DES MOINES, Iowa (AP) – A broad-scale mesoscale convection vortex (MCV) moved across south central and central Iowa early Sunday morning.  An assessment by the National Weather Service in Des Moines, determined along the track of the MCV, the circulation produced a broad swath of damaging straight line thunderstorm winds from Decatur to Boone County. The winds resulted in the derailment of a Burlington Northern Sante Fe train, with over 80 railcars being blown off the tracks 4.0 miles west of Osceola. Other tree and structural damage occurred to outbuildings in the same area.

Winds across the region were estimated to average 60 to 70 mph with higher embedded Gusts of 70 mph to 80 mph. The large MCV then progressed nearly due north producing other straight line wind damage along a line from west of Truro to west of St. Charles north toward Adel, Bouton, and into Boone County. Several farm structures were damaged and trees uprooted. Winds in the area reached around 70 mph at times in the hardest hit areas.

The storms also dropped roughly 2 inches of rain in Ringgold and Humboldt counties.

DES MOINES, Iowa (AP) — Strong storms damaged farm buildings across central Iowa, knocked down trees and toppled dozens of empty railcars. The storms caused damage in Decatur, Clarke, Dallas, Boone and Madison counties as it moved across the state early Sunday morning.
