      IN 1970...SNOWFALL OF 0.3 INCH CONTAINED ONLY 0.01 INCH OF
        MELTED SNOW.  THIS WAS THE ONLY MEASURABLE SNOW AND
        PRECIPITATION FOR THE MONTH...MAKING IT THE DRIEST AND
        LEAST SNOWIEST FEBRUARY ON RECORD.  SNOWFALL ALSO WAS
        ONLY 0.3 INCH ON FEBRUARY 22-23...1992...EQUALING THE

        NORTHERN JEFFERSON COUNTY.  WINDS GUSTING TO 59 MPH IN
        LAKEWOOD DOWNED A FEW TREE BRANCHES IN RESIDENTIAL AREAS.
        WEST WINDS GUSTED TO 37 MPH AT STAPLETON INTERNATIONAL

        WEST WINDS WERE SUSTAINED TO 18 MPH ON THE 1ST.
1-3   IN 1996...COLD ARCTIC AIR PLUNGED TEMPERATURES BELOW ZERO
        FOR MORE THAN 35 CONSECUTIVE HOURS FROM LATE ON THE 1ST
        UNTIL SUNRISE ON THE 3RD.  THE TEMPERATURE WARMED TO ONLY
        1 DEGREE BELOW ZERO ON THE 2ND AFTER A RECORD LOW OF
        16 DEGREES BELOW ZERO.
1-4   IN 2011...A FRIGID ARCTIC AIRMASS SETTLED INTO FRONT RANGE
        URBAN CORRIDOR.  AT DENVER INTERNATIONAL AIRPORT...
        OVERNIGHT LOW TEMPERATURES...FROM THE 1ST TO THE 3RD...
        WERE 13 BELOW ZERO...17 BELOW ZERO AND ZERO RESPECTIVELY.
        THE ICY TEMPERATURES CAUSED PIPES TO CRACK AND BURST
        FOLLOWING THE FREEZE.  IN LOVELAND...FIREFIGHTERS
        RESPONDED TO MORE THAN A DOZEN WATER PIPE BREAKS...MOST
        IN FIRE SPRINKLER SYSTEMS AT BUSINESSES...APARTMENTS AND
        ASSISTED CARE FACILITIES.  AT CU EARTH SCIENCE LIBRARY
        IN BOULDER...MORE THAN 1000 BOOKS AND SEVERAL COSTUMES
        FOR AN UPCOMING PRODUCTION WERE DAMAGED.  AT THE COUNTY
        COURTS ADMINISTRATION BUILDING IN JEFFERSON COUNTY...A
        STEADY STREAM OF WATER FROM A CRACK ON THE 5TH FLOOR...
        WENT UNNOTICED ON THE 3RD AND FLOODED ALL THE FLOORS OF
        THE ADMINISTRATION WING OVERNIGHT.  AS A RESULT...MUCH OF
        THE OFFICE EQUIPMENT...FURNITURE AND CARPET SUSTAINED
        WATER DAMAGE.  A BURST SPRINKLER LINE CAUSED MINOR
        DAMAGE AT THE PLATTE VALLEY MEDICAL CENTER IN BRIGHTON.
        THE ICY TEMPERATURES FORCED TO CLOSURE OF SEVERAL SCHOOL
        DISTRICTS AS WELL.
1-5   IN 1985...THE MOST BITTER COLD SPELL OF THE WINTER SEASON

        WAS ONLY 2 DEGREES ABOVE ZERO ON THE 1ST...SETTING A RECORD
        LOW MAXIMUM FOR THE DATE.  LOW TEMPERATURES REACHED 13 BELOW
        ZERO ON THE 1ST...12 BELOW ON THE THIRD...AND 14 BELOW ON THE

1-6   IN 1989...ONE OF THE CENTURY`S WORST DOSES OF WINTER WEATHER
        RAVAGED THE ENTIRE STATE.  BITTERLY FRIGID WEATHER MOVED
        INTO METRO DENVER ON THE 1ST AS SNOW BURIED MANY SECTIONS
        OF THE STATE.  IN METRO DENVER WHERE 3 TO 6 INCHES OF SNOW
        FELL...BLOWING SNOW AND RESULTANT POOR VISIBILITIES CAUSED
        A 46-CAR PILE-UP ON I-25 IN THE MIDDLE OF THE CITY ON THE
        4TH.  DURING THE PERIOD...2 TO 3 HOUR DELAYS WERE COMMON AT
        STAPLETON INTERNATIONAL AIRPORT WHERE SNOWFALL FROM THE
        STORM TOTALED 4.3 INCHES AND NORTHEAST WINDS GUSTED TO 30
        MPH ON THE 1ST.  INTENSE COLD ACCOMPANIED THE STORM.
        TEMPERATURES IN DENVER STAYED BELOW ZERO CONTINUOUSLY FOR

