| Brief Description: EVENT NARRATIVE: The long-track tornado moved into Menominee Co. from Shawano Co. about 7.8 miles west-northwest of Neopit at 4:32 PM CDT. Three thousand acres of trees were snapped or uprooted, many in prime stands of maples, some 150 to 200 years old. The tornado exited Menominee Co. and moved into Langlade Co. at 4:48 PM CDT. The average path width of the tornado in Menominee Co. was 500 yards wide, and damage was rated EF2 (DI 27, DOD 4) in this segment, with estimated winds of 120 to 130 mph. 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.

| Brief Description: Severe thunderstorms affected much of northern, central and east-central Wisconsin during the afternoon and evening of July 16 with tornadoes, downburst winds and large hail. Millions of dollars in damage resulted from the biggest severe weather outbreak to affect the region in years. The storms began to develop early in the afternoon across north-central Wisconsin. Hail the size of baseballs fell in Minocqua (Oneida co.), damaging nearly 200 vehicles. As those storms moved southeast and weakened, a new supercell thunderstorm developed over Lincoln county. This new storm produced wind damage in Tomahawk and softball size hail northeast of Merrill. About 20 minutes later, a tornado developed in southeast Lincoln county and moved southeastward into Marathon county. This tornado, rated F2, was on the ground for more than three miles. It damaged several homes, vehicles and silos, and destroyed numerous barns, sheds and crops. Twenty head of dairy cattle were killed or had to be destroyed. As the tornadic supercell moved southeast, it produced two other weak tornadoes. Total damage to crops and property from five tornadoes, hail and straight-line winds in Marathon county alone topped $10 million. Another supercell thunderstorm produced a downburst swath of damage over three miles wide and 14 miles long from southeast Langlade county, through western Menominee county, into extreme north-central Shawano county. Menominee county was especially hard hit, as tens of thousands of trees were felled in the heavily forested county. Authorities estimated that nearly 25 million board feet of lumber was on the ground; it was hoped that much of it was going to be salvaged. At the height of the storm, winds were estimated to be near 100 mph. As the storm weakened and moved into north-central Shawano county, a 70 mph wind gust was measured near Morgan. Another storm in western Shawano county produced a downburst which downed trees across the city of Wittenberg. Part of a roof was blown off an apartment building in the downtown area, and several houses and businesses sustained damage from the fallen trees. A Wittenberg man was injured by flying glass. Lightning set a house on fire, destroying the second story, in the township of Germania. Another storm struck Waupaca county, producing high winds. A power pole fell and hit a car in New London, injuring the driver. Shortly after 530 pm, a supercell thunderstorm produced numerous wind gusts over 65 mph across the Fox Valley, blowing over many trees, damaging buildings and causing a fatality. A 36 year-old male was killed when a tree fell on his minivan in Oshkosh (Winnebago co.). His young daughter was uninjured in the accident. A wind gust to 82 mph was measured in Appleton (Outagamie co.), and a gust to 67 mph was recorded in Oshkosh. Thunderstorms over Waushara county produced flooding rains, a brief tornado, strong winds and hail. Over five inches of rain fell in only three hours near Hancock, producing some basement and street flooding. A brief tornado also touched down in an open field in Hancock. Numerous trees and powerlines were blown down in Wautoma. A thunderstorm knocked trees and power lines down in Kiel (Calumet/Manitowoc co.), and damaged seven tents at a fair in Cleveland (Manitowoc co.). | |||||||||||

| Brief Description: Thunderstorms that developed ahead of a strong cold front that moved through Wisconsin produced severe weather in the central and east central parts of the state during the evening. A line of thunderstorms tore the roof from a barn, downed numerous trees and power lines and blew a pickup truck into a ditch as the storms moved through the Wood county communities of Vesper, Nekoosa, and Wisconsin Rapids. Glass fragments caused a minor injury to one of the occupants of the pickup truck. The storms also produced 7 minutes of dime size hail 1 mile east of Wisconsin Rapids. The storms also damaged several buildings 4 miles west of Stevens Point (Portage co.), downed trees in Saxeville (Waushara co.) and dropped quarter size hail in Plover (Portage co.). As the storms moved through Portage county three tornadoes touched down. One of the tornadoes caused minor tree damage in an industrial park in Whiting. Eyewitnesses observed water being sucked out of a pond at the same time as doors to an office were sucked open. Another tornado downed several trees, knocked down a fence, damaged the roof of a house and damaged some outbuildings as it passed north of Almond. The third tornado was the strongest and was on the ground intermittently for 10 miles from southeast Portage county into southwest Waupaca county. It downed trees and overturned an irrigation system in Portage county. It strengthened in Waupaca county where it scoured asphalt off a road, destroyed a barn, sheared off the top 50 feet of a silo, crushing three calves, damaged a sheet metal outbuilding and killed 3 sheep. It tore the roof from a house and destroyed the garage, overturned a semi trailer and moved it 50 feet, blew hay wagons against trees and snapped off or uprooted numerous trees. Some of the debris from this tornado landed several miles east in the Fremont area (Waupaca co.). A tornado touched down in at least four locations from Little Chute to Kaukauna as the storms moved across Outagamie county. It toppled or twisted large trees, ripped parts of the roofs from residential and commercial buildings, destroyed storage sheds and an old barn and overturned semi trailers and dropped some of them on other vehicles. A brief tornado touchdown also occurred on the west side of Green Bay (Brown co.) where it caused some tree damage. | |||||||||||

| 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. | |||||||||||

Menominee county was especially hard hit, as tens of thousands of trees were felled in the heavily forested county. Authorities estimated that nearly 25 million board feet of lumber was on the ground; it was hoped that much of it was going to be salvaged. At the height of the storm, winds were estimated to be near 100 mph. As the storm weakened and moved into north-central Shawano county, a 70 mph wind gust was measured near Morgan. Another storm in western Shawano county produced a downburst which downed trees across the city of Wittenberg. Part of a roof was blown off an apartment building in the downtown area, and several houses and businesses sustained damage from the fallen trees. A Wittenberg man was injured by flying glass. Lightning set a house on fire, destroying the second story, in the township of Germania. Another storm struck Waupaca county, producing high winds. A power pole fell and hit a car in New London, injuring the driver. Shortly after 530 pm, a supercell thunderstorm produced numerous wind gusts over 65 mph across the Fox Valley, blowing over many trees, damaging buildings and causing a fatality. A 36 year-old male was killed when a tree fell on his minivan in Oshkosh (Winnebago co.). His young daughter was uninjured in the accident. A wind gust to 82 mph was measured in Appleton (Outagamie co.), and a gust to 67 mph was recorded in Oshkosh. Thunderstorms over Waushara county produced flooding rains, a brief tornado, strong winds and hail. Over five inches of rain fell in only three hours near Hancock, producing some basement and street flooding. A brief tornado also touched down in an open field in Hancock. Numerous trees and powerlines were blown down in Wautoma. A thunderstorm knocked trees and power lines down in Kiel (Calumet/Manitowoc co.), and damaged seven tents at a fair in Cleveland (Manitowoc co.). | |||||||||||
