HISTORIC WEATHER EVENTS
...1761...
A hurricane struck southeastern New England. It was the most violent in
thirty years. Thousands of trees blocked roads in Massachsuetts and Rhode
Island. (David Ludlum)
...1843...
"Indian Summer" was routed by cold and snow that brought sleighing from the
Poconos to Vermont. A foot of snow blanketed Haverhill NH and Newberry VT,
and 18 to 24 inches were reported in some of the higher elevations. Snow
stayed on the ground until the next spring. (22nd-23rd) (Sandra and TI
Richard Sanders - 1987) (The Weather Channel)
...1987...
Thirteen cities in the southeastern U.S. reported record low temperatures
for the date. It marked the sixth record low of the month for Greer SC and
Columbia SC, and the ninth of the month for Montgomery AL. Showers and
thunderstorms deluged Corpus Christi TX with five inches of rain.
Winnemucca NV reported their first measurable rain in ninety-two days,
while Yakima WA reported a record 96 days in a row without measurable
rainfall. (Storm Data) (The National Weather Summary)
...1988...
Denver CO reported their first freeze of the autumn, and Chicago IL
reported their first snow. In Texas, afternoon highs of 93 degrees at
Austin and San Antonio were records for the date. (The National Weather
Summary)
...1989...
A storm moving out of the Gulf of Alaska brought rain and high winds to the
Central Pacific Coast Region. High winds in Nevada gusted to 67 mph at
Reno, and thunderstorms around Redding CA produced wind gusts to 66 mph.
Locally heavy rains in the San Francisco area caused numerous mudslides,
adding insult to injury for earthquake victims. (The National Weather
