SAN ANTONIO – The severe, record setting storm event is over, but the rain chances aren’t, KSAT Meteorologist Mike Osterhage said.

Storms began to develop late yesterday afternoon along the Rio Grande and quickly grew to become severe. There were numerous reports of high winds and large hail with some as big as softballs. Tornado warnings were along the US 90 corridor from Uvalde county through Medina and into Bexar County. Some rainfall estimates showed widespread 4″-5″. 2.55″ fell at San Antonio International Airport yesterday which was a new, daily record... and the highest daily amount since October of 2019.

The National Weather Service will send teams out to various locations to examine the damage and debris, and determine if it was caused by strong winds or tornadoes, and the strength.

There is another upper low which will move into our area tomorrow and bring more rain late in the day and through Saturday. Temperatures will stay in the mid 70s. Sunday we’ll see more sunshine and get into the mid 80s.

Next week will start out hot, low to mid 90s, then another shot at some rain Tuesday.
