On July 18, 1996 a violent tornado developed in Fond du Lac County and moved east-southeast toward Oakfield. The village was all but destroyed as the powerful tornado traveled along its 13 mile path of destruction. It became an F5 just east of town before dissipating. Although 12 persons were injured, miraculously no one was killed. [Wisconsin Tornado Database listing #1140].

INTRODUCTION The tornado is one of nature’s most feared and destructive weather phenomenon in the United States. Tornadoes strike the central U.S. more often than any place else on earth due to the right combinations of topography, temperature, moisture, and wind patterns. Every year they devastate the American landscape, taking hundreds of lives, and causing millions of dollars in property and agricultural damages.

A core area comprising the highest frequency of tornadoes in the U.S. extends from northern Texas and Oklahoma, through Kansas and Nebraska (see figure 1). This is the area popularly known as “Tornado Alley,” where northern Texas and Oklahoma experience the highest numbers of tornadoes per square mile. High tornado occurrences also extend north and east of Tornado Alley, extending from extreme southeastern South Dakota, Iowa, central Illinois, and central Indiana. Another area of high activity extends eastward across the Gulf Coast states. Other pockets of major tornado activity can be found across northeastern Colorado and coastal portions of Florida and the Gulf Coast states. Tornadoes occur in all months of the year in the U.S. However, there is a typical season that begins in March, peaking in May through June, and lasts through the summer months (figure 2). The seasonal

distribution corresponds with increasing tornado activity expanding northward during the spring and summer, before waning into autumn. The winter months usually see the fewest tornadoes, which predominantly occur across the southern

tier of states. The higher incidences of tornadoes along the Gulf Coast and eastern coastal Florida may be, in part, explained by frequent tropical storms and hurricanes affecting those areas during the summer and autumn seasons.

WISCONSIN TORNADO OVERVIEW Wisconsin lies at the northern fringe of Tornado Alley and ranks among the top 20 states in the total number of tornadoes. On average, Wisconsin sees about 20 tornadoes and 9 tornado days per year. Tornado occurrences increase rapidly during the spring months, peaking in June, then decline quickly from the late summer through early autumn months. Tornadoes rarely occur during the winter months, and none have ever been reported in the month of February. Tornadoes can strike at anytime of the day, but they most often occur during the late afternoon and evening hours. Tornadoes typically move from southwest to northeast, travel at speeds of 20-40 mph, have path lengths of less than 5 miles, and remain on the ground for less than 10 minutes. Although tornadoes are distributed fairly evenly throughout the state, the highest concentrations are centered over the southeast half. Lesser numbers have occurred across the far north and areas adjacent to the Lake Michigan and Lake Superior shorelines (see figure 3).

Approximately 80 percent of Wisconsin’s tornadoes are rated as “weak,” having wind

speeds of 50 to 100 mph, and about 19 percent are rated as strong, with wind speeds of 110-205 mph. Fortunately, only 1 percent of tornadoes are considered violent with wind speeds exceeding 205 mph. Tornadoes often cause extensive damage and bodily harm. On average, Wisconsin tornadoes kill 2 people and cause 30 injuries annually. The worst single tornado disaster to hit the state occurred at New Richmond, St. Croix County, on June 12, 1899. 117 people were killed and 200 injured as the twister slammed the community on a day on which a well attended circus was in town. Other notable killer tornadoes have struck the state since: In September, 1951, a tornado struck Portage and Waupaca Counties, killing six people; in April, 1956, a tornado struck Berlin (Green Lake County), killing 7 people; in June, 1957, a family of tornadoes struck St. Croix and Dunn Counties, killing 20 people and injuring 110; and on June 7, 1984 a powerful F5 tornado struck Barneveld (Iowa County), killing 9 people and injuring 200 others. Approximately 90 percent of the buildings in that town were either heavily damaged or destroyed. The Wisconsin Tornado Database. During the early years (pre-1950) tornado reports were documented by various sources,

including news items from local newspapers and eyewitness accounts. A few early reports of “tornado damage” may actually have been caused by downbursts or other high wind events generated by thunderstorms. Beginning around 1950 more uniformly distributed tornado information and damage investigations were managed by the U.S. Weather Bureau (and subsequently by the National Weather Service), at a time when modern methods of tornado detection and heightened public tornado awareness had also begun. Since then, tornado accounts have been systematically recorded by the NWS and published monthly in Storm Data, which lists and describes reported tornado events, as well as all types of severe weather occurrences (wind, flooding, hail, etc.), for the U.S. and its possessions. Storm Data has been, and continues to be, the principal source for reliable tornado reporting in the U.S., and has recently become available online for searching severe weather events via the Internet. The Wisconsin Tornado Database (WTDB) was created from a variety of sources, including Storm Data, newspaper accounts, and other sources of information (see References chapter). It consists of several electronic documents containing accounts, descriptions, and data tables of tornado occurrences across the state. Its structure is ideal for examining and mapping the spatial and temporal aspects of Wisconsin tornadoes through electronic spreadsheets, statistical analysis programs, and Geographical Information Systems (GIS), and is the basis for this version of the data base, the Wisconsin Tornado Atlas.

