Texas – Warm air lingers across south-central Texas this morning, but it won’t last. Clouds thin, winds turn brisk, and a colder edge creeps in as the day unfolds. Jackets may come off this afternoon, then head right back on by nightfall.
According to the National Weather Service office serving Austin and San Antonio, a reinforcing cold front slides through today, setting up a noticeable temperature drop into the weekend. Afternoon highs still reach the upper 50s, but north winds increase and pull colder air south by evening.
Tonight clears quickly. Temperatures fall into the mid-30s, and calmer skies allow heat to escape fast. By Saturday morning, the city wakes to crisp air and bright sun, with highs only near 49 degrees. Gusts out of the northeast may push wind chills lower during early outdoor activities.
Saturday night brings the coldest stretch. Lows dip to around 26 degrees, cold enough to impact pets, exposed pipes, and sensitive plants across Bexar County. Residents should plan now to protect outdoor plumbing and bring animals indoors.
Sunday rebounds nicely under full sunshine. Highs climb back to the mid-50s, offering a comfortable but cool winter day. Mornings remain chilly, especially in shaded neighborhoods and low-lying areas.
By Monday, warmer air returns quickly. Afternoon temperatures surge into the mid-60s, with light southerly winds restoring a springlike feel. The warming trend continues into early next week, though clouds increase and rain chances creep back by Tuesday night.
Drivers should watch for slick spots early Saturday morning where condensation or leftover moisture freezes briefly. It’s a classic flash-freeze setup for this time of year.
The bigger takeaway: enjoy today’s mild weather, but prepare for a fast cooldown. Layers will matter again before the weekend ends. How cold did it feel where you stepped outside this morning?
