Historical Weather And Climate Facts For Today

The famous "Lower Great Lakes Storm" occurred. Southwesterly winds were at
hurricane force for five hours, driving lake waters into downtown Buffalo
NY. The storm drowned 200 persons. (David Ludlum)
Rain changed to a record early season, heavy wet snow over the southern
mountains of West Virginia. Leaves were still on trees, resulting in the
worst forest disaster since the fires of 1952 and 953. One to two feet of
snow fell near Summersville and Richwood. (19th-20th) (The Weather Channel)
Thunderstorms deluged the town of Odem TX (located 15 miles northwest of
Corpus Christi) with 25 inches of rain in just three and a half hours. Most
businesses in Odem were flooded, as were 1000 homes in nearby Sinton. (The
Weather Channel)
A cold front brought rainshowers to parts of the central U.S., and ushered
cool Canadian air into the Great Plains Region. Daytime highs were only in
the 30s in North Dakota and eastern Montana. (The National Weather Summary)
Thunderstorms produced high winds in eastern Colorado, with gusts to 63 mph
reported at La Junta. (Storm Data) (The National Weather Summary)
Record breaking snows fell across northern and central Indiana. Totals
ranged up to 10.5 inches at Kokomo, and 9.3 inches was reported at
Indianapolis. The 8.8 inch total at South Bend was a record for the month
as a whole. Up to seven inches of snow fell in extreme southern Lower
Michigan, and up to six inches fell in southwestern Ohio. The heavy wet
snow downed many trees and power lines. Half the city of Cincinnati OH was
without electricity during the morning hours. Temperatures dipped below
freezing across much of the Great Plains Region. Twenty cities, including
fourteen in Texas, reported record low temperatures for the date. North
Platte NE reported a record low of 11 degrees. In Florida, four cities
reported record high temperatures for the date. The record high of 92
degrees at Miami also marked a record fourteen days of 90 degree weather in
October, and 116 such days for the year. (The National Weather Summary)
