For the Wind Chill Advisory, until 6 AM CST Tuesday. * IMPACTS...Travel could be very difficult. The hazardous conditions could impact the morning and evening commutes on Monday. 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.

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.

Additional snow accumulations of 1 to 4 inches through late this evening. Storm total snow accumulations of 5 to 9 inches are expected. For the Wind Chill Advisory, very cold wind chills. Wind chills as low as 20 below zero. * 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 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.

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.
