EF2 tornado in Jasper County, Illinois

As the tornado moved across the Effingham-Jasper county line at the intersection of N 2400th St and E 1400th Ave, it continued on a southeastward trajectory while weakening to EF-2 intensity. With estimated wind speeds of approximately 120 mph,

the storm caused moderate damage to outbuildings and trees, along with minor structural impacts to single-family residences. The tornado continued to the southeast where it caused major roof damage to a two-story house, rolled an SUV, damaged an outbuilding, and snapped several large hardwood trees. Moving southeast toward

E 1700th Ave, the storm snapped the top of another large hardwood

and stripped shingles from a single-story residence, with further

tree damage reported just north of that location. East of N 700th

St, more tree damage occurred alongside shingle damage to a mobile

home. As the tornado tracked further along E 1700th Ave, it damaged

another outbuilding, two grain bins and additional trees before

finally lifting approximately 0.25 miles east of N 800th St.

Several rounds of significant convection impacted central Illinois on June 17th, 2026. Clusters of thunderstorms initially formed on the nose of a strong low-level jet streak across Iowa during the pre-dawn hours, then tracked southeastward along a warm frontal boundary into central Illinois through midday. Scattered damaging wind gusts were reported in north-central Illinois, with the most concentrated corridor of 60-70 mph winds focused along a Galesburg, to Peoria, to Chenoa line.

Thunderstorms re-developed along a remnant outflow boundary from the morning convection by mid to late afternoon, with the most intense cells materializing along and south of a Springfield to Paris line where several tornadoes occurred and hail larger than baseballs (3 diameter) was reported across portions of Moultrie, Douglas, and Coles counties. An EF2 tornado impacted the Mattoon to Charleston area, and an EF3 tracked just north of Effingham.