The Wisconsin Tornado Atlas characterizes tornadoes over the period 1950-2005, through a variety of maps, charts, and tables. [Early tornadoes, prior to 1950, are not included because of the uncertainties in locating and describing them. However, historical tornado accounts (1844-1949) are listed in the WTDB Report No. GT-WTDB01 (Norgord, 2001)]. The atlas includes brief narratives relating the temporal and spatial aspects of tornadoes to the

many illustrations. Also included are chronological listings of each tornado event, for events by county, and for events by top five tornado outbreaks. A handy county lookup map is also included inside the back cover for reference.

The Wisconsin Tornado Atlas also includes a supplemental large format map, titled Wisconsin Tornado Tracks, 1950-2005. This map is a major part of this atlas and plots the paths of every known tornado over an attractive and detailed base map of the state. The map includes identification numbers that cross-reference each track location with the WTDB in the Atlas listings. Base information includes cities, towns, villages, township boundaries, major highways, water bodies, along with land elevation tints and a shaded relief backdrop that help to enhance the geographic nature of map. Several accompanying inset maps organize tornado tracks by intensity, time of year, and time of day.

Much literature regarding Wisconsin tornadoes as well as state and regional weather and climate histories, can be found online, in bookstores, and in reference collections at local libraries and many educational institutions. The Wisconsin State Historical Society archives, in particular, are a terrific resource for past tornado documentation and research.

Two highly recommended books include: A Tornado Climatology For Wisconsin (Knox and Norgord, 2000), published by the Wisconsin Geological and Natural History Survey, and Wisconsin’s Weather and Climate (Moran and Hopkins, 2002), published by the University of Wisconsin Press. The former provides a focused overview of tornado occurrences in Wisconsin, including an up-to-date discussion of appropriate safety rules. The later is a marvelous resource for Wisconsin weather facts and climate history, including a section devoted to summertime phenomena, including thunderstorms and tornadoes. Other suggested readings are listed in the References section of the atlas.

WISCONSIN TORNADO ATLAS This report describes the nature of tornadoes across Wisconsin over time, space, intensity, and human casualty, with a variety of maps, charts, and tables covering the period 1950 through 2005. DISTRIBUTION OF TORNADOES OVER TIME Yearly distribution of tornadoes and tornado days. Figure 4 and table 1 show the yearly number of tornadoes and tornado days since 1950. The significant increase in tornado reports during the first decade may be indicative of the undercount in tornado reports during

1950’s, at the time when public awareness of tornadoes was beginning to improve. Noteworthy is the year-to-year disparity of tornado occurrences. Some of the variation may be attributed to large-scale climate patterns, or even tornado outbreak events, such as the record number of 62 tornadoes that tracked across the state in 2005. Though large-scale weather patterns may have been suitable for severe weather that summer, the unusually high tornado count is enhanced by a record single day outbreak of 27 tornadoes on August 18 (see section on tornado outbreaks).

Annual distribution of tornadoes, by month. Figure 5 shows the monthly progression of tornadoes and tornado days throughout the year. Most tornadoes occur from late spring into early summer, reaching a maximum in June, then wane into September before becoming scarce by late autumn. Winter tornadoes are very rare, and there has never been a tornado recorded in Wisconsin during the month of February over the period 1950-2005. Daily distribution of tornadoes, by time of day. Figure 6 shows the distribution of tornadoes by time of day. The chart reveals that most tornadoes have occurred during the late

afternoon and early evening hours, even though they can happen at any time of the day. The devastating Barneveld tornado of June 7, 1984, for example, struck just before 1 A.M. (CDT), while many of the town’s people were asleep. DISTRIBUTION OF TORNADOES OVER SPACE Spatial distribution of tornado incidence. Tornadoes are small-scale weather disturbances that occur haphazardly across the land. Not only do their occurrences fluctuate from year-to-year, their spatial distribution varies dramatically from one decade to the next. To gain a better understanding of the overall spatial pattern of

