FORECAST

RAIN CHANCES HIGHEST FRIDAY NIGHT

Friday will start with low clouds and scattered sprinkles, then stray storms are possible by the afternoon. If anything happens to develop, it could quickly develop large hail and/or high wind gusts, so have an extra eye and ear to the sky tomorrow afternoon and evening.

The highest rain chances hold off until after sunset Friday night when scattered showers and storms are likely to develop. Again, some storms could become strong/severe. The highest accumulations will be in North Texas, but up to an inch is possible in the neighborhoods around San Antonio that happen to get storms.

WEEKEND BRINGS BIG COOL-DOWN, DIG OUT YOUR JACKETS

Scattered showers and storms should linger through about 9am Saturday with gradual clearing into Saturday afternoon. Temperatures will tumble over the weekend with highs in the lower 70s Saturday, and by Sunday morning, many of us will dip into the 40s - The Hill Country may even see 30s. It’ll be windy, too, with gusts from the north of up to 30-35 mph over the weekend.
