This article recaps a day of severe weather across the Quad Cities region on March 10. It details tornado warnings, radar indicators, large hail, heavy rain, power outages, public response, and ongoing monitoring by meteorologists.
Local authorities issued multiple alerts as the system tracked eastward. Residents were urged to shelter when warned and to report storm damage.
What happened as the storm moved through the Quad Cities region
Weather teams tracked a shifting threat through the evening hours. Activity wound down by late night, but lingering rain and non-severe storms persisted overnight. Northern towns faced a risk of wet snow as precipitation rolled in behind the main storm system.
A Tornado Warning was issued at 9:45 p.m. for southeastern Bureau County after Doppler detected rotation. No confirmed tornado was reported in that specific area.
Earlier in the evening, radar-indicated rotation suggested tornadic potential as the storm moved toward eastern Iowa and western Illinois.
Radar signals, warnings, and confirmed touchdowns
- 6:30 p.m. — A Tornado Warning was issued for parts of Henry and Bureau counties, with radar indicating rotation and hail up to golf-ball size near Kewanee.
- 9:10 p.m. — A confirmed tornado was reported in Donnellson, south of Burlington, moving east toward Fort Madison. Residents in its path were advised to shelter.
- 9:45 p.m. — Tornado Warning for southeastern Bureau County and surrounding areas as radar continued to show rotation. No confirmed tornado was reported in that location at that time, while the storm tracked toward Des Moines County, IA, and Henderson and Warren counties in IL.
- As the night advanced, a broader pattern of heavy rain, strong winds, and large hail continued across the region. Severe storm cells capable of producing dangerous weather lasted into the early hours.
The National Weather Service and KWQC had previously issued a Tornado Watch followed by a First Alert Day for much of eastern Iowa and western Illinois. They highlighted a level 1–4 out of 5 risk and particular concern for strong, potentially long-track tornadoes and very large hail exceeding 2 inches in diameter.
These alerts underscored the potential for rapid changes in storm intensity and the need for timely shelter decisions.
Impacts on communities: hail, rainfall, and infrastructure
The evening produced a broad range of severe-weather impacts that affected hundreds of residents. Heavy rainfall led to flash-flood concerns in several areas.
Warnings remained in effect for portions of Henry and Bureau counties due to repeatedly intense downpours and rising water levels. The storms generated significant lightning, gusty winds, and unusually large hail.
Reports included pea-sized to baseball-sized hail, including baseball-sized hail in southern Louisa County.
- Power outages: Hundreds of customers across affected counties experienced outages as the storms unfolded.
- Flooding risk: Flash Flood Warnings persisted where rainfall rates remained high, especially in lower-lying areas.
- Abrupt weather changes: By around 10:00 p.m., the overall severe threat was winding down. Lingering showers and non-severe storms were expected to persist overnight, with a possibility of wet snow in northern towns.
The broadcast and weather teams encouraged residents to share photos and videos of storm damage as conditions evolved. This aided local response efforts and helped verify storm reports in near real time.
The First Alert Weather team maintained close monitoring, delivering updates as the system progressed toward the Mississippi River corridor.
Public safety messages and monitoring going forward
In the wake of the outbreak of severe weather, officials emphasized the importance of heeding warnings, especially during Tornado Warnings and Flash Flood Warnings.
Viewers were reminded to seek shelter immediately when told to do so. They were also advised to stay informed via trusted local sources as the weather pattern shifted eastward.
The combination of heavy rain, hail, and potential power disruptions underscored the ongoing need for vigilance through the overnight hours.
Takeaway for residents: monitor official weather updates and have a plan for shelter in your area.
Be prepared for rapid changes in storm intensity during spring weather events.