tornadoes across the state it is helpful to summarize them by portion of land area, such as county, township, or other surface area measurement. With this in mind, an investigation into the spatial variation of tornadoes over the period 1950 through 2005 was carried out by first summarizing the number of tornadoes by county township, then calculating

their density (per square mile) based on a uniform 100 meter grid covering the entire state. The application of small grid sizes to describe tornado occurrences produces a remarkably detailed picture of tornado distribution (see figure 7). The map shows relatively large areas in the southern portion of the state having experienced the highest numbers of tornadoes, with scattered pockets of high occurrences across the western and central sections of the state. Tornado densities are much less across the north and northeastern sections where pockets of high occurrences fewer and farther apart. The highest densities of tornado

occurrences in the state are found across sections of Dodge, Fond du Lac, Grant, and Marathon Counties, and in the immediate area surrounding the Sauk-Dane-Columbia county line. The subsequently high county totals are an indication of their proximity to these high concentrations of tornadoes. Other bands of noticeably high tornado densities stretch from northwestern Barron to central Marathon Counties; western Grant County; southeastern Sauk and northern Dane Counties; southeastern Dane and southwestern Jefferson Counties; Juneau and Adams through Marquette, southern Waushara, Green Lake, Fond du Lac, and Dodge

Counties; and another stretching southeastward from northeastern Jefferson County to Milwaukee County. The lowest concentrations of tornadoes are found across the north and northeastern portions of the state, with pockets of low concentration scattered elsewhere. While it is difficult to establish particular reasons why tornadoes occur more or less frequently from one place to another, but it can be expected that the northern areas of the state will generally see less activity than areas to the south due to a shorter thunderstorm season and, therefore, less opportunities favorable for severe weather development. Wisconsin lies at the northern fringes of Tornado Alley, the northern parts of the state are that much farther removed from the geographical and meteorological components most favorable for tornado formation. Topography may also have an impact on the development of tornadoes. In Tornado Alley, for example, the uniqueness of geography plays an important role: The Rocky Mountains on the west and the warm Gulf of Mexico to the south provide perfect conditions for the development of severe weather across the openness of the Great Plains. However, mountainous or hilly topography may interfere with the air flow in and around tornado producing thunderstorms and supercells. [Supercells are thunderstorms capable of persisting for an hour or more due to powerful updrafts and sufficient vertical wind shear]. By this reasoning, the hilly topography of western and southwestern Wisconsin may actually have a disruptive impact on local thunderstorm development, thus contributing to a decrease of tornado activity across the area. Lakes Michigan and Superior can also affect the tornado occurrences, by either enhancing or suppressing thunderstorm development through mechanisms that are not fully understood. It is apparent from the track maps that, in the long term, moderating influences of the Great Lakes tend to decrease tornado occurrences along adjacent land areas. However, there is also some speculation that the high tornado occurrences in east-central portions of the state might be enhanced by a lake breeze pushing inland from Lake Michigan. This cooler and somewhat drier airflow boundary, comparable to a cool front, interacts with an unstable

atmospheric environment, thereby escalating thunderstorm development and intensity in the vicinity of the air boundary. There are also popular beliefs, or myths, that presume certain local geographical features, such as a hill, lake, ravine, or confluence of rivers, offer protection from tornadoes. Although they might seem believable and are often difficult to dispel, these assumptions are simply not true and should not be taken seriously. Spatial distribution of tornadoes, by month. Figures 8-13 show the bi-monthly distribution of tornado paths. The displaying of tornado tracks can provide valuable information about their spatial differences over monthly time scales. The tornado season typically begins during the month of April in Wisconsin, although tornadoes start to appear in March, especially across southeastern parts of the state. Tornadoes are most widespread and at their strongest levels in the months of May and June, except for the far northern and eastern sections of the state, and by July, virtually all areas have experienced their peak of tornado activity. During July and early August, the number of tornadoes begins to decrease. Tornadoes during this time are generally weaker, of shorter duration, and more often associated with severe thunderstorms moving from a northwesterly direction. In late August and September, the number of tornadoes declines steadily, however they tend to be stronger and generate longer tornado paths. After September, tornadoes become uncommon, developing primarily from an occasional strong weather system pushing warm moist air into the state. Very few tornadoes occur during late autumn and winter months. Spatial distribution of tornadoes, by time of day. Tornado tracks are mapped by hourly interval to illustrate their spatial characteristics with respect to the time of day in which they occur. Figures 14-19 show tornado tracks grouped by four-hour time periods in which they occurred. Most tornadoes occur between the hours of 12 P.M. and 8 P.M. (CST), with the main period of concentration between 4 P.M. and 8 P.M.

