Historical Weather And Climate Facts For Today

APRIL 24TH
HISTORIC WEATHER EVENTS
...1899...
Two women and one son lived to tell the story of being picked up by a
tornado and carried more than a fourth of a mile, flying far above the
church steeples, before being gently set down again. The young boy and one
of the ladies said they had the pleasure of flying alongside a horse. The
horse "kicked and struggled" as it flew high above, and was set down
unharmed about a mile away. (The Weather Channel)
...1908...
Severe thunderstorms spawned eighteen tornadoes over across the Central
Gulf Coast States claiming the lives of 310 persons. The state of
Mississippi was hardest hit. A tornado near Hattiesburg MS killed 143
persons and caused more than half a million dollars damage. Four violent
tornadoes accounted for 279 of the 310 deaths. The deadliest of the four
tornadoes swelled to a width of 2.5 miles as it passed near Amite LA. The
tornado also leveled most of Purvis MS. (David Ludlum) (The Weather
Channel)
...1925...
Louisville's and Bowling Green's warmest April temperature: 91 and 96 
degrees, respectively. Also, Lexington's earliest 90 degree temperature (90 
degrees). (NWS Louisville)
...1980...
Three of eight helicopters were damaged in a sandstorm during a 
failed-attempt to rescue 52 American hostages held in Iran. The hostages 
were later released on January 20, 1981.
...2005...
The latest measurable snowfall on record occurred across parts of Kentucky 
last year. The snow was the result of cold air and moisture wrapping around 
an area of low pressure located over the northeast United States. 
Accumulating snow was mainly confined to the ridgetops and higher 
elevations of extreme east Kentucky but at least a few flakes were reported 
just about everywhere. Some amounts reported from across eastern and 
central Kentucky  include...0.6 inches in Booneville...1.0 inch at 
Jeremiah...1.2 inches at the Jackson Weather Office...1.5 inches at 
Cumberland...4.0 inches at Lynch...and 5.0 inches at Closplint. (NWS Jackson)
