... On this date in weather history...

In 2010... monstrous severe thunderstorms bombarded 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 horrific 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 unleashed 80 to 90
mph winds and produced 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 2 hours. The flash flooding was... of
course... horrific... 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 bombarded by baseball sized
hail.
