Triple-Digit Heat Index Grips Austin; Showers Possible by Weekend

Austin is preparing for a week filled with bright sunshine and soaring temperatures, as the National Weather Service (NWS) predicts a series of triple-digit heat index readings and scant relief during the night hours. 

Throughout the week, conditions will remain predominantly dry and hot, but as the week progresses, there may be a slight chance of rain—providing residents with a possible break from the intense heat.

Sunday kicks off with predominantly clear skies and a high temperature approaching 95°F, although the heat index may climb to 102°F, as reported by the NWS. Light winds from the south-southeast at 5 mph are expected to provide slight comfort, with overnight temperatures dropping to approximately 77°F.

Monday begins with overcast conditions, but expect a transition to clear skies by the afternoon, bringing bright sunshine and temperatures soaring to around 97°F. Gentle breezes are expected to persist, with only minor fluctuations, while nighttime temperatures are anticipated to drop to 75°F under predominantly clear skies.

Tuesday signals the start of the week’s hottest days, with temperatures soaring to around 98°F under clear, sunny skies. Expect clear skies to persist into the evening, with overnight temperatures dipping to around 73°F.

The heat is set to escalate by Wednesday, with temperatures potentially hitting 99°F, alongside persistent “sunny and hot” weather conditions. A change in wind direction will usher in a gentle south breeze at five mph by evening, accompanied by partly cloudy skies and temperatures dipping to around 76°F.

The trend of hot, dry conditions continues through Thursday, with “mostly sunny” skies maintaining temperatures around 98°F. The evening is expected to feature partly cloudy skies, with temperatures dipping to around 78°F.

As we approach Friday, expect a notable change in weather patterns. The NWS forecasts a 20% likelihood of showers and thunderstorms, while the majority of the day is expected to be “mostly sunny” with temperatures reaching around 97°F. This represents the first significant shift in the ongoing dry conditions of the week, though it does not ensure a change.

As we approach Saturday, the outlook indicates a 30% likelihood of showers and thunderstorms, suggesting a slight yet welcome opportunity for rain. Expect temperatures to soar to 96°F, with bright sunshine dominating the day.

The heat of summer is nothing new to Central Texas residents. However, the upcoming days present a unique challenge: clear skies, high humidity, and little to no wind, resulting in an especially oppressive atmosphere. 

The National Weather Service continues to remind residents to stay hydrated, limit outdoor activities during peak heat hours, and monitor weather alerts, particularly with the possibility of thunderstorms this weekend.
