As of Monday evening December 29th, NWS Chicago has confirmed 5 tornadoes (1 in Livingston County, 4 in Iroquois County) and a severe microburst (Fairbury-Forrest area in Livingston County). Damage in the Gibson City area of Ford County is still being investigated. .Fairbury - Forrest... The survey team confirmed that a concentrated area of straight- line wind damage in and west of Forrest was produced by a microburst with estimated peak winds of 80 mph. According to radar and reports, the microburst is estimated to have occurred around 10:34 AM CST on 12/28/2025. Damage consisted of downed power poles and trees, at least one shed blown off of its foundation, and a portion of Prairie Central Junior High School's gymnasium getting blown off. .Pontiac... Rating: EF1 Estimated Peak Wind: 90 mph Path Length /statute/: 0.95 miles Path Width /maximum/: 125 yards Fatalities: 0 Injuries: 0 Start Date: 12/28/2025 Start Time: 02:53 PM CST Start Location: 1 NW Pontiac, Livingston County, IL Start Lat/Lon: 40.8879 / -88.656 End Date: 12/28/2025 End Time: 02:54 PM CST End Location: 1 N Pontiac, Livingston County, IL End Lat/Lon: 40.8932 / -88.6392 Survey Summary: This tornado began just south of 4H Park Rd. on the northwest side of Pontiac and immediately moved northeast across the Motorola and Vermilion Estates subdivisions. There, it caused roofing and siding damage to a number of houses, apartments, and manufactured homes. Two houses had large portions of roofing blown off, leaving the attics exposed. The tornado then crossed IL Route 23 and produced additional siding and fascia damage to a few manufactured homes in the Redwood mobile home park before ending north of E 1830 North Rd. The storm also damaged a number of trees in its path. .West of Clifton... Rating: EF0 Estimated Peak Wind: 80 mph Path Length /statute/: 2.64 miles Path Width /maximum/: 100 yards Fatalities: 0 Injuries: 0 Start Date: 12/28/2025 Start Time: 03:31 PM CST Start Location: 6 WNW Ashkum, Iroquois County, IL Start Lat/Lon: 40.9244 / -88.0522 End Date: 12/28/2025 End Time: 03:34 PM CST End Location: 4 W Clifton, Iroquois County, IL End Lat/Lon: 40.9378 / -88.0061 Survey Summary: This tornado formed west of Clifton near the intersection of N 400 East Rd. and E 2900 North Rd. Three power poles were snapped as the tornado tracked across E 2900 North Rd. At a property at the intersection of N 500 East Rd. and E 2900 North Rd., tree damage was noted, and roofing material was peeled off of a house. As the tornado continued to move east-northeastward and crossed N 600 East Rd. and E 2950 North Rd., two farm outbuildings had portions of their roofs ripped off at the same property. Additional tree damage was also noted. The tornado likely lifted before reaching N 700 East Rd. .Gibson City 1.5 S... A portion of the roof of the one of the Dairyland Seed buildings was destroyed at approximately 3:32 PM CST on 12/28/2025. NWS Chicago meteorologists, in coordination with Gibson City officials and the Ford County EMA, will complete their investigation of this damage and confirm its cause within the next day or two. .Clifton - St. Anne... Rating: EF1 Estimated Peak Wind: 95 mph Path Length /statute/: 9.53 miles Path Width /maximum/: 150 yards Fatalities: 0 Injuries: 0 Start Date: 12/28/2025 Start Time: 03:40 PM CST Start Location: 1 ENE Clifton, Iroquois County, IL Start Lat/Lon: 40.9388 / -87.9033 End Date: 12/28/2025 End Time: 03:51 PM CST End Location: 2 SW St. Anne, Iroquois County, IL End Lat/Lon: 41.0028 / -87.7453 Survey Summary: This tornado likely began in a field approximately two miles east of Clifton based on a tight gate-to-gate velocity couplet sampled by the KLOT radar. In the first few minutes of its lifespan, the tornado largely remained over open fields and may have briefly lifted as little damage was observed near and west of U.S. Highway 45/52. However, the tornado strengthened as it tracked across and east of N 1500 East Rd. At the intersection of E 3100 North Rd. and N 1600 East Rd., a residence had a sizable portion of its eastward- facing roof torn off and deposited in the downstream field. Several trees at this property were damaged as well, including one softwood tree whose top was snapped off and tossed about 100 yards to the east. At the adjacent property to the east-northeast, a barn was shifted off of its foundation and had a portion