Weather History...



SEPTEMBER 30TH
HISTORIC WEATHER EVENTS
...1959...
Three tornadoes spawned by the remnants of Hurricane Gracie killed 12
persons at Ivy VA. (The Weather Channel)
...1970...
A nineteen month drought in southern California came to a climax. The
drought, which made brush and buildings tinder dry, set up the worst fire
conditions in California history as hot Santa Anna winds sent the
temperature soaring to 105 degrees at Los Angeles, and to 97 degrees at San
Diego. During that last week of September whole communities of interior San
Diego County were consumed by fire. Half a million acres were burned, and
the fires caused fifty million dollars damage. (David Ludlum)
...1977...
The temperature at Wichita Falls TX soared to 108 degrees to establish a
record for September. (The Weather Channel)
...1986...
Thunderstorms, which had inundated northern sections of Oklahoma with heavy
rain, temporarily shifted southward producing 4 to 8 inches rains from
Shawnee to Stilwell. Baseball size hail and 80 mph winds ripped through
parts of southeast Oklahoma City, and thunderstorm winds caused more than
half a million dollars damage at Shawnee. (Storm Data)
...1987...
Afternoon thunderstorms in Michigan produced hail an inch in diameter at
Pinckney, and wind gusts to 68 mph at Wyandotte. A thunderstorm in northern
Indiana produced wet snow at South Bend. Seven cities in the northwestern
U.S. reported record high temperatures for the date, including readings of
98 degrees at Medford OR and 101 degrees at downtown Sacramento CA. (The
National Weather Summary) (Storm Data)
...1988...
Unseasonably warm weather prevailed over Florida, and in the western U.S.
The afternoon high of 94 degrees at Fort Myers FL was their tenth record
high for the month. Highs of 98 degrees at Medford OR and 99 degrees at
Fresno CA were records for the date, and the temperature at Borrego Springs
CA soared to 108 degrees. (The National Weather Summary)
...1989...
Thirteen cities reported record high temperatures for the date, as readings
soared into the upper 80s and 90s from the Northern and Central High Plains
Region to Minnesota. Bismarck ND reported a record high of 95 degrees, and
the temperature reached 97 degrees at Broadus MT. Afternoon thunderstorms
developing along a cold front produced wind gusts to 60 mph at Wendover UT.
