2010: A very wet period began 12/17 and continued through 12/22 as strong westerly flow across the Pacific tapped a pool of deep subtropical moisture near Hawaii, resulting in days of moderate to heavy rainfall.
4"-12" of rain fell in the coastal and valley areas over six days, 12"-28" in the mountains, up to 9" in the high desert and less than 4" in the lower desert.
Major landslides and flash flooding impacted the communities of Laguna Beach, Apple Valley, along the Whitewater Channel in the Coachella Valley near Palm Springs, Highland, Corona, Loma Linda, La Jolla, and the city of San Diego from 12/21 to 12/22.
Qualcomm Stadium was flooded, but was miraculously drained and prepared for the Poinsettia Bowl held there on 12/23.
Heavy wet snow accumulated above 6500 feet with amounts over 6" and as much as 24" above 7500 feet.
2010: Record breaking rainfall occurred in Bakersfield and Hanford due to a series of systems tapping into a subtropical moisture source, affecting mainly the southern half of the Hanford Warning/Forecast Area, especially Kern County.
The old record in Bakersfield was 0.3" in 1921 for this date.
2008: A snowstorm of a magnitude that hasn't occurred since 1979 descended on the mountains and high deserts from 12.15 to this day.
Impressive snow totals include 54" at Big Bear, almost 36" at Wrightwood, 20" at Pinon Hills, and 16" at Hesperia, Idyllwild and Julian.
Interstate 15 was closed from San Bernardino to the Nevada state line for many hours.
2008: A storm system moving inland from the Pacific tracked across southern California spreading abundant moisture over low-level cold air resulting in a widespread accumulating snow in the Mojave Desert and in the Kern County mountains.
Snowfall totals on the desert floor included 2.0" at Rosamond, 5.0" at Randsburg and 6..0" at California City with 10.0" of snow in the Kern County mountains at Frazier Park.
1997: A period of Santa Ana winds started on this day and ended on 12.21.
Gusts of 60 mph were reported at Rialto.
Gusts of 67 mph were reported at Idyllwild and below Cajon Pass.
One was killed.
The winds downed trees, caused widespread wind damage and contributed to a fire.
1984: A major snowstorm that started on this day and ended on 12.19 brought up to 16" to the mountains and upper deserts, including 13" to Lancaster.
Edwards AFB and Interstate 5 (from Castaic to the San Joaquin Valley) were both closed.
1978: 23" of snow fell at Tahoe City (west shore Lake Tahoe), with 22" at Truckee.
1970: Priest Valley received 3" of snowfall.
1970: A series of storms brought heavy rain and snow to the region starting on 12.17 and ending on 12.22.
7.03" of precipitation was recorded in Palomar Mountain, 6.93" in Lytle Creek, 6.35" in Lake Arrowhead, 5.38" in Idyllwild, 4.72" in Big Bear Lake, 2.81" in San Bernardino, 2.67" in Santa Ana, 2.27" in Riverside, and 1.84" in San Diego.
Several roads were flooded and washed out in the northern Inland Empire, exacerbated by the extensive burn areas from earlier in the fall.
Snowfall amounts were 32" in Idyllwild, 28" in Big Bear Lake, 26" in Palomar Mountain, and 24" in Lake Arrowhead.
1967: A winter storm brought heavy snow to the Sierra, even as low as the 4,000 foot level from the 18th-20th of December.
Yosemite Valley measured 18.6" and 22" fell at Grant Grove.
1967: A period of snow began on 12.13 and ended on 12.19.
The entire period of snow brought 50" to Mt. Laguna, 38" in Idyllwild, 24" to Palomar Mountain, and 12"-18" to the higher elevations.
One freezing death resulted, numerous schools and highways were closed, transportation was disrupted and there were power outages.
1908: Bakersfield reached a high of only 35° F, setting a record low maximum for the date.
This was one of 10 days that December here to have a high of 40° or lower, a record for the month of December.
1908: The morning low temperature at Reno, NV, was -1° F.
1880: Heavy rains caused San Diego streets to flood.
