My future plan is to refine these tracks farther, there is more evidence I am checking out. Plus, I am collecting as much media (photos etc.) as I can from county historical societies.

I will release the KML publicly once I feel it sufficient.

Maybe I will turn this into a broader re-analysis?

Some changes from official sources:

-Craig F-3 hit Turin
-Yutan F-4 hit Woodbine
-Small tornado southwest of Lincoln
-Greenwood track changed
-Omaha tornado began farther south in Sarpy County
-Council Bluffs tornado split in two/no evidence of any damage in Nebraska
-All the western Iowa stuff

I used the official tornado rating form Grazulis. The white is "EF-U". Some of these could also be downbursts, it's hard to distinguish in written accounts without any photos.

Western Iowa was the trickiest, with widespread damage across Crawford, Shelby, Carroll, and Audubon Counties.

I am not the first to attempt this, Trudy Bell did this back in 2007. I am just building on that.

Here is a comparison of the three maps including mine:

-NWS Omaha
-Trudy Bell
