U.S. National Weather Service - Jackson, Mississippi: A long duration of cold weather rare for this time of year is expected from tonight Christmas morning. Temperatures as low as single digits in North Mississippi to teens farther south are expected. Across much of our region, temperatures will remain below freezing from late tonight through the morning hours on Christmas Day. In addition, strong and gusty north winds will result in wind chill readings below zero by Friday morning and in the single digits Saturday morning. Hypothermia will be likely with prolonged exposure, with frostbite being possible in 30 minutes or less in the extreme threat area. Damage to exposed pipes will be likely and water main breaks can be expected. Be sure family, neighbors, and pets have a warm place to stay.