        RECORD.  WIND CHILL TEMPERATURES REACHED 50 DEGREES BELOW
        ZERO.  THE MERCURY DIPPED TO 24 DEGREES BELOW ZERO ON THE
        5TH...SETTING A RECORD FOR THE DATE.  THIS WAS THE CITY`S

        LINES FROZE AND BROKE.  THOUSANDS OF CARS FAILED TO START.
        ON THE 3RD...A 57-YEAR-OLD WOMAN DIED OF HYPOTHERMIA IN AN
        ARVADA PARK.  EIGHTEEN HIGH SCHOOL STUDENTS WERE TREATED
        FOR HYPOTHERMIA AFTER A 2-HOUR RIDE THROUGH JEFFERSON
        COUNTY IN AN UNHEATED BUS.  AT LEAST 2 CASES OF FROSTBITE
        WERE REPORTED; THERE WERE UNDOUBTEDLY MANY MORE.

        3RD IS THE COLDEST MAXIMUM TEMPERATURE EVER RECORDED IN
        DENVER.
2     IN 1890...WEST WINDS WERE SUSTAINED TO 44 MPH WITH AN
        EXTREME VELOCITY OF 45 MPH.  THE CHINOOK WINDS WARMED
        THE TEMPERATURE TO A HIGH OF 66 DEGREES.
      IN 1970...HIGH WINDS CAUSED SCATTERED DAMAGE ALONG THE
        FOOTHILLS FROM GOLDEN NORTH.  A GARAGE IN BOULDER WAS
        DEMOLISHED.  BROKEN WINDOWS AND ROOF DAMAGE WERE REPORTED
        IN GOLDEN.  WIND GUSTS FROM 60 TO 100 MPH WERE RECORDED IN

