What happened
The episode as NWS DMX wrote it up.
The cold front mentioned above continued to move southeast into the state. As the thunderstorms that produced the hail over the northern part of the state during the evening hours weakened and moved east, another round of thunderstorms developed over west central Iowa. The storms produced high winds and hail. They formed into a scattered to broken line with numerous beta bow elements along the line. Initially the storms produced hail of up to an inch in diameter over west central Iowa. The event transformed into a wind event fairly early on. High winds swept into the Marshalltown area of Marshall County. A 195 foot radio tower collapsed in the wind. Considerable damage was reported in the area. Another example of wind damage came from Marion County as 60 to 70 MPH winds toppled trees and power lines in the area. Once again, crop damage was significant due to the condition of the tinder dry crop with reports of lodging received.
The radar
The Des Moines radar (KDMX), 123 km away, was scanning. The volume nearest the first event began at 05:49 UTC.
Event by event
