Thunderstorm wind damage in Crawford County

News, Weather

May 24th, 2012 by Ric Hanson

Strong thunderstorms which crossed the Missouri River from Nebraska into western Iowa, Wednesday evening caused some minor tree damage in Crawford County. The National Weather Service said today (Thursday), a number of trees in a grove north of Ricketts where either downed, or lost large limbs, when estimated winds gusting up to 65-miles per hour blew through the area. The winds, which occurred at around 7:10-p.m, also caused the formation of a “gustnado,” a short-lived, low-level rotating cloud. They typically last for anywhere from a few seconds to a few minutes, and are often confused with tornados. The difference is, the rotating column of air does not extend upward, into the thunderstorm cloud base.

The storm also produced nickel-sized hail a few minutes after the winds occurred.

From the National Weather Service Offices in Des Moines & Valley, NE:

For Cass, Audubon, Crawford, Carroll and Guthrie Counties….Winds will increase out of the south today from 20-30 mph with gusts to near 45 at times. Thunderstorms will move into the area late this afternoon and tonight. Heavy rainfall is possible with some storms, which may also be severe. Large hail and damaging winds are the primary threat from these storms. An isolated tornado cannot be ruled out initially.

For Monona, Harrison, Shelby, Pottawattamie, Mills, Montgomery, Fremont & Page Counties…Thunderstorms are expected to develop after 3-p.mn. generally north of I-80, however the most likely area they will initially develop will be in northeast Nebraska. Throughout the evening, additional thunderstorm development is expected over much of eastern Nebraska and Southwest Iowa. These storms could persist into the overnight hours. Any storms that do develop are capable of producing large hail and damaging winds, mainly during the late afternoon and evening hours. Later in the evening and overnight, the storms may produce locally heavy rain.

Spotter activation may be needed after 3-p.m. across the affected counties.
