This week in Denver weather history - October 5th to October 11th

This week in Denver weather history - October 5th to October 11th

In our weekly look back at Denver weather history, we see a wide range of weather has occurred in the past.  From thunderstorms to rain to big time snowstorms, we can and have seen it all.

3-5   IN 1984…THE REMNANTS OF PACIFIC HURRICANE POLO PRODUCED
        HEAVY RAIN OVER NORTHEASTERN COLORADO.  MOST LOCATIONS
        RECEIVED BETWEEN 1.00 TO 2.50 INCHES OF RAIN…BUT 3.45
        INCHES FELL IN LITTLETON.  RAINFALL TOTALED 1.73 INCHES
        AT STAPLETON INTERNATIONAL AIRPORT…WHERE NORTH WINDS
        GUSTED TO 24 MPH. 
4-5   IN 1997…UNUSUALLY WARM WEATHER RESULTED IN TWO TEMPERATURE
        RECORDS.  HIGH TEMPERATURE OF 87 DEGREES ON THE 4TH EXCEEDED
        THE OLD RECORD SET IN 1922 BY ONE DEGREE.  HIGH TEMPERATURE
        OF 86 DEGREES ON THE 5TH EQUALED THE RECORD SET IN 1990 AND
        PREVIOUS YEARS.

5     IN 1962…UNUSUALLY SEVERE THUNDERSTORMS FOR THIS LATE IN THE
        SEASON AFFECTED AREAS FROM BOULDER NORTHWARD.  HAIL UP TO
        GOLF BALL SIZE AND STRONG GUSTY WINDS DID MUCH DAMAGE TO
        ROOFS…WINDOWS…AND SIGNS IN BOULDER.  HEAVY RAINFALL CAUSED
        LOCAL FLOODING.
      IN 1994…LIGHTNING CAUSED A POWER OUTAGE TO OVER 2400 HOMES
        FOR A FEW HOURS IN AND AROUND NEDERLAND IN THE FOOTHILLS
        SOUTHWEST OF BOULDER.  VERY STRONG WINDS ACCOMPANIED THE
        THUNDERSTORM.  THUNDERSTORM WINDS GUSTED TO 60 MPH AND HAIL
        TO 1/2 INCH DIAMETER FELL IN LAFAYETTE.  STRONG MICROBURST
        WINDS GUSTING TO 69 MPH NEAR STRASBURG CAUSED AN OIL RIG
        TO TOPPLE ONTO TWO VEHICLES…INJURING ONE PERSON.  THE
        STRONG WINDS IN THE AREA ALSO DOWNED A FEW POWER POLES…
        BUT CAUSED POWER OUTAGES TO ONLY A FEW HOMES.
      IN 1995…STRONG WINDS SPREAD FROM THE FOOTHILLS ONTO THE
        PLAINS.  WIND GUSTS TO 77 MPH WERE REPORTED ATOP SQUAW
        MOUNTAIN WEST OF DENVER.  ON THE PLAINS…WINDS GUSTED
        TO 60 MPH AT KENNESBURG AND TO 62 MPH NEAR STRASBURG.
        NORTH WINDS GUSTED TO 41 MPH AT DENVER INTERNATIONAL
        AIRPORT.

        WAS ONLY 46 DEGREES.
      IN 1910…LIGHT SMOKE FROM FOREST FIRES DRIFTED OVER THE
        CITY.
      IN 1976…AN ARCTIC COLD FRONT BROUGHT LIGHT SNOW OVER
        THE FOOTHILLS ABOVE 6 THOUSAND FEET.  TRAFFIC WAS
        SNARLED AT MANY LOCATIONS.  ONLY A TRACE OF SNOW
        FELL AT STAPLETON INTERNATIONAL AIRPORT WHERE
        RAINFALL TOTALED 0.20 INCH AND NORTHEAST WINDS GUSTED
        TO 41 MPH.
      IN 1991…THE BRILLIANT ORANGE SUNSET WAS APPARENTLY THE
        RESULT OF AN EXTENSIVE VOLCANIC SMOKE LAYER IN THE UPPER
        ATMOSPHERE.
      IN 1994…STRONG WEST TO NORTHWEST WINDS DEVELOPED IN THE
        FOOTHILLS ABOVE 9500 FEET.  A WIND GUST TO 78 MPH WAS
        RECORDED ATOP SQUAW MOUNTAIN WEST OF DENVER AND TO
        72 MPH AT WARD NORTHWEST OF BOULDER.  NORTHWEST WINDS

        OF METRO DENVER…AND THE PALMER DIVIDE.  SNOW ACCUMULATIONS
        RANGED FROM 8 TO 26 INCHES WITH DRIFTS FROM 3 TO 4 FEET
        IN PLACES.  THE HEAVIEST SNOW OCCURRED TO THE EAST AND
        SOUTHEAST OF THE CITY…CLOSING MOST MAJOR HIGHWAYS IN
        THAT AREA…INCLUDING I-70 FROM DENVER TO LIMON.  THE RED
        CROSS OPENED FOUR SHELTERS FOR PEOPLE WHO WERE STRANDED
        ALONG I-70 IN EASTERN COLORADO.  SINCE MANY TREES HAD NOT
        YET SHED THEIR LEAVES…THE STORM CAUSED SIGNIFICANT TREE
        DAMAGE.  ONE WOMAN IN DENVER WAS KILLED WHEN A TREE BRANCH…

        LONGMONT.  RAINFALL AMOUNTS WERE SIGNIFICANT AS STORM TOTALS
        RANGED BETWEEN 1.50 AND 2.50 INCHES.  THE STEADY RAINFALL
        TRIGGERED 3 ROCKSLIDES IN FOOTHILLS CANYONS.  TWO OF THE
        SLIDES OCCURRED ON STATE HIGHWAY 119 IN BOULDER CANYON AND
        THE LONGEST SLIDE…7 FEET IN LENGTH…ON STATE HIGHWAY 74 IN
        BEAR CREEK CANYON AT IDLEDALE.  NORTH WINDS WERE SUSTAINED
        TO AROUND 23 MPH WITH GUSTS TO 31 MPH AT DENVER INTERNATIONAL
        AIRPORT ON THE 9TH.  THE HIGH TEMPERATURE OF ONLY 34 DEGREES

        24-HOUR PRECIPITATION EVER RECORDED DURING THE MONTH OF
        OCTOBER.  NORTHWEST WINDS WERE SUSTAINED TO 48 MPH WITH

    This is a great new feature. Colorado’s weather is so varied and looking at it from a historical aspect really highlights it.