      IN 1995...THE SECOND MORNING IN A ROW OF STRONG WINDS RAGED
        IN THE FOOTHILLS AND ADJACENT LOWER ELEVATIONS.  WINDS
        GUSTED BETWEEN 70 AND 85 MPH IN THE FOOTHILLS AND 45 TO
        50 MPH ON THE PLAINS.  A TREE WAS BLOWN ONTO HIGH VOLTAGE
        POWER LINES IN A WEST DENVER SUBURB.  THE FENCE THAT THE
        WIRE LANDED ON CAUGHT FIRE...BUT DID NO DAMAGE TO THE
        SURROUNDING STRUCTURES.  A SOUTHWEST DENVER MAN WAS
        INJURED WHEN A WIND GUST BLEW HIM AND THE FRONT DOOR HE
        WAS HOLDING OFF A PORCH.  WEST WINDS GUSTED TO 45 MPH AT
        STAPLETON INTERNATIONAL AIRPORT.  THE STRONGEST WINDS
        OCCURRED IN GEORGETOWN WHERE A GUST TO 100 MPH OVERTURNED
        A PICK-UP TRUCK CAMPER ON I-70.  THE DRIVER SUSTAINED ONLY
        MINOR INJURIES.
      IN 2001...HIGH WINDS DEVELOPED BRIEFLY IN THE FRONT RANGE
        FOOTHILLS.  A SPOTTER AT GEORGETOWN LAKE MEASURED A
        PEAK WIND GUST TO 90 MPH.
      IN 2008...LIGHTNING STRUCK A HOME IN ENGLEWOOD DURING AN
        ELECTRICALLY CHARGED SNOWSTORM.  A GAS METER AT THE HOME
        WAS HIT BY LIGHTNING AND BURST INTO FLAMES.  THE UNUSUAL
        THUNDERSTORM PRODUCED A COMBINATION OF SNOW AND GRAUPEL.
        THE GRAUPEL WAS UP TO ONE HALF INCH IN DIAMETER.  TOTAL
        SNOW ACCUMULATIONS RANGED FROM 1 TO 4 INCHES ACROSS THE
        SOUTHERN DENVER SUBURBS.  SNOWFALL WAS ONLY 0.6 INCH AT
        THE FORMER STAPLETON INTERNATIONAL AIRPORT.
2-3   IN 1894...6.2 INCHES OF HEAVY SNOWFALL WERE MEASURED OVER
        DOWNTOWN DENVER.  EAST WINDS GUSTED TO 25 MPH ON THE 2ND.
      IN 1999...A POWERFUL CHINOOK WINDSTORM STRUCK THE FOOTHILLS
        AND ADJACENT PLAINS.  SEVERAL LOCATIONS REGISTERED WIND
        GUSTS IN EXCESS OF 100 MPH...INCLUDING: 127 MPH ATOP
        SUGARLOAF MOUNTAIN...120 MPH AT LAFAYETTE...119 MPH AT
        WONDERVU...104 MPH AT COAL CREEK...103 MPH AT THE ROCKY
        FLATS ENVIRONMENTAL TEST FACILITY AND 100 MPH IN
        LOUISVILLE.  THE DAMAGE ASSOCIATED WITH THE WINDSTORM WAS
        EXTENSIVE.  THIRTY 70-FOOT-TALL POWER POLES WERE DAMAGED...
        INCLUDING SEVERAL THAT SUPPORTED HIGH VOLTAGE LINES
        TRANSMITTING ELECTRICITY DIRECTLY FROM GENERATING PLANTS.
        THE COMBINATION OF DOWNED POWER POLES...POWER LINES...AND
        TREES RESULTED IN OUTAGES FOR ABOUT 10 THOUSAND RESIDENTS.
        IN LAFAYETTE...POWER POLES WERE SHEARED OFF FOR A MILE
        AND A QUARTER.  THE POWER OUTAGES PRIMARILY AFFECTED
        RESIDENTS IN BOULDER...BROOMFIELD...LAFAYETTE...LOUISVILLE...
        AND FORT LUPTON.  IN ADDITION TO THE OUTAGES...HIGH WINDS
        RIPPED APART SEVERAL ROOFS IN BOULDER...INCLUDING THE ROOF
        OF THE BOULDER COUNTY JAIL.  AT JEFFERSON COUNTY AIRPORT...
        SEVERAL PLANES WERE OVERTURNED AND SOME HANGARS DAMAGED OR
        DESTROYED.  DAMAGE TO THE AIRPORT ALONE WAS ESTIMATED AT
        100 THOUSAND DOLLARS.  IN SOUTHERN JEFFERSON COUNTY...
        LOCALIZED GROUND BLIZZARDS REDUCED VISIBILITIES IN BLOWING
        SNOW TO LESS THAN 20 FEET ALONG U.S. HIGHWAY 285...RESULTING
        IN SEVERAL ACCIDENTS.  IN PINE JUNCTION A DOWNED TREE
        DAMAGED A NEARBY RESIDENCE...WHEN IT CRASHED ONTO THE ROOF.
        IN BAILEY...A DOWNED TREE CRUSHED A VEHICLE PARKED IN THE
        RESIDENT`S DRIVEWAY.  TOTAL DAMAGE ESTIMATES FOR THE
        WINDSTORM REACHED 3 MILLION DOLLARS...MAKING IT THE FOURTH
        COSTLIEST ON RECORD AT THE TIME IN COLORADO.  OTHER PEAK
        WIND GUSTS INCLUDE:  97 MPH AT BOULDER...93 MPH AT THE
        NATIONAL CENTER FOR ATMOSPHERIC RESEARCH MESA LAB IN BOULDER...

        SNOW TO AREAS IN AND NEAR THE FRONT RANGE FOOTHILLS AND PALMER
        DIVIDE...WITH BLIZZARD CONDITIONS OVER THE NORTHEAST PLAINS OF
        COLORADO. IN THE FRONT RANGE FOOTHILLS...THE SNOW PILED UP TO
        OVER 4 FEET IN SOME AREAS. ACROSS THE PALMER DIVIDE...THE
        COMBINATION OF SNOW AND GUSTY WINDS RESULTED IN ROAD CLOSURES
        WITH SNOW DRIFTS RANGING FROM 2 TO 5 FEET IN DEPTH. NORTHERLY
        WINDS 15 TO 25 MPH WERE COMMON WITH GUSTS TO 40 MPH. SEVERAL
        SNOWFALL RECORDS WERE ALSO SET IN DENVER. AT DENVER
        INTERNATIONAL AIRPORT...12.5 INCHES OF SNOW FEET ON THE 3RD
        SHATTERED THE PREVIOUS RECORD OF 7.5 INCHES FOR THE DATE. IT
        ALSO SET A NEW DAILY RECORD FOR THE ENTIRE MONTH OF FEBRUARY.
