The Easter Week 2006 Tornado Outbreak Sequence was a tornado outbreak sequence during the days leading up to Easter and continued into the first week after Easter. It was the third major outbreak of April 2006, which had been an unusually busy month for tornado activity.
On April 13, a complex of severe thunderstorms formed in eastern Iowa, bringing many reports of large hail along with unexpected reports of strong tornadoes, some with debris. The worst impacts were felt in and around Iowa City where significant damage and numerous injuries were reported, in addition to at least one death across the region.
Another supercell developed on April 14 across western Indiana, touching down a few tornadoes, although nothing very serious was reported. That system moved eastward over the Mid-Atlantic States on April 15, although no tornadoes were reported there.
While the first system moved eastward, a second system developed over the Upper Midwest and tracked across the Midwest on April 15 and 16. This new system has led to about 40 reported tornadoes, and several have been damaging, although no fatalities were reported from the second system.
That system then tracked into the Mid-Atlantic on April 17, and was mostly a straight-line wind event, although there were a handful of new tornadoes reported across the region.
A third system developed on April 18 and brought even more severe weather, this time farther south in the lower Midwest, mainly Missouri. There were several more tornadoes reported from this one.
The severe weather finally came to an end on April 19 across the South, although some tornadoes occurred isolated if any.
Interestingly, the back side of this system produced heavy snow and blizzard conditions over the High Plains.

[edit] Iowa City tornadoes
Several tornadoes touched down in Iowa City in the evening of April 13 between 7:30 and 9:30 p.m. CDT (0030-0230 UTC). The tornadoes affected several parts of town and were likely multiple tornadoes. At least 30 people were injured in the city, but no one was killed in Iowa City (one death was reported southeast of the city in a rural area).
Downtown was hit the hardest, with several buildings suffering heavy damage, and the courthouse and Saint Patrick's Church - one of the local Roman Catholic parishes - both lost their roofs after the tornado hit. Several people were reportedly trapped in collapsed buildings but were rescued. The church had just finished Holy Thursday services but the parishioners were all safely in the basement of the rectory at the time. Good Friday and subsequent services continued as scheduled in the undamaged areas.
It was a Thursday night, which is normally a busy time for the bars of downtown Iowa City. Fortunately the tornadoes struck relatively early in the evening, and downtown was not as packed as it might have been had the tornado struck a few hours later. There were a few reports of looting, mainly at establishments where liquor was sold/stored. After it was certain the storms had passed (and in some cases, before) a few University of Iowa students threw impromptu "Tornado Keggers" from venues undamaged by the storm.
The Iowa National Guard was mobilized and local law enforcement was maximized to prevent crime such as looting in the area. Gas leaks were also reported in the downtown area.[1] The University of Iowa was also hard hit by the tornadoes - the Alpha Chi Omega sorority house was nearly destroyed and had to be evacuated, and several other buildings suffered lesser damage. The school was closed the next day as a result.[2]
Another hard hit area was the south side of town, particularly along Riverside Drive (US 6) south of downtown. The commercial area was heavily damaged, with damage reported to several shopping centers and plazas, several big box stores and numerous fast food restaurants - at least one of which, a historic 54-year old Dairy Queen restaurant [3], was destroyed. Many cars parked in the parking lots also sustained damage. In a parking lot downtown, cars were overturned or crushed from where they had been parked.
Electricity was cut to about 7,000 customers in the area, but most power was quickly restored after the tornadoes, high winds and hail.[4]
The National Weather Service stated that five, possibly six tornadoes were present in Iowa City that night. The first confirmed tornado was a high-end F2, which was the tornado that swept through the downtown area. This was the first tornado on record to strike the University. The second tornado was given a preliminary F0 rating.
Several interesting things happened as a result of the tornadoes:
- UI President David Skorton cancelled classes[5] on Friday, April 14.
- Also on Friday, area governments declared a joint state of emergency for Johnson County[6]
- The Daily Iowan (the University newspaper) continued coverage through the weekend, days on which the newspaper does not traditionally print.
