Multiple rounds of storms are expected to strike south-central Texas through the weekend, according to the National Weather Service.

Severe thunderstorms were expected as early as Thursday afternoon and continue through the evening, mainly along and west of the I-35 corridor. Severe weather is expected to continue Friday morning and possibly Friday afternoon as well, according to NWS.

The main threat associated with the storms was hail, which NWS said could reach up to 2 inches in diameter. Damaging wind and heavy rain were also possible with the storms.

Although the threat of severe weather is diminished after Friday, a cold front passage is expected to bring more heavy rainfall over the weekend, with a potential for flash flooding.

NWS said that they expect rainfall as early as Saturday morning and to persist through Sunday evening, with up to 3 inches expected and 4-5 inches in some areas north and northwest of San Antonio.
