Austin, Texas – Blazing sunshine will turn Austin pavement into a heat trap today as temperatures reach 100 degrees. The heat index could hit 104, while repeated triple-digit afternoons keep Central Texas hot through Wednesday.
According to the National Weather Service Austin/San Antonio office, Austin reaches 100 today under sunny skies. Heat index values could climb as high as 104 degrees.
Camp Mabry reported 73 degrees before 8 a.m., but humidity was already 96%. That humid start will give way to intense afternoon heating.
Plan outdoor work, exercise and errands around the hottest afternoon hours. Carry water and take regular cooling breaks.
Sunday brings virtually no relief. Austin again reaches 100 degrees, with the heat index potentially touching 104. South winds remain around 5 mph during the afternoon.
Monday provides only a one-degree dip to 99. Tuesday rebounds to 100, followed by another 100-degree high Wednesday.
The persistence matters. Morning lows remain between 76 and 78 degrees, limiting recovery from the daytime heat.
Drivers on I-35, MoPac and U.S. 183 should prepare for punishing temperatures around parked vehicles and roadside stops. Check coolant and tire pressure before longer drives.
No rain or thunderstorms appear in Austin’s supplied five-day outlook. The national Weather Prediction Center discussion places significant heavy-rain and severe-storm concerns outside Central Texas during the short-range period.
The supplied local data also shows no specific tornado, hail or flooding signal through Wednesday.
Heat remains the clear public-safety concern. Never leave children or pets in a parked vehicle, even briefly.
Thursday climbs to 101 degrees. A 20% shower and thunderstorm chance appears Thursday night, followed by another 101-degree high Friday.
