Austin, Texas – South-Central Texas continues to sizzle under seasonally hot skies this Sunday, with temperatures soaring into the lower 100s across the Rio Grande Plains and upper 80s in parts of the Hill Country. Light sprinkles are possible across northern areas late this afternoon, but the primary concern remains elevated heat index values, which could top 105°F in cities like San Antonio, Del Rio, and Uvalde.
According to the National Weather Service in Austin-San Antonio, high temperatures will range from 88°F in Fredericksburg to 102°F in Cotulla. South to southeast winds will bring occasional gusts, offering only brief relief. A slight chance of light rain may develop northeast of Austin late Sunday, but measurable accumulation is unlikely.
Heat safety remains crucial. Residents are urged to limit outdoor activities, stay hydrated, and check on vulnerable individuals. Expect similar conditions through midweek, with maximum temperatures holding steady in the upper 90s to near 100°F across the region.
Rain chances increase slightly next weekend, especially in eastern counties, as a modest shift in the pattern brings a hint of cooling. Still, daytime highs will hover in the mid-90s.