Spatial distribution of tornadoes, by county. Figure 20 shows the number of tornadoes summarized by county. County totals include tornadoes that have touched down within a county, or crossed into it from an adjacent county. The county distribution confirms that tornadoes generally occur more frequently

across the south-half of the state, with far fewer occurrences in northern and eastern counties. However, a few large counties, such as Dane, Chippewa, and Marathon, might tend to have more tornadoes because they encompass greater land area than smaller counties, like Pepin, or Kenosha. On the other hand, counties having higher populations can also affect the tornado

count simply because there are more people around who are more likely to see or feel the effects of a tornado. This may perhaps explain why some large counties with low populations, such as Ashland, or Sawyer, report relatively fewer tornadoes than some smaller counties having more people, such as Brown, or St. Croix (see figure 21 and table 2). Distribution of tornadoes, by direction of travel. Figure 22 shows the direction of travel over various points of a compass for the period 1950-2005. [Only tornadoes for which direction information is available are accounted for]. Both charts show that most tornadoes (about 36 percent) in Wisconsin travel from a southwest-to-northeast direction, and the majority of the remaining tornadoes move toward the east and southeast. This trend is also evident in the track maps, where the paths, drawn as lines, indicate the direction of travel beginning with, in most cases, the westernmost end of the path. The

track maps show a common southwest-to-northeasterly trend, with secondary, but noticeable, west-to-east variants. Tornado funnels themselves rotate counter-clockwise within their direction of travel. On very rare occasions do they spin clockwise, such as the West Bend tornado did on April 4, 1981. Tornado outbreaks. Occasionally, many tornadoes occur within a 24-hour period. Perhaps the most notorious outbreak event to hit Wisconsin was the 1965 Palm Sunday Outbreak of April 11-12. This outbreak spawned 51 tornadoes across several Midwestern states, causing a total 258 deaths, and 3,148 injuries. Wisconsin saw its share of 7 tornadoes that day, resulting in 3 deaths, and 84 injuries. Figure 23 shows the tracks of the top five ranked tornado outbreaks affecting Wisconsin since 1950. The largest outbreak to date occurred on August 18, 2005, when a record 27 tornadoes touched down in several counties across the southern half of the state, causing 1

death and 27 injuries. [Table A-4 of the Appendix contains a complete listing of the top five outbreak tornado events in Wisconsin]. DISTRIBUTION OF TORNADOES, BY INTENSITY The WTDB contains information on the intensity of a tornado event. The Fujita Scale, or “F-scale,” is the standard in describing

tornadoes by their intensity and is used to distinguish between weak tornadoes and strong tornadoes. F-scales are based on the extent of damage and flying debris at varying degrees of scale, and are usually determined by examining the varying degrees of damage in a tornado’s aftermath (see table 3). A tornado is typically assigned the scale of the highest rating along its damage path.

Page 21: Wisconsin Tornado Atlas 1950-2005

Wisconsin Tornado Atlas, 1950-2005 14

Figure 24 shows the distribution of tornadoes by their intensity. Generally, the number of tornadoes decreases with increasing intensity. However, as the chart indicates, most tornadoes fall within the F1 rating, and not F0. This discrepancy may lie in the fact that many weaker tornadoes did not get reported, unless they hit something or caused significant damage. It is also possible that the damage caused by some weak tornadoes was reported as “unspecified wind damage,” rather than an actual touchdown.

Figures 25-27 show the distribution of tornado tracks by F-scale. The maps show that the F0 and F1 grouping of tornadoes contain a

majority of brief touchdowns, suggestive of their shorter path lengths. F2 and F3 tornadoes are fairly evenly distributed throughout the state and tend to have longer track lengths (and longer duration) than their weaker counterparts. F4 and F5 tornadoes are so uncommon that it is difficult to determine any one area of maximum occurrence. Only two tornadoes of F5 strength have occurred between 1950 and 2005: The Barneveld tornado of June 7, 1984, and the Oakfield tornado of July 18, 1996. Historically, there have been at least three other F5 tornadoes in Wisconsin: One which struck on May 22, 1893, north of Darlington, Lafayette County; the May 18, 1898, tornado in northern Marathon

