Warmer and drier conditions will prevail through at least Tuesday, with periods of gusty northeast winds near the coastal slopes of the mountains. A little cooler for coastal and valley areas on Wednesday as the offshore weakens. Offshore flow returns and may be stronger Thursday into Friday with very low humidity. Temperatures will be well above average all week long with sunny days and clear nights. Cooler next weekend with higher humidity as onshore flow spreads some marine air inland.
United States Overview:
Rain and thunderstorms expected across the central and eastern U.S., with severe weather possible. Heavy rain continues through Tuesday for the Pacific Northwest.
A very wet and dynamic series of storms started on 1/18 and ended on 1/22. Rainfall ranged from two to four inches in the deserts, to four to eight inches west of the mountains, to six to 12 inches on the coastal slopes. Widespread flooding resulted across the region. Snowfall of 40 to 60 inches was reported at the higher resorts, with up to seven feet at the highest ski resorts. On this day Big Bear reported 29 inches of snow, a daily record for the month. Some of the worst flash flooding occurred in the high desert on this day due to the prolonged heavy rainfall. Scores of homes and several schools sustained damage, and many roads were washed out in Hesperia, Apple Valley, Victorville and Adelanto. Numerous swift water rescues were needed, one of which likely saved four teens trapped in a storm water drain. On 1/19 a tornado went through Seal Beach and Huntington Beach causing local damage including boats in Huntington Harbor, and wind gusts reached 60 mph in San Clemente. Several waterspouts and very strong winds of 93 mph were also reported in Newport Beach and Huntington Beach. On this day the surface pressure fell to an all-time record low of 29.15 inches (987.1 mb) at San Diego Lindbergh Field, the lowest since reliable pressure records began in 1880. Two deaths in Tijuana were attributed to the flooding. A tree fell onto a mobile home in Lakeside, causing one fatality on 1/19.
