San Antonio is starting Saturday, September 19, with temperatures in the 70s and possible stratus, though that would not amount to a real cooldown. The forecast calls for mostly sunny skies by afternoon, a high near 97, and heat indices that may exceed 100 degrees in parts of the region as summer keeps refusing to read the calendar.
East-southeasterly winds should stay below 10 knots, with no rain expected today. The National Weather Service forecast puts tonight’s low near 75. Peak afternoon heat indices may exceed 100 degrees.
The latest outlook is a substantive update to Friday’s forecast, with San Antonio now expected to stay dry through Sunday afternoon. The persistent heat also continues the pattern outlined in Hoodline’s previous report.
Sunday Stays Hot With Little Rain
Sunday should bring mostly sunny skies and another high near 97, with heat indices potentially exceeding 100 degrees in parts of the region. Overnight lows will remain in the mid-70s, so relief after sunset will be limited.
Next Week Looks More Like Summer
Monday reaches the mid- to upper-90s, followed by mid- to upper-90s Tuesday through Thursday and mid- to upper-90s Friday. Rain chances remain low overall, though they could reach 25 percent in parts of the region during the workweek.
Most of the week should stay dry, and no watches, warnings or advisories are listed for the San Antonio area. Anyone heading outside should plan strenuous activity for the morning or evening, carry water and take regular breaks from the afternoon heat.
