... Wind chill, an overlooked danger...

Extremely cold air comes every winter in at least part of the
country and affects millions of people across the United States. The
Arctic air, combined with brisk winds, can lead to dangerously cold
wind chill values. The wind chill index helps you determine when
dangerous conditions develop that could lead to frostbite or
hypothermia. It takes into account heat loss from the human body to
its surroundings during cold and windy weather. The calculation
utilizes wind speed in miles per hour and temperature in degrees
fahrenheit. For example, a temperature of minus 5 degrees occurring
with a 20 mph wind gives a wind chill near minus 30 degrees. This
means that your body will lose heat at the same rate as it would if
the air temperature were minus 30 degrees with no wind. Wind chill
values near minus 25 degrees mean that frostbite is possible within
15 minutes.

Frostbite is the freezing of skin and the body tissue just beneath
it. It first affects exposed body tissue where blood circulation may
be limited such as your fingers, toes, nose and ears. To minimize
frostbite, make sure all body parts are well covered. When
frostbite starts, feeling is lost in the affected area and the
frozen tissue will take on a white or pale appearance. If you
suspect you are experiencing frostbite, hold the frostbitten area
closely against warm skin to return blood flow and warmth to the
affected area.

Hypothermia is a dangerously low body temperature and is the most
common winter weather killer. When you hear of a hiker, climber,
hunter or stranded traveler perishing from cold weather exposure,
hypothermia was the cause. Most people are surprised to learn that
hypothermia deaths can occur with temperatures between 30 and 50
degrees. If you or your clothing is wet, then hypothermia becomes
even more likely.

Warning signs of hypothermia include uncontrollable shivering,
memory loss, disorientation, slurred speech and drowsiness.
Immediate medical attention should be given to victims suspected of
suffering from hypothermia. If no help is available, the victim
should be warmed slowly with warm liquids along with dry clothing
and blankets.

The National Weather Service will issue wind chill advisories and
warnings when a deadly combination of wind and cold air threaten. To
learn more about wind chill, visit the National Weather Service
internet site: http://www.NWS.NOAA.Gov/om/cold/index.Shtml.

When cold weather threatens, follow these tips for survival:

Stay dry: wet clothing results in much faster heat loss from your
body. Wear Waterproof insulated boots.

Stay covered: wear mittens or gloves and wear a hat. At least half
of your body heat is lost if your head is not covered.

Dress layered: trapped air between loose fitting clothing helps to
insulate.

Stay informed: have a portable NOAA Weather Radio or your cell phone
nearby to keep you up-to-date with the latest forecasts and
warnings. Use wind chill temperatures to guide you in dressing
properly for the outdoors. On very cold days, minimize your
exposure to the outdoors if possible.

... Today in Metro Denver weather history...

17-19 in 1908... a moist... heavy... wet snowfall totaled 13.0 inches in
        downtown Denver over the 3 days. Rain from early morning
        on the 17th changed to snow by late afternoon and continued
        through the late morning of the 19th. Due to temperatures
        in the 30's and melting... the most snow on the ground was
        only 5.0 inches at 6:00 PM on the 18th. Northwest to
        northeast winds were sustained between 12 and 20 mph during
        the storm. Precipitation totaled 1.82 inches.
18-23 in 2003... an extended warm spell resulted in 5 new temperature
        records. The high temperature of 84 degrees on the 18th
        equaled the record high for the date. High temperatures
        of 86 degrees on the 19th... 83 degrees on the 21st... and 84
        degrees on the 22nd were record highs for the dates. Low
        temperature of 49 degrees on the 23rd was a record high
        minimum for the date. Low temperatures during the period
        were in the 40's and lower 50's.
19 in 1887... northwest winds sustained to 42 mph were recorded
        in the city.
      In 1982... 3 to 6 inches of snow fell over northwest Metro
        Denver... including Boulder. Only 1.2 inches of snowfall
        were recorded at Stapleton International Airport where
        north winds gusted to 35 mph. This was the first
        measurable snowfall of the season.
19-20 in 1990... an early winter storm dumped heavy snow across
        Metro Denver. Snowfall amounts ranged from 4 to 8 inches
        in the foothills above 6500 feet elevation... 4 to 7 inches
        in The Castle Rock area... and 2 to 5 inches across most of
        Metro Denver and Boulder. Snowfall totaled 3.6 inches at
        Stapleton International Airport where northwest winds
        gusting to 48 mph kicked up some blowing dust shortly
        after a cold frontal passage on the 19th. However...
        temperatures were warm enough to keep most roadways wet
        and slushy at lower elevations.
19-23 in 1906... heavy snowfall totaled 22.7 inches in the city over
        the 5 days. Rain changed to snow on the evening of the
        19th... and snow continued through the late afternoon of the
        23rd. The heaviest amount of snowfall... 16.0 inches... fell
        from 8:00 PM on the 20th to 8:00 PM on the 22nd. The most
        snow on the ground was 13.3 inches on the evening of the
        23rd. This was the first snow of the season and the only
        snow of the month. Winds during the storm were from the
        north at sustained speeds of 20 to 30 mph each day.
        Temperatures during the storm were generally in the 20's.
