Parts of Mississippi could see snow, be under freeze warning this week. See where, when

A winter storm system is set to sweep across the southern U.S. this week and is expected to bring snow and some ice and wintry mix to states along the Gulf coast.

The storm is set to start in Texas on Wednesday night and move toward the eastern seaboard. Parts of the South will get 4 to 8 inches of snow. The National Weather Service expects several inches of snow in the Dallas area, and the weather system will move northeast through the weekend. Nashville and Atlanta also could see hazardous conditions.

The southeast has already been feeling the effects of Arctic air that moved in a few days ago, and the storm is expected to delay travel including affecting road conditions in areas not accustomed to heavy snow and potentially affecting airports.

Parts of Mississippi could see freezing temperatures and some snow, though previous forecasts calling for wintery weather in most of the state have been updated. The latest forecasts look like central and north Mississippi will have the strongest chances for snow, sleet and freezing temperatures.

What will the winter storm bring to Mississippi?

The AccuWeather and National Weather Service forecasts for the Jackson region through Friday have some slight differences. The biggest one is that while AccuWeather calls for a 25% chance of precipitation Thursday and a 99% chance with cold rain on Friday, the NWS says rain and sleet are likely Thursday night with a strong chance of showers on Friday.

Northern areas of the Magnolia State are under a winter storm watch Thursday and Friday. The NWS is predicting rain and snow chances in Greenwood, Oxford and Columbus/West Point/Starkville starting after midnight Thursday night and through Friday evening.

The Hattiesburg forecast now calls for showers Thursday night through Friday night. The overnight low Thursday is 35 degrees. Friday weather has a high of 46 and a low of 31.

The NWS New Orleans office issued a freeze warning Wednesday night for Gulfport. That area is set to get rain Thursday and Friday, but temperatures are expected to stay above freezing.

How should I prepare for extreme cold, winter weather?

The Mississippi Emergency Management Agency encourages residents to be ready for winter weather. Extreme cold, snow and ice can lead to power outages and make travel conditions dangerous.

Have non-perishable food and bottled water on hand. (If you have electric appliances, plan meals that can be eaten without using the stove or oven.) Make sure you have enough winter clothing and blankets to stay warm if power goes out. Keep your cellphone charged and have flashlights ready.

Keep an emergency supply kit in vehicles. Be prepared if you have to drive in icy road conditions. (If you hit black ice while driving, take your foot off the pedals and steer into the skid.)

Bring pets inside and make sure animals that can’t be brought in have access to lots of food and water that isn’t frozen.

Check on elderly relatives, friends and neighbors.
