Severe Thunderstorms Pound St. Louis Metro Area With Ping Pong Ball-Size Hail
Multiple severe thunderstorm warnings issued as dangerous storms with ping pong ball-size hail and 60 mph winds swept across the St. Louis metro area Saturday night.
ST. CHARLES, MISSOURI — A series of severe thunderstorms moved through the St. Louis metropolitan area late Saturday night, bringing ping pong ball-size hail and wind gusts up to 60 mph as the weather system traveled east across multiple counties.
The National Weather Service in St. Louis issued several severe thunderstorm warnings throughout the evening, beginning at 9:56 PM CDT and extending until 11:45 PM CDT as radar tracked the fast-moving storms across the region.
Storm Path and Timeline
The severe weather began northwest of Hawk Point at 9:56 PM, located 14 miles north of Warrenton and moving east at 45 mph. By 10:27 PM, the storm had intensified near Winfield, 7 miles north of St. Paul, accelerating to 50 mph as it approached the St. Charles area.
The most dangerous phase occurred at 10:38 PM when meteorologists tracked a severe thunderstorm 6 miles west of Grafton, or 11 miles north of St. Charles, moving east at 50 mph. This storm maintained its intensity through 11:45 PM, threatening multiple communities along its path.
Areas Under Warning
The severe thunderstorm warnings covered southeastern Jersey County in southwestern Illinois, southern Macoupin County in southwestern Illinois, northwestern Madison County in southwestern Illinois, and northeastern Saint Charles County in east central Missouri.
Communities directly in the storm’s path included Grafton, Orchard Farms, Portage Des Sioux, Elsah, Godfrey, West Alton, Winfield, St. Paul, O’Fallon, Chain of Rocks, St. Charles, and St. Peters. The National Weather Service also warned that the storms would impact Fosterburg, Hamel, Fruit, Brussels, Deer Plain, Golden Eagle, Meppen, Beechville, Batchtown, Old Monroe, Kampville, Truxton, Cave, and Silex.
Damage Potential and Safety Concerns
Weather officials warned that people and animals outdoors could be injured by the severe conditions. The combination of ping pong ball-size hail and 60 mph wind gusts posed significant risks to property and safety.
According to the National Weather Service, residents could expect hail damage to roofs, siding, windows, and vehicles throughout the affected areas. Wind damage to roofs, siding, and trees was also anticipated as the storms maintained their intensity across the region.
Pere Marquette State Park was among the recreational areas specifically mentioned in the warnings, as officials tracked the storms’ impact on outdoor locations where people might seek shelter.
The radar-indicated storms represented a typical spring severe weather pattern for the St. Louis region, though the sustained intensity and large hail size made Saturday night’s system particularly noteworthy for local meteorologists and emergency management officials.
