FORECAST

STORMS POSSIBLE THIS EVENING

Temperatures have risen quickly this afternoon with 100 degrees nearly hitting for many. Heat indices have ranged from 102 to 115 with temperatures feeling much hotter south of San Antonio.

Rain showers and thunderstorms are developing across the Hill Country with lightning and strong wind gusts being the main threat. This activity is pushing south, but it is possible that Bexar County may not see as much rain activity as others. Make sure to briefly head inside should a storm move into your area. Activity is expected to fizzle out closer to 10 PM.

Average rain totals should remain below half an inch, though a few isolated spots could pick up an inch or more if a stronger storm moves overhead. Brief, localized street flooding & gusty winds cannot be ruled out, especially where heavier rain falls in a short period of time.

If you have Saturday evening plans, they can likely continue as scheduled. Just be prepared for a quick interruption indoors if a storm approaches.

DRIER AIR MOVES IN

A few leftover showers may linger early Sunday, mainly as the front continues pushing south. Skies will gradually clear through the day, and humidity levels will begin to drop. Temperatures will still be hot, with highs returning to the upper 90s and near 100 degrees. Thankfully, the drier air will make conditions feel slightly more comfortable compared to the muggy heat of the past week.

EXTENDED OUTLOOK

The weather pattern turns hot and dry again. Highs through next week are expected to remain near the upper 90s to low 100s, with warm mornings and lows generally in the mid to upper 70s.

Rain chances will be limited, so continue to stay hydrated, take breaks from the heat, and limit prolonged outdoor exposure during the hottest parts of the day.
