[californiadisasters] On This Date In California Weather History (September 21)



2013: An early season cold storm brought 3-5" of snow in the high country in Yosemite National Park, including near Tuolumne Meadows and Tioga Pass.
Numerous thunderstorms brought locally heavy rain to the Sierra Nevada and foothills; isolated
thunderstorms also developed over the San Joaquin Valley from Fresno County
and northward.
A record high wind gust of 36 mph for the month of September was set at Fresno-Yosemite
International Airport.
Otherwise, blowing dust and gusty winds occurred throughout much of the San Joaquin
Valley with gusts around 40 mph in several locations.

1994:
A series of thunderstorms moved through the Yuma, AZ, area during the early morning hours.
Rainfall amounts up to 2.5" led to the flooding of 4 homes about 8 miles south of Yuma.
Several roads in Somerton, AZ, and U.S. 95 about eight miles northeast of Yuma were closed due to flooding.
2 cars were pushed off U.S. 95 at Fortuna, AZ.
Also, localized strong winds knocked over at least 5 power poles on County Road 14 in Somerton.
The Yuma County Extension Agent estimated crop damages from the flood approaching $1 million, mainly cotton.

1983:
A thunderstorm downdraft generated powerful winds that toppled and twisted 35 high voltage power lines near Buttonwillow.
The thunderstorms were fueled by moisture associated with the remnants of Tropical Storm Manuel.

1983: Northward moving Hurricane Manuel dissipated off the west coast of northern Baja California producing up to 3 inches of rainfall in the southern mountains and deserts on 9.20 and on this day.
This occurred during the strong El Niño of 1982-83.

1968: It was 26° F in Idyllwild, the lowest temperature on record for September.
This also occurred on 9.20.65, 9.23.1945, and 9.24.1945.

1960: Pinnacles National Monument had a low temperature of 35° F.

1952: A west-northwestward moving tropical storm southwest of Baja California dissipated.
Moisture from this storm resulted in rainfall of up to two inches in the mountains and deserts starting on 9.19 and ending on this day, with most falling on 9.19.
This occurred during the El Niño of 1951-52.

1939: A heat wave that started on 9.18 and ended on 9.22 preceded the arrival of a tropical storm called "El Cordonazo."
High temperature records of more than 95° F occurred at San Diego each day, with the highest temperature reaching 106° F on this day.
On this day it was 111° F in Santa Ana, the highest temperature on record for September, and the second highest temperature on record.
This also occurred the next day on 9.22.
A tropical cyclone moving northwestward, just off the west coast of Mexico, moved into southern Baja California and dissipated.
The moisture from this tropical cyclone generated rainfall of up to 3" in the deserts and mountains starting on 9.19 and ending on this day.

1928: Bakersfield had a record high for the date of 104° F.
This is the oldest record for Meadows Field in Bakersfield.

1895: Daily record lows set at Reno, NV, with 24° F and Carson City, NV, at 19° F.
