If you stepped outside this morning and felt an icy chill you weren’t expecting, you’re not alone. A powerful Arctic air mass has pushed deep into Texas, bringing the coldest temperatures of the season and the looming threat of freezing rain that could make roads dangerously slick.
This sudden freeze has prompted a Cold Weather Advisory for San Antonio, as temperatures are struggling to rise above the mid-30s. Meteorologists warn that light precipitation late Friday into Saturday morning could turn into freezing rain or drizzle, making roads—especially bridges and overpasses—incredibly hazardous.
How Cold Will It Get in San Antonio?
- Friday, February 21: The city will remain cloudy and bitterly cold, with temperatures only reaching a high of 38°F (3°C). A 20% chance of freezing rain develops by late evening, and overnight temperatures will drop to 33°F (1°C)—just cold enough for icy conditions to develop.
- Saturday, February 22: Another frigid and cloudy day, with temperatures reaching 41°F (5°C). Rain chances increase to 40-50%, with the biggest risk of early morning slick roads due to leftover freezing rain. Lows will be around 37°F (3°C).
- Sunday, February 23: A dramatic shift begins, with clouds breaking for sunshine and temperatures jumping to 66°F (19°C). The icy blast will be over, but the quick warm-up could cause lingering moisture to create dense morning fog.
- Monday, February 24: A major warm-up! Temperatures soar to 78°F (26°C) under partly sunny skies. The low will be a comfortable 45°F (7°C).
- Tuesday, February 25: Sunshine returns, with a high of 78°F (26°C) and a low of 56°F (13°C).
- Wednesday, February 26: Another pleasant and warm day, with a high of 78°F (26°C) and a low of 51°F (10°C).
What’s Causing This Arctic Chill in Texas?
This brutal cold is part of a massive Arctic outbreak that has plunged over 230 million Americans into freezing temperatures. From Montana down to Texas and stretching east to Florida, the icy grip of this system has sent temperatures plummeting to record-breaking lows.
Some areas in the northern U.S. are experiencing wind chills as low as -51°F (-46°C), and cities like Kansas City, Omaha, and Des Moines have reported wind chills below -20°F (-29°C). Even parts of the Gulf Coast and South Texas are experiencing an unusual deep freeze, with temperatures in the 20s and 30s.
San Antonio is no stranger to cold snaps, but this kind of Arctic blast is rare, especially with the added threat of freezing rain. The good news? The warm-up is coming soon.
How to Stay Safe During This Cold Snap
- Dress for extreme cold – The wind and damp air will make it feel even colder. Wear thick layers, gloves, and hats to stay warm.
- Be careful on the roads – Icy spots are most likely on bridges, overpasses, and less-traveled roads. If you must drive, use extreme caution.
- Protect your pipes – With temperatures hovering near freezing, pipes could freeze and burst. Let faucets drip slightly to prevent damage.
- Check on vulnerable neighbors and pets – Make sure elderly residents and outdoor animals have warm shelter.
When Will San Antonio Warm Up?
The bitter cold will ease by Sunday, with temperatures making a dramatic comeback into the mid-60s. By Monday and Tuesday, highs will reach the upper 70s—a nearly 40-degree temperature swing in just a few days!
However, this rapid warm-up could lead to some unstable weather later in the week, so stay updated on the latest forecasts.
