What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

A narrow, fast-moving, tornado began in the parking lot of a business along Howard Blvd where it tipped over a semi trailer and proceeded to cause roof, siding, fence, and tree damage. Approximately one block later, it caused the worst damage of the entire track where an attached garage and entire roof were removed from a ranch home. Much of the roof was deposited 20 to 100 yards downstream. The tornado proceeded to produce sporadic damage over the next two blocks and then a more consistent damage path for a 6 block period where many homes had minor to moderate roof damage and several trees were snapped or uprooted. There was then another 5 blocks of sporadic minor to moderate tree and roof damage followed by a 2 block stretch of continuous minor to moderate roof and siding damage. The tornado then travelled across open fields until reaching the Indian Hills neighborhood where it snapped two power poles and caused generally minor damage to a fence and shingles, with no further damage downstream. The entire 2.7 mile track occurred in approximately 2 minutes.

The wider storm

A low pressure system brought strong (both thunderstorm, and non-thunderstorm) winds, tornadoes, dust, snow, and record temperatures into eastern Nebraska and western Iowa. The event was determined to be a derecho meeting the criteria of wind damage extending more than 250 miles, including wind gusts of at least 58 mph and numerous gusts of at least 75 mph.

Began near Columbus (41.4400, -97.3800).
