...ON THIS DATE IN WEATHER HISTORY...

In 2010, huge severe thunderstorms hammered parts of
Central South Dakota with destructive hail.  Many
hailstones were 6 to 8 inches in diameter! The largest
hailstone reached an incredible 8 inches in diameter and
weighed 1.94 pounds, making it the largest and heaviest
hailstone in United States history.  The humongous
hailstone landed in Vivian, located about 15 miles south
of Pierre.  No doubt, the horrendous hail punched holes
in many roofs and patios.  It is believed that the
incredibly intense updrafts associated with the Vivian
severe thunderstorm ranged from 160 to 180 mph! These
extremely dangerous thunderstorms also produced 80 to 90
mph winds and 2 tornadoes.  Minnesota has been referred
to as the state with 10,000 lakes.  In 1987, violent
thunderstorms practically turned Minneapolis St.  Paul
into the Twin Cities with 10,000 lakes.  Around 10 inches
of rain inundated Minneapolis in six and a half hours, of
which 5.26 inches swamped the city in only two hours.
The flash flooding was obviously appalling as it turned
streets into rushing rivers, parking lots into lakes, and
storm sewers into spouting geysers.  The flooding caused
$21.3 million damage and 2 people drowned in the
disaster.  In addition, an F3 tornado struck nearby Maple
Grove, causing an additional $5 million damage.  Parts of
Southwest Minnesota were hammered by a barrage of
baseball sized hail.
