It was surreal. We took shelter at work for about an hour, but about 30 mins in some of us went into the hallway to take a look out the window; there was this massive wall cloud just hovering, and swirling. I'm pretty sure a whispered f-bomb escaped just before I hurried back into the room. We were very fortunate that nothing touched down in our immediate area.
Lancaster and Arlington were hit the hardest; please continue to keep those folks in your thoughts, prayers, etc.
