Weather History...



/////////////////////////
JUNE 22ND...HISTORIC WEATHER EVENTS
...1947...
Twelve inches of rain fell in forty-two minutes at Holt MO establishing a
world rainfall record. That record was tied on January 24-25, 1956, at the
Kilauea Sugar Plantation in Hawaii, as their state record was established
with 38 inches of rain in 24 hours. (The Weather Channel)
...1972...
Hurricane Agnes deluged Pennsylvania and New York State with torrential
rains resulting in the most costly flood in U.S. history. In the Middle
Susquehanna Valley of Pennsylvania, 24 hour rainfall amounts were generally
8 to 12 inches, with up to 19 inches in extreme southwestern Schuylkill
County. At Wilkes-Barre PA the dike was breached destroying much of the
town. Flooding resulted in 117 deaths and 3.1 billion dollars damage.
(David Ludlum)
...1981...
A young woman from Lubbock TX was struck by lightning. The bolt of
lightning struck just above her right shoulder near her neck, and passed
right to left through her body, tearing her warm-ups, causing her tennis
shoes to explode, and lifting her two feet into the air. (The Weather
Channel)
...1992...
Record cold prevailed in the eastern U.S. with 67 low temperature records for 
the date tied or broken.  Indianapolis, Indiana dipped to 37 degrees to set a 
new all-time record low temperature for June and the coldest summer temperature 
ever.  In sharp contrast, it was a furnace in the Pacific Northwest with Eugene 
and Medford, Oregon setting new all-time record high temperatures for June with 
102 and 111 degrees, respectively.
