| Brief Description: Three supercell thunderstorms dropped large hail and tornadoes across northeast and central Wisconsin during the afternoon and early evening. The first two storms developed quickly over central Wisconsin and then tracked east-southeast through the Fox Cities. These two storms primarily produced large hail (1 to 2 inches in diameter) and some wind damage. A brief tornado touched down with the first storm near Menasha (Winnebago co.). The third storm developed farther north in the northeast part of the state. This storm evolved more slowly, but went through the classic life-cycle of a tornadic supercell and spawned an F3 tornado in Door county. Large hail struck the Fox Cities, especially Appleton, producing over $5 million in damage to vehicles and roofs of buildings. This was the second multi-million dollar hailstorm this year in Appleton. In Sherwood (Calumet co.), hail damage to a golf course was so severe that it did not open until two days later. In Brillion (Calumet co.), hail shattered large glass panels of a church. The most severe damage occurred when a tornado tore a path 5.1 miles long and over a half-mile wide across Door county. The tornado came onshore from Green Bay at Murphy Park, on the Door county west coast at 630 pm. Thousands of trees were flattened in the heavily wooded area. About 30 homes, businesses and barns were destroyed or heavily damaged by the storm, but only two minor injuries were reported. Some livestock, however, including five horses, were lost. The tornado knocked down seven power poles holding electrical transmission lines, bringing blackouts to most of the north half of Door county. Thirty adults and 17 children at a campground found refuge in a concrete building as the tornado approached the grounds. Two minor injuries occurred at the camping resort as it took a direct hit. The twister made it almost two-thirds of the way across the county, before dissipating about 3 miles west of the Door county east coast. | |||||||||||

| Brief Description: EVENT NARRATIVE: The long-track tornado moved from Langlade Co. into Oconto Co. about 8 miles west of Mountain at 4:58 PM CDT. The tornado reached a width of three-quarters of a mile wide as it flattened over 7000 acres of trees in the Chequamegon-Nicolet National Forest (DI 27, DOD4). The tornado destroyed or heavily damaged 12 homes (DI 4, DOD 11), with 14 others sustaining damage of varying degrees. Nearly all of the damaged homes were either manufactured homes or vacation cottages. Two people sustained minor injuries as they sought shelter in a bedroom of their home. The tornado dissipated about 10 miles east-northeast of Lakewood, near the Marinette County line, at 5:18 PM CDT. The tornado was rated EF2 in Langlade Co., with estimated winds of 125 to 135 mph, and an average path length of 1000 yards. EPISODE NARRATIVE: An unseasonably strong upper level storm system and deep surface low pressure (with central pressure as low as 979 mb) interacted with a cold front that moved from west to east across the area during the late afternoon and evening. A moist and unstable airmass ahead of the cold front provided the fuel to generate severe thunderstorms that included five tornadoes, near record-size hail and damaging winds. Thousands of homes sustained damage and about 15,000 customers lost power during the storms, some for almost 3 days as trees blocked roads and slowed repair work to power lines. Four people sustained minor injuries, and total damage from the storms exceeded $60 million. The first tornado of the outbreak moved across eastern Marathon County shortly after 4:00 PM CDT, producing damage to several homes. The tornado was rated EF2. A second thunderstorm produced a weak tornado in Wood County, which was rated EF0. The same storm responsible for this tornado produced softball size hail that damaged thousands of homes, several businesses and hundreds of vehicles. One hailstone that fell in Port Edwards measured 5.50 inches in diameter, making it the second largest hailstone on record in Wisconsin. The same supercell thunderstorm that produced the Marathon County tornado also produced a long-track tornado across northeast Shawano, northwest Menominee, southeast Langlade and northern Oconto counties. This tornado was on the ground for 47 minutes, covering 40.1 miles, and destroyed 14,400 acres of woodlands (timber loss was estimated at $12.5 million) and dozens of buildings along its path. The twister, which was over one-half mile at times, was rated EF3, with peak winds estimated of 150 to 160 mph. The storm responsible for the tornado also produced significant straight-line wind damage as it moved into western Marinette County. The fourth tornado of the outbreak, rated EF1, developed near Cedarville in Marinette Co., which was from the same thunderstorm that produced the long-track tornado. The final tornado of the afternoon and evening touched down near Harmony in Marinette Co. This tornado was rated EF1. Details of the tornadoes, hail, and wind damage can be found in the event narratives of the affected counties. | |||||||||||

| Brief Description: EVENT NARRATIVE: The long-track tornado moved from Menominee Co. into Langlade Co. about three miles south of White Lake at 4:48 PM CDT. Significant damage occurred as the tornado grew to just over one-half mile. The Bear Paw Outdoor Adventure Resort sustained severe damage with nearly every building (ten) damaged or destroyed, including a three-story inn that was pushed over by the high winds. Only nine people were on site at the time of the tornado; hundreds were expected the next day for the upcoming weekend. One employee at the resort was injured, suffering minor cuts to the head. Hundreds of acres of trees were flattened, and nine homes sustained damage. The average width of the tornado was 700 yards as it moved across the county. The tornado was rated EF3 (DI 6, DOD 9; poorly anchored buildings) with winds estimated of 150 to 160 mph. The tornado exited Langlade Co., around 6 miles east-northeast of White Lake, and moved into Oconto Co. at 4:58 PM CDT.
