Scary Morning Weather!

This morning I let my dogs back in, it had been overcast since yesterday. Less than 10 minutes later, it became extremely dark outside. Seconds later it began pouring like I haven't seen in years, literally like a giant tank overturned above our house. Then, the sound. I looked outside to see this:

Hail!
I cringed as I thought would've happened if my dogs would've been outside, a mini Dachshund and a Chihuahua vs. dime to quarter sized hail. Luck was on their side today.
