THIS DAY IN WEATHER HISTORY:
2013: A cold and dry air mass produced a significant freeze in all areas away from the coast on this day and 1/13. Low temperatures dropped to the 30s near the coast, 20s inland and in the low deserts, and the low teens in the high desert, which caused some water pipe damage. A frigid -8 degrees was recorded at Big Bear City – Shay Meadows.

2009: Santa Ana winds and a strong ridge of high pressure brought unseasonable warm weather to the region. The low temperature in Santa Ana only dropped to 73° (a record for January). This reading was 26 degrees higher than the average low temperature and three degrees higher than the average high temperature.

2007: Three inches of snow fell in Yucaipa. One inch fell in Highland and Redlands. Trace amounts of snow fell as low as 500 feet in elevation in the Inland Empire.

2000: A funnel cloud was observed 12 miles west of Mission Beach. 1997: A storm that started on this day and ended on 1/13 gave the coastal areas and valleys one to three inches of rainfall. Snow continued in the mountains and as of 1/15, 18 inches of snow had fallen at Mt. Laguna. Generally, 18 inches to three feet of snow was reported above 2500 feet. The ski resort at Snow Valley remained open until 5/18, the latest in its 78 year history. Dime size hail up to one foot deep covered a small area in Buena Park and Cypress. 13 illegal immigrants died from Dense fog hit Yorba Linda on this day in 2014. exposure near Pine Valley. On this day a waterspout was reported two miles southwest of Lindbergh Field – San Diego and came ashore as a tornado at Shelter Island, causing damage to the resort.

1996: Elsinore topped out with an afternoon high temperature of 91°, a record for January. This is one of only three times the city has seen a 90 degree reading in January since records began in 1897.

1993: A very wet series of storms that began on 1/6 and ended on 1/19 produced 20 to 50 inches of precipitation in the mountains and up to 12 inches at lower elevations over a two week period. It was one of the longest periods of consecutive days of rain on record (14) and measurable rain fell nearly every day from 1/2 to 1/19. Flooding and flash flooding, mud slides, etc., resulted.

The lowest temperatures on record occurred a few days later: 0° on 1/16/1949 and -1° on 1/17. 43 inches of snow fell at Palomar Mountain from 1/10 to 1/13, the greatest snowfall on record. A strong offshore wind developed after a cold winter storm. A 49 mph gust was observed in LA.
