Texas – Late-day sunlight glints off dry pavement across San Antonio as a calm south breeze drifts through neighborhoods, hinting at another warm surge before a gentler cool snap shapes the Jan 17–18 weekend. Air feels crisp early, then warms quickly under a clear sky—classic mid-January Texas winter.
Temperatures climb toward the upper 60s today, and the breeze stays light and steady. By evening, skies clear completely and lows slip into the lower 40s. Drivers along I-35 will notice ideal visibility, though the quick evening cooldown may surprise anyone still dressed for mid-afternoon warmth.
Meteorologists now track a sharper wind shift arriving Friday. Sunshine pushes highs into the lower 70s, but west winds increase to near 10 mph before turning north in the afternoon. Gusts may reach 20 mph, adding a brief bite to an otherwise mild day. Plan to secure loose patio items before the shift.
Saturday turns cooler, with highs near 56°F under mostly sunny skies. Northwest winds increase again, gusting up to 20 mph. The air feels brisk at times, especially early in shaded spots where yesterday’s warmth quickly escapes. Conditions remain dry, so travel impacts stay low—for now.
Sunday brightens and stabilizes with a high near 59°F, though morning readings in the low 30s may produce patchy frost in rural pockets. Families heading to parks or morning services should dress in layers, as the chill fades slowly.
By Monday, sunshine returns and highs rebound into the mid-60s. A wetter pattern emerges later next week as the central U.S. grows unsettled, and long-range models hint at increasing Gulf moisture.
