A Wind Chill Warning means the combination of very cold air and
strong winds will create dangerously low wind chill values. This
will result in frost bite and lead to hypothermia or death if
precautions are not taken. If you must venture outdoors, be
certain to dress properly, with several layers of light-weight,
loose fitting clothing and making sure that all exposed skin is
covered.

A Winter Weather Advisory for snow means that periods of
accumulating snow will primarily cause travel difficulties. Roads
may rapidly become slippery once the snow begins, so motorists
should plan for a slower than normal trip. Be especially alert
when approaching bridges, overpasses, and curves.

...WINTER STORM WARNING REMAINS IN EFFECT UNTIL MIDNIGHT CST
TONIGHT...
...WIND CHILL ADVISORY REMAINS IN EFFECT UNTIL 6 AM CST TUESDAY...

* WHAT...For the Winter Storm Warning, heavy snow. Additional snow
  accumulations of 1 to 4 inches through late this evening. Storm

* WHERE...Portions of east central and southeast Missouri and 
  south central and southwest Illinois.

* WHEN...For the Winter Storm Warning, until midnight CST 
  tonight. For the Wind Chill Advisory, until 6 AM CST Tuesday.

* IMPACTS...This is a dangerous situation due to the combination 
  of poor road conditions and very cold temperatures. Travel 
  could be very difficult, and potentially life threatening if 
  you become stranded. Areas of blowing snow could significantly 
  reduce visibility. The cold wind chills could cause frostbite 
  on exposed skin in as little as 30 minutes.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Winter Storm Warning for snow means that heavy snowfall of
6 inches or more is expected. The rapid accumulation of snow will

travel with a full tank of gas, and carry a winter storm kit
which includes a shovel, flashlight, cellphone, food and water,
and blankets of extra warm clothing. 

A Wind Chill Advisory means that very cold air and strong winds
will combine to generate low wind chill values. This will result
in frost bite and lead to hypothermia if precautions are not
taken. If you must venture outdoors, make sure you wear a hat and
gloves, making sure all exposed skin is covered.

...WIND CHILL ADVISORY NOW IN EFFECT UNTIL 11 AM CST TUESDAY...
...WINTER STORM WARNING REMAINS IN EFFECT UNTIL MIDNIGHT CST
TONIGHT...

* WHAT...For the Winter Storm Warning, snow. Additional snow 
  accumulations of 1 to 3 inches. Winds gusting as high as 30 mph.
  For the Wind Chill Advisory, very cold wind chills. Wind chills
  as low as 15 below zero.

* WHERE...Portions of east central Missouri and south central 
  and southwest Illinois.

* WHEN...For the Winter Storm Warning, until midnight CST 
  tonight. For the Wind Chill Advisory, until 11 AM CST Tuesday.

* IMPACTS...Plan on slippery road conditions. Areas of blowing
  snow could significantly reduce visibility. The cold wind 
  chills could result in hypothermia if precautions are not taken.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Winter Storm Warning for snow means that heavy snowfall of
6 inches or more is expected. The rapid accumulation of snow will
make travel extremely difficult, if not impossible. If travel is
necessary, make sure to exercise extreme caution. Begin your
travel with a full tank of gas, and carry a winter storm kit
which includes a shovel, flashlight, cellphone, food and water,
and blankets of extra warm clothing.

A Wind Chill Advisory means that very cold air and strong winds
will combine to generate low wind chill values. This will result
in frost bite and lead to hypothermia if precautions are not
taken. If you must venture outdoors, make sure you wear a hat and
gloves, making sure all exposed skin is covered.

In Illinois, the latest road conditions can be obtained on the
Internet at www.gettingaroundillinois.com. In Missouri, the
latest road conditions can be obtained on the Internet at
