OCTOBER 20TH
HISTORIC WEATHER EVENTS
...1770...
An exceedingly great storm struck eastern New England causing extensive
coastal damage from Massachusetts to Maine, and the highest tide in 47
years. (David Ludlum)
...1983...
Remnants of Pacific Hurricane Tico caused extensive flooding in central and
south central Oklahoma. Oklahoma City set daily rainfall records with 1.45
inch on the 19th, and 6.28 inches on the 20th. (17th-21st) (The Weather
Channel)
...1987...
Cold arctic air invaded the Upper Midwest, and squalls in the Lake Superior
snowbelt produced heavy snow in eastern Ashland County and northern Iron
County of Wisconsin. Totals ranged up to 18 inches at Mellen. In the
western U.S., the record high of 69 degrees at Seattle WA was their
twenty-fifth of the year, their highest number of record highs for any
given year. Bakersfield CA reported a record 146 days in a row with daily
highs 80 degrees or above. (The National Weather Summary) (Storm Data)
...1988...
Unseasonably warm weather continued in the western U.S. In California,

...1989...
Forty-nine cities reported record low temperatures for the date as readings
dipped into the 20s and 30s across much of the south central and
southeastern U.S. Lows of 32 degrees at Lake Charles LA and 42 degrees at
Lakeland FL were records for October, and Little Rock AR reported their

thunderstorms brought heavy rain to parts of the northeastern U.S. Autumn
leaves on the ground clogged drains and ditches causing flooding. Up to
4.10 inches of rain soaked southern Vermont in three days. Flood waters
washed 600 feet of railroad track, resulting in a train derailment. (The
