Happened about a year ago.
Was at my office, TVs started their warning alerts for tornado. Didn't appear to be a problem in our immediate area per radar. Raining hard, lots of lightning, sky looked greenish. Then it seemed to let up.
My receptionist looked out the window to the east of our office and spotted the tornado. She ran outside and snapped this pic on her phone. The funnel was about 1/2 mile away from us.
Thankfully, no damage, but it did give us all shivers. There was damage down the road to some farms.
