Est. Peak Winds	125 mph
Path Length	10.4 miles
Max Width	1 mile
Injuries/Deaths	0 / 0
Summary: A tornado touched down just south of Highway 275, damaging a home, power poles, and numerous trees as it entered the Elkhorn River valley. It caused EF-2 damage to a home just south of Elkhorn River where a porch was ripped off and large trees damaged. The tornado crossed the Elkhorn River where significant tree damage was noted and several center pivots were flipped over. The tornado became wider and impacted additional farmsteads, especially as it approached County Road F up to the Dodge and Burt county line. At these farmsteads, several hog barns, machine sheds, and well-built outbuildings were destroyed. Farm equipment was significantly damaged. Windows were broken out of homes, roofs damaged, porches ripped off and garage doors sucked out. Every person noted that their ears still hurt a day later due to the pressure drop during the tornado. Numerous livestock were injured or killed. The maximum width of this tornado approached one mile as it moved between County Road F and County Road B. A large cattle feedlot was impacted in extreme northeast Dodge County where very large grain bins and well-built barns were destroyed. This tornado exhibited multiple vortex damage patterns at times. The tornado appears to have dissipated just north of Country Road F in Burt County before developing a new tornado just to the north. Additionally, a satellite tornado was reported at the end of this tornado's life cycle.

Summary: This tornado started around 620 PM CDT near Burt County Road H, a little over 2 mil miles west of US 77 Highway. The tornado started moving north-northeast and then curved and was moving due north. As it moved north it gained strength and started destroying outbuildings and trees at various farmsteads, reaching EF-2 strength. By the time the tornado reached Burt County Road K, it became nearly ⅝ of a mile wide. Nearly a half-mile width of double-wide wooden transmission poles were snapped north of County Road L. The tornado, which was wrapped in rain, continued trekking to the north, damaging farmstead after farmstead, as well as uprooting and snapping trees. The tornado eventually weakened at 644 PM CDT, 3 miles west of Lyons. Two people were injured by the tornado. One had a tree fall on a shed with a person inside, injuring his head. The other person had cuts to his face from flying glass.

Summary: An intermittent tornado damage track was noted along the west flank of a focused and elongated area of downburst winds. The damage was largely to trees although there were a couple of farm outbuildings damaged along the track. One east-west oriented treeline had a focused damage area approximately 200 yards wide. It appears likely that this tornado track had some gaps in it based on the somewhat sporadic damage pattern.

Field terrace damage near Pisgah, Iowa	Road washout near Magnolia, Iowa	This culvert is one of two that was damaged during the heavy rain event. They are 14 feet in diameter and about 120 feet long.

Radar/MRMS


This is an image of CREST Unit Streamflow. This parameter, blue and white pixels, shows the significant runoff that occurred due to the heavy rainfall. For a rural area, seeing values like this are rare.	This is an image of how often this type of rainfall occurs on average. Values exceeding 10 are high. The value here are close to 100, which indicates an extreme rainfall event.	This is an image of the 3-hour rainfall as depicted by the radar. The values shown here indicated widespread rainfall amounts of 4 to 5 inches. It is likely even higher amounts fell than shown here.

River Hydrographs


A significant amount of runoff from the hills went into the Solider River. Note the river graph shows a more than 10 foot rise in a short period time due to this runoff.	Additional runoff from the hills even influenced the river level on the Missouri River. The gage at Omaha shows over a two foot rise in a short period of time due to this heavy rain coming out of Iowa.
