Tornado Report Description: This tornado is a continuation of a segment that started in Kenosha County. It quickly intensified to an EF-1 rating after moving into Racine County. It moved into southern Racine County about 2.3 miles southwest of Union Grove, around 1,700 feet to the east of the intersection of County Line Road and 224th Avenue. The tornado moved northeast before dissipating near the intersection of County Highway K and County Highway H, about 1/2 mile southeast of Franksville. There were no fatalities, but 2 people were injured in storm-related vehicle accidents. Newspaper articles indicated they were hospitalized. Union Grove bore the brunt of the damage. Eleven buildings, fencing, and trees were damaged on the Racine County Fairgrounds. Large oak trees in Old Settler's Park, which is the northwest corner of the Racine County Fairgrounds, were hit hard. Across the street (STH 11), two businesses had large pieces of roof covering peeled off. One of these, Grove Gear, had about 10,000 square feet of it's roof ripped off, which allowed rain to damage the inside offices and equipment. Newspaper articles indicated that damage to Grove Gear alone was about $1.4 Million. Two other businesses also had roof and siding damage. A residential-care facility had several of its buildings damaged. Around 100 homes in the Village of Union Grove sustained light to moderate damage to roofs, windows, and/or siding, and numerous trees were either uprooted or had large branches broken or snapped. Numerous gas leaks in and around Union Grove were reported. Only one home was extensively damaged and had to be demolished. A semi-trailer truck overturned on Interstate 94 near State Highway 20, blocking the northbound lanes, as the tornado crossed the interstate. Another semi-trailer was blown over on eastbound Highway 20 near the west frontage road next to the interstate. A number of campers were overturned and one was destroyed at the Burlington RV store at the intersection of STH 20 and Interstate-94. WeEnergy Utility estimated that 3200 customers lost electrical power in Racine County. The path of the tornado averaged 75 yards in width. A detailed examination of the tornado path suggests that this tornado consisted of three or four individual vortices, with one taking over as the previous one dissipated. Each vortex had it own path, which resulted in segmented-appearance of the tornado path as shown in the associated image attached to this severe weather episode. Although the header strip for this tornado event indicates a path length of 10.57 miles, a manual map measurement value of 10.67 miles was obtained. The total loss estimate of $5M was received from Racine County Emergency Management. The EF1 estimated wind speed of 105 mph was based on DI 21(MBS) DOD 3. The exact start location is Lat 42.66995 Lon -88.07447. The exact end location is Lat 42.75586 Lon -87.90231.

Tornado Report Description: Thia weak tornado spun up in north-central Kenosha County, about 3.5 miles northeast of Paris. It exited Kenosha County about 3.7 miles northeast of Paris, or .8 miles east of the intersection of KR and D, and entered Racine County about 2.8 miles east-southeast of Union Grove. It proceeded northeast toward the intersection of Interstate 94 and Highway 11, and eventually dissipated 1.8 miles northwest of Sturtevant. Luckily, the tornado circulation wasn't at ground level the entire time, and traveled part of the time over some swamp land, otherwise there would have been more damage. In Racine County, the tornado intensified to the top of the F1 rating (winds about 87 to 96 knots, or 100 to 110 mph), and demolished a hay shed, damaged a pole barn (horse trailer inside was pushed through a closed door), flattened some fence, uprooted or snapped many trees, damaged a road sign, damaged a Sheriff Department speed trailer at the I-94/Hwy 11 intersection, and flattened some corn crop. A couple of power line poles were also damaged. Eyewitness reports indicated that the tornado briefly consisted of multiple vortices, and sounded like a jet engine. Average path length was about 25 yards. Synoptically, a 500 mb circulation center moved northeast through southeast Wisconsin at the time of the tornado. Scattered thunderstorms associated with the low moved northeast at about 30 mph. Maximum air temperatures during the afternoon were in the lower 80s with surface dewpoints in the mid to upper 60s.
