Nearly 60,000 people are expected to attend Southlake's Art in the Square this weekend, if the weather holds.
"We are here rain or shine," said Art in the Square chairperson Kris Nelson. "Safety first, of course, so if there's heavy winds and lightning, then we have a plan and places to go and take cover for that. Or, you know, go shop for a little bit and come back out."
A portable siren stands ready to sound if threatening weather approaches, warning people to take cover inside nearby buildings.
People can also sign up to receive text alerts.
