- A powerful line of severe thunderstorms known as a "Derecho" tracked across eastern Iowa and northwest Illinois on the afternoon of Monday, August 10th producing widespread straight line wind damage. A swath of damage from Benton County, through portions of Linn, Jones, Cedar, and Clinton Counties, is consistent with intermittent straight line winds in the 100-130 mph range. Maximum estimated winds were around 140 mph, which caused extensive damage to an apartment complex in southwest Cedar Rapids, IA. Straight line winds of this magnitude are equivalent to an EF3 tornado. The maximum measured unofficial wind gust was 126 mph at Atkins, Iowa in Benton County.
A derecho of this intensity is a roughly once-in-a-decade occurrence in this region. Other notable derechos occurred in 1998 and 2011. What is unique about this event, making it even more extreme, is the long duration of the high winds. Many locations experienced sustained high winds and damaging gusts for 30 to 45 minuties. One storm-related fatality has been reported so far in the NWS Quad Cities area of responsibility. The Linn County Sheriff's Department reports a bicyclist died after being struck by a falling tree. There were numerous injuries reported, especially in the Cedar Rapids area.
Storms initially developed in northern Nebraska and southeast South Dakota early in the morning, and quickly intensified as they moved eastward into Iowa. Storms quickly became severe in western Iowa, and produced damaging winds near and around the Des Moines metro. At this point, storms began to tap into an extremely unstable environment, and began producing more widespread wind damage as they tracked through eastern Iowa. The most extreme winds, estimated at 110-140 mph, destroyed or damaged numerous outbuildings, barns, grain bins, homes, mobile homes, apartment buildings, trees, and power poles in parts of Benton, Linn, Jones, Cedar, and Clinton Counties. The Cedar Rapids area was particularly hard hit. Several homes, apartment complexes, and businesses sustained damage consistent with 130-140 mph winds. Radio transmission towers in Marion and Clinton, IA collapsed due to winds estimated around 130 mph. Winds gusts of 80-100 mph were common as the line of storms moved through the Quad Cities area and then through northwest Illinois. A small pocket of winds estimated at 100-110 mph impacted Princeton, IL in Bureau County, where a 150 foot communications tower collapsed and numerous power poles were snapped. In addition to the damage, numerous long-duration power outages occurred across the region. Numerous semi trucks were also blown off of major highways.
I remember my brother called me and told me he was going to come to my place to take shelter about 5 minutes after the storm started. It was actually pretty awesome to see everything flying around outside. I was in my hallway waiting for him with my portable weather radio listening to reports about the storm.
I saw this storm at my folks house in Indiana. It was AWESOME! I love storms. Slot!!
I remember being at my apartment when it hit in Iowa City, but after it passed I had power still. My cell phone company’s signal wasn’t working good that much and didn’t had any internet until it went back up on that Thursday.
I was working at Goodwill Cedar Rapids Center when I saw the skies getting darker and then when the lights inside the building started flickering, I went right to the bathroom to take cover. It was the first time since I became a staff member of Goodwill Cedar Rapids Center that after the derecho, work was called off and we lost power for a few days.
Wow!
So that’s what that looked like on radar....
The winds around Cedar Rapids were around a category 1 or 2 hurricane.
40:35 HUGE warning. Nothing like hearing your weather radio go off for three counties over.
Ours didn't till it was almost upon our area
I can only imagine
The warning was for 90 mph winds this confirmed 100 mph + winds. Why do they underplay it and keep saying up to 70 mph? Even after those winds came through cedar rapids they say 70 mph. Ridiculous.
Maybe it was scattered? Mostly everybody had 70mph but some had 100+
@@sllidste the severe thunderstorm warning from the National Weather Service said 90 mph winds.
NWS Quad Cities failed all of us here in eastern Iowa, and the SPC in Norman, OK did too.
@@sllidste we had 80 in the metro, thought that was bad enough, Cedar Rapids on the other hand
Around the hour mark you can see the glass bowing in the wind. 😬
Wow!
WHY IS THE WORST DAY IN THE MONTH STARTS ON MONDAY
That's seriously strong winds to knock over Semi Trucks! Wonder what they clocked the MPH at. 50-60?
Some areas were around 70-80 mph while there were spots over 100 mph with one location clocked at 140 mph.
@@scottschell highest measured was 126 mph in Atkins, with 140 mph estimated (by NWS) due to damage to an apartment complex and nearby building in SW Cedar Rapids.

@@progenitor_amborella Clinton Iowa reported 130mph wind gust
It was 140 mph in my neighborhood. The gym and laundromat I used to go to looked like Godzilla had flattened them. Many other buildings in my neighborhood are gone, to say nothing of the trees.
140mph in NE Cedar Rapids where I live. Looked like a bomb went off

Mine, too
140? Nah, closer to the 90 - 110 mph range
@@TheRealMiamiman70 actually they recorded nearly 100 sustained with gust to 112 in Hiawatha.
Actually that was not anemometer recorded and isnt backed up by any velocity data.
It was some guy's estimate.
What your neoighbor's house probably experienced was poor building codes because you live in iowa, or a tornado.
Max wind hit 100 sustained gust 112 and possibly up to 120.
If possible can you do the Davenport iowa news coverage🙂

Don't most thunderstorms only occur over a short period of time?

@@supercell1995 most of the time yes but just depending on how fast the storm is moving and what type of thunderstorm it is
