After receiving several tornado and wind damage reports in Winnebago and Jasper Counties from Sunday evening’s storm, the National Weather Service did a survey on the damage. The survey team confirmed that there were three tornadoes around the area and straight-line wind damage in Rockford where one person was injured. Tornadoes were confirmed in Rensselaer, IN, Polo and Adeline, IL.
At around 4:37pm, a tornado touched down one mile north of Rensselaer, IN near Wood Road and West Amsler Road. The tornado crossed US Hwy 231 and caused EF-1 damage to the roof of the Farm Bureau Insurance building at 2570 North McKinley Avenue as well as soffit, fascia and window damage to the Purdue Agricultural Extension office just to the west. Winds from the EF-1 tornado ranged between 86 and 110 mph. The path length was 100 yards and the width was 20-33 yards.
One mile southeast of Polo, IL, a tornado touched down just south of the intersection of Union Road and Judson Road. The tornado began as a low-end EF-1 with winds between 85 and 90 mph when a power pole was seen leaning over the road. As the tornado tracked eastward, it gained strength uprooting a tree, and damaging roofs to four buildings and a wood outbuilding. The tornado reached its max intensity with winds near 100 mph where it snapped several trees and a power pole in half, blew over a roof, and ripped a grain bin off its foundation. The EF-1 tornado had a path length of 1 1/2 mile and a width of 200 yards.
A long-tracked tornado (17 miles long) was observed in Adeline, IL, roughly one south of Winnebago County. Around 6_30pm, a tornado touched down just east of Forreston, on Columbine Road near Illinois Route 72, at 7833 Columbine Road in Ogle County. The tornado continued to the northeast with a near continuous path into Winnebago County, lifting near Kelly Road east of just Alworth Road. Persistent EF-1 damage was observed during much of the tornado’s path. Several trees were damaged/uprooted. Structural damage included several collapsed outbuildings, damaged siding and fascia to homes, and shingles blown off roofs. A mobile home lost part of its roof with walls partially collapsed in Adeline. Another double wide home lost a portion of hits roof on Leaf River Road at Myrtle road. A couple of utility poles were also snapped or leaning over. All of the damage suggested winds from 90-110 mph. Winds ranged from 90 to 110 mph.
Straight-line wind damage with winds between 90 and 110 mph was confrmed in west Rockford and Roscoe, IL near Winnebago County. There was sporadic wind damage around the area, but damage was more concentrated around the Roscoe Fire Station, where a large garage door was blown in, and around the Kennedy middle school which had part of a roof blown off.
