Grapevine businesses and homes damaged in tornado

Context: The NWS was expecting severe thunderstorms yesterday morning because of the humidity in the air, the wind shear and the arrival of a cold front, Dunn says.

• "It’s not completely uncommon to get tornadoes in December. Any time you get those ingredients together, it can happen any time of the year," he says.
• The weather service will continue surveying the damage to determine the strength of the tornadoes, and Dunn says there’s a chance more tornadoes will be confirmed from yesterday's storms.

Details: Five people were injured and several businesses, including Grapevine Mills Mall and Sam's Club, were damaged when one of the tornadoes touched down in Grapevine around 9:30am.

• Sam's Club was closed all day. A photo from inside the store showed a hole through the roof and debris in the middle section where the clothing usually is.

• Baylor Scott and White Medical Center — on the opposite side of the highway — was spared and its patients were safe, a spokesperson tells Axios.

Flashback: In December 2015, 11 people died and hundreds of homes were damaged when nine tornadoes touched down in North Texas.

What's next: The NWS expects the rest of the week to be quieter but colder, with lows in the 30s.
