I hope (pray) that I'm correct in saying this, but just telling you what I saw on correlation coefficient (debris tracking product). It looks like Central Tupelo might have avoided a direct hit because the TDS stopped showing up as it crossed directly over the Central part of the City. The debris signature looked extremely dangerous on the SW and NE side of town, so I assume there will be a good bit of damage in those areas. Radar doesn't always tell the whole story so I could be wrong.
From the early reports, the damage seemed to be about a mile SE of the actual velocity signature on radar.
