San Antonio, get ready for a dramatic weather shift that will have you reaching for both sunscreen and a jacket within days! The city is about to experience a rollercoaster of temperatures, starting with summer-like heat in the mid-80s, followed by powerful winds and a strong cold front that will send temperatures tumbling by Sunday. If that wasn’t enough, the incoming dry air and high winds are setting the stage for increased wildfire danger, making this one of the most unpredictable weekends of the season.
Right now, conditions seem calm with mostly clear skies and temperatures sitting at 50°F (10°C), but that’s all about to change. Let’s break down what’s coming.
What’s About to Happen with San Antonio’s Weather?
The next few days will bring rapid changes, so don’t be fooled by the current mild conditions.
- Thursday: A mostly sunny and warm day with highs reaching 81°F (27°C). The wind will start picking up in the afternoon, with gusts possibly exceeding 30 mph.
- Friday: The heat cranks up even more, with temperatures soaring into the mid-80s, nearly 15 degrees above normal for this time of year. Expect morning fog, which could impact your commute, so plan accordingly.
- Saturday: This is when things start to take a turn. A Pacific cold front moves in, bringing strong winds of 15-25 mph, with gusts up to 40 mph. The biggest concern? Dry air combined with these winds will create a high fire danger.
- Sunday: Get ready for a major temperature drop! Highs will only reach the mid-60s, and brisk northerly winds will make it feel even cooler. Morning lows could dip into the mid-40s, a sharp contrast from the heat just days earlier.
Why This Weather Shift Matters
This kind of extreme weather swing isn’t unusual for Texas, but it does come with risks. The strong winds on Saturday won’t just make it feel blustery—they can make driving difficult, especially on highways and open roads. Vehicles with high profiles, like trucks and SUVs, are especially vulnerable.
Even more concerning is the elevated wildfire risk. With dry air moving in and gusty winds expected, any small spark could quickly turn into a dangerous situation. Authorities are urging residents to avoid outdoor burning and exercise caution with anything that could ignite a fire, such as grilling, discarded cigarettes, or using machinery near dry grass.
By Sunday, the cooler temperatures will be a relief from the heat, but the lingering wind could still pose minor issues, especially in the early morning hours.
How to Stay Safe and Prepare for the Weekend Weather
- Secure Loose Outdoor Items: Strong winds could send patio furniture, trash cans, and decorations flying. Either bring them inside or tie them down.
- Plan for Changing Temperatures: If you’ll be outdoors this weekend, dress in layers to handle both the warmth and the cooler air moving in.
- Be Extra Cautious on the Roads: High winds can make driving hazardous, especially on highways. Keep both hands on the wheel and avoid sudden lane changes.
- Take Fire Safety Seriously: The dry, windy conditions increase wildfire risk, so avoid outdoor burning and be mindful of any heat sources that could start a fire.
- Check the Forecast Frequently: Texas weather can change quickly. Stay updated with the latest forecasts so you’re not caught off guard.
Final Thoughts
San Antonio is in for a wild weekend of weather, with warm temperatures giving way to a powerful cold front, gusty winds, and an increased wildfire threat. The biggest dangers will come from strong winds on Saturday and Sunday, which could make driving risky and increase fire hazards across the region.
While the heat will make Friday feel like a springtime scorcher, by Sunday, you’ll be reaching for a light jacket as temperatures drop into the 60s. It’s a classic case of Texas weather whiplash, so make sure you’re prepared for anything.
