...Here is the complete story on what happened during the very early morning hours on June 8, 1984...

AN AREA OF LOW PRESSURE GATHERED STRENGTH ACROSS THE UPPER MIDWEST DURING THE AFTERNOON OF JUNE 7 1984. MOISTURE...SHEAR...AND INSTABILITY HELPED TO SPAWN TORNADOES OF THE F1 TO F3 VARIETY ACROSS NORTHERN MISSOURI...NORTHEASTERN KANSAS...SOUTHERN AND NORTHWESTERN IOWA...AND SOUTHEASTERN MINNESOTA.

AS THE ATMOSPHERE BECAME MORE UNSTABLE BY THE LATE EVENING HOURS...A CLUSTER OF THUNDERSTORMS DEVELOPED OVER SOUTHWESTERN WISCONSIN. THE FIRST TORNADO WAS NOTED TO SPIN UP IN THE BELMONT AREA AT 1230 AM CDT JUNE 8. THIS TORNADO TRAVELED TO MINERAL POINT WHERE IT DISSIPATED. THIS TORNADO WAS RECORDED AS AN F2 ON THE FUJITA SCALE.

AT 1241 AM CDT A SECOND TORNADO SPUN UP SOUTH OF RIDGEWAY AND INTENSIFIED RAPIDLY AS IT CRASHED THROUGH BARNEVELD IN IOWA COUNTY. THE VIOLENT TORNADO CONTINUED HEADING NORTHEAST INTO BLACK EARTH BY 107 AM CDT. THE TORNADO FINALLY DISSIPATED AT 140 AM CDT JUST SOUTHEAST OF LODI...NEAR THE COLUMBIA/DANE COUNTY BORDER.

AFTER A 36 MILE LONG PATH FOR 59 MINUTES...93 HOMES WERE COMPLETELY DESTROYED...64 OTHERS WERE DAMAGED. SEVENTEEN OF THE EIGHTEEN BUSINESSES AND PUBLIC FACILITIES IN THE TOWN OF BARNEVELD WERE ALSO DESTROYED. NEARLY 90 PERCENT OF THE TOWN WAS COMPLETELY DEVASTATED. AT ONE POINT IN TIME...THE WIDTH OF THE TORNADO DAMAGE WAS NEARLY 400 YARDS WIDE.

DESPITE THE TORNADO PROPAGATING THROUGH THE TOWN IN THE MIDDLE OF THE NIGHT...IN COMBINATION WITH THE MYTH CIRCULATING AROUND THE TOWN THAT NO TORNADOES COULD EVER SURVIVE THE HIKE UP THE BLUE MOUND...9 PEOPLE DIED AND 197 OTHERS WERE INJURED. 25 MILLION DOLLARS IN DAMAGE WAS CALCULATED. IT WAS LATER DETERMINED BY TED FUJITA THAT THE BARNEVELD TORNADO WAS INDEED AN F5...THE HIGHEST LEVEL ON THE FUJITA TORNADO SCALE.

THE CLUSTER OF THUNDERSTORMS THAT SPAWNED THE BARNEVELD TORNADO HAD ALSO SPAWNED OTHER TORNADOES ACROSS SOUTHERN WISCONSIN LATER THAT NIGHT. OTHER TORNADOES INCLUDED...

...THE F2 ARLINGTON /COLUMBIA CO./ TORNADO...
...THE F2 DEFOREST /DANE CO./ TORNADO...
...THE F3 MARKESAN /GREEN LAKE CO./ TORNADO...
...THE F1 COLUMBUS /DODGE CO./ TORNADO...
...THE F2 BEAVER DAM /DODGE CO./ TORNADO...

ALL IN ALL...9 PEOPLE WERE KILLED AND 200 OTHERS WERE INJURED DURING THE ENTIRE TORNADO OUTBREAK. TOTAL DAMAGE WAS CALCULATED AT 40 MILLION...25 OF THAT 40 MILLION OCCURRED IN BARNEVELD ALONE.

...A COMPREHENSIVE SUMMARY OF THE FUJITA SCALE...

...WIND SPEEDS ARE ESTIMATED FROM DAMAGE SURVEYS...

F1...40-72 MPH
F2...73-112 MPH
