Severe Storms Leave Trail of Hail Across Siouxland
SIOUX CITY, Iowa (Archyde.com) — A series of severe thunderstorms swept across Siouxland Thursday and into the early hours of Friday, leaving behind a scattering of damage reports ranging from large hail to wind-related impacts, according to the National Weather Service. While the worst of the storm skirted the immediate Sioux City metropolitan area, several communities experienced significant hail, prompting severe thunderstorm warnings and watches.
The initial storms developed along the Iowa-Minnesota border Thursday afternoon. The first reports of severe weather began trickling in from Dickinson County, Iowa, specifically east and east-southeast of Lake Park, where penny-sized hail, measuring 0.75 inches in diameter, was reported at 3:39 p.m. CDT. Just minutes later, at 3:51 p.m. CDT, nickel-sized hail (0.88 inches) was observed in the same vicinity, approximately two miles east-southeast of Lake Park.
As the initial storm system moved north-northeast, the National Weather Service issued Severe Thunderstorm Watches for much of Northwest Iowa, anticipating the potential for more widespread severe weather later in the day. By 4:45 p.m. CDT, Tornado Watches were also issued for areas further south in Siouxland, although the immediate threat of tornadoes did not materialize at that time.
During the 5 p.m. hour,showers and thunderstorms began to develop across Siouxland,but these storms were generally less intense and concentrated south of Sioux City,closer to the Omaha,Nebraska,area.
The first Severe Thunderstorm Warning for the siouxland region was issued just before 6:30 p.m. CDT for southwestern Harrison County,Iowa,including the town of Missouri Valley. the warning cited the potential for hail up to two inches in diameter and wind gusts reaching 70 mph. While this particular storm’s most intense activity, including large hail and a confirmed tornado, remained south of Harrison County, scattered, less-severe storms began developing throughout the region.
The evening brought additional reports of hail as storms continued to track across the area. At 7:41 p.m. CDT, penny-sized hail (0.75 inches) was reported three miles northwest of Wakefield,Nebraska,marking the start of a new round of severe weather reports.
As the storm cell moved east-northeast, larger hail was reported in other areas:
1 N Homer, NE (8:06 PM CDT): 1.5-inch hail (ping pong ball sized)
1 NE Homer, NE (8:08 PM CDT): 1-inch hail (quarter sized)
* Sergeant Bluff, IA (8:12 PM CDT): 0.88-inch hail (nickel sized)
Radar imagery at the time showed a concentrated area of high reflectivity indicative of the hail-producing storm as it moved through the region.
Later in the evening, a severe Thunderstorm Warning was issued for Woodbury County, Iowa, and western Ida County, citing the potential for 1.5-inch hail. Pea- to nickel-sized hail (0.88 inches) was reported near Bronson, Iowa, at 8:27 p.m. CDT,approximately five miles east of the town.
As of Friday morning, assessment teams are surveying affected areas to determine the full extent of the storm damage. Residents are encouraged to report any damage to local authorities and to exercise caution when traveling in areas that experienced severe weather.
The National Weather Service continues to monitor the weather patterns and encourages residents to stay informed of any potential future severe weather threats.Archyde.com will continue to provide updates as more facts becomes available.

Siouxland Storm Recap: An Interview with Meteorologist Amelia Hayes on the Hail’s Impact
Archyde.com – Following the recent severe thunderstorms that battered siouxland, leaving a trail of hail in their wake, we spoke with Amelia Hayes, a seasoned meteorologist with StormWatch Insights, to unpack the details of the storm and its impact.
Understanding the Storm’s Intensity
Archyde.com: Amelia, thank you for joining us. Can you give us a general overview of what made Thursday’s storms so impactful across siouxland?
Amelia Hayes: Certainly. The primary threat came from the hail, wich, as we saw, reached important sizes in several locations. The Iowa-Minnesota border area saw the initial development, with reports quickly escalating from penny-sized to nickel-sized hail in Dickinson County. This was a solid signal of an unstable atmosphere,ripe for producing severe weather.
Archyde.com: Indeed.Your team issued subsequent warnings for the region.Can you walk our audience through some of the more significant hail reports?
Amelia Hayes: Absolutely. Several communities were particularly affected. We had ping-pong ball-sized hail in homer, Nebraska, and quarter-sized hail in the neighboring area. Sergeant Bluff, Iowa, also experienced nickel-sized hail, indicating widespread severity. These reports, along with the radar data showing high reflectivity, confirmed the intensity of the storm.
Analyzing the Hail’s Patterns
Archyde.com: We saw a distinct geographical spread to the hail reports. Is there a pattern to where these storms seemed to strike most aggressively?
Amelia Hayes: While these storms are inherently unpredictable, the data suggests a corridor of intense activity. The initial storms traveled northeast, and later, the most intense reports continued to move further east-northeast. This indicates the atmospheric dynamics were particularly favorable in that direction.
Archyde.com: The National weather Service also issued tornado watches. What was the overall risk assessment regarding tornadic activity?
Amelia Hayes: Initially, the atmospheric conditions did indicate a risk for tornadic activity. However, the immediate threat of tornadoes didn’t materialize. The focus shifted towards severe hail and wind,which,as events unfolded,turned out to be the primary threats. But the Tornado Watches were necessary given the unstable dynamics at play.
Looking Ahead and Community Action
Archyde.com: The aftermath now involves damage assessment. What’s the main advice to residents at this stage?
Amelia Hayes: The key is to be proactive. Residents should document any damage, report it to local authorities, and exercise caution when traveling. Also, we at StormWatch Insights always reccommend reviewing your insurance to ensure the coverage adequately addresses the impact of hail and other elements.
Archyde.com: what are your thoughts on the role that technology plays in quickly sharing warnings?
Amelia Hayes: Technology is essential, and we rely heavily on it: radar, real-time observation, and sophisticated models, all critical.Early warnings, like those issued by the National Weather Service, are crucial, but the public must also be proactive in accessing and heeding these warnings. The more aware people are, the better prepared they are, and it’s a two-way street.
Archyde.com: Thank you,Amelia. It’s been extremely informative.
Amelia Hayes: My pleasure.
