Residents in Austin can expect to continue to bask in the warmth as the weather forecast predicts a week of consistent high temperatures close to the century mark. According to the National Weather Service, today's temperature will be sunny, with a high near 97. The warmth is accompanied by a southeast wind of around 5 mph. Evenings will offer some respite with anticipated lows around the mid-70s.

The pattern is set to persist throughout the weekend, clearly signaling an extension of the summer heat. On Saturday, the mercury is again expected to rise to a high of 96, with calm winds becoming south southeast around 5 mph in the afternoon. The night will partly cool down to a low of around 72. Austin's notorious heat seems to just linger, hardly allowing residents to fully embrace the usually anticipated fall temperatures.

As Sunday rolls in, the forecast doesn't veer off course. It's predicted to be mostly sunny with a high again nearing 96, and south winds picking up slightly at 5 mph in the afternoon. When night falls, skies will mostly clear up and temperatures will drop to a low around 71, with winds calming down post midnight.

Looking ahead to the new week, no significant change is in sight. Monday will welcome Austinites with a sunny sky and a high near 95, while the wind remains a gentle accomplice, becoming southeast around 5 mph in the afternoon. The nighttime sky will mostly be clear, hosting a low of around 71. This trend of heat and clarity seems to stubbornly persist further into the week, with the forecast for Tuesday showing more sunny spells and highs hovering around the mid-90s.

For those planning midweek activities, expect Wednesday to serve up more sunshine and a high of 96. The clear skies during the night should set the stage for stargazing, with temperatures dropping to a comfortable 72. And if anyone's betting on a break from the dry heat, don't place your wagers yet—Thursday promises another sunny day with highs standing steady at 96.
