New Orleans is not known for its frigid winters, but this week, residents are feeling the bite of an unusually strong Arctic blast. Temperatures have plunged well below the seasonal norm, leaving many people bundled up in heavy coats—something rarely needed in the Big Easy.
But don’t get too used to the icy chill, because the city is about to experience a drastic warm-up. In just a matter of days, temperatures will soar by nearly 40 degrees, bringing back the kind of mild, comfortable weather New Orleans is famous for.
This extreme weather shift may come as a shock, but meteorologists say it’s all part of a battle between Arctic air and warm Gulf moisture. The result? A week of unpredictable, dramatic changes.
Why is New Orleans Experiencing Such a Drastic Temperature Swing?
The deep freeze gripping the city is due to a strong Arctic front that has pushed all the way down into the Deep South. This type of cold air mass is typically confined to the northern U.S., but when the jet stream dips unusually far south, it allows bitterly cold air to spill into states that rarely experience such extremes.
Here’s what’s happening:
- The Arctic air mass moved into Louisiana, sending temperatures plummeting below freezing overnight.
- Cold, dry conditions are making it feel even colder, with wind chills dropping temperatures into the 20s and 30s—a rarity for this time of year.
- By early next week, the jet stream will shift north, allowing warm air from the Gulf of Mexico to surge back in, pushing temperatures well into the 70s.
This kind of rapid temperature swing can be hard on the body, and it also poses risks for infrastructure, including frozen pipes, slippery roads, and potential flooding from melting frost.

By midweek, the city will be back to feeling like spring, and the recent Arctic chill will seem like a distant memory.

How This Wild Temperature Swing Could Affect You
1. Health Risks from the Cold Snap
Cold temperatures in a humid climate like New Orleans can feel much worse than the numbers suggest. Wind chills can make it feel below freezing, which can increase the risk of hypothermia and frostbite.
What to do:
- Layer up with warm clothing, including hats and gloves.
- Limit outdoor exposure, especially for children and the elderly.
- Be mindful of space heater safety—they are a leading cause of house fires during cold spells.
2. Bursting Pipes & Infrastructure Concerns
When temperatures drop below freezing, water pipes in older homes are at risk of bursting. As temperatures warm back up, the thawing process can cause leaks and flooding.
How to prevent this:
- Let faucets drip slightly to keep water flowing.
- Wrap exposed pipes to prevent freezing.
- Check for leaks after the warm-up to catch any issues early.
3. Increased Flooding Risks Next Week
As temperatures rise rapidly, melting frost and heavy rain on Sunday could lead to localized flooding. This is especially concerning for low-lying neighborhoods.
How to prepare:
- Clear drains and gutters to prevent water buildup.
- Avoid driving through flooded streets—just a few inches of water can disable a car.
- Stay alert for weather advisories in case of flash flood warnings.
Final Thoughts
New Orleans is no stranger to unpredictable weather, but this extreme temperature swing is one of the most dramatic shifts of the season. Residents should bundle up for the next few days, but get ready to shed those layers soon—because by next week, it’ll feel more like April than February.
So whether you’re hunkering down inside or planning an outdoor adventure next week, be prepared for wild changes ahead. The Big Easy’s weather is anything but predictable
