Historical Weather And Climate Facts For Today

The cold weather of early June finally gave way to several days of 90
degree heat in Massachusetts, including a reading of 99 degrees at Salem.
(David Ludlum)
Six men at a rock quarry south of Winston-Salem NC sought shelter from a
thunderstorm. The structure chosen contained a quantity of dynamite.
Lightning struck a near-by tree causing the dynamite to explode. The men
were killed instantly. (The Weather Channel)
Twelve inches of hail broke windows and roofs, and dented automobiles,
causing more than fourteen million dollars damage. The storm plowed 200
miles from Kingmand County KS into Missouri, with the Wichita area hardest
hit. It was the most disastrous hailstorm of record for the state of
Kansas. (David Ludlum)
Thunderstorms produced a swath of hail 60 miles long and 3.5 miles wide
through parts of Hand, Beadle, Kingsbury, Miner and Jerauld counties in
South Dakota. Poultry and livestock were killed, and many persons were
injured. Hail ten inches in circumference was reported at Huron SD. (The
Weather Channel)
