 70’s.  Low temperatures dipped to freezing or below on only 5 days.  The period was dry with only a trace of snow on the 12th.

3-15 

In 1972…a protracted cold spell held an icy grip on metro Denver when maximum temperatures never reached above freezing for 10 consecutive days from the 3rd through the 12th and minimum temperatures dipped below zero on eleven consecutive days from the 5th through the 15th. Daily low temperature records were set with 15 degrees below zero on the 5th…17 degrees below zero on the 6th… And 18 degrees below zero on the 10th.  Daily record low maximum readings were set with 3 degrees on the 6th and 6 degrees on the 9th.  The very cold temperatures were caused by 3 to 5 inches of snow cover and a Canadian air mass.
