Historical Weather And Climate Facts For Today

SEPTEMBER 23RD
HISTORIC WEATHER EVENTS
...1815...
One of the greatest hurricanes to strike New England made landfall at Long
Island and crossed Massachusetts and New Hampshire. It was the worst
tempest in nearly two hundred years, equal to the hurricane which struck in
1938, and one of a series of severe summer and autumn storms to affect
shipping lanes that year. (David Ludlum)
...1904...
The temperature at Charlotteburg NJ dipped to 23 degrees, the coldest
reading of record for so early in the autumn for the state. (The Weather
Channel)
...1983...
A thunderstorm downburst caused a timber blowdown in the Kaibab National
Forest north of the Grand Canyon. Two hundred acres were completely
destroyed, and scattered destruction occurred across another 3300 acres.
Many trees were snapped off 15 to 30 feet above ground level. (The Weather
Channel)
...1987...
Autumn began on a rather pleasant note for much of the nation. Showers and
thunderstorms were confined to Florida and the southwestern deserts. Warm
weather continued in the western U.S., and began to spread into the Great
Plains Region, but even in the southwestern deserts readings remained below
100 degrees. (The National Weather Summary)
...1988...
Thunderstorms developing along a cold front in the south central U.S.
produced severe weather in Oklahoma during the afternoon and early evening
hours. Thunderstorms produced softball size hail near Noble and Enterprise,
and baseball size hail at Lequire and Kinta. A tornado near Noble OK
destroyed a mobile home injuring one person. (The National Weather Summary)
(Storm Data)
...1989...
Seventeen cities in the north central U.S. reported record low temperatures
for the date, including Devils Lake ND with a reading of 22 degrees.
Jackson KY reported a record low of 41 degrees during the late afternoon.
Strong northwesterly winds ushering cold air into the central and
northeastern U.S. gusted to 55 mph at Indianapolis IND. Winds along the
cold front gusted to 65 mph at Norfolk VA, and thunderstorms along the cold
front deluged Roseland NJ with 2.25 inches of rain in one hour. The
temperature at Richmond VA plunged from 84 degrees to 54 degrees in two
hours. Snow and sleet was reported at Binghamton NY. (Storm Data) (The
National Weather Summary)
...2006...
A slow-moving storm system brought torrential rains to Kentucky on 
September 22 and 23, 2006, resulting in widespread flooding.  Eight people 
were killed in the state. It was the worst general flood since the March 
1997 flood.  It was the deadliest weather event in this area since seven 
people were killed in the flood of March 1-2, 1997, and the Super Outbreak 
of tornadoes on April 3, 1974 when 72 lives were lost.