of its roof peeled. As the tornado reached the Iroquois River, it tore the roof off of a garage and peeled roofing material off of a house at a property next to the river. Extensive tree damage was noted at this property and just to the east along the river, where multiple trees were uprooted and dozens of trees lost limbs and branches. It here where the tornado was estimated to have reached its peak intensity. The tornado weakened east of the Iroquois River, but continued to cause tree damage as it approached and crossed N 1800 East Rd. A residence along N 1900 East Rd. and two additional barns along N 2000 East Rd were then damaged by the tornado. The tornado lifted over a field southwest of St. Anne, shortly after it tipped over an irrigation pivot. .Northeast of Clifton... Rating: EF0 Estimated Peak Wind: 85 mph Path Length /statute/: 3.35 miles Path Width /maximum/: 75 yards Fatalities: 0 Injuries: 0 Start Date: 12/28/2025 Start Time: 03:41 PM CST Start Location: 2 SE Chebanse, Iroquois County, IL Start Lat/Lon: 40.9693 / -87.8889 End Date: 12/28/2025 End Time: 03:46 PM CST End Location: 4 ESE Chebanse, Iroquois County, IL End Lat/Lon: 40.9821 / -87.8272 Survey Summary: This tornado likely began near or just west of N 1300 East Rd. northeast of Clifton, where some twigs and branches were downed across the road. Little to no damage was observed as the tornado tracked across fields on either side of U.S. Highway 45/52. The tornado then impacted a farmstead along N 1500 East Rd. just north of E 3200 North Rd., peeling roof shingles off of the house at the property and damaging multiple farm outbuildings. One outbuilding was blown off of its foundation, while another collapsed entirely after it was penetrated by the tornado's estimated 85 mph peak winds. The tornado likely lifted before reaching the Iroquois River as no damage was noted to the treeline along the river or anywhere east of there. .Martinton... Rating: EFU (unknown intensity) Estimated Peak Wind: N/A Path Length /statute/: N/A Path Width /maximum/: N/A Fatalities: 0 Injuries: 0 Start Date: 12/28/2025 Start Time: 03:55 PM CST Start Location: Approx. 1 SW Martinton, Iroquois County, IL Start Lat/Lon: TBD End Date: 12/28/2025 End Time: 03:59 PM CST End Location: Approx. 0.75 SE Martinton, Iroquois County, IL End Lat/Lon: TBD Summary: Based on storm spotter and storm chaser reports, videos, and photos of a funnel cloud extending nearly to the ground, a brief tornado was confirmed to have occurred. This tornado appeared to have tracked across open farm fields just south of Martinton and thus produced no known damage. A video of the tornado lifting behind the Martinton water tower at about 3:59 PM had a view towards the southeast from N 2100 East Rd near the intersection with County Rd 2800 N. Thus, the tornado ended approximately in the vicinity of County Rd 2750 N. && EF Scale: The Enhanced Fujita Scale classifies tornadoes into the following categories: EF0.....65 to 85 mph EF1.....86 to 110 mph EF2.....111 to 135 mph EF3.....136 to 165 mph EF4.....166 to 200 mph EF5.....>200 mph NOTE: The information in this statement is preliminary and subject to change pending final review of the events and publication in NWS Storm Data. $$ NWS Chicago

Rating: EF0 Estimated Peak Wind: 85 mph Path Length /statute/: 0.85 miles Path Width /maximum/: 20 yards Fatalities: 0 Injuries: 0 Start Date: 12/28/2025 Start Time: 03:32 PM CST Start Location: 2 S Gibson City / Ford County / IL Start Lat/Lon: 40.4405 / -88.3809 End Date: 12/28/2025 End Time: 03:33 PM CST End Location: 1 SSE Gibson City / Ford County / IL End Lat/Lon: 40.4456 / -88.3662 Survey Summary: A large, west-facing section of the metal roof of the southernmost building at the GDM (formerly Dairyland Seed) facility south of Gibson City was peeled eastward as a developing miniature supercell storm passed overhead. While no condensation funnel was evident, eyewitnesses reported visible rotation in the clouds passing over the facility and debris from the impacted building getting lofted and swirled around in the air before getting deposited in the field to the east of the facility. This would suggest that a brief tornado occurred here. This tornado appeared to only cause high-end EF-0 damage to the one building at the GDM facility before ending a few hundred yards to the east-northeast. .Clifton - St. Anne...
