2004: Gusty Mono Winds blew across the southern Sierra with gusts clocked as high as 93 mph.
Numerous trees blew down near El Portal and Foresta and property damage occurred in Oakhurst and Ponderosa Basin.
Overall 3600 customers lost power in the mountains.
2004: A mid and upper level trough dug southward from the northern Rockies on November 19th and by the evening of the 20th formed an upper low over northern Nevada which eventually closed off and moved towards southern California by the morning of the 21st.
This low remained over southern California into the 22nd.
Most of the snow fell across the area on the 21st into the 22nd. There were three main areas of heavy snow that fell from this storm.
These were in the Morongo Basin area of California, mainly in the town of Yucca Valley, the Spring Mountains of southern Nevada and the higher elevations of central Mohave County in Arizona.
Snow fell as low as 2000 feet in San Bernardino County and as low as 3400 feet in the Spring Mountains.
Specific totals included 18" in the Sky Harbor area in Yucca Valley at 3900 feet in elevation, 12" in Yucca Valley around 3500 feet in elevation and 2" in Joshua Tree.
On Mt. Charleston (NW of Las Vegas, NV), totals ranged from 23" in Kyle Canyon at 7450 feet to 36" at the ski resort in Lee Canyon.
In northwest Arizona, 24" fell at the top of Hualapai Mountain with 12.3" measured at Diamond M Ranch and 2" recorded in Kingman, AZ.
Snowfall totals over a foot in these areas are significant amounts in the middle of winter, let alone so early in the season.
2004: Thundersnow started on the evening of 11.20 in the upper desert and snow continued until 11.22.
Widespread snow reports of two feet with drifts to three feet came from Wrightwood, Lake Arrowhead, Big Bear and the Palm Springs Tramway (at 8,500 feet).
The snow level was as low as 1,000 feet.
18"-20" of snow fell in foothills south of YuccaValley, 14" fell in Phelan, 9"-12" in Hesperia and Apple Valley, 9" in Yucaipa and Calimesa and up to 3" throughout the southern Inland Empire.
Tree damage resulted in lower elevations, which caused house damage and power outages.
Snow lined I-10 near Calimesa for a few days following the end of the snow.
On this day the storm brought wind gusts to 84 mph to Fremont Canyon and 62 mph to northern San Bernardino.
2002: Fresno reached a high of 81° F, making it the latest 80° F or better high temperature on record.
1977: Saint Helena received 5.19" of rain -- a record for the month.
1972: Santa Barbara hits 105° F, establishing an all-time high for the month.
1967: A moist subtropical storm system that started on 11.18 ended on this day.
14"+ of precipitation fell in the mountains above LA, 7.96" fell in LA.
Flooding was called the "worst since 1934."
Two were killed.
Flash flooding and mud slides resulted.
400 were stranded in the mountains due to closed highways.
On this day 0.51" fell in San Diego in 10 minutes, the greatest 10 minute rainfall on record.
1957: Extremely destructive Santa Ana winds started on this day and ended on 11.22.
Winds produced a 28,000 acre brush fire on a 40-mile front west of Crystal Lake.
People were ordered off the streets in some areas due to flying debris.
12 of 33 passengers on an airplane over Ontario were hurt by a downdraft in extreme turbulence.
Paint was completely stripped off of windward sides of four cars stalled in a Fontana sandstorm.
1924: It was 97° F in Riverside, the highest temperature on record for November.
This also occurred on 11.2.1997.
1900: 12" of snow fell at Cedarville (in Surprise Valley, Modoc Co.).
1884: A heavy winter storm brought 4" of rain to LA, and 6" to Cajon Pass, where newly laid railroad track was washed out and numerous mud slides occurred.
