Key takeaway Expect sunshine and highs near 100° by late week, with heat index values in the low 100s.
Why this matters in The San Antonio
As the dry and quiet weather pattern holds, San Antonio residents can expect a return to typical summer heat by the end of the week. The forecasted highs near 100° will likely exacerbate the already persisting river flooding along the San Antonio River basin, as floodwaters continue to move downstream. Downstream residents should remain vigilant and monitor conditions closely to avoid flooded roads and crossings. The recharging of the Edwards Aquifer, however, is a welcome development, as runoff flows into local watersheds and lake levels rise. This bodes well for the city's water supply, particularly as Medina and Canyon Lake levels are expected to stabilize after rising. With the heat index values approaching 100°, residents are advised to take necessary precautions to stay cool and safe, especially in areas where flooding may still be a concern.
