Many areas in Mississippi could get snow early next week, paired with days of subfreezing temperatures and some overnight lows in the teens, according to National Weather Service forecasts. Here’s what we know.

A system will bring rain and snow to many parts of the U.S. through the weekend, and it will push a blast of Artic air into the South that’s expected to stay for a few days into the middle of next week.

The NWS is calling for a major Arctic air outbreak that will affect the Great Plains to east of the Appalachian mountains and as far south as the Gulf of Mexico. Areas to the north can expect subzero temps. AccuWeather meteorologists said the air from Siberia will cause some of the coldest lows seen so far this winter.

Current predictions also call for rain Saturday. According to NWS forecasts, several parts of the state have a chance of snow on Monday and/or Tuesday. Some areas can expect the extended cold snap to bring overnight lows in the teens and daytime highs below freezing.

Why does it keep getting so cold?

According to the University Corporation for Atmospheric Research, which manages the U.S. National Science Foundation National Center for Atmospheric Research, polar air comes south sometimes where the polar jet stream wanders.

As they describe it, the polar vortex circles the north pole counterclockwise. the polar jet stream circles at a lower level of the atmosphere, which usually keeps Arctic air corralled in the middle.

When the polar vortex is weak, the jet stream pattern wanders around a bit instead of staying in place “like a toupee that goes askew.”

The scientists that make up UCAR say predicting the pattern is getting harder because the Arctic is warming at a rapid rate.

How can I prepare for extreme cold?

The National Weather Service has tips to protect your family, pets, home and more in extreme cold.

Family

• Know your weather forecasts, be ready in case of power outages.
• Limit time outside in the cold. Early morning is the coldest, and kids might need to wait for the school bus somewhere warmer than usual.
• Dress for winter weather, including layers to keep out the wind and wet. Wear waterproof boots, a hat and gloves.
• Get a kit together for your home and/or vehicle.
• Don’t stay in wet clothes, stay warm and dry.
• Check on elderly relatives, friends and neighbors.

House

• Insulate pipes.
• Drip water and open cabinet doors to let pipes get warm air circulation.
• Turn off sprinklers, and disconnect hoses. Insulate outside taps and pipes.
• Winterize the home, like checking your chimney, clearing gutters. Insulate windows and attics if possible. If there are gaps around blankets or doors you can’t fill, cover them with blankets or towels.
• Install/check smoke alarms and carbon monoxide detectors.
• If you have a generator or plan to use one, make sure it’s set up to run safely to avoid carbon monoxide poisoning. Don’t run it in the house or near air intake for the residence.
• Use space heaters safely: don’t leave them unattended and be sure there’s a 3-foot space away from flammable objects like curtains or furniture.
• Close unused rooms to keep from wasting heat.

Car

• Make sure your vehicles have at least half a tank of gas so you can stay warm if stranded.
• Have an emergency kit ready in your car if you have to travel in cold weather.

Pets

• If pets can come into the home or another shelter, bring them in.
• If animals, like livestock, can’t come inside, try to provide shelter and make sure their water isn’t frozen over regularly.

What should I have in my emergency kit?

According to the NWS, people should have the following in emergency kits for their homes and vehicles.

To be ready for emergencies have:

• Flashlights with fresh batteries.
• Spare batteries.
• First aid kit and any medicines or medical supplies you need.
• Backup clothes for winter weather.
• Baby gear.
• Food that’s non-perishable and/or will not have to be cooked if you lose power. If you pack canned good, be sure you have a manual can opener.
• Water (plan 1 gallon per person for 3 days).
• Pet supplies (food and water).
• A basic toolkit, including pliers, a wrench, and a screwdriver.
• A radio.
• Warmers.

Car kits need a lot of the same items and few others, including:

• Jumper cables.
• Cat litter or sand for tire traction.
• Shovel.
• Ice scraper.
• Roadside emergency kit.
• Blankets/sleeping bag.

How low can I set my thermostat?

The World Health Organization recommends a minimum temperature of 68 degrees for children, people with health problems and the elderly. WHO advises a range between 64 and 75 degrees for healthy people.

Thinking of going without heat and powering through with warm winter layers?

According to the CDC, hypothermia, or a dangerously low body temperature, usually happens in extreme cold but can happen in temperatures over 40 degrees if a person gets chilled from rain, sweat or cold water. A person can lose body heat faster than they generate more, leading to confusion and affecting their ability to move.

Babies sleeping in cold bedrooms can get hypothermia, as can elderly adults who don’t have enough food, clothes or heating.

Can I use my oven to heat my house?

No. Ovens aren’t made for space heating, making them inefficient for the job, which leads to increased fire risk.

Electric ovens don’t post a risk for carbon monoxide poisoning, but gas ovens do, and the Centers for Disease Control and Prevention advises against it.

Can I get help paying my power bill?

Mississippi Power has multiple programs to help people facing economic hardship, the elderly and people with disabilities pay their bills.
