The people who had sheltered at the school had decided the danger was over about a half hour before it hit, and had gone home. The NWS had indeed cancelled a tornado warning about 45 minutes before this hit.
There were 2 and maybe 3 tornadoes in my county that night. This one in the video came over my farm as a cyclonic storm. We had already lost lights an hour and half beforehand, due to just severe storms. The sky was continuously lit by lightning for about 1-1/2 hours.
As it passed, my electronic wind speed gauge read 27 mph continuous with gusts off the scale. The wooden power pole in my farm's side yard began to whip back and forth like a tree trunk, about a foot either way, as the storm passed. I had never seen it do that in 23 years. As it passed, in typical cyclonic fashion, the winds changed direction from west to east. I lost trees, including a 300-year-old oak.
I wish I had thought to do a video or stills, but I wasn't exactly focused on photos at that time!
Once it passed us, it crossed a 100-acre wheat field that is immediately across the street to the east, then crossed the road that borders the back of that field, then it touched down as an F-3 and started to do its damage.
This is definitely in my Top 5 storms I have experienced.
Some of you might recall I posted 2013 pix of another near-tornado that passed over my farm on the same track, but then instead of forming up it fell apart shortly after. I added the photos back in at the end of the old thread:

This was definitely much stronger and the real deal. We are extremely fortunate and I will be using the chainsaw on Saturday.
The saddest part about the school is that when you look at the damage, it was not a well-built building and they already have announced they will use the same local contractors to rebuild it just as it was. I am so glad I do not have children going there.
