Well, I only thought I heard thunder.
It was actually the explosion in West, TX.
I live over an hour north of West, TX and yes, I felt it. It was a huge boom and reminded me of the thunder I've experienced when a tornado is on it's way.
About 10 min. after posting, I realized it wasn't raining at all.
Turns out a Fertilizer Plant exploded.
15+ people were killed (as of now).
Homes were destroyed. Some no longer exist. The concrete pad is there, but the house is gone.
There was a middle school not too far away from the blast and it is destroyed as well. My school district is collecting school supplies for the students and teachers.
