The most intense heat dome of the year — resulting from a strong high pressure system in the upper-levels of the atmosphere — continues to sit over much of Texas. In San Antonio, temperatures have risen to at least 100 degrees in seven consecutive days, the longest streak San Antonio has recorded since 2024.
By the middle of this week, the area of high atmospheric pressure is expected to shift slightly to the west. Even so, this shift won’t change temperatures much, as triple-digit heat is likely to persist through the upcoming work week. So when will temps finally cool down? Here’s a look at what’s coming next.
Monday’s forecast
Monday will start quietly and comfortably, with temperatures likely hovering near 78 degrees between 5 and 8 a.m. But with mostly sunny skies expected throughout the morning, temperatures will rise quickly, likely reaching 90 degrees by 11 a.m.
Afternoon high temperatures are expected to reach around 102 degrees in San Antonio. This will come very close to the record high temperature for Aug. 24, which is 103 degrees set back in 2013. Skies will be sunny throughout the day and winds will be light, coming in from the south at 10 mph.
The humidity will cause conditions to feel even warmer, as heat index values will climb to between 105 and 107 degrees.
Triple-digits continue
San Antonio’s weather will stay rather consistent through the middle of the week. On Tuesday and Wednesday, high temperatures are expected to reach near 102 degrees each day, with morning low temps expected in the upper 70s. Rain chances will also stay slim to none through much of the state…
