Are you sure the tornado initially touched down west of Colony?
I was maybe 2 miles south of town, looking in every direction... the mesocyclone was so high-based and flat that I thought instead I was seeing some sort of inflow tail stemming from an HP supercell. I couldn't see any signs of rotation when the lightning flashed. I guess it's possible it touched down as I ventured into the town and had my "back turned." That would explain how I somehow got through town without seeing the tornado (especially if it lifted while skirting the south side of town).
About halfway down the street through Colony, leaves (lots of them) were literally floating in the street. Then they began accelerating toward my car as stiff northeast winds picked up. I became alarmed and gunned it out of town, thinking this was inflow into a tornado behind me. In fact it was strong cyclonic flow on the back side of the tornadocyclone. (Just east of Colony I saw the tornado about 1 mile to my east-northeast.) Not my most shining moment as a chaser, but I was convinced I'd fallen well behind the meso when I first ventured into Colony due to the lack of structure.
