Austin weather: 10th triple-digit day in a row; heat alerts in effect
AUSTIN, Texas - It may be a new day and week, but it's the same weather story with triple digit heat.
What can I expect from the weather today?
Timeline:
Most of the area is under either a Heat Advisory or an Extreme Heat Warning.
The heat warning will be downgraded to a heat advisory tonight and will stay that way through Wednesday.
By the numbers:
We are talking about being in the 100s for 4 to 6 straight hours today as the high flirts with the record high of 107. The last time we saw temperatures on Aug. 24 was way back in 2010.
While the humidity is lower and this will be a dry heat, it is still dangerous.
This will be the tenth day in a row of triple-digit temperatures, and the 27th of this whole summer.
Heat advisories, warnings today
Big picture view:
Multiple counties are under an Extreme Heat Warning until 7 p.m. tonight (Aug. 24):
- Bastrop

- Travis
- Williamson
These counties will also be under a Heat Advisory through Wednesday night (Aug. 26).
Bell, Lampasas, and Milam counties will be under the Extreme Heat Warning until 9 p.m. tonight (Aug. 24).
What's next:
The heat dome will slowly weaken to bring us below heat alert criteria and also open the door to low rain chances.
A weak front will try to sag south into Texas Thursday and Friday to help take the edge off the heat briefly.
What's the difference between a heat advisory and a heat warning?
Dig deeper:
A Heat Advisory is triggered when the heat index hits at least 108 degrees or the air temperature hits at least 103 degrees.
An Excessive Heat Warning is then triggered when the heat index hits at least 113 degrees or the air temperature is at least 105 degrees.
