South‑Central Texas wakes up again under the grip of August heat, a pattern that refuses to budge as we move through the middle of the week. KNCT Meteorologist Bill Hecke set the tone early this morning, noting that skies began “generally clear” with a sustained southerly flow. Low stratus clouds will drift northward over the next couple of hours, briefly puffing into small cumulus as the day warms. But that’s the extent of our cloud cover. By late morning and afternoon, the sun takes full control again as moisture evaporates and skies open wide.
Temperatures start in the 70s and surge into the upper 90s and low triple digits, with heat index values near 105 degrees. South winds at 5–15 mph will strengthen to 10–15 mph, and gusts may reach 20–25 mph. It’s a combination that sharply increases the threat for grass fires across the region. Fire danger will remain elevated through the weekend, especially west of the I‑35 corridor where humidity and wind team up to create fast‑moving ignition conditions.
The National Weather Service echoes the concern. Their short‑range discussion highlights a sprawling heat dome stretching from the Central Plains to the Southeast, producing some of the hottest temperatures of the year. Many areas across the country will see heat indices between 105 and 115 degrees as humidity piles on top of triple‑digit heat . While Texas bakes, the western U.S. braces for a different story. A cooling trend, expanding showers, and even pockets of excessive rainfall capable of flash flooding. Montana may not escape the 60s today, marking its coolest stretch since June.
Here at home, the message is simple. Heat safety must stay at the top of your mind. Hydrate often. Take breaks in the shade. Protect your skin. And never leave children or pets unattended, always check that back seat.
Tonight brings partly to mostly clear skies with south‑to‑southeast winds at 10–15 mph and gusts up to 25 mph. Lows settle into the 70s, offering only modest relief before the next round of heat arrives.
Through early next week, South‑Central Texas remains locked in a pattern of daily highs from the upper 90s to near 103, with heat index values pushing 105–110 degrees. Austin and San Antonio will see widespread readings from the mid‑90s to near 104, with heat indices between 104 and 108 degrees. Fire danger will stay elevated each afternoon.
Across the nation, weather divides sharply. Dangerous heat dominating the central and southeastern states, while cooler air and storm activity reshape the West. But here in Texas, the story remains the same: hot, dry, breezy, and demanding respect.