County; and the New Richmond tornado, St. Croix County, June 12, 1899 (WTDB, 2001). DISTRIBUTION OF TORNADO DEATHS AND INJURIES When viewed from a safe distance, tornadoes can be extraordinary events to watch. However, they are dangerous weather phenomena that can have tragic consequences, including property damage, injury, and even death. In Wisconsin, deaths and injuries by tornadoes have been reported in every month from March to November, but the majority of tornado casualties have occurred in June when the tornado season is at its peak. Fortunately, the number of people hurt by tornadoes has declined dramatically since the 1960’s, which may largely be attributed to modernization

techniques and educational efforts by the National Weather Service, emergency government agencies, and storm-spotter associations. Tornado deaths and injuries, by year. Figures 28-29 show the annual distribution of tornado deaths and injuries, and table 4 contains a monthly listing of all tornado deaths and injuries for the period 1950-2005. The strong disparity in casualties from year-to-year is by and large related to the number of strong tornado occurrences in that year, which, in turn, may be influenced by long-lived thunderstorm events, such as supercells, by outbreak events, or conversely, a lack of conditions suitable for tornado development. 1958 and 1984 are notable for high incidences in both deaths and

Page 23: Wisconsin Tornado Atlas 1950-2005

injuries. On the other hand, the years 1960 and 1993 had no deaths or injuries reported from tornadoes. Spatial distribution of killer tornadoes. Figure 30 shows the paths of killer tornadoes superimposed on a population density grid. It interestingly appears that the majority of track positions are closely aligned near areas of high population density. It is not unreasonable to assume that the likelihood for injury, and even death, from tornadoes is greater in more densely

populated areas than in lesser settled areas. It is highly important to note this because as more people move away from larger cities and into suburban and rural areas, as has been the trend in recent years, the societal vulnerability to the effects of tornadoes increases in terms of structural damage, economic cost, and human casualty. It can not be stressed enough that it is essential for people not to be complacent, and to understand and plan for tornadoes, and take precautions necessary to avoid catastrophe.

REFERENCES The Wisconsin Tornado Database (WTDB) developed from a separate tornado data base initially maintained by the Wisconsin Geological and Natural History Survey, and subsequently, by the Wisconsin State Climatology Office. Since 1988, sole maintenance of the tornado data base has been supported by Geographic Techniques, who has evolved it into the WTDB and the highly accessible documents it consists of today. The maps, charts, and tables found within the Wisconsin Tornado Atlas were constructed from WTDB information beginning with the year 1950, which is about the time when more reliable tornado spotting and reporting took place. [Tornado reporting before 1950 is generally less dependable. However, a few early accounts are well documented and provide vital information on past occurrences]. Original reference material for the earlier tornado data base, and subsequently, the WTDB, was obtained from Burley and Waite (1965), who list and describe tornado occurrences from 1844 through 1964. Prior to 1959, severe weather reports, including tornadoes, were documented in the Climatological Data National Summary, published annually by the U.S. government’s predecessor to the National Oceanic and Atmospheric Administration (NOAA), National Climatic Data Center (NCDC). In 1959, monthly national severe weather reports were published by the NCDC in the publication Storm Data, which are the base reference material for the WTDB. Tornado reports after 1997 were obtained online from the NCDC’s Storm Events internet website, which continues to be the major acquisition point for current tornado information today. Other than government reports, additional sources for tornado information include several references by Grazulis (1984, 1990, 1993, 1997). The Grazulis publications are good

sources for past strong and violent tornado accounts in the U.S., and are recognized for their accurate and thorough documentation. Additional sources for tornado include eyewitness accounts and newspaper reports. For analysis purposes, the WTDB was condensed into an electronic file consisting of raw tornado event data and track position coordinates (latitude, longitude). Data base information is suitable for examining the spatial and temporal characteristics of tornadoes when utilized with electronic spreadsheets, computer-aided mapping programs, and geographical information systems (GIS).

APPENDIX TORNADO EVENT LISTINGS, 1950-2005 The following tables contain chronological listings of Wisconsin tornadoes by single event, county events, and top five ranked outbreak event. Column heading descriptions and storm damage categories are shown in Table A-1. Wisconsin tornado listing, by single event (Table A-2). Column headings refer to (in order) the WTDB identification number*, year, month, day, beginning and ending times, duration, F-scale, track length, maximum track widths, direction of travel, number of deaths and injuries, and monetary property and crop damage (or loss). Blanks indicate that no information is available for that item in the listing. Wisconsin tornado listing, by county (Table A-3). Column headings for the county listings are similar to the event listings, however, not all fields shown. Note that some tornadoes are listed more than once if they cross more than one county. Tornado listing, by top five ranked outbreak event (Table A-4). Columns descriptions for the top five tornado outbreak listings, although modified, are basically the same: Outbreak ranking (first column), outbreak event sequence number (second column), and county(s) of occurrence (last column). *The Wisconsin Tornado Atlas begins with Tornado ID #273 (WTDB ID, year 1950). Early tornado event descriptions are listed in Geographic Techniques Report No. GT-WTDB01 (2001).
