Winter Storm South US: Rare Snow, Ice on Texas, Florida

If you live in the southern United States, snow is usually something you see on TV — not in your front yard. But this week, a rare and powerful winter storm is sweeping across the region, blanketing states from Texas to Florida in snow and ice.

People affected: Over 150 million · States under warning: More than two dozen states from Texas to Maine · Blizzard warnings: Issued for parts of Texas and Florida · Flight cancellations: Thousands of flights delayed or canceled · Snowfall totals: Up to 12 inches in some southern areas

Six key facts from the snapshot, one pattern: the storm is historic in its breadth and intensity for the South.

Which states are affected by snow in the USA?

The storm corridor stretches from the Southern Plains through the Deep South and up the East Coast. Over 15 states are under winter weather alerts, and more than 150 million people are in the storm’s path (FOX Weather (weather news outlet)). Here’s the state-by-state breakdown.

Texas

• Blizzard warning in effect for parts of the Panhandle and West Texas (Central Florida Public Media (public radio station))
• Snow up to 10 inches in the Dallas-Fort Worth area (Roadtrippers (travel planning platform))
• Highways closed: I-10 east of Van Horn and I-20 east of Kent (Roadtrippers)
• Major airports in Houston, Dallas halted operations (YouTube broadcast (news coverage))

Florida

• Rare snow in northern parts, including the Panhandle (Central Florida Public Media)
• Freezing rain in central areas, state of emergency declared (FOX Weather)
• Blizzard warning issued for the western Panhandle (Central Florida Public Media)

Louisiana

• Ice storm warnings across the state (FOX Weather)
• Power outages reported in Baton Rouge and New Orleans area (Central Florida Public Media)
• Roads impassable in northern parishes (Roadtrippers)

Mississippi

• Heavy snow and sleet across the state (FOX Weather)
• Schools closed statewide in many districts (Roadtrippers)
• Travel strongly discouraged by authorities (Central Florida Public Media)

The implication: southern states that rarely see winter weather are now facing a multi-day crisis. Their roads, power grids, and emergency systems are being tested like never before.

What caused the rare winter storm in the southern US?

This storm is the result of a perfect alignment of atmospheric ingredients. The National Weather Service warned of a rapid intensification as Arctic air plunged southward (Central Florida Public Media (public radio station)).

Arctic blast

• A dip in the polar vortex pushed frigid air deep into the South (FOX Weather (weather news outlet))
• High temperatures below freezing for several days in areas unaccustomed to it (Roadtrippers (travel planning platform))

Jet stream pattern

• The jet stream amplified, allowing cold air to collide with warm, moist air from the Gulf of Mexico (FOX Weather)
• This collision produced heavy snow, sleet, and freezing rain (Central Florida Public Media)

Low pressure system

• A strong low-pressure system developed over the Southern Plains and intensified along the Gulf Coast (FOX Weather)
• The storm system rapidly deepened, leading to blizzard conditions and freezing precipitation (YouTube broadcast (news coverage))

The pattern: when Arctic air meets Gulf moisture over a bone-cold South, the result is a rare, high-impact winter event that the region’s infrastructure is not designed to handle.

How did the winter storm impact travel and infrastructure?

Travel across the southern United States ground to a halt as the storm brought snow and ice to areas unaccustomed to winter weather. More than 3,000 flights were canceled and major highways were closed (Roadtrippers (travel planning platform)).

Flight cancellations

• Major airports in Houston, Dallas, and Miami halted operations (YouTube broadcast (news coverage))
• Thousands of flights delayed or canceled across the region (Roadtrippers)

Road closures

• Interstate highways closed in multiple states: I-10, I-20, I-30, I-35, I-55, I-65, I-81, and I-95 sections affected (Roadtrippers)
• I-30 in its entirety and I-35 from San Antonio to Kansas City singled out for avoidance (Roadtrippers)

Power outages

• Over 15 states could experience power outages from ice accretion (FOX Weather (weather news outlet))
• The bull’s-eye for ice accumulation: East Texas through southern Arkansas (FOX Weather)
• Prolonged outages expected, with freezing rain weighing down trees and power lines (Central Florida Public Media (public radio station))

What precautions should residents take during a winter storm in the South?

If you live in the affected region, preparation is key. The National Weather Service recommends staying put and preparing your home for several days of extreme cold (Central Florida Public Media (public radio station)).

Stay indoors

• Avoid unnecessary travel; roads may be impassable (Roadtrippers (travel planning platform))
• If you must drive, carry an emergency kit with blankets, water, and a flashlight (FOX Weather (weather news outlet))

Winterize pipes

• Drip faucets to prevent freezing (Central Florida Public Media)
• Open cabinet doors to let warm air circulate around pipes (FOX Weather)

Emergency kit

• Stock up on flashlights, batteries, non-perishable food, and water (Roadtrippers)
• Keep mobile devices charged and have a battery-powered radio for updates (Central Florida Public Media)

Check on neighbors

• Elderly and vulnerable residents may need help preparing (FOX Weather)
• Protect pets and plants from freezing temperatures (Roadtrippers)

What is the forecast for the winter storm in the southern United States?

The storm peaked over January 23-24, but its effects will linger. Here’s what forecasters are tracking.

Timeline

• Storm developed over the southern Plains on January 22 (FOX Weather (weather news outlet))
• Peak impact on January 23-24: heavy snow, ice, and blizzard conditions (Roadtrippers (travel planning platform))
• Storm moves northeast by January 25; gradual improvement in the South (Central Florida Public Media (public radio station))

Expected snowfall

• Highest totals: over a foot from Nashville through western North Carolina (FOX Weather)
• Up to 12 inches in parts of Texas and Louisiana (Roadtrippers)

Duration

• Freezing temperatures expected to persist through early next week (Central Florida Public Media)
• Melting ice could lead to flooding later in the week (FOX Weather)

Ice accumulation

• Bull’s-eye for ice: East Texas through southern Arkansas (FOX Weather)
• Crippling ice expected across Georgia, South Carolina, and North Carolina (FOX Weather)

The implication: even after the snow stops, ice and cold will keep many areas paralyzed. Recovery will take days, not hours.

Timeline of the winter storm

• January 22 – Winter storm develops over the southern Plains; watches issued across Texas, Oklahoma, Arkansas (FOX Weather (weather news outlet))
• January 23 – Snow and ice expand across Texas, Louisiana, Mississippi, Alabama; blizzard warnings issued (Roadtrippers (travel planning platform))
• January 24 – Storm reaches Florida, Georgia, South Carolina; peak impact with heavy snow and freezing rain (Central Florida Public Media (public radio station))
• January 25 – Storm moves northeast; gradual improvement in the South (FOX Weather)

What this means: the window for intense winter weather in the southern states is roughly 72 hours long, but the aftermath will last much longer.
