Houston is about to experience a dramatic shift in temperatures as an intense Arctic front moves in, bringing freezing temperatures, gusty winds, and a heightened risk of icy conditions. The National Weather Service has issued a cold weather advisory, warning residents to prepare for some of the coldest air of the season.
This sudden change will catch many off guard, as Houston is currently enjoying mild temperatures in the upper 50s and low 60s. But don’t let the pleasant start to the week fool you—by midweek, temperatures will plummet into the 20s and 30s, making for a bitterly cold stretch that could last several days.
How Cold Will It Get? A Day-by-Day Breakdown
Tuesday, February 18 – The Cold Front Arrives
The day begins with cloudy skies and occasional light rain, but by the afternoon, a strong Arctic cold front will push through Houston. Temperatures will reach a high of 63°F (17°C) before plummeting to 38°F (3°C) overnight. Expect strong winds and rapidly falling temperatures in the evening, making it feel much colder.
Wednesday, February 19 – A Shocking Drop in Temperatures
Houston wakes up to a completely different climate. Cold air will grip the city, with daytime highs struggling to reach 45°F (7°C). Overnight lows will drop below freezing to 28°F (-2°C), making for the coldest night so far this year. The wind chill will make it feel even colder.
Thursday, February 20 – Cold and Cloudy
The chill continues, with temperatures barely rising throughout the day. A mix of sun and clouds will bring a high of 48°F (9°C), but once the sun sets, temperatures will dip to 31°F (-1°C), keeping Houston in a prolonged freeze.
Friday, February 21 – No Relief Yet
Even with slightly rising temperatures, it will still feel like winter in Texas. The high will be 41°F (5°C), with a low of 38°F (3°C). Cloud cover will make it feel colder than the thermometer reads.
Saturday, February 22 – A Slight Warm-Up with Possible Rain
Clouds will thicken, and scattered rain showers may develop, making the cold even more uncomfortable. The high will reach 50°F (10°C), and the low will stay around 40°F (4°C).
Sunday, February 23 – A Much-Needed Warm-Up
Finally, Houston will see some relief as temperatures climb back to 66°F (19°C). The sun will return, helping melt any ice that may have accumulated over the past few nights. However, residents should still be cautious of slick roads and lingering cold in the mornings.
How to Stay Safe During Houston’s Sudden Freeze
With temperatures set to drop below freezing, residents should take precautions to protect their homes, vehicles, and themselves from the extreme cold.
- Bundle Up – Even in Texas, frostbite can be a risk. Wear layers, gloves, hats, and scarves if you have to be outside for extended periods.
- Protect Your Pipes – Freezing temperatures can burst pipes, leading to costly damage. Let faucets drip and insulate exposed pipes to prevent freezing.
- Check on Elderly and Pets – The sudden cold can be dangerous for vulnerable individuals and animals. Make sure pets have a warm shelter, and check on elderly neighbors who may need assistance.
- Prepare for Icy Roads – Though no major snow or ice is forecasted, cold rain can lead to black ice on bridges and overpasses. If possible, avoid driving early in the morning when roads are most dangerous.
- Have Emergency Supplies Ready – Keep flashlights, extra blankets, non-perishable food, and bottled water on hand in case of power outages.
When Will Houston Warm Up Again?
The worst of the cold will last through Friday, but temperatures won’t fully recover until Sunday. Even after the warm-up, nighttime lows could still be chilly, so residents should stay prepared for colder mornings into next week.
This type of sudden Arctic front is rare for Houston, and while it won’t bring the extreme winter storms of past years, it will deliver a serious reminder that winter in Texas can be unpredictable.
