HEATING UP

The heat really ramps up next week. A strong ridge of high pressure will bring a stretch of triple-digit temperatures, with the potential for some of the hottest weather of the year so far.

San Antonio International Airport has recorded just three 100-degree days this year, though other parts of the area have seen more.
