Texas – A cool, calm start greets San Antonio this morning, but the quiet air won’t last as a surge of early spring heat begins to build.
Temperatures begin in the upper 40s, with light winds and clear skies across the region. Roads along I-35 and Loop 410 remain dry, offering smooth travel through the morning commute.
By late morning, sunshine takes over completely. The air warms quickly, pushing highs near 79°F by afternoon. Light layers will feel unnecessary within hours.
This warming trend accelerates into late week. Meteorologists are tracking a strong ridge expanding east, driving temperatures well above normal. By Thursday, highs climb into the mid-80s under full sun.
Friday—the first official day of spring—brings a noticeable jump. Temperatures approach 89°F with bright skies and light winds. The heat will feel more like early summer than March.
The weekend intensifies the trend. Saturday reaches near 92°F, and Sunday pushes into the low 90s again. Afternoon heat may feel intense, especially for those spending extended time outdoors.
Plan ahead if traveling or working outside. Stay hydrated and take breaks during peak afternoon hours. Vehicles can heat up quickly under direct sun.
No rain is expected, and dry conditions dominate. While travel remains smooth, increasing warmth and dry air may elevate fire weather concerns across parts of South Texas.
