San Antonio, Texas – A stretch of dangerous heat continues in South-Central Texas as temperatures climb to near 100°F this week, with heat index values pushing 105°F in San Antonio. The National Weather Service warns that isolated afternoon thunderstorms could develop from Monday through midweek, bringing brief downpours and gusty winds.
