Some storms could redevelop late overnight and could produce heavy downpours. Your best bet is to stay weather aware all, keeping the KSAT Weather Authority app and radar handy.
SUNDAY & MONDAY
For those with outdoor plans this Memorial Day weekend, we do expect quieter conditions on Sunday and Monday. Isolated activity will remain possible, but will be driven by afternoon heating. Rain chances Sunday sit at 30%, while lower odds are expected on Memorial Day.
