San Antonio, TX – Texans are waking to a crisp, calm Thursday morning under clear skies, with a chilly 44°F start and light winds brushing from the north. The air feels fresh, the kind that makes morning coffee steam a little longer on patios across Bexar County. By late morning, sunshine will dominate as the chill eases into comfortable mid-70s warmth — perfect for any last-minute Halloween decorating or evening strolls.

According to the National Weather Service in Austin/San Antonio, dry air and light winds will keep skies clear through the weekend. Daytime highs are expected to rise slightly each day, reaching near 78°F by Saturday. Nights will stay cool, dipping into the upper 40s to low 50s, ideal for trick-or-treating or late-night outdoor plans.

As November begins, forecasters see signs of a pattern shift across the country. Colder air is building in the northern U.S., and long-range models hint that parts of the Midwest, Great Lakes, and Northeast could see their first measurable snow between November 8–21. For Texas, the weekend remains mild and dry, but a cooler trend could reemerge by mid-month as upper-level systems push south.

For now, expect a classic fall feel — crisp mornings, golden afternoons, and calm evenings. It’s a quiet start to November, but the nation’s first true winter waves aren’t far behind.
