Austin Faces Extreme Heat with Possible Rain Relief Later in the Week Amid Hurricane Activity
Austin is bracing for sweltering temperatures as another day of extreme heat is upon the city, with a forecasted high of 100 degrees Fahrenheit on Sunday. This marks the 14th instance of triple-digit heat this year, exacerbating the challenges faced by local residents.
While a brief, spotty rainfall was observed on Saturday, it offered minimal respite from the oppressive conditions. Humidity levels are expected to remain high throughout the day, pushing the “feels like” temperature up to 106 degrees in specific areas. Early Sunday morning, temperatures were already in the mid-to-high 70s, hinting at a hot day ahead.
As the week progresses, temperatures are doomed to climb back into the triple digits by Monday afternoon, with morning temperatures starting in the 70s. The likelihood of rainfall is low on Monday and Tuesday, but meteorologists predict an increase in rain chances by the week’s end, specifically peaking on Thursday. Expected rainfall accumulation could range between a quarter-inch and one inch during this period.
Active Hurricane and Weather Alerts
Complicating the weather situation is Major Hurricane Erin, which has recently fluctuated in intensity. Initially intensifying to a Category 5, it is presently weakening but is forecasted to regain strength, potentially reaching Category 4 status. Importantly, Hurricane Erin is not anticipated to make landfall in the U.S., though it is expected to generate dangerous surf and rip currents along the East Coast.
Two additional disturbances in the Atlantic are also being monitored, with formation chances estimated at 20% and 10%, respectively. Given the current weather systems, the National Weather Service has issued a flood watch for the Texas Hill Country and the Interstate 35 corridor until 7 a.m. on Tuesday due to saturated ground conditions.
In response to storm runoff from the San Saba and upper Colorado Rivers, the Lower Colorado River Authority has decided to open at least two floodgates at Buchanan Dam. The Texas Hill Country is expected to experience continued rain and thunderstorms late Monday into Tuesday, with conditions likely spreading to the Interstate 35 corridor.
The Forecast Ahead
By Thursday and Friday, peak daytime temperatures may ease slightly to the mid-90s, although high humidity could make temperatures feel closer to 100 degrees. Forecast models suggest that a subtropical high-pressure system could lead to drying conditions across South and Central Texas from Wednesday through Friday.
A separate system of low pressure is emerging in the Gulf, potentially bringing heavy rainfall to northern Florida and the upper Texas Gulf Coast later this week. Interestingly, July 2025 is shaping up to be one of the wettest on record for Austin, with 5.7 inches of rain recorded so far, which is significantly higher than the average of less than an inch for the first half of the month.
