FORECAST

After the spotty rain this morning, the rest of the day will be warm and humid.

A cool front will move through South Texas tonight. Storms will develop out ahead and along the front, peaking around midnight. It’s during this time that some storms could be strong to severe, although, widespread severe weather is not expected. Gusty winds and up to quarter sized hail would be the main threats. As with any storms, there’s a risk for localized power outages and pockets of heavy rain.

Around San Antonio, most locations should see about a quarter to half an inch of rain, but the luckiest neighborhoods could see 1 to 2 inches. Not much rain expected in the Hill Country.
