2011: Clearing skies and wet grounds in the wake of a departing Pacific low pressure system led to the development of dense fog across the western Arizona deserts during the morning hours on December 15th.
Many locations along the lower Colorado River Valley and across the southwest Arizona deserts observed dense fog which lowered visibilities to near zero miles, beginning during the early morning hours.
By noon, the fog had mostly dissipated.
2002: A strong cold front moved through the region and winds associated with the cold front blew down hundreds of trees and thousands of branches across northeast California and western Nevada.
The roof was blown off an apartment complex in Carson City, NV.
The strongest wind gusts were close to 100 mph.
1987: Strong Santa Ana winds all along the base of the San Gabriel and San Bernardino Mountains.
In San Bernardino, winds gusted to 60 mph.
Gusts up to 80 mph were reported around San Bernardino.
One was injured when a tree fell on a truck.
80 power poles were blown down within a half mile stretch in Fontana and Rancho Cucamonga.
Downed tree limbs damaged cars, homes and gardens.
Power poles and freeway signs were damaged.
A parked helicopter was blown down a hillside in Altadena.
Avocado crop damage from winds hit Fallbrook.
Over most of San Diego County the dry air led to low temperatures where the wind didn't blow.
It was 13° F in Mt. Laguna, 18° F in Campo, 23° F in Valley Center, 24° F in Escondido, 28° F in El Cajon, 31° F in Del Mar, and 33° F in Chula Vista.
1972: Fresno once again reaches only 32° F for a high temperature.
This was the only other day on record in any month with a freezing high temperature.
1967: A period of snow in the mountains 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.
The cold air following the initial front produced one of the coldest days on record on this day.
It was the coldest day on record in Big Bear Lake, where the high temperature was 15°.
One freezing death resulted, numerous schools and highways were closed, transportation was disrupted and there were power outages.
Heavy rain that began on 12.12 ended on 12.15.
There were two drowning deaths in San Diego County.
1948: 36" of snow fell at Tahoe City (west shore Lake Tahoe).
1932: Snow fell for a 4 day period ending on this date in Las Vegas.
Charles "Pop" Squires measured 7" on Fremont Street.
1925: Redwood City received 2.67" of rain.
1920: Frost was observed at the bay side in San Diego.
